GRATES OF ASEKO SYSTEM
Supporting tubes (6)
with aerators (5)
are connected with each other into a grate with a common air supply. The
anchored grates are fastened to the bottom of the tank by means of adjustable
Air distribution system , at the air inlet side, is provided
with a T-joint with flanged connections. Air is supplied to each grate
through the choke valve (3)
connecting part (2)
and connecting pipe (4).
The connecting part is usually submerged 1 m under water level in the
tank and connects the upper part of air supply to the grate, made of corrosion-proof
stainless steel, while the connecting pipe (4)
is made of PVC.
Each grate is equipped with a mechanism to drain condensed
water from the air. From the drainage cap (1),
a pipe is led around the tank wall to the bottom of the supporting tube
of the grate.
Anchored grates are intended for tanks where a common air supply to the supporting tubes with aerators and for covered tanks is advantageous.
Depending on the shape and size of the tank and the
