A new technological scheme of water treatment is proposed, combining reagent methods with hydrodynamic activation of coagulation, flocculation and sorption processes, with baromembrane methods of purification. A method of organizing the process of filtering water after treatment with reagents using a tangential filter made using self-propagating high-temperature synthesis technology is proposed. Jet agitators - ejectors were developed and investigated, the efficiency of using ejectors as devices for dosing and mixing of reagents with treated water was shown. An experimental model of the installation was created and it was successfully tested on model as well as real polluted waters. Purified water obtained on an experimental sample of the installation fully complies with the hygienic requirements and standards established for drinking water.

© 2020 Published under licence by IOP Publishing Ltd.The work proposes a method of purifying landfill leachate. The method is based on a combination of physicochemical and membrane methods of water purification with the extraction and removal of the main part of the sediment at the initial stage of the purification process. This approach allows reducing the load on the subsequent stages of purification, including reverse osmosis. The paper presents a technological scheme for landfill leachate treatment and sediment transfer to the solid phase. In the process of work, an experimental stand was created, and research was conducted on the treatment of landfill leachate. The results obtained indicate the effectiveness of the proposed method.
