The BIO-DENIPHO™ method offers a high degree of flexibility as the duration of the main phases and the intermediate phases can be varied within very wide limits. This operating principle is therefore perfectly suited to cope with fluctuations in pollutant loads, flows SIMPLIFIED MANAGEMENT The plant is controlled and monitored by a computerised system allowing continuous monitoring and optimisation of the duration of the aeration and anoxic phases and the recirculation flow. The BIO-DENITRO™ and BIO-DENIPHO™ processes have been thoroughly tested and implemented in hundreds of treatment plants worldwide. A precise knowledge of the operating parameters stems from this experience. The fact that these can be readjusted at any time always guarantees the required effluent quality. This alternating system avoids the recirculation of high flows for denitrification and the need for pumps for this. In connection with optimised aeration control, it provides a considerable energy saving. The processes can be used irrespective of climate, plant size, tank configuration and the type A BIO-DENITRO™ configuration can easily be extended at a later date to BIODENIPHO™.

BIO-DEN ITRO™ BIO-DENIPHO™ and BIO-DENITRO™ are biological treatment processes for removal of carbon, nitrogen and phosphorus from wastewater. The technique used is an original application of the activated sludge principle and involves the control of a sequential treatment of pollution in adjacent activated sludge tanks. The BIO-DENIPHO™ and BIO-DENITRO™ processes, which can be applied in any type of reactors, are very flexible. The former enables removal of nitrogen from the wastewater and the latter nitrogen as well as phosphorus. The BIO-DENITRO™ process comprises two identical activated sludge...
