Chemical-physical wastewater system, CP system<\/h1>\n<\/div>\n\n
\n

An industrial chemical-physical wastewater system is used for the chemical-physical (CP) treatment of wastewater produced in an industrial plant in order to meet the regulatory requirements<\/a> for the discharge of wastewater into a body of water or a municipal wastewater treatment plant.<\/p>\n\n\n\n

Any commercial or industrial use of water, even on a small scale, also generates wastewater, the discharge of which must be approved by the authorities. Approval for wastewater disposal is generally only granted if the water is pre-treated in accordance with the generally recognized rules of technology (e.g. DWA-M 765) or the state of the art (\u00a7 3 No. 11 WHG in conjunction with Annex 1 No. 13 in conjunction with BAT data sheets). This requires a chemical-physical wastewater system for pre-treatment, which treats the wastewater in the respectively required wastewater partial streams (e.g. chromium(VI) reduction or cyan oxidation) and then finally transfers it to a common treatment, usually in a hydroxide precipitation with an auxiliary additive in the batch or, if necessary, as a continuous flow system. The resulting hydroxide sludge is separated via a chamber filter press or a belt filter and the wastewater is passed through a multi-layer filter. Final cleaning is often carried out using a selective exchanger<\/a> to remove residual metals, possibly with pH adjustment before and after the selective exchanger. Sampling for self-monitoring and plant-related government monitoring is carried out in the final pH control. <\/p>\n\n\n\n
