Product Description

During lengthy pipeline transportation, collected water is prone to secondary contamination, containing large particles such as silt and rust. A pre-filter provides the initial filtration, serving as the “first line of defense for household water safety.” It removes harmful substances from domestic water, safeguarding family health and extending the lifespan of water-using appliances.

Key Advantages

1.Multi-stage filtration
2.Modular configuration
3.Various housing materials
4.Adaptable to different water sources

Core Filtration Structure

Typical Filtration Flow Structure：
Raw Water → PP → GAC → CTO → Resin → UF → Clean Water

① Stage 1 – PP Sediment Filter
Removes sand, rust, and large particles
② Stage 2 – GAC Carbon Filter
Removes residual chlorine, odors, and organic compounds
③ Stage 3 – CTO Carbon Block
Deep adsorption + precision filtration
④ Stage 4 – Ion Exchange Resin
Softens water and reduces hardness
⑤ Stage 5 – UF Membrane
Removes bacteria, colloids, and suspended solids

Product Line Strategy

1.Solution A – Rainwater Filtration System
Designed to Solve：
Removes particles and organic pollutants
Eliminates bacteria while keeping natural minerals
Filter Configuration : PP → GAC → CTO→UF→UV(optional)

2.Solution B – Groundwater Filtration System
Designed to Solve：
Hard water (scaling)
Iron and manganese
Possible heavy metals
Filter Configuration : PP→Quartz sand / manganese sand filtration (optional)→ GAC → CTO → Resin → UF/RO

3.Solution C – Atmospheric Water Filtration System
Designed to Solve：
No minerals
High risk of contamination during storage
Taste instability
Filter Configuration : PP→ GAC/CTO(optional) → UV → Mineralization filter cartridge(optional)
