YSI IQ SensorNet | Optimize Your Process & Reduce Operating Costs

Fri, 05 Aug 2022 09:46:23 GMT

Justin: Hello from YSI. I'm Justin King, associate product manager for the IQ SensorNet System. And in this video, I'll be sitting down with Ben Barker, our applications engineer here at YSI. I'll be asking him questions about how the IQ SensorNet System can help water and wastewater plants optimize their treatment processes as well as reduce operating costs. Ben has worked with IQ SensorNet for over five years. During this time, he's gained a lot of knowledge and experience working in the field with plant operators, integrators, and engineers. We'll also be talking about some of the application stories Ben has experienced while he's been in the field. So, how are you doing today, Ben?

Ben: I'm doing well. I'm excited to be here and I'm excited to talk about how IQ SensorNet can help solve process-related issues in wastewater treatment plants.

Justin: Awesome. So, I understand that IQ SensorNet can help plants save in a lot of different ways. For example, energy savings, chemical savings, and even in water savings. Not only that, but the system itself was designed to minimize the cost of implementation, maintenance, and expansion with its modular design.

Ben: Yeah, you're absolutely right. There's a lot of different ways IQ SensorNet that can help reduce operating costs.

Justin: So, I hear from our clients that a common way IQ SensorNet is used is to help with energy savings. Now, how exactly does analytical equipment do that?

Ben: That's correct. Plant energy costs can be expensive if not managed. For example, in a narration basin, blowers that are constantly running use a lot of energy, and all of that energy costs money. In a lot of cases, facilities are over-aerating their process to ensure their immediate compliance. By using an online DO measurement with YSI's FDO dissolved oxygen sensor, a plant can control its aeration process more efficiently by choosing a DO set point, and the blowers can be automatically adjusted based on the sensor's measurement. Take this for example. We have our FDO sensors at a facility in Montana. After installing the sensors, they found that they were over-aerating by four times what they needed. By automatically adjusting the aeration process with a DO set point, they were able to realize huge savings each month.

Justin: So, another way IQ SensorNet can help cut cost is through chemical dosing efficiency. Can you give me some examples of how this is done in a typical plant?

Ben: Yes, absolutely. Chemicals are dosed in wastewater for a variety of reasons, such as chlorine for disinfection, carbon for nitrate removal, or coagulants for phosphorus removal. They can become a large expense for a plant's operating budget. So, being as efficient as possible when dosing chemicals is a very important aspect of plant operations. With an online sensor or analyzer, plants can adjust their chemical dosing to the exact amount that they need rather than overdosing chemicals which can be expensive and cause issues. So, as an example, there is a plant in Wisconsin that is dosing aluminum sulfate to help meet at strict total phosphorus limits. Alum is a very expensive chemical, so efficiently dosing is very important to this plant. Initially, they were taking grab samples and manually adjusting the dosing pumps. This procedure had chemical costs of $10,000 a month. By adding an orthophosphate analyzer to the effluent and automating dosing control based on the analyzer's measurement, this plant was able to cut their monthly chemical costs by $1500, saving them a total of $18,000 a year.

Justin: Minimizing water loss and drinking water plants is an important aspect of day-to-day operations. Now, how is IQ SensorNet being used to keep excess water from being wasted?

Ben: IQ SensorNet can help drinking water plants save water in many different ways. For example, a drinking water plant in Pennsylvania is using IQ SensorNet's turbidity sensor in their filter system to optimize their backwash cycle. Originally, this plant would run two 20-minute rinses during their backwash cycle each day and they would waste all of the water they used. Since installing the IQ SensorNet VisoTurb, they are now able to monitor turbidity measurement and stop the rinse cycle when they reach their target turbidity, which cuts down on the rinse time and saves a lot of water in the process. On average, this plant now saves 1 million gallons of water each day.

Justin: So, we've talked about how using online sensors can save in energy, chemical, and water costs. But how can using IQ SensorNet over other sensor systems save money?

