WSP 12500 GPD Reverse Osmosis System - 4x40"

This reverse osmosis system from Water Softener Plus is designed to help reduce dissolved solids and improve taste in high-demand drinking or process water. It produces up to 12,500 gallons per day, suitable for facilities needing consistent water quality and volume.

The Problem

Your drinking or process water might taste off, or have a noticeable mineral content that affects beverages, food preparation, or equipment performance. If you’re seeing chalky residue in coffee, or your water just doesn’t taste right, it’s often due to dissolved solids—minerals and other substances dissolved in the water that standard filters don’t remove well.

Why It’s Happening

Dissolved solids come from natural sources underground or from pipes and treatment chemicals. They include minerals like calcium, magnesium, and sometimes salts that don’t settle out. The total dissolved solids (TDS) level gives a good measure of this issue. A simple TDS meter test can confirm if your water has elevated solids causing taste or process problems.

What It’s Costing You to Leave It

Water with high dissolved solids can affect the flavor of drinks and food, leaving a flat or metallic taste. It can also cause scale buildup inside coffee machines, boilers, or other equipment, leading to more frequent cleaning or repairs. Over time, this buildup shortens the life of appliances and may increase detergent or chemical use to counteract water hardness and residue.

How This System Fixes It

This system uses reverse osmosis, a process where water is pushed through a very fine membrane that lets water molecules pass but holds back most dissolved solids. It’s like a fine sieve that reduces minerals and other dissolved substances to improve taste and water quality for your specific needs.

What This System Can Handle

The WSP 12500 GPD Reverse Osmosis System is built for demanding, high-volume use. It can produce approximately 12,500 gallons per day of treated water, making it suitable for larger facilities like food or beverage production, labs, or commercial operations needing consistent water quality at volume. The system is designed to manage continuous operation with automated flushing to keep membranes clear and gauges that let you monitor filter condition easily. It requires feed water that’s been dechlorinated and pretreated to protect the membranes.

What You Actually Get

The system includes five 4-inch by 40-inch reverse osmosis membranes on a 440 series platform, controlled by an NRO ROC2 controller that automates process management and flushing. It has pre- and post-filter pressure gauges to help you keep an eye on maintenance needs. The entire assembly comes mounted on a floor stand and runs on 220-volt power.

Is This the Right Size for You?

This system is designed for large-scale operations requiring over 10,000 gallons per day of purified water. If your needs are smaller, this might be more capacity and complexity than necessary. Conversely, if your operation demands even higher volumes or specific custom configurations, talk to us about sizing options.

Living With It

You’ll need to keep an eye on the pressure gauges to know when prefilters require changing, which helps avoid a drop in performance. The system’s automatic flush reduces membrane fouling but membranes will still require periodic replacement over time. Regular maintenance, typically scheduled based on water quality and usage, ensures steady operation without surprises.

What It Won’t Do

This reverse osmosis system reduces dissolved solids and improves water taste but does not remove chlorine before it reaches the membranes—you need to dechlorinate your feed water separately. It also doesn’t treat issues like iron staining or bacterial contamination directly. Specialized pretreatment or additional equipment would be necessary for those problems.
