The Bright Side of Biosolids

Posted by WesTech Engineering on Apr 19, 2021 6:55:41 PM

Disposing of excess sludge – the organic remnants of the wastewater treatment process – is a significant economic and environmental challenge for anyone who operates a wastewater treatment plant. The facility needs to treat the wastewater and then remove the biosolids. What if the sludge was not an irritation and instead became a valuable part of the facility’s resource recovery?

Water Reuse: The Potential for Ultrafiltration and Reverse Osmosis

Posted by Melissa Nichols, PE on Apr 1, 2021 5:09:19 PM

A Case for Water Reuse

Recycling water both in acceptance of concept and in practice has steadily increased in recent years. Various factors such as diminishing water supplies, extreme drought, seawater intrusion, population increase, and others have created an urgency for municipalities and industries to explore alternate water supply options. Thankfully, there are innovative solutions, such as membrane systems, that can help facilities looking for reliable water reuse treatment technologies.

Anaerobic Digestion Equipment - Best Practices for Selection and Operation

Anaerobic Digestion has played a key part in turning wastewater treatment plants (WWTPs) into water resource recovery facilities (WRRFs). The byproduct traditionally called “waste gas” is used as biogas - a renewable, clean, green energy source. Some facilities have been able to generate enough to put renewable natural gas (RNG) into a pipeline and/or send power back to the grid.

Reduce Energy Costs Using Dissolved Air Flotation for Waste Activated Sludge Thickening

Posted by Michael Vanderhooft on May 21, 2018 4:22:01 PM

From 1973 to 1976, the EPA and the state of California sponsored a pilot study in Carson, California. The final technical report was completed in 1980 and is available on the EPA’s website, entitled Waste Activated Sludge Processing (PDF), document EPA-600/2-80-147.

Several technologies were tested for the handling of waste activated sludge, but the process endorsed by the report was “that dissolved air flotation be adopted for thickening of waste activated sludge.”
