Solutions for purifying wastewater in the textile industry

The energy sector is looking for alternative ways of energy production. Instead of fossil fuels, we increasingly see bio-based energy sources. In bio-processes, a lot of water is lost. It is a challenge to reuse this wastewater. Both in households and industry, much heat is lost through discharged water. New technological concepts will be developed and evaluated for the integral reuse of industrial waste heat and process water.

Additionally, water itself can also be a source of energy. Certain minerals like methane and acetate are very useful in energy production, as is hydrogen.

Solutions

Uit water kunnen we schone energie opwekken, bijvoorbeeld door gebruik te maken van verschillende zoutconcentraties in zoet- en zoutwater. Het slib dat overblijft na het behandelen van afvalwater is energierijk, ook al kunnen we momenteel slechts een deel daadwerkelijk omzetten in elektriciteit. Een effectieve manier om organische stoffen om te zetten in bruikbaar methaan en waterstof is het inzetten van bacteriën.

We can generate clean energy from water, for example, by using the different salt concentrations in fresh and saltwater. The sludge that remains after wastewater treatment is energy-rich, although we can currently only convert a portion of it into electricity. An effective way to convert organic matter into usable methane and hydrogen is by employing bacteria.
