10000 GPD Comm RO Four 4x40 Membranes
Delivering 10,000 GPD of consistent, low-TDS purified water to power your high-demand commercial operations.

The challenge
High-volume commercial facilities face critical challenges when water impurities disrupt operations—scale buildup damages equipment, increases energy costs, and shortens equipment lifespan.
Without reliable purification, businesses risk costly downtime, non-compliance with health standards, and compromised product quality, all of which impact profitability and reputation.
How it works — the technology
The Nelsen 10000 GPD Commercial Reverse Osmosis system employs four 4x40 membranes on the advanced 440 series platform, using pressurized feed water that passes through semipermeable membranes.
This process effectively separates dissolved solids, salts, and contaminants by collecting purified permeate while flushing away concentrated impurities as waste, ensuring continuous delivery of low-TDS water at commercial scale.
Capacity & what it handles
- dissolved solids and salts at high recovery
- contaminants reducing water quality and safety
- scale-forming minerals to protect equipment
- impurities that compromise product consistency
- TDS to meet regulatory compliance standards
