The Solution provides a sustainable, profitable and reliable on-site unit for the treatment and purification of pharmaceutical and chemical wastewaters. It provides an alternative for transport and incineration of hazardous wastewater and removes micropollutants such as Active Pharmaceutical Ingredients and endocrine disruptors. The Solution provides a technical and economical feasible answer to the emerging problem of water quality and drinking water availability. The solution combines 3 different complementary technology modules and removes and converts active pharmaceutical ingredients via oxygen and ozone, ozonolysis, into biodegradable compounds that can be further treated in biological wastewater treatment. The solution makes it possible to avoid the discharge of pharmaceuticals into surface water and the environment in general.
