MBBR (moving bed biofilm reactor) includes the benefits provided by both attached and suspended growth systems. It is a high rate wastewater treatment technology. Purification efficiency is high. MBBR SystemsIt is a reliable and robust process considering capital, operating, maintenance and replacement costs. MBBR 10,000 to 150,000 m³Applicable to wastewater flows between /day. It is a system proven to be effective in eliminating of the chemical oxygen need and of the biochemical oxygen need. MBBR encourages its use. This process can be provided for new casealization treatment works or retrofits of existing wastewater treatment plants that require high treatment efficiency standards without high cost requirements. MBBR Its performance depends on the percentage of media in the reactor, the surface area of biological carriers, dissolved oxygen and organic loading.
