WSP 12500 GPD Reverse Osmosis System - 4x40"

For a small business or clinic relying on clean, consistent water, the WSP 12500 GPD Reverse Osmosis System is designed to handle large daily volumes with precision. It targets dissolved solids that affect taste and quality, producing up to 12,500 gallons of treated water each day.

When Laundry and Fabrics Don’t Last as They Should

Imagine the way your uniforms, towels, or table linens look after repeated washing. Instead of bright and soft, they come out dull, rough, or with colours fading faster than expected. It’s not just time or detergent at fault. The dissolved solids in your water—the tiny salts and minerals you can’t see—can build up in fibres, making clothes feel stiff and wear out sooner. If coffee tastes flat or tap water leaves a slight film on dishes, these are subtle signs that your water quality is affecting more than just your glass.

How the Control Head Keeps Things Running Smoothly

The WSP 12500 GPD system uses a control head featuring the NRO ROC2 controller. This manages the entire water treatment cycle, including feed, flush, and shutoff functions. It automatically flushes the membranes to reduce fouling, which is the buildup of deposits that can slow your system down or reduce its efficiency. The control head also includes gauges before and after the filters, giving you a quick and clear picture of when maintenance is needed. This setup helps keep your system running reliably and with less downtime.

The Role of the Thin-Film Composite Membranes

Inside the system’s vessel, four 4x40-inch thin-film composite reverse osmosis membranes work to reduce dissolved solids and many other contaminants. These membranes act like a very fine sieve, letting water molecules pass through while holding back salts, minerals, and other particles that affect taste and clarity. This media is chosen for its ability to treat high volumes of water efficiently and with consistent results.

The Vessel and Capacity You Can Rely On

The system includes a floor-standing vessel designed for high-demand use, but the exact size and configuration are confirmed during the sizing process to suit your specific needs. It’s built to reliably produce roughly 12,500 gallons of treated water each day on standard 220-volt power. This capacity makes it well-suited to small businesses like cafes or clinics where water quality and volume both matter.

Who Should Consider This System

This reverse osmosis system is ideal for small businesses, cafes, or clinics requiring a steady supply of purified water at higher daily volumes than a typical home system. If you run a household or facility with lower daily water needs or fewer points of use, a smaller unit might be a better fit. Conversely, larger businesses or facilities with very high water demands should look for bigger systems designed for those scales. Confirming your daily water use and flow requirements with our team ensures you get the right capacity and configuration.
