Wastewater treatment system recovers electricity, filters water

10/05/2021

Why is it waste?" asked Zhen (Jason) He, professor in the Department of Energy, Environmental & Chemical Engineering in the McKelvey School of Engineering at Washington University in St. Louis.

Electron-producing microbes power sustainable wastewater treatment

17/12/2020

Researchers have developed a sustainable wastewater treatment system that relies on electron-producing microbial communities to clean the water. The work could someday lead to reduced reliance on the energy-intensive processes that are used to move and treat wastewater, which accounts for as much as two percent of the total electrical energy consumption in the United States.

Engineers discover new microbe for simpler, cheaper and greener wastewater treatment

09/12/2020

Researchers have discovered a new strain of bacterium that can remove both nitrogen and phosphorous from sewage wastewater. Their findings offer a simpler, cheaper and greener method of wastewater treatment.

INTRODUCE ABOUT THE EQUIPMENT FOR OVERCORING ROCK STRESS MEASUREMENTS

27/11/2020

In the period of increasingly developed industrialization and modernization, international projects of international stature appeared in Vietnam more and more. The first is the strong development of underground constructions, so the field of underground construction monitoring needs to meet the high technical requirements of international stature. Foreseeing this development trend, Redriver Engineering & Trading Co., Ltd. with 23 years of experience in the field of monitoring has been...

Biochar from agricultural waste products can adsorb contaminants in wastewater

16/11/2020

Biochar - a charcoal-like substance made primarily from agricultural waste products -- holds promise for removing emerging contaminants such as pharmaceuticals from treated wastewater. That's the conclusion of a team of researchers that conducted a novel study that evaluated and compared the ability of biochar derived from two common leftover agricultural materials -- cotton gin waste and guayule bagasse -- to adsorb three common pharmaceutical compounds from an aqueous solution.

Using electricity to break down pollutants left over after wastewater treatment

16/10/2020

Summary : Pesticides, pharmaceutical products, and endocrine disruptors are some of the emerging contaminants often found in treated domestic wastewater, even after secondary treatment. Researchers have now tested the effectiveness of a tertiary treatment process using electricity.

How to Harness the Power of Biosolids to Make Hydrogen From Wastewater

21/09/2020

Developed by researchers at RMIT University in Melbourne, Australia, the patented technology uses a special material derived from biosolids to spark chemical reactions for producing hydrogen from biogas. The approach means all the materials needed for hydrogen production could be sourced on-site at a wastewater treatment plant, without the need for expensive catalysts.

WASTEWATER MONITORING

16/09/2020

The wastewater monitoring system is very important in assessing the quality of water sources after being treated and prepared for release to the environment.The system will monitor flow and measure water quality through indicators measured at installation points