Ben: Well, I'm glad you asked that. IQ SensorNet actually has many features that allow it to be more user-friendly and cost-effective than the competition. To start, we utilize a one-cable design that carries both communication and power. This simplifies installation by minimizing cabling. So, instead of having power and communication cables running throughout the plant, we have one cable that accomplishes both. IQ SensorNet can also accept up to 20 sensors on a single system with a portable controller that can be placed anywhere in the system. This means that you only need a junction box at each measuring location instead of an expensive controller, which drastically reduces the overall cost of the system.

Justin: Well, thanks for taking the time to sit and talk with me about all the benefits that IQSensorNet can offer. I have one last question for you. Where can people find more information about IQ SensorNet?

Ben: That's easy. If you're interested in learning more about the benefits of IQSensorNet, just visit our website at ysi.com/iqsn.

YSI Webinar | Activated Sludge | 3 Things to Improve Process Efficiency

Tue, 19 Jul 2022 12:19:29 GMT

Join YSI’s wastewater expert, Dr. Rob Smith, as he discusses activated sludge at municipal wastewater treatment facilities. Dr. Rob reviews the three things you should know about activated sludge in water resource recovery facilities.

Optimization of the activated sludge process requires careful management of three critical parameters: aeration, sludge wasting, and sludge recirculation. Over the years, wastewater professionals have based their decisions on measurements from batch tests applied to grab samples. The batch measurements are representative of the process but are limited in frequency and subject to interpretation.

On the other hand, direct measurement of water chemistry is performed in the laboratory for demonstrating permit compliance on composited influent and effluent samples. The laboratory measurements provide measurements of important variables like oxygen, solids, ammonium and nitrate, but they are also limited in frequency and the samples are not representative of the process.

Online process monitoring provides the best of both strategies by directly measuring the important variables in representative samples continuously. This webinar discusses online process monitoring and control of activated sludge. Topics include:

Measurement principle
Operation and maintenance
Applications for energy conservation and nutrient removal

Industry-Leading Online Ammonium & Nitrate ISE Sensors for Wastewater

Wed, 22 Jun 2022 08:49:35 GMT

Learn why IQ SensorNet’s ion-selective electrode sensors (ISE) are the best choice for continuously monitoring ammonium and nitrate in wastewater. With many innovative features, the YSI VARiON, AmmoLyt, and NitraLyt provide accurate and reliable measurements to monitor and control the activated sludge process.

These sensors have electrodes selected for only ammonium or nitrate ions, allowing the sensor to determine the concentration of each.

The VARiON gives operators 24/7 data for both ammonium and nitrate to monitor and control their activated sludge process. With this data, operators can see diurnal trends, troubleshoot their activated sludge process, and even directly control processes such as aeration output.

These sensors are perfect for controlling aeration, recirc pumps, or carbon dosing, and can save a lot of money in the process.

The VARiON is the most reliable, accurate, and easy-to-use ISE sensor for wastewater. It has space for four electrodes, one measuring electrode for ammonium and nitrate, a reference electrode, and then one additional electrode for a compensating measurement of either potassium or chloride.

The sensor itself is designed for the rigors of wastewater. It has a stainless steel body and is backed with a two-year warranty. Not only that, this ammonium and nitrate sensor is the first of its kind to be rated for Class I Div 2 hazardous areas, which means these sensors can now go where they couldn't before.

Now most important of all, the VARiON is easy to maintain. Cleaning is incredibly easy, which just requires periodically brushing of the electrodes or using optional air cleaning to clean the electrodes for you. Calibration is also easy as it just requires the periodic matching too a lab sample rather than using any standards. And then replacing the electrodes themselves is easy as it just requires a single tool to replace each electrode as needed rather than all at the same time.

The YSI VARiON, AmmoLyt, and NitraLyt sensors are the perfect tool for continuously monitoring wastewater ammonium and nitrate.

YSI Webinar | Monitoring Oxidation Reduction Potential in Biological Nutrient...

