LC-A0
purestar
Produced from thick-walled Indonesian coconut shells through carbonization, steam activation and multi-stage acid washing purification, this grade features a highly developed micropore structure for excellent removal of trace TOC, free chlorine and disinfection byproducts from ultra-pure water. The acid washing process effectively removes ash and soluble minerals from the raw material, greatly reducing metal ion leaching and conductivity fluctuation from the carbon bed, and protecting downstream reverse osmosis membranes and mixed-bed resin.
Compliant with SEMI F40 standards for ultra-pure water materials, it is suitable for both pre-treatment and polishing stages in semiconductor fab UPW systems, as well as high-purity water systems in pharmaceutical and power generation industries.

Semiconductor Fab UPW Systems: Advanced wafer manufacturing requires water with ppb-level organic and metal contamination control. LC-A0's multi-stage acid washing reduces extractable metals and ash to semiconductor-grade specifications, preventing conductivity spikes and protecting sensitive lithography and cleaning processes.
Industrial Water Reuse & Recycling: Water reclamation and reuse systems demand strict control of residual organics and trace impurities to meet recycling quality standards. LC-A0's ultra-low leachables and stable adsorption performance ensure consistent effluent quality without introducing secondary contaminants in closed-loop water systems.
Power Plant Condensate Polishing: Condensate return systems in thermal and nuclear power plants require removal of trace organics and corrosion products. LC-A0's acid-washed purity prevents boiler tube contamination and maintains turbine efficiency.
High-End Electronic Electroplating: Electroplating solutions are highly sensitive to organic impurities and metallic contamination. LC-A0 removes organic decomposition products without leaching metals that would degrade deposit quality.
Reduces extractables by over 70% compared to standard food-grade coconut shell carbon, releasing no impurities into the water stream.
Pore structure optimized for small-molecule organics delivers more thorough removal of trace TOC in ultra-pure water.
Rinsed with pure water during final production stages with no residual chloride as shipped, avoiding impact on sensitive processes.
Excellent batch-to-batch purity consistency with metal leaching test reports available for every production batch.

Q: What is the difference between LC-A0 and PSD-A0 S for ultra-pure water?
A: LC-A0 is positioned as high-end semiconductor grade with deeper acid washing purification and stricter metal leaching control, intended for the most demanding UPW polishing stages. PSD-A0 S is a general acid-washed grade suitable for drinking water and standard UPW pre-treatment, offering better cost efficiency.
Q: What pre-treatment is required before loading?
A: We recommend forward and backwashing with ultra-pure water until effluent resistivity and TOC stabilize before putting online. Avoid contact with carbon steel equipment during loading to prevent iron ion contamination. For less critical systems, PSD-A0 S requires less intensive pre-rinsing.
Q: In UPW systems, should LC-A0 be placed before or after RO?
A: It is most commonly placed before RO to remove free chlorine and protect membranes. For deep TOC control, an additional polishing carbon bed can be added after RO and before the mixed bed. For pre-RO protection only, GAC-P S may be sufficient.
