Promax hybrid is package sewage treatment plant for treatment of sewage water. The promax hybrid system is based on the high-speed bio-degradation using mbbr (moving bed bioreactor) and microfiltration using membrane, which is unique due to its compactness and performance in respect of volumetric efficiency and high quality recycling water to match most stringent norms in terms of bod and tss. These technologies are combined in a prefabricated; skid mounted and standardized tank system with variable length, suitable for overseas transportation in iso freight containers.
