WSP Whole House Reverse Osmosis System - Commercial, 500 GPD

When a guest pours water from the tap, they notice a sharp chemical taste or an off smell that’s hard to place. The kitchen sink shows a faint but persistent ring of residue that just won’t scrub away. Coffee brewed with that water tastes flat or metallic. These are signs of dissolved solids and unwanted chemicals in your water.

What’s behind the taste and stains you’re seeing

Your water contains dissolved solids — minerals, salts, and other substances that don’t just sit in plain sight but affect taste, odor, and the way water behaves in your home or business. These come from the source water itself, whether from a municipal supply or a well, and include things like chlorine added to disinfect, organic compounds, heavy metals such as lead, and microscopic organisms. A simple test of total dissolved solids (TDS) in your water confirms their presence and level, giving a clear picture of what you’re dealing with.

How the control head manages your system

The heart of this system is its control head, which smartly manages the flow of water through each stage of treatment. It controls when the system feeds water into the membranes, flushes out accumulated particles, and shuts off automatically to protect itself from running dry — a key safeguard that helps extend the system’s life. Dynamic SmartLight indicators provide clear, visible signals about system status, so you always know how it’s performing. Push-fit connectors simplify installation and future servicing.

The media that cleans your water

Inside the main vessel, a thin-film composite reverse osmosis membrane acts like an extremely fine filter, forcing water through tiny pores that block dissolved salts and many contaminants. Before this stage, granular activated carbon removes chlorine, organic compounds, and odors that affect taste. This combination targets a broad range of issues: sediments, chlorine taste and smell, heavy metals including lead, microorganisms, and various organic impurities that can impact both drinking water and process water quality.

The system’s vessel and capacity explained

The treated water is held in a specially designed vessel sized according to your needs. While the exact dimensions are confirmed when sizing your system, the overall setup is compact enough to fit comfortably in small commercial spaces like cafes or clinics. The system produces up to about 500 gallons of purified water per day—enough to meet the demands of a small business or a busy household requiring consistently clean water.

Who this system is best suited for

This system fits well for small businesses, such as cafes or clinics, where water quality impacts both taste and hygiene. It’s designed to handle moderate water use typical of these settings rather than very large commercial or industrial applications. If you have higher daily water needs or a larger facility, a bigger system would be more appropriate. For smaller households or where flow rate is low, a less complex setup might make more sense. Confirming your flow rate and water analysis helps ensure you have the right size.

What’s included and the next step

The package includes the control head with its SmartLight system, the granular activated carbon filter, and the thin-film composite reverse osmosis membrane in a ready-to-install vessel. The exact tank size and configuration are tailored during ordering based on your water use and test results. Shipping is free within the U.S., and your order comes with expert sizing assistance from people who work in water treatment every day.

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.
