PURPOSE:To well perform water treatment by making the release and growth of the biological membrane on the surface of a contact material well balanced by always supplying air to a contact aeration tank in an amount of 10-50l/min/m<2> per the unit volume of the contact material from the ...
FIELD: water purification. SUBSTANCE: method consists in aeration of water under voltage and cavitation in the zone of working wheel of pump. Aeration degree reaches 0.6-1 of limiting air solubility in water at treatment temperature and corresponding pressure on discharge side of pump. Method may ...
In place of the coagulation treatment, conventional activated sludge method may be applied. In this case, conventional apparatuses for activated sludge method, such as aeration vessel and precipitation vessel, may be used. The dehydrated cake obtained by dehydrating the adsorbent slurry by means of ...
