Waste Water Treatment
Solid Waste Treatment
ACRE can provide water treatment technologies for coking waste water and municipal waste water, including standard discharging after bio-chemical treatment and recycling of further treated waste water.
Bio-chemical treatment and oxidation treatment
• A/O bio-chemical treatment technology for degrade NH3-N, phenol and cyanides, etc.
• A/O-A/O technology for improving removal of total nitrogen
• Fenton catalytic oxidation technology for further decomposition of the organic substances hard to be bio-degraded in the waste water.
Deep treatment and recycling technology
• Double-membrane process (UF+RO) for further reduction of the organic substances and removal of inorganic salts
• Adsorption technology or NF separation technology for solving the membrane blockage and aging
• MVR technology for treatment of the concentrates
ACRE can provide municipal solid waste treatment technologies including MSW incineration for power generation, MSW landfill, hazardous wastes (incl. medical waste) treatment and municipal sludge treatment.
