Portable Parallel Analysis: Streamlining Distribution System Water Testing

One Hach customer used the SL1000 Parallel Portable Analyzer (PPA) to test 6 parameters simultaneously - "all within 8 to 10 minutes."  This customer's previous procedure took 20 minutes just for one parameter.  By cutting down the testing time to 8 minutes, the utility saves ...

How Calibration Capabilities helped provide Cleaner Drinking Water

Having the ability to perform special  calibrations with  customer specific piping allowed for the use of Ultrasoinc metering in UV process.

What Makes Corzan CPVC Piping Systems Superior to PVC

Through the years, piping systems have evolved. The concept of transporting fluids has remained the same, but the piping materials used to distribute said fluids have seen vast improvements. Some of the first pipes were made from clay. Clay was replaced by wood. Metal succeeded wood, and now afte...

Measuring Flow in a Pump Station

Water losses within the distribution system can raise costs for both plants and their customers. As a result, many municipal drinking water and water treatment plants are forced to run operations as efficiently as possible. Water supply issues, budget constraints and environmental concerns have r...

Octave® Science vs. Mag Meters

North American water utilities are rapidly adopting non-mechanical technology as the new standard in measurement. Have you ever wondered what the difference is between an ultrasonic and electromagnetic ('mag') meter? Both types are solid-state, a term used to describe an advanced electronic produ...

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...

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...

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 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 ...