Mon, 09 Sep 2019 13:51:02 GMT

Oxidation Reduction Potential, a Versatile but Misunderstood Wastewater Treatment Monitoring Parameter

Oxidation reduction, or redox, reactions have a central role in wastewater management. Redox reactions are responsible for reducing the oxygen demand, pathogenicity, and toxicity of polluted water and facilitating the removal of nutrients which fuel excess growth of aquatic plants in the environment. Therefore, monitoring redox reactions is critical for the operation of a Water Resource Recovery Facility (WRRF). It is often not practical to monitor all the relevant parameters for every reaction. Alternatively, oxidation reduction potential (ORP) can be used to monitor the process providing insight into the status of redox reactions. This webinar will explain the principles of ORP and provide examples of how it is used to improve WRRF operational efficiency.

Tue, 15 Sep 2015 19:00:00 GMT

Recent events have demonstrated that excess phosphorus in receiving waters can create many serious problems including impairment of drinking water supplies. For this reason and others, incorporation of phosphorus limits into NPDES discharge permits is occurring in many states.

Many facilities are being required to remove phosphorus for the first time and will need to add a process to the flow sheet. A discharge limit of 1.0 mg/L may be achieved most cost-effectively with chemical addition. Enhanced biological treatment may be needed to meet lower limits down to 0.5 mg/L and below. Additionally, biological treatment has other potential benefits.

Regardless of the treatment method, continuous monitoring is essential. Critical parameters include orthophosphate, dissolved oxygen, oxidation-reduction potential (ORP), total suspended solids, and nitrate.

FDO Optical Dissolved Oxygen Sensor for Wastewater | IQ SensorNet | YSI

Sun, 20 Jul 2014 19:00:00 GMT

Digital optical DO sensors with FDO electrodes for use with the IQ SensorNet terminals (http://www.ysi.com/iq).

In the biological nutrient removal process of wastewater treatment plants, continuous and precise measurement of dissolved oxygen concentration is of vital importance for an optimal, trouble-free, operation. The efficiency and energy demand of the purification process, either in the nitrification or denitrification phase, is mainly determined by the performance of the aeration control system.

Using an accurate, reliable, and proven dissolved oxygen sensor as part of your process control regime is essential.

With the YSI FDO (flourescent dissolved oxygen) sensor, you will receive high quality data for an amazing period of time - with minimal maintenance.

The FDO 700 Series IQ sensors employ the following features:

Intelligent sensor cap - The sensor cap (membrane) is individually factory calibrated. Calibration data is stored on a chip that is permanently installed in the sensor cap.

Equal path reference - The optical components and LEDs are identically designed. The benefit is an identical aging process of the components that the sensor can easily compensate for which provides continuous hihg performance.

Green light technology - "Soft" excition light. By stimulating the flourescent reaction in the membrane with lower energy green light, bleaching of the flourescent dye in the sensor membrane is avoided. This means the membrane lifetime is two years - or more.

45 degree technology - It seems so simple. With the FDO sensor's 45° angle on the end, bubbles simply slide right by. Confidently place the FDO sensor in your aeration basin without worrying about bubbles resting on, bursting on, or in any way altering your DO data.

The FDO optical measuring technology is based on an attenuated flourescent signal during a defined time frame. In order to process this time measurement as precisely as possible, the sensor optics are calibrated to the speed of light. This natural constant is defined as the time that a light beam travels from point A to point B - the speed of light. The FDO is precisely calibrated against a physical constant. This technology makes the FDO a non-user calibrated sensor.

This list of no's makes this sensor a yes!

No electrolyte
No calibration needed
No warm-up period
No interferences from hydrogen sulfides and other gases
No flow dependence
No interference from bubbles
Which sensor is right for you?

