• Supplied ready for connection
• Only one wearing part
• For population equivalents of 4 - 50
General Description:
Sewage treatment using the ‘BiPur’ system is achieved via the activated sludge process on a micro scale. Sewage is fed into a two-part sludge reservoir in which solids are retained and consolidate.
The wastewater then passes to the aeration basin via a overflow pipe. Oxidation within the aeration basin is carried out by means of a single fine bubble diffuser. A timer controls the switching on and off of the aeration process in order to achieve both nitrification and denitrification. A circulation system that has been tested and optimised in trials prevents dead areas within the basin, ensuring optimum purification.
The flow then passes via a baffle to the post-clarification basin, where suspended matter rises to the surface. The suspended matter is returned to the aeration basin by means of a fully automatic scum catcher.
The purified effluent leaves the BiPur system via a sampling shaft. All the effluent processing takes place without mechanical assistance.
Built in sensors ensure fully automatic control of the extraction of surplus sludge from the aeration basin, based on monitoring the mixed liqour suspended solids within the aeration basin. The surplus sludge from the aeration basin is extracted using an air lift and is transported for co-settlement with the primary sludge in the first part of the sludge reservoir. This optimises the dry solids content in the sludge reservoir.
In the event of a fault, a control light is activated in the switching cabinet.
The only wear and tear part in the BiPur is the fine bubble diffuser, which can easily be replaced by means of rods. The blower and switching cabinet are located external to the BiPur tank.
