Moving bed biofilm reactor CHC-BIO

MBBRfor wastewater treatmentfor industry

Salher biological treatments for the removal of organic matter by moving bed biofilm reactor (MBBR) consist in reactor with cylindrical shape and horizontal or vertical design in GFRP. The technology used is a biological treatment where the biomass is fixed and grows adhered to mobile supports, under appropriate conditions of agitation and oxidation. The supports are made of plastic material, with a high specific surface area (> 500 m²/m³) with density close to 1g / cm³. This technology has the many advantages over the process of low-load activated sludge: Great stability of organic matter degradation processes. Reduction of the biological reactor volume for same quality effluent. Dimensioning of reactors with flexible volumes and filling material depending on the performance required and the current – future loads. High flexibility to face pollutant peak loads and presence of inhibitors, restoring the process in just a few hours. Facilitates secondary settling and no recirculation is required to keep the bacterial population, facilitating the absence of filamentous bulking. Possibility of working with higher ascending speeds. Easy control and operation conditions. The reactor will have different chamber layouts and filling materials according to the requirements of the quality of the effluent, pollutant loads and treatment flows: Settling chambers: simple settling or settling – digestion (Imhoff). Different aeration chambers: aerobic elimination of COD and aerobic of nitrification. Specific plastic filler for different aeration chambers.
