Drinking Water Case Studies and White Papers

1. IFAS System Produces High Quality Effluent In East Central Kansas 9/23/2020

   The City of Emporia, in East Central Kansas, recently experienced an increase in population and more stringent effluent permit requirements resulting in a strained wastewater treatment plant. Emporia retained the services of a local engineering firm to evaluate the current and future needs of the system and recommend an economical, sustainable, and effective solution. After evaluating several options, World Water Works’ Integrated Fixed Film Activated Sludge (IFAS) conformed to all the requirements and was selected.

2. Oxidation And AOP: The Last Lines Of Defense Against Harmful Algal Blooms 3/4/2019

   Secondary metabolites of algae — including algal toxins and taste and odor compounds triggered by a harmful algal bloom — can find their way into source water, creating the risk that they will ultimately reach the water treatment plant to cause water-quality problems. Here is a checklist of considerations for mitigating those effects through cost-effective oxidation, or combined oxidization processes, across a variety of source water conditions.

3. Assessing Best Practices For Water Distribution Systems 7/22/2020

   What are the best practices to help water utilities maintain delivery of safe, high-quality drinking water?

4. Water Stressed City Looks At Opportunities To Reuse And Recycle Tertiary Treated Municipal Sewage For Cooling Tower Application 9/23/2020

   Bengaluru, being a water stressed city, was looking at opportunities to reuse and recycle of tertiary treated municipal sewage for cooling tower application in a nearby power plant. Jakkur STP, being a 10 MLD plant based on conventional anaerobic + conventional activated sludge, was identified to supply about 15 MLD of recycled water for the power plant. The entire plant was designed and retrofitted as two process trains of 7.5 MLD. Read the full case study to learn more about why Integrated Fixed Film Activated Sludge technology (IFAS) was determined to be the best suitable upgrade.

5. Understand RF Propagation Of AMR/AMI Systems 9/19/2013

   Most Automatic Meter Reading (AMR) systems installed in utilities use radio frequency (RF) communication. RF communication is also used for two-way radios, wireless supervisory control, data acquisition (SCADA) systems, office wireless networks, routers and cell phones.

6. Has The Ideal Biocarrier Finally Been Developed? 6/1/2017

   In order to improve the efficiency of biofilm technologies, a high-performance biocarrier has been developed, based on requests for ideal carrier characteristics.

7. Product Traceability 11/29/2020

   The Merriam-Webster Online Dictionary defines traceability as “a: to follow the footprints, track, or trail of b: to follow or study out in detail or step by step… c: to discover by going backward over the evidence step by step … d: to discover signs, evidence, or remains of”. At EBAA Iron traceability allows you as the end user or us as the manufacturer to go backward into the production process and discover the signs that reveal the casting properties to the base level.

8. Instrumenting The Water Network: The Time Is Now 4/8/2022

   With the improved capabilities and affordability of today’s sensor technology, now is the time for water utilities to instrument their networks from the source to the customer.

9. Chloramination Monitoring And Control 7/15/2015

   Since the EPA has established that, together with free chlorine, monochloramine is a primary disinfectant, it has been possible to implement the process more intensively. Water that is treated with monochloramine has, depending on the source of the water, fewer problems concerning taste and odor than water treated with free chlorine. In addition, the chemically more stable monochloramine remains longer in the water, thus allowing a long-term disinfecting effect.

10. In-Situ Calibration: Methods And Pitfalls Of Thermal Mass Flow Meter Sensor Field Validation 5/1/2016

    Mid-to-large size facilities and campuses inevitably have hundreds of flow instruments to monitor, maintain, and repair. For a reliability engineer, ensuring that all instrumentation meets ISO 9000 or similar standards is a time-consuming responsibility. By Matthew J. Olin, President & CEO, Sierra Instruments, Inc.
