Prozess und Vorrichtung zur Behandlung von undurchsichtigen Verunreinigungen in industriellen und/oder landwirtschaftlichen Abwässern |
摘要 |
Industrial or agricultural effluents are treated to recover the chemicals they contain. Before treatment the effluent (12) has a solid concentration of 1.5 to 3% dry matter. It is passed through a decanting centrifuge (10) which separates the effluent into a supernatent (32) containing fine suspended particles and a sludge (28) containing 20-60% dry matter. The supernatent is filtered through a tangential ultra filtration unit (36) with a pore size of 20-50 nanometers to separate everything except dissolved low molecular weight compounds. The retentate contains 10-30% suspended solids and is mixed (58) with the sludge from the centrifuge. |
