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


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

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