Looking To The Future Of Wastewater Treatment

Evoqua is looking toward the future– and that future is energy-neutral wastewater treatment plants.

The company, which was formally Siemens Water Technologies, recently released the Captivator System, which is on the “cutting-edge” of the anaerobic digestion trend, says Paul Rice of Evoqua in an interview with Water Online Radio.

The system combines two pieces of equipment— the folded flow dissolved air flotation separator (DAF) and the vertical loop reactor (VLR) contact tank.

The two technologies together perform enhanced primary clarification. Organic matter is extracted from raw wastewater and sent directly to anaerobic digestion.

Because the Captivator system requires less energy and can create energy, it has a significantly smaller footprint than other alternatives.

“We like to think it is one of the industry leaders,” says Rice. “After four or five years of intense R&D work what the Captivator allows us to do is produce 40 percent more biogas. If you combine that with saving 40% more in aeration energy, we’re darn close to a net zero energy consuming plant.”
