A biological technology used for wastewater treatment process which is suitable for municipal or industrial application. MBBR technology offer an economical solution for wastewater treatment. MBBR technology use the moving bed biofilm reactor in the STP tank to increase the surface area where biological organisms thrive. MBBR wastewater treatment system enables efficient results of the disposal using low energy. The technology is used to separate organic substances, nitrification and denitrification. MBBR design is made of an activated sludge aeration system. The sludge is collected on the plastic carriers which have a large internal surface area. The surface area in the carriers optimizes the contact of water, air, and the bacteria. UUES provides its customers with a wide range of MBBR plants, and upgrading any existing plant using MBBR technology to meet the clients’ required performance.
