WSP Reverse Osmosis System - 220V, 4x40"

This reverse osmosis system from Water Softener Plus (WSP) is designed to reduce dissolved solids in your drinking or process water. It uses a single 4x40-inch membrane and runs on 220 volts, providing around 2,500 gallons of purified water per day with built-in monitoring for water quality.

The problem you’re facing

If your tap water tastes off, has a mineral or chemical aftertaste, or leaves a noticeable film on cups and cookware, it might be due to dissolved solids. These are tiny particles like minerals, salts, and other substances that stay dissolved in the water. You might also notice cloudy ice or a chalky residue in kettles and coffee makers. If you rely on this water for drinking, cooking, or any process where water quality matters, these dissolved solids can be a constant nuisance.

Why it’s happening

Dissolved solids come from the water source itself, whether it’s groundwater or municipal supply. They include minerals like calcium and magnesium, but also salts and sometimes trace contaminants. The only reliable way to confirm their presence is by measuring the total dissolved solids (TDS) level in your water, which gives a number showing how much is dissolved. If that number is higher than you want, your water likely tastes or feels different because of it.

What it’s costing you to leave it

Leaving these dissolved solids untreated means you keep dealing with off-flavors in drinks, mineral build-up on appliances, and possibly more wear on kettles, coffee machines, and other water-using devices. You may use more detergent in cleaning or laundry to counteract the effects. Over time, the buildup can become harder to remove and can shorten the life of some appliances.

How this system fixes it

This system uses reverse osmosis (RO), which pushes your water under pressure through a special membrane with tiny pores that let water molecules pass but block most dissolved solids. The result is water with much lower TDS—fewer minerals and contaminants—giving you cleaner-tasting, clearer water for drinking or processing.

What this system can handle

With a single 4-inch by 40-inch RO membrane, this unit produces around 2,500 gallons of purified water per day, making it suitable for light commercial or larger household needs. It operates on 220 volts and includes a chip controller that manages the filtration process for steady operation. The built-in TDS monitor lets you easily check your water quality anytime, showing how well the membrane is performing. The system’s compact design fits comfortably in small spaces without compromising capacity, making it a good fit for offices, clinics, small restaurants, or anywhere consistent low-TDS water is important.

What you actually get

The system includes the single 4x40-inch RO membrane housed in a compact frame, a chip controller to run the system smoothly, and a built-in TDS monitor for real-time water quality readings. It is designed to operate on 220 volts, suitable for facilities with that electrical supply. The exact installation setup will be confirmed when the system is sized to your water.

Is this the right size for you?

This reverse osmosis system is well suited to light commercial applications or larger homes with a significant need for purified water—up to roughly 2,500 gallons daily. If you require less capacity or only a household-scale system, a smaller RO unit may be a better fit. Conversely, if your water needs exceed this volume, you would want a larger or multi-membrane system instead.

Living with it

Maintenance involves routine checks of the TDS monitor and periodic membrane replacement, which depends on your water quality and usage but typically occurs every couple of years. Filters ahead of the membrane (not included here) will also need changing to protect the membrane. You should expect some effort to keep it running smoothly, but the chip controller simplifies operation.

What it won’t do

This system reduces dissolved solids but does not address issues like microbial contamination, chlorine taste or odor, or hardness minerals that cause scale. For those problems, separate treatments like UV sterilizers, carbon filters, or water softeners would be necessary.
