Water Source Solutions
Solution A — Rainwater Filtration
Designed to reduce suspended particles and certain organic contaminants in collected rainwater. Additional disinfection may be required depending on the intended use and water quality.
Reference configuration: PP → GAC → CTO → UF → UV (optional)
Solution B — Groundwater Filtration
Designed to address sediment, hardness, and selected iron, manganese, or heavy-metal concerns through appropriate pretreatment and filter media selection.
Reference configuration: PP → Quartz/Manganese Sand (optional) → GAC → CTO → Resin → UF/RO
Solution C — Atmospheric Water Filtration
Supports post-treatment of water produced by atmospheric water generators, with optional disinfection and mineralization stages selected according to the system design.
Reference configuration: PP → GAC/CTO (optional) → UV → Mineralization Cartridge (optional)
Customization & Procurement
