WSP 15000 GPD Reverse Osmosis System - 4x40"

If your drinking or process water tastes off, or if you’re concerned about dissolved solids affecting its quality, the WSP 15000 GPD Reverse Osmosis System offers a high-capacity solution. Designed to handle up to 15,000 gallons per day, it helps reduce total dissolved solids (TDS) and certain contaminants for clearer, better-tasting water.

The problem you’re facing

Your water might leave an unusual taste in your coffee, give bottled beverages a flat flavor, or cause mineral buildup inside appliances. You may notice a chalky film on glassware or cloudy ice. These are signs that dissolved solids—minerals and other substances dissolved in your water—are affecting its taste and quality.

Why this happens

Dissolved solids come from natural minerals in water sources or from treatment chemicals. They pass through many standard filters because they are dissolved, not suspended particles. The best way to check is a simple TDS test, which measures how many dissolved solids you have. Elevated TDS means the water has a higher concentration of substances that can change taste and cause buildup.

What it costs you to leave it

Leaving dissolved solids untreated affects more than taste. Minerals can form scale inside water heaters and equipment, reducing their lifespan and efficiency. You’ll likely use more soap and detergent for laundry and cleaning because these solids interfere with how suds work. Over time, surfaces get dull or stained, requiring more scrubbing and maintenance.

How this system helps

This reverse osmosis system works by pushing water through a fine membrane that traps dissolved substances. Think of it like a very fine sieve that lets water molecules pass but holds back most dissolved solids and contaminants. The water that comes out tastes cleaner and is better suited for processes that depend on consistent water quality.

What this system can handle

Built for high-demand settings, this system can treat about 15,000 gallons per day. It uses six large 4-by-40-inch membranes to handle a heavy load of water, making it suitable for commercial needs like beverage production, large greenhouses, laboratories, or industrial uses where water quality matters. It’s designed to manage continuous flow and comes with controls that automatically flush the membranes to reduce fouling and maintain performance over time.

What you actually get

The system includes six large reverse osmosis membranes arranged on a sturdy floor stand. It’s equipped with an advanced controller that automates daily operation, including flushing routines to protect the membranes. Pressure gauges before and after the filters give clear, ongoing feedback to help you spot when maintenance is needed.

Is this the right size for you?

This system fits operations or homes needing a large volume of purified water daily—around 15,000 gallons. If your water use is significantly less, a smaller unit might be a better match to avoid unnecessary complexity and cost. Conversely, if you need even higher flow or specialized treatment, this might not cover all your needs.

Living with it

Maintaining this system involves regular checks of the filter pressures and scheduled membrane flushing, all automated to reduce daily hassle. Membranes will need eventual replacement, depending on water quality and use. While this system requires a licensed plumber for installation, once set up, it runs reliably with routine monitoring.

What it won’t do

This system helps reduce dissolved solids and specific contaminants but doesn’t address microbial contamination like bacteria or viruses. If your water source has such issues, you’ll need additional disinfection measures. It also doesn’t soften water or remove large particles; other systems are better suited for those problems.
