While it offers advanced treatment capabilities, it is often used as a primary sewage treatment method, providing effective removal of solids and organic matter. However, the high costs associated with membrane maintenance can be a drawback.
Moving Bed Biofilm Reactor (MBBR)
Overview
The Moving Bed Biofilm Reactor (MBBR) process involves biofilm carriers that move freely within the biological reactor, providing a large surface area for microbial growth. This enhances the biological degradation of organic matter, making it an effective sewage treatment plant solution for various applications, including domestic sewage treatment and industrial facilities.
Applications

Anaerobic Digestion
Overview
Anaerobic digestion involves the breakdown of organic matter by microorganisms in the absence of oxygen, producing biogas (methane and carbon dioxide) and digestate. This process is often used in high-strength industrial wastewater treatment and organic solid waste management, providing a dual benefit as a sewage treatment plant and energy producer.
Applications
Treatment of high-strength industrial wastewater
Organic solid waste management
Biogas production for energy recovery, supporting green initiatives and environmental sustainability
