State-of-the-art chemical, physical and biological water treatment techniques do not always properly remove some biogenic elements (nitrates, ammonia and phosphates) to reuse or reclaim wastewater. Modern membrane techniques provide high efficiency in removal of suspended and colloidal matter, bacteria and viruses, organic compounds as well as dissolved ions. For wastewater reuse and reclamation application of reverse osmosis provides reduction of BOD, phosphates and ammonia without application of biological treatment. To successfully apply reverse osmosis to treat wastewater, adequate pretreatment is required. Often pretreatment costs even exceed reverse osmosis facilities costs. Long research in fouling and scaling mechanisms revealed that fouling rates are dependent not only on hydrodynamic factors, but on membrane properties and channel configuration as well. Therefore, development of a new type of membrane channel with improved hydraulic and fouling characteristics enabled us to present efficient water treatment techniques for wastewater treatment and reclamation. Schematic flow diagrams are presented for different wastewater treatment cases, such as car washing and laundry effluent as well as domestic wastewater treatment and reuse.

PL

Dostępne techniki chemicznego, fizycznego i biologicznego oczyszczania nie zawsze są w stanie efektywnie usuwać związki biogenne (azotany, azot amonowy, fosforany) w celu ponownego użycia oczyszczonych ścieków. Nowoczesne techniki membranowe zapewniają wysoką efektywność usuwania zawiesiny rozpuszczonej i koloidalnej, bakterii, wirusów, związków organicznych i rozpuszczonych jonów. Zastosowanie techniki membranowej w celu odzysku wody ze ścieków nie wymaga stosowania biologicznego oczyszczania ścieków. Efektywne zastosowanie procesów membranowych wymaga wstępnego oczyszczania ścieków, którego koszty mogą przewyższać te związane z eksploatacją membran.
