METHOD OF CLARIFYING WATER Russian patent published in 1998 - IPC

FIELD: mineral dressing. SUBSTANCE: invention relates to sorting, concentration, and separation of flocculated particles in mineral dressing process for clarifying recycling water and when treating industrial, household, drinking, and waste waters. Water is supplemented by flocculant solution and saturated by air bulbs via pneumohydraulic aeration. Afterwards, slimes, air flocculi, and hydrophobic impurities are separated via flotation, while solid particles, slime flocculi, and hydrophilic impurities are settled down from water medium. Water is saturated with air bulbs using pressure water electrochemically treated immediately before pneumohydraulic aeration. Saturation of water is conducted in adjacent zones of the same chamber separated by vertical perforated partitions with gaps under their lower edges. Spray agitation of water is only limited by zones saturated with air bubbles and does not reach flotation zones. EFFECT: enhanced water treatment efficiency. 2 cl, 3 dwg