FDO 700 IQ (700 IQ SW sea water design also available)

Universal optical oxygen sensor for measuring and controlling oxygen input in biological wastewater treatment processes. Rugged DO sensor with a response time of T90 at 25°C in less than 150 seconds and T99 at 25°C in less than 200 seconds. Well suited sensor for DO measurements in biological purification stages at wastewater plants and control of oxygenation. The angle of the sensor prevents signal disturbances from rising air bubbles in aeration tanks.

FDO 701 IQ (701 IQ SW sea water design also available)

DO sensor with improved response times. The 701 IQ has a response time of T90 at 25°C in less than 80 seconds. This sensor is ideally suited for measurement and control in faster processes. The lifetime of the membrane is reduced to ~ 6 months.

VARiON Ammonium, Nitrate and Potassium ISE Sensor | Wastewater Process...

Mon, 02 Jun 2014 19:00:00 GMT

Digital VARiON® Plus ammonium, nitrate and potassium ISE sensor for use with the YSI IQ SensorNet wastewater process monitoring and control system (http://www.ysi.com/iq).

The efficient control of Nitrogen in wastewater systems is possible by making those measurements directly in the wastewater process. The direct ISE measuring technology with the VARiON sensor enables optimization of a plant in respect to process efficiency and energy consumption.

The VARiON Plus 700 Series IQ sensors employ the following features:
Combination measurement - The VARiON sensor can continuously measure ammonium with online compensation of potassium ion interferences by using the potassium ISE. Additionally, you can measure ammonium and nitrate by simply using one sensor.

Measurement/Reference - There is a constant potential with the measuring electrode and the reference electrode. This tension is read as the measured value and prevents interferences.

Matrix adjustment - A matrix effect is caused by all free ions in the wastewater. In general, ions don't act according to their concentration which means the mV signal would be influenced and the end result would be incorrect data. The VARiON sensors can be compensated for this matrix effect. This matrix is unique from site to site so an adjustment can be done by keeping the sensor in process and storing the mV value, taking a physical sample, filtering it and conducting lab analysis and then entering those reference values. Conventional calibration is not recommend because the VARiON is factory calibrated. It can still be calibrated with cal standards but probably won't be necessary.

The City of Dayton, OH utilizes the YSI IQ SensorNet (http://www.ysi.com/iq) to lower preventative maintenance, optimize process, meet permits, and save money in the long run.

Jason Tincu explains their use of DO sensors to fine tune aeration needs while using the ammonium sensors to trim back aeration even further while still completely nitrifying in the system.

The YSI IQ also eliminates the need to have outside professionals onsite and prevents the City from having costly service contracts.

As the City looks into the future, they anticipate tighter restrictions on their permit in regards to phosphorus and they intend to seamlessly add the YSI Orthophosphate analyzer to their existing IQ SensorNet system

The YSI IQ SensorNet 2020 XT is a modular water quality system for a complete sensor network ideal for various installation needs. The modular system can accept additional sensors easily at any time. This is a powerful system to continuously measure water quality parameters anywhere in a facility for process control.

Immediate benefits include better network visibility and management, early detection of network failures, improved compliance with regulatory targets and cost savings (energy, pump/blower maintenance, labor).

The system is capable of measuring:
Dissolved oxygen (optical or electrochemical)
pH
ORP
Conductivity
Temperature
Turbidity - ultrasonic cleaning
TSS (total suspended solids) - ultrasonic cleaning
Ammonium
Nitrate*
Potassium
COD (chemical oxygen demand) - ultrasonic cleaning
TOC (total organic carbon) - ultrasonic cleaning
DOC (dissolved organic carbon share of TOC) - ultrasonic cleaning
SAC (spectral absorption coefficient) - ultrasonic cleaning
BOD (biochemical oxygen demand) - ultrasonic cleaning

*Chloride can be seen in the menu on the terminal but only the last value. No real-time monitoring and control function when used on the NitraLyt or VARiON sensor as compensation for nitrate.

The entire system accommodates up to 20 sensors for the above listed parameters in any combination. Any sensor can also be changed out at any time without re-wiring if another parameter is needed. Simply change sensors (parameters) and start getting data for the new parameter.
