Multi Stage Biological Treatment (MSBT) is an efficient method of domestic and industrial wastewater treatment based on spatial microorganism's succession and trophic hydrobiont chains. These spatially segregated trophic microorganism chains provide for conditions at which microbes are eaten by primary microorganisms while the later are eaten by higher organized fagocitors filtrators of different trophic levels. This spatial microorganism succession provides purification by means of aerobic and anaerobic destructor microorganisms, together with conventional copiotrophs and oligotrophs, thus providing for high purification of wastewater from organic and inorganic impurities.

Advantages:

• Negligible amount of surplus sludge as compared to other solutions.
• High efficient (Patent) oxidation system. Reduce energy consumption by 30% to 65%.
• Low investment cost as no sludge dewatering unit is required.
• No need for sludge treatment- reduces operating costs. Almost 50% less of other conventional treatments.
• Easy Scalability –Modular design that enables to increase the flow without the need of major investment.
• Significant reduction in space compared to other solutions –No need for clarifier and sludge treatment
• No need for return sludge pumping (minimizing electro mechanical component).
• Reducing 90% of the "headache" – Due to the absence of organic sludge.
• Odour free -Can be installed close to residential area
• The system enables excellent tertiary effluent quality using only physical filtration and residual disinfection.
• High effluent quality.
• High modularity.
