Product Overview
CM Aquatechnik supplies moving bed biofilm reactor (MBBR) systems using high surface-area polyethylene biofilm carriers (500 m²/m³ specific area) for high-rate BOD and nitrogen removal. MBBR is ideal for upgrading existing activated sludge systems without increasing tank volume, and for compact new-build installations with high-strength industrial effluent.
Frequently asked questions
How is an MBBR system sized?
Sizing is based on the BOD and ammonium loads to be removed: the required carrier surface area is calculated from typical removal rates of 5–15 g BOD/m²/day and 0.5–1.5 g NH₄-N/m²/day. The carrier fill ratio (25–67% of tank volume) and the hydraulic retention time (0.5–4 hours) are then set to suit the application.
Can MBBR be used to upgrade an existing activated sludge plant?
Yes. Adding biofilm carriers to existing tanks increases biological capacity without new tankage, and MBBR can save up to 60% tank volume compared with a conventional activated sludge process. This makes it a practical retrofit option for overloaded plants.
How much maintenance do the biofilm carriers need?
Very little. The polyethylene carriers have an indefinite service life and do not need replacing, and a pure MBBR process requires no sludge recirculation. The biofilm is also resilient to shock loads and returns to performance after an upset.
What information do you need for a quotation?
Please tell us your daily wastewater flow, BOD/COD and nitrogen concentrations, wastewater temperature and pH range, and the discharge limits you need to meet. For retrofits, the dimensions and current loading of your existing tanks are also helpful. Send us your requirements and we will prepare a proposal within 48 hours.
