FIELD: water supply. ^ SUBSTANCE: invention concerns natural water deironing, degassing and removal of coarse impurities and fine sand. Device includes pipelines for source and flush water supply, treated and flush water and slime discharge, aeration device, partially submerged floating filtering load with gas discharge unit attached to it, upper and lower distribution devices. Gas discharge unit includes pipe mounted so as to allow for variable submersion depth, and control valve. Gas discharge unit pipe features mesh filter in its lower part. Aeration device includes air and water mixing chamber positioned in the centre of aggregate case. Mixing chamber is made in the form of vertical cylindrical tube sealed on top and featuring conical slime collector at bottom, with tangential inlet pipe and vane swirler mounted inside the tube. Vane swirler is made in the form of eight-vane impeller. ^ EFFECT: improved water treatment quality by intensified process of aeration and degassing, reduced consumption of flush water and operational costs, enhanced efficiency of plant. ^ 6 cl, 2 dwg |
