Aeration Unit
It can increase the oxygen saturation of the water. Water aeration is necessary in water bodies which have anoxic condition. This condition arises because of sewage discharges, agricultural run-off, or over-baiting a fishing lake. Here we have described the specifications related to Aeration unit.
Specification:
- An aeration unit to permit the study of oxygen transfer characteristics of diffuse air systems.
- Comprising a 24.5 litre open tank with variable speed motor driven stirrer paddle and pumped air supply, via a valve and flow meter, to a diffuser.
- Sparger, single and treble air stone difusers are included in the supply.
- A battery powered dissolved oxygen meter provides intrumentation including direct reading of water temperature.
Technical Details:
- Pump: Diaphragm type
- Tank capacity: 24.5 litres
- Flow meter range: 1-12 litres/min
Oxygen/temperature meter ranges:
-5 to 199%DO2
-5 to 25.0%DO2
-5 to 19.99mg/l
-10 to 105°C
- Oxygen probe length: 300mm
- Paddle: Variable sped controlled by D.C. shunt wound motor
- Chemicals required:(not supplied)
- Sodium sulphite
- Cobaltous chloride
- Three diffusers, sparger tube, treble airstone and single airstone, may be separately attached to the aerator tube.
- Variable speed adjustment of the stirrer paddle provides different levels of turbulence in the tank.
