Wastewater Treatment Using Sunlight

Ozone as a Reaction Partner

10-Nov-2020

Chemists at the Leibniz Institute for Catalysis in Rostock discovered the molecular mechanism of a photocatalyst that completely breaks down organic contaminants in wastewater with the help of sunlight. Worldwide, for example, more and more residues of drugs such as anti-inflammatory drugs, ...

New membrane separates small organic molecules

The electrical charge is what makes the difference

05-Mar-2020

A new membrane developed at the Helmholtz-Zentrum Geesthacht (HZG) separates small dye particles or drug substances not only by size but also by their electrical charge. This additional function enables organic molecules with lateral dimensions of one to two nanometres to be such high-efficiently ...

Efficient removal of problem substances

Many wastewater treatment plants do not completely remove chemical substances from wastewater.

21-May-2019

Microcontaminants place a considerable burden on our water courses, but removing them from wastewater requires considerable technical resources. Now, ETH researchers have developed an approach that allows the efficient removal of these problematic substances. In our everyday lives, we all use a ...

Textile dyeing without effluent

Reverse osmosis and ion exchange go hand in hand

14-Feb-2017

Bleaching and dyeing textile fibers and fabrics without causing any environmental pollution through effluent may sound too good to be true. And yet “minimal liquid discharge” (MLD) and “zero liquid discharge” (ZLD) – i.e. the minimization or complete avoidance of liquid waste – are already a ...

Fuel from sewage is the future - and it's closer than you think

04-Nov-2016

It may sound like science fiction, but wastewater treatment plants across the United States may one day turn ordinary sewage into biocrude oil, thanks to new research at the Department of Energy's Pacific Northwest National Laboratory . The technology, hydrothermal liquefaction, mimics the ...
