The MBR treatment process is a wastewater treatment technique that combines biological treatment with membrane filtration. In this treatment process, the membranes replace the secondary settling pond found in a typical activated sludge treatment system, thus leading to high efficiency in the separation of solid and liquid, high biomass concentration, and therefore high effectiveness in the removal of nitrate and other organic pollutants. The MBR treatment has the advantages of low residual waste (with suspended particles and turbidity in the effluent being close to zero), high effluent quality, small space requirements and ease of automation.
A2/O is the anaerobic-anoxic-oxic biological nitrate and phosphates removal process, whose biological reaction pool consists of an anaerobic zone, and anoxic zone and an aerobic zone. Phosphateaccumulating bacteria release phosphates in the anaerobic zone and absorb easily dissolvable organic matters such as shorter-chain fatty acids. Denitrifying bacteria transform the nitrates from the backflow into nitrogen and release them into the air through biological denitrification in the anoxic zone. Nitrobacteria transform ammonia from the inflow and other organic sources into nitrates through biological nitrification, oxidise and decompose organic matters and absorb phosphates. The A2/O treatment process enables simultaneous nitrate and phosphate removal with lower total hydraulic retention time when compared to other similar processes, leading to operation stability, high treatment efficiency and low operational cost.
Fenton reaction is a process in which iron and hydrogen peroxide are added together for reaction to generate hydroxyl radicals. Such hydroxyl radicals act as oxidising agent to react with the pollutants for oxidation by destroying the organic compounds. Our fenton reaction process can achieve efficient oxidation precipitation and chromium removal and ensure stability of the concentration of heavy metal ions in the effluent under a sophisticated monitoring system.
Electrochemical treatment is a process in which the electrochemical reaction generated by highfrequency pulsed power triggers a redox reaction in the complex compounds in the wastewater, enabling effective and efficient removal of heavy metals and inorganic complex in the electroplating wastewater and ensuring stable compliance with the discharge standard of treated water.
