AERATED, LIGHTWEIGHT, FOAMED CONCRETE TECHNOLOGY FROM THE
|(1) All waste water is gravity fed into a Septic Tank where the waste undergoes settlement and digestion during a retention period of approximately 24 hours. The settled waste water then flows into the Bio-rotor unit.
This unit is divided into three distinct chambers- Balance Tank, (2) Disc Compartment, (3) Humus Tank, (4) Surge flows of waste water are stored in the Balance Tank and metered at a uniform rate into the Disc Compartment by means of an effluent pump.
As the waste water flows through the Disc Compartment, polypropylene discs are slowly rotated through the air and waste water alternately causing a biomass to gradually form on the disc surfaces which assimilate nutrients from the waste water and oxygen from the air, resulting in a staged reduction of the organic impurities in the waste water as it travels past each disc.
Rotation of the discs cause shearing forces to strip excess biomass from the discs. This is moved through the Disc Compartment with the waste water to the Humus Tank.
The treated waste water undergoes settlement in the Humus Tank (or clarifier). The sludge particles settle to the bottom, and the clear effluent passes over a weir arrangement into the Contact Tank, (5) for chlorination (if and when required by Health Inspector). A Sludge Return Pump, (6) returns settled sludge each hour to the inlet of the Septic Tank for storage.
|1)||Settled sludge is returned to the Septic Tank for storage and digestion.|
|2)||Clean effluent is recycled through the plant which tends to suppress the activities of micro-organisms which emit odours|
|3)||By recycling effluent each night the biomass in the Disc Compartment being fed with stored organics from the Septic Tank. This keeps the micro-organisms at maximum population levels and reduces the problem of treatment plants not being used for extended periods e.g. vacations. Consequently, untreated effluent is prevented from being discharged from the unit when persons return suddenly from extended periods of non-use.|
Advantages of the Bior-rotor Unit
The Bio-rotor Unit is a product developed through extensive research and many years of experience in the sewage treatement industry.
Bio-rotor is a highly engineered S.T.P. utifizing only the strongest components.
Note the following:
1) T.E.EC. Helical Gear Motor and Chain Drive.
2) 40 mm dia Solid Drive Shaft.
3) Plummer Block Bearings.
4) 1200 dia Reinforced Polypropylene Discs.
5) Solid State Electronic Control Panel.
When you buy a Bio-rotor, you have the peace of mind that you are purchasing the best value for dollars in the industry.
