Micro Pollutants in Wastewater Treatment

Clean Safe Water

Water is composed of ground water and purified wastewater, which is contaminated with micro particles on-trace-level. Those substances originate from everyday substances like drugs, cosmetics, or pesticides and herbicides. Because of increasing population, the pollution on micro scale turns to a real threat in important natural water. Low concentration, so called micro pollutants, cause serious problems to biodiversity and influences the natural food. Thus, aquatic organism decrease. New development introduced a fourth purification stage for wastewater treatment plants utilizing active carbon powder or ozone treatment. This process enables a residual degradation up to 80%.

Process Qualification

Weather the purification was successful or not, is done with comparison of UV absorption spectroscopy before and after the fourth purification stage. Unfortunately, the checked process quality is always in a follow-up mode, and it is displayed on a relative dimension. Because of that, regular lab measurements have to proceeded.

Rascope’s approach

Developments from rascope, addresses this problem and provides an in-line measurement solution. We utilize Resonant Raman Spectroscopy. The technology is well-known, powerful, and reliable for quantitative and qualitative detection of substances. Most advantageous are several magnitude higher Raman signals. Our methods allow us to determine an optimal parameter set for wastewater treatment before the purification stages. Furthermore, it reduces large laboratory efforts and enables highest process accuracy and reliability.
