Product Description
During long pipeline transportation, raw water may suffer secondary contamination and carry particulate impurities such as silt and rust. A pre-filter performs primary filtration, acting as the first line of defense for water systems. It removes particulate contaminants from feed water, protects downstream equipment, and extends the service life of water-using appliances.
Core Filtration Structure

Stage 1 – PP Sediment Filter
Removes sand, rust, and large particles
Stage 2 – KDF Media
Removes heavy metals and inhibits bacteria growth
Stage 3 – GAC Carbon Filter
Removes chlorine, odors, and organic compound
Stage 4 – CTO Carbon Block
Deep adsorption + fine filtration
Stage 5 – Ion Exchange Resin
Softens water and reduces hardness
Stage 6 – UF Membrane
Removes bacteria, colloids, and suspended solids
