I.Overview
UPVC (unplasticized polyvinyl chloride, also known as rigid PVC) is mainly used in cost-sensitive scenarios and non-core processes in ultra-pure water systems. It serves as the “economical supporting role” in ultra-pure water systems, playing an irreplaceable role in pre-treatment and secondary water purification processes. Its core value lies in its cost-effectiveness and ease of installation.
II.Main process
Raw Water → Raw Water Tank → Booster Pump → Flocculant/Reducer Dosing → Activated Carbon Filter → Ultrafiltration (UF) → Scale Inhibitor Dosing → Security Filter → 1st Stage High-Pressure Pump → 1st Stage RO → pH Adjustment → Intermediate Tank → 2nd Stage High-Pressure Pump → 2nd Stage RO → Purified Water Tank → EDI Booster Pump → UV Sterilizer → Cartridge Filter → EDI System → Ultra-Pure Water Tank → Transfer Pump → TOC Removal Unit → Polishing Resin → Final Filter → Point of Use
III.Core Application Scenarios of UPVC
Scenarios | Details |
Pretreatment and Primary Pure Water Transportation | Raw water transportation, sand filter/carbon filter pipes, RO product water storage |
Economical Ultra - pure Water Systems | Medical dialysis equipment, laboratory pure water systems, photovoltaic cell cleaning |
IV.Key Performance Characteristics of UPVC
Parameter | UPVC |
Impact on Resistivity | Water quality degrades to 15 - 17 MΩ·cm after use |
TOC Leaching (ppb) | 1 - 5 (initial) → 3 - 10 (long - term) |
High - temperature Resistance | ≤ 40°C (long - term) |
Installation Cost | $10/m (cold glue bonding) |
Service Life | 8 - 10 years |
V.Here is a guideline for you to get a proper quotation
Tell us the raw water/source of water(tap water, well water, or sea water, etc)
Provide water analysis report(TDS , conductivity, or resistivity, etc)
Required production capacity( 5m³/H, 50m³/H,or 500m³/H, etc)
What's the pure water used for( industrial,Food and Beverage,or agriculture, etc )
