  • Energy Savings At The Aeration Basin
    Energy Savings At The Aeration Basin

    With infrastructure dollars still tightly constricted, Aeration Industries International is focusing its attention on making wastewater treatment as cost-effective as possible. “Eighty percent of a wastewater treatment plant’s energy consumption takes place at the aeration basin,” Michael Ramirez, Director of Marketing for Aeration Industries points out in this Water Online radio interview. “Infrastructure dollars are low, everybody knows that. So we need to look for ways to really save money for the customer.”

  • Automation 101: The Dangers Of Hand/Off/Auto
    Automation 101: The Dangers Of Hand/Off/Auto

    When we automate we invariably offer our clients and their operations staff the benefit of Hand/Off/Auto functionality for all the components on our systems. To those new to automation it allows an operator or maintenance worker to remove a piece of equipment, like a pump or blower for example, from the oversight and control automated controller (MCC, PLC, etc.) and operate it manually while it is still installed.

  • Pilot Studies In North Carolina With Hydrex™ Odor Solutions
    Pilot Studies In North Carolina With Hydrex™ Odor Solutions

    Two municipalities were faced with odor issues and required corrosion prevention in their collection systems. Monitoring in the sewer lines indicated peak H2S atmospheric concentrations of 300-500 ppm. Both clients desired H2S < 20 mg/L to prevent corrosion and preferably lower to prevent H2S odor.

BioMag™ And CoMag™ Systems

BioMag™ And CoMag™ Systems

The BioMag™ System easily integrates with planned or existing facilities, increasing activated sludge system capacity up to 300% without new tankage, providing control over the depth of secondary sludge blankets and enabling high nutrient removal.

Flow Measurement

Flow Measurement

For virtually any liquid, steam, gas or slurry there is a cost-effective flowmeter solution from ABB. Please use the links to find the right flow meter for your application

Wireless PRV Monitoring

Wireless PRV Monitoring

Pressure reducing valves (PRVs) are used throughout water distribution systems to reduce pipeline pressure to a predetermined set point. This decreases water loss and prevents pipe breaks.

OSCAR™ Process Performance Optimizer

OSCAR™ Process Performance Optimizer

Intuitive Graphic User Interface (GUI), combined with the transparency provided by real time monitoring, allows operators to always know actual treatment process conditions. No more guessing — just ask OSCAR™ process performance optimizer. He equips operators with the tools they need to successfully and efficiently operate the WWTP.

Floating Aerator / Mixer

Floating Aerator / Mixer

DO2E Aerator / Mixers are high-efficiency all welded, heavy-duty PVC devices that are unique in several ways. DO2E’s patented products are designed to pull water from significant depths for aeration and mixing. By operating with low-pressure (<1.85 P.S.I.) high-volume airflow, these devices maximize energy efficiency. Our patented products are scalable and multi voltage.

Recordall&reg; Compound Series Meters

Recordall® Compound Series Meters

Recordall Compound Series Meters from Badger Meter combine two metering technologies in one innovative package. A positive displacement chamber measures low flow, while a turbine chamber records high flow. These meters are an ideal choice for facilities that experience rapid and wide fluctuations in water demand, such as hospitals, universities, residential complexes and manufacturing or processing facilities.
