Technical Features

I. 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.



II. Water reclaim system and Ammonia & Tetramethyl ammonium hydroxide (TMAH) recycling technology.
We develops the water reclaim technology for the wastewater of general acid/alkaline, local scrubber and so on to agree the water quality of factory's primary and secondary water. In addition, Ammonia & Tetramethyl ammonium hydroxide (TMAH) recycling technology will be applied to reuse chemicals.

III. 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.

VI. 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.

V. Photoresist and polyimide (PI) recycling equipment /application technology.
This technology has been widely used in a well-known photoelectric TFT-LCD color filters (Color Filer), TFT, CELL PI process. The research team focused on the photoresist composition and its chemical properties analysis by using the company's patent. The composition and chemical properties of recycling liquid photoresist is same to the original photoresists.
