Chemical Free Sewage Treatment
Sequencing Batch Reactor (SBR) technology revolutionized biological wastewater treatment by performing all treatment steps—filling, aeration, settling, and decanting—within a single reactor vessel through timed sequences. This approach eliminates the need for separate clarifiers while providing superior process control and flexibility. However, traditional SBR systems still required chemical coagulants and flocculants to achieve optimal performance, creating ongoing chemical costs and environmental impact.
Membrane Bioreactor (MBR) and Moving Bed Biofilm Reactor (MBBR) technologies represent the current state-of-the-art in biological wastewater treatment. MBR combines biological treatment with membrane filtration to achieve superior effluent quality in compact footprints, while MBBR uses suspended plastic carriers to provide protected surface area for biofilm growth, enabling higher loading rates and improved shock load resistance. Both technologies emerged to address the limitations of conventional activated sludge systems in handling variable loads and space constraints.
