WSP 7500 GPD Reverse Osmosis System - 4x40"

When dissolved solids cloud your drinking or process water, it can leave a persistent off taste and affect everything from your coffee to your cleaning results. The WSP 7500 GPD Reverse Osmosis System is designed to help reduce these dissolved solids and contaminants, delivering cleaner, clearer water at a high output suitable for small businesses or clinics.

How dissolved solids quietly add up to bigger costs in your daily water use

You might notice a subtle bitterness in your drinking water or a faint chemical taste that never quite goes away. Over time, these dissolved solids—minerals, salts, and other contaminants—can build up inside appliances and fixtures. That means your coffee maker may need more frequent descaling, water-using equipment works harder and uses more energy, and detergents don’t rinse as effectively. What starts as a minor nuisance can quietly raise your ongoing costs and shorten the lifespan of your water-dependent devices.

How the control head manages water treatment with smart automation

This system features a control head equipped with the NRO ROC2 controller, which automates the reverse osmosis process. It controls feed water flow, flush cycles to clear the membranes, and shutoff when water production meets demand. This automation helps protect the membranes, keeps the system running smoothly, and reduces waste by managing operation precisely according to your water needs.

The core of clean water: thin-film composite RO membranes

Inside the system, four 40-inch thin-film composite reverse osmosis membranes work to reduce dissolved solids, salts, and many other contaminants. These membranes are designed specifically to reject substances that affect taste and water quality, forcing water molecules through tiny pores that block most impurities. This media is highly effective for producing clearer, better-tasting water suitable for drinking and sensitive processes.

Understanding the tank and system capacity

The system includes a vessel sized to match its high-capacity membranes, although exact dimensions are confirmed when tailored to your needs. It’s built to deliver up to 7,500 gallons of treated water per day, supporting continuous use without frequent interruptions. This capacity means it can handle the demands of small commercial settings where steady, reliable output matters.

Is this system the right size for your water needs?

This reverse osmosis system is suited to small businesses, cafes, or clinics that require a high-volume output of purified water. If your demand is lower, there are smaller systems better matched to save space and reduce upfront costs. Conversely, for larger operations with heavier water use, you might consider systems with even greater capacity to avoid running short during peak periods. Always check your daily water needs and flow rates to ensure the best fit.

Who this size is right for

At 500 gallons per day this is sized for a small business, cafe or clinic.

Size this on your busiest day, not your typical one - production water demand rarely stays flat, and running a membrane system at its ceiling shortens its life.
