Krasilnikova T. Synthesis of sodium aluminate coagulants and evaluation of their efficiency at water purification

New methods of synthesis of high-performance coagulants - aluminium hydroxochloride using available raw materials have been worked out. Conditions it intensification of processes of clarificationand discoloration of natural waters by means of coagulants have been determined. It has been ascertained that the efficiency of clarification increases at using filtration method at stage of water purification. It has been shown that using coagulants contributes to significant increasing of litter capacity of filters. The evaluation of efficiency of worked out aluminium hydroxochlorides at purification of manufacturing water of industrial enterprises has been carried out. The proceses of purification of recycling water of paper production by methods of desilting and electro-flotation has been studied. The influens of aluminium coagulantes on state of active silt of biological constructions for manufacturing water purification has been determinated. Technological scheme of getting aluninium hidrochlorides from sodium aluminate has been suggested.
