For wastewater of integrate circuits, it is applicable to all wastewater and waste liquid of silicon wafer preparation and processing, chip fabrication, package and testing, and other subdivided trade structures, and provides integrated solutions and services.
For the classification, quality classification, and advanced treatment of the whole plant wastewater, it uses PCR-CHDS, RRR-CuRe, RRR-LWRe and other processes and combines special reagents to meet your discharge requirements and realize the targets of wastewater recycling and sustainable utilization.
Recycling and utilization scheme for RRR-H2SO4 waste concentrated sulfuric acid
Special-type oxydol remover+ integrated reaction kettle
It is applicable to the rapid removal of hydrogen peroxide < 50 mg/L in waste concentrated sulfuric acid, and realizes the recycling of waste concentrated sulfuric acid, achieving a recovery of nearly 100%
Recycling scheme for RRR-TMAH photoresist wastewater
Strippable photoresist + special type resin for TMAH recovery
It can realize TMAH recycling and reduce the load on subsequent biological treatment units.
Advanced fluorine removal of PCR-HiDF fluorine-containing wastewater
Special type fluorine removal agent/fluorine selective resin
Ensuring effluent F-<1 mg/L
Recycling scheme for RRR-CuRe electrolytic recovery of copper-containing waste liquid/wastewater
Concentrating technology + efficient electrolytic recovery device + special type recapture agent
For copper-containing wastewater with different concentrations, it completes the transformation of copper-containing sludge to copper recycling, can recover the copper rod with high efficiency and low energy and realize high-standard discharge
Recovery scheme for RRR-LWRe grinding wastewater with efficient combined membrane
High-speed centrifugation recovery/special filter + coupling double-membrane method
