WASTEWATER TREATMENT RESOURCES

• Treating Contaminated Groundwater: Advanced Iron Removal System

  The City of Belleville, Ontario was planning on re-developing downtown waterfront property into a public space containing a park and a green space. Unfortunately, the proposed site had a long history as an industrial site – initially for a coal gasification plant from 1854 to 1947 and then as a bulk oil storage facility from 1930 to 1990.

• Decentralized Wastewater Treatment In A Housing Development

  Young’s Cove is a masterfully planned exceptional waterfront community situated in pristine Prince Edward County, on the shores of Lake Ontario. It has panoramic views, a children’s waterpark, miles of pathways, green spaces. It covers 7,000 feet of shoreline and fronts protected wetlands and preserves hundreds of acres of forest with birds and wildlife everywhere.

• Multicore Turbo Blower Demonstration Project A Success In Kansas

  The City of Wichita wastewater utility was recently grappling with a difficult issue. In its updated permits, the State of Kansas imposed several nutrient limit targets — notably on nitrogen and phosphorus — that it knew the city would not be able to reach with the existing treatment systems. When issuing the permits, the state asked the city to optimize its operations to achieve those levels.

• Self-Tuning System Provides Big Leap In DO Control

  The City of Cumberland (MD) wastewater treatment plant could see wild swings in its dissolved oxygen (DO) levels until it replaced its air control system with Aerzen AERprocess, an intelligent airflow control system. Now, the city enjoys vastly improved DO control in individual zones and across the entire process, as well as significant savings on its energy bills.

• Tapping Into Big Savings With More Accurate Polymer Measurement

  Polymers, especially flocculants and other thickeners, can be a major headache for drinking water and wastewater treatment plant managers. Power costs aside, buying polymer often represents the biggest expense of the treatment train. Not only are polymers pricey, but their high level of viscosity also presents a challenge to reliable measurement in varying conditions and at different levels of demand.

• How To Design A Better Carbon-Filtration Solution

  Being forced to add carbon filtration in order to comply with drinking water and wastewater regulations or other extreme industrial filtration requirements is challenging enough. Worrying about performance limitations that the treatment process might impose only compounds the problem. Here is a look at how synthetic carbon technology makes it easier to design a better filtration medium tailored to the most challenging process demands.

• From The 1970s To Today – 4 Key Advances In Coriolis Flow Measurement

  Since the first Coriolis flow sensors were introduced to the marketplace in the 1970s, the technology has evolved considerably. As the installed base for Coriolis grew, the sensors were being called upon to deliver data in environments with increasing levels of complexity. This meant that Coriolis sensors had to adapt and conform to a dizzying array of ever-changing installation requirements, process conditions, communication formats, and configuration parameters. The following article highlights four key advances in Coriolis flow measurement’s journey from the 1970s to today.

• City Of Decatur Implements Siemens SITRANS store IQ For Operational Transparency

  The City of Decatur Wastewater Treatment plant in Texas includes a polishing pond and effluent discharge basin, both of which can be overcome with algae growth depending on weather and environmental conditions throughout the year. At times, the algae overgrowth would plug areas of these systems and restrict or block the flow from the polishing pond and effluent basin, which sit approximately 300 yards from each other.

• How Modern Ultrasonic Controllers Can Help Water Utilities Save On Energy

  In industry today, everyone is looking for ways to conserve a bit of energy and save some money. For instance, consider the energy consumption across the United States just in the water treatment process. With thousands of public water utilities, the amount of energy usage is significant.

• Targeting Need-Based Maintenance To Reduce Sewer Overflows

  Whether addressing sanitary sewer overflows (SSOs), combined sewer overflows (CSOs), or storm sewer systems, the idea of advanced strategic insight is key to minimizing damage or public health risks caused by overflow events. Here is a look at how concentrating on the most at-risk areas first — with a focus on overflow prevention — can offer better control for wastewater utilities of all sizes, as it is doing for the city of Houston, TX.
