Non-Fouling Level Transmitter

In wastewater measurement, accurate readings are essential to ensure proper pump operation. Failures in this area result in unhygienic liquid waste overflow and costly repairs to pump mechanisms. In Newport News, Virginia, several restaurants were built in an area serviced by the same municipal w...

Implementation of Solids Retention Time in Wastewater

Solids retention time (SRT) is a critical activated sludge design and operating parameter. What reasons keep automated SRT control from being more widely implemented? This technique is likely to be of great benefit for overloaded or nutrient removal facilities. Find out more about the concept o...

How to Control Denitrification Using Online Nitrate Sensors

Nutrient removal from wastewater is an increasingly common requirement for water resource recovery facilities (WRRF) and nitrogen and phosphorus are the nutrients being targeted.  Utilities are being encouraged to remove as much nitrogen as possible to comply with mass loading limits or even...

How to Control Activated Sludge Using Online Sensors

The focus of this white paper is the use of online instrumentation for control of wastewater treatment aeration. Activated sludge aeration systems can account for 25 to as much as 60 percent of total plant energy use. Implementation of instrumentation, control, and automation (ICA) is critical to...

City of Ventura Sees Increased Productivity and Reduced Expenses

In the face of shrinking budgets and rising fuel costs, several Ventura city departments combined forces to pursue their fleet management goals.  This includes acquiring an affordable vehicle tracking technology that could help lower maintenance costs, reduce vehicle idling, and improve driv...

5 Keys to Selecting a Mag Meter

When choosing an electromagnetic flow meter, it’s important to consider a selection process that will provide the best possible solution for your flow meter application. Electromagnetic flow meters are typically the meter of choice when considering cost, accuracy, and longevity. Read McCrometer's...

MBBR Implementation Insights

 A top concern among wastewater treatment facility owners is increasing energy efficiency while improving effluent water quality. Municipal facilities must comply with increasingly stringent requirements for biological oxygen demand (BOD), ammonia and nitrogen levels, as well as provide for ...

Eastern Municipal Water District Sees Savings and Increased Productivity in first 6 months

The Eastern Municipal Water District (EMWD) needs to shrink operating costs while still carrying out mandatory projects.  Located in California and forced to establish mandatory water usage restrictions means less revenue.  EMWD must still cover 555 miles providing freshing and recycled...

Drinking Water Analysis Guide

Public Water Systems (PWS), regulated by the United States Environmental Protection Agency (USEPA), provide drinking water to 90% of Americans. Water systems and laboratories testing drinking water for Safe Drinking Water Act (SDWA) compliance must be certified and must use USEPA approved methods...

Goodbye Transmitters! New Analytical Sensor Technology Offers Safe and Reliable Operation

With its SMARTSENS line, KROHNE has unveiled the first family of analytical sensors that eliminates the need for external transmitters, thus allowing users to rule out some of the typical problems that affect analytical measurement.  SMARTSENS analytical sensors realize safety and reliabilit...

Remote Diagnostics Will Reduce Service Costs and Increase Uptime of Filtration Systems Filtration OEMs can use built-in device diagnostics to monitor and maintain automation component performance.

Productivity is more reliable when equipment can be monitored to detect incipient failures and take corrective action before the plant goes down. But many devices, such as analog control valves, pneumatic valve terminals and field sensors, often do not offer diagnostic feedback, or it is not bein...
