Wastewater treatment technology

Advanced Oxidation Processes (AOPs) technology.

Using the Advanced Oxidation Processes (AOPs) likely ozone / UV / H2O2 / composite metal catalyst to decades dissolved organic pollutants in wastewater. In AOPs technology, ozone is added to the contaminated water and is activated by the catalyst or UV or H2O2 to form secondary oxidizing species likely hydroxyl radicals. These strong oxidizing free radicals can oxidize the organic pollutants to be CO2 (mineralization) and removal TOC. Our group focus in planning , design and construction for AOPs. We will promote AOPs in application of water reclamation and raise the biodegradability for refractory organic wastewater.

Bio-sludge conditioning reduction technology

Using high-frequency ultrasound to break up biological cells and increase the hydrolysis rate, biological sludge can be converted into a carbon source for microbial growth, thereby achieving the benefit of sludge reduction.

High, medium and low concentration ammonia removal technology

Gaseous ammonia is formed under the condition of high pH by using ammonia, and the ammonia is separated and formed into ammonium sulfate with sulfuric acid by using a super gravity device and a gas-permeable (MD) membrane, which can be reused later. In addition, the use of O3 + catalysts can convert low-concentration ammonia to N2, further replacing biological treatment technology and effectively solving space problems.

Boron wastewater treatment technology

Using chemical coagulation sedimentation combined with fiber adsorption composite technology, boron in the water is formed into sludge, and the system is introduced into an automatic regeneration program, which enables continuous processing and reaches the discharge standard.

Nitrate nitrogen wastewater treatment technology

Based on the volume and quality of wastewater, a biological treatment system can be established to treat nitrate nitrogen by anaerobic denitrification or distillation to form sludge and salt output.

Chemical treatment technology for inorganic wastewater

Using composite chemical precipitation treatment system to remove fluoride, arsenic, nickel, cadmium and other heavy metals in inorganic wastewater. We also apply the fluidized bed crystallizer system(FBC), membrane system, ion exchange system and other special techniques to solve the problem of high strict effluent standard.

Biological treatment technology

Using porous ceramics bioreactor (PCBR), membrane bioreactor (MBR), upflow anaerobic sludge blanket (UASB) reactor and various biological treatment techniques with aerobic and anaerobic condition. It can achieve to remove organics, ammonia, nitrates and phosphates and other pollutants in wastewater.

High-gravity ammonia removal technology

Small footprint, high removal efficiency, easy operation and maintenance. The technology to increase the centrifugal force and increase the removal capacity can handle a wide range of ammonia nitrogen concentration in wastewater, high removal efficiency, small equipment land and high demand, low requirements for wastewater impurities, suitable for pretreatment of high concentration ammonia nitrogen wastewater, which can greatly reduce the back-end system Load of ammonia nitrogen.
