What Makes an Effective Odor Control Cover System Design?

A common side effect of wastewater treatment processes is the unpleasant odor that can linger near the plant. Neighbors, offended by the odors, expect a resolution. This white paper examines potential solutions to the odors produced by wastewater treatment plants and presents specific considerat...

Inline Sludge Screens – Municipal and Industrial Applications

How do I remove screenings from my sludge? Even when screens are installed at the head of a treatment facility, debris always ends up in the sludge. Plastic parts and fibrous materials can cripple operation of important downstream technologies. The Huber Technology Strainpress® can effectively re...

Model Development, Calibration and Simulation of the Continuous-Flow Sequencing Reactor for BNR Applications

The complexity of biological activities and the number of process variables important to nutrient removal in wastewater treatment systems require the use of process simulation models. The utilization of advanced activated sludge process simulation models has become an increasingly powerful tool f...

Automated Wireless Monitoring of Water Distribution Systems

Water utilities do a great job of producing good quality drinkable water in their processing plants then push it out into their distribution system where little is known. The primary reason is that monitoring the water distribution infrastructure has been traditionally difficult and expensive. T...

Infrared Analysis Reduces Regulatory Fats, Oil and Grease (FOG) Testing Costs and Provides Fast Results

Fixed filter infrared (IR) analyzers have been used to test oil levels in produced water on offshore drilling platforms for over 45 years.  For industrial wastewater professionals a rapid on-site infrared test can be invaluable--saving money, time and SSOs by catching wastewater over the reg...

Fine Screening Equipment as the First Line of Defense

It can be argued that the headworks of a plant might be the most critical place in a Waste Water Treatment Plant.  What happens there will greatly influence the downstream process of the WWTP.  More specifically, it is the operation of screenings and screenings handling which will have ...

Economical, efficient and effective mixing: Three approaches to controlling odor in wastewater treatment ponds

Wastewater treatment operators have several options for reducing pond odors, from increasing aeration to applying chemicals to perfuming the air. Too often these solutions are expensive and ineffective. Another alternative—long-distance mixing—has emerged as an economical, effective solution for ...

All Elastomeric Pinch Valves for Isolation, Throttling and Stopping Centrifical Pump Cavitation in Raw Sewage and Sludge in Gravity Lines, Force Mains, Lift Stations, Wastewater Treatment Plants and Flow Equalization

This white paper is a brief discussion of the techniques and use of all elastomeric pinch valves to rectify common problems found in valve applications in gravity sewer lines, force mains, lift stations, wastewater treatment plants and flow equalization in the isolation, control and throttling of...

Level Measurement In A Septic Waste Transfer Station Day Tank

Solids and wastewater from residential septic tanks must periodically be removed and transported to a wastewater treatment plant for processing. While awaiting treatment, the waste is typically stored in a sludge tank, the level of which must be continuously monitored to prevent drying up or over...

Water layering and full-depth mixing: How water layering affects tank water quality--and why full-depth mixing is one solution

Most potable water quality problems occur in storage tanks, not in the pipeline. These problems—common in chlorine and chloramine systems, warm or cold climates—can range from temperature stratification, dead zones and short-circuiting to biofilm build-up, loss of residual and, in northern climat...

Demin Water System for New PDVSA Power Plant

In 2013 Pure Aqua, Inc. successfully supplied, a demin water (boiler feed) system to PDVSA (Venezuelan government).  The water is used for boiler feed, a new power plant currently being constructed.  Pure Aqua provided packaged/skid mounted equipment consisting of Multi-Media Filters, R...

That Precious Wet Stuff

Flow and level measurement experts KROHNE have released a white paper outlining the drivers and benefits of increased water monitoring. Also discussed is the company's battery-powered, stand-alone WATERFLUX meter and how it helps utilities achieve their water measurement objectives.    ...
