Wastewater treatment for the cosmetics industry - Chemical & Pharmaceuticals
The cosmetics industry accrues many kinds of wastewater. The challenge for wastewater treatment is that product lots are often changing, thus changing the composition of the wastewater. Switching to a new product lot in particular, produces large amounts of wastewater that are contaminated by surfactants, dye, oils and emulsions and high COD concentrations. In addition, wastewaters foam excessively at times.
In addition to developing problem-specific wastewater concepts, DAS Environmental Expert plans and manufactures integrated processes for biological wastewater treatment. The high adaptability of our wastewater technology and systems paired with the high adaptability of the biomass enables to degrade persistent substances and surfactants at little energy input.
Highly loaded stream branches are treated separately. Mechanical separation processes, such as flocculation, filtration and floatation remove first pollutants while customer-specific methods discolour the wastewater.
Treating the wastewater with DAS technology reduces cost by recycling the water, which reduces the amount of wastewater, thus saving sewage charges.
