Santa Monica, CA Case Study The City of Santa Monica shut down the Charnock well fields in 1996 after finding methyl tertiary-butyl ether (MTBE) and later trichloroethylene (TCE) and 1,1-Dichloroethene (1,1-DCE) in the water.

Article: Building Livable Communities Requires More Than Technical Solutions Although sustainable stormwater management practices such as rain barrels and other low impact development techniques are gaining broader recognition and acceptance, we still have a ways to go before they become part of the collective national consciousness. Do your neighbors know about the problems caused by urban stormwater runoff? How can you increase awareness and gain support for sustainable stormwater best management practices (BMPs) in your community? How can you ensure community goals are integrated into the development process? By Jeff Moeller, Senior Program Director, Water Environment Research Foundation (WERF)

Advances In Online Colorimetric Analyzer Technology

Recent technological developments now enable high-accuracy total phosphorus measurement in near real-time, on-line, that reliably matches lab results.

New Septage Receiving Plant Results In Decreased Maintenance

Previous to installing their new septage receiving station, 18-Mile Creek WWTP had very little protection from unknown debris entering their plant from haulers. The plant reports that in the time that the RoFAS Septage Drum and WAP Washpress have been operating, they’ve processed many septage loads without issue.

Successful Screening Pilot At A Major Waste-To-Energy Player

Parkson recently had a very successful pilot test at the facility of a bio-feedstock supplier of waste products turned into fuel. The Rotoshear® unit, equipped with a .060” wedgewire screen, successfully removes solids directly from Industrial Waste Hauling trucks to recover grease. Screening this material before it enters the receiving station allows the facility to focus on proper treatment of the industrial wastewater rather than the expensive downtime to drain and clean their receiving pond.

Solids Optimization In Wastewater Treatment Plants

Traditional municipal wastewater treatment plants typically rely on conventional tests such as Total Suspended Solids (TSS) and possibly Volatile Suspended Solids (VSS) to attempt to quantify biomass.

Low-Cost Computational Fluid Dynamics Modeling For Pump Stations

Avoid pump station failures, protect the environment, and save money through computer simulation.

UV Disinfection And Dechlorination At Cottonseed Processing Facility In Texas

In this case study, learn how a cottonseed processing facility in Texas successfully prevented biofouling in their RO membrane filtration system by installing the HOD UV technology from Atlantium.

Rice University Fights Clogs And Saves $20K Every Six Months

With Xylem's Flygt Concertor solution, Rice University now avoids clogs and callouts caused by grease and debris, as well as costly recurring equipment replacement. 

Evaluating Polychem Fiberglass Flight Scraper Profiles

With six different Polychem fiberglass flight scraper profiles to choose from, Brentwood offers more flight options than any other chain and flight manufacturer. All Polychem flights feature a flat-face design to minimize recirculation of solids and are fabricated from isophthalic polyester resin. They offer flexible solutions to accommodate tank wall variations and can be supplied pre-drilled and notched to account for chain center lines and floor and return rail wear strip locations.

Repair Or Rethink

The Moundsville Wastewater Treatment Plant in West Virginia chooses not to fix a broken blower unit, but rather to correct an outdated approach. The result is a savings of $50-60K a year in energy costs.

Application Note: Building A Baseline In Florida The Florida Department of Environmental Protection (DEP) knows that establishing dissolved oxygen (DO) and nutrient criteria for the state’s water bodies is a challenge – both scientifically and politically

Applying Oxidation Reduction Potential Sensors In Biological Nutrient Removal Systems Oxidation Reduction Potential (ORP) is commonly a misunderstood science. Applying ORP to wastewater treatment is often a considered a mystery and sometimes called “black magic”. By Bob Dabkowski Hach Wastewater Specialist

Magnetic Flow Meter Measures Water For Continuous Mix Concrete Plants

Massive construction projects require a continuous source of concrete to be poured as rapidly as possible. However, trucking in premix is not an option for such large projects. Concrete must be continuously mixed on-site and delivered via conveyor rapidly to the pour site. Accurate and reliable measurement of water is a must for these continuous mix concrete plants.

Dissolved Oxygen Measurement

One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

NEOSEP® Membrane Bioreactor System Simplifies 'Fundamental Necessities' Of MBR

The NEOSEP® MBR system features Kruger’s uniquely designed K-120C and K-240C flat sheet membrane modules.  The modules offer several innovative design features that enhance ease of installation, operation and maintenance.  This includes an integrated central lifting eye, offering an incredibly well balanced module that makes installation and retrieval a simple and stress-free process.

Thermal Flow Meters For Mixed Gas Applications

Fox Thermal Flow Meters use a constant temperature differential (constant Δ T) technology to measure mass flow rate of air and gases.
