The chemical industry is one of the most important industries. The industry is defined as the production of raw materials, intermediate and finished products. It includes organic and inorganic basic materials, but also the production of plastics, glass, detergents/personal care products and fine/specialty chemicals such as pigments, coatings/adhesives or crop protection agents.
The petrochemical industry is primarily involved in producing the precursors crude oil/natural gas. Among other things, these precursors are required to produce agricultural chemicals, cleaning agents or rubber/plastics.
Moreover, in addition to production wastewater, cooling or precipitation water also accumulates from rooftops, roads, production areas, transshipment sites or tank depots.
