800G Commercial RO Water Purifier with Four-Stage Filtration | UMEK

In today’s pursuit of high-quality drinking water, Hebei UMEK stands out with advanced technology and craftsmanship, offering a powerful four-stage commercial RO water filtration system — the RO COMMERCIAL QUICK-CONNECT VERSION 800G. This 800GPD reverse osmosis system produces up to 800 gallons of purified water per day, offering excellent water output capacity for commercial and high-demand environments.

Featuring a robust PP + CTO + RO + T33 four-stage filtration process, it effectively removes large particles, chlorine, bleach odors, and more, while retaining trace minerals and enhancing taste. With an operating water temperature of 5–30°C and suitable pressure range of 2.5kg – 4kg, the system delivers a total output of 4000L and a flow rate of 90–110L/H. Product dimensions are 400245700mm, and the packaging size is 830440290mm. Designed for easy installation with a quick-connect interface, this commercial RO water purifier provides a reliable and efficient drinking water solution. Let’s explore the unique filtration technology behind it.

1. First Stage: PP Sediment Filter — The “Frontline Blocker” of Large Particles

UMEK’s first filtration stage uses a PP cotton sediment filter, commonly used in reverse osmosis water filtration systems. This filter is made from non-toxic, odorless polypropylene particles through melt-blown technology. The outer layer has coarser fibers while the inner layer is finer, creating a gradient density structure that ensures superior filtration performance.

This structure efficiently traps iron rust, sediment, insect eggs, red worms, and other large contaminants often found in old municipal pipelines. The high dirt-holding capacity and deep multi-layer filtration create a three-dimensional particle trapping effect. With a low pressure drop (0.4 MPa differential), the filter maintains high flow and remains intact.

It contains no chemical adhesives, ensuring safe and hygienic operation, and offers excellent chemical resistance to acids, alkalis, organic solvents, and oils — ideal for complex water sources. Over time, the visible discoloration of the filter element clearly demonstrates its effective particle retention.

2. Second Stage: CTO Composite Filter — The “Taste Optimizer”

The second stage uses a CTO carbon block filter, crafted from premium coconut shell activated carbon, commonly used in drinking water filtration systems. Molded with food-grade adhesive, its interior contains silver-loaded high-iodine-value carbon, and stainless steel mesh at both ends ensures structural integrity.

This design provides multi-functional filtration: it removes free particles, chlorine, rust, color, and odor, and partially filters out both organic and inorganic impurities — effectively enhancing water taste and safety.

Its advantages are twofold. First, silver-impregnated carbon suppresses bacterial growth, addressing a common issue with traditional carbon filters. Second, its powerful adsorption capacity lightens the filtration load on the RO membrane, prolonging its service life. Whether for residential RO systems or industries like food & beverage or pharmaceuticals, the CTO filter plays a critical role in optimizing water quality.

3. Third Stage: RO Membrane — The “Ultimate Defender” Against Micron-Sized Contaminants

The RO (Reverse Osmosis) membrane is the heart of UMEK’s system, developed using space-grade filtration technology. With a pore size of 0.0001 microns, this membrane is 5,000 times smaller than bacteria and far smaller than pesticide or heavy metal molecules.

This ultra-fine filtration capability allows it to reject bacteria, viruses, organic substances, colloids, pesticides, heavy metals, and nearly all dissolved salts. The desalination rate exceeds 99%, making it one of the most effective water purification technologies available.

The resulting water is clean, safe, and pleasantly sweet. Especially in regions with poor water quality or high pollution, the RO membrane filtration system ensures drinkable water that meets high standards. It's widely used in seawater desalination, space missions, and wastewater recycling, proving its reliability and performance.

4. Fourth Stage: T33 Post-Activated Carbon — The “Finishing Touch” for Water Taste

After three thorough filtration stages, the system adds a final layer: the T33 post-activated carbon filter, made from high-quality coconut shell carbon. This final stage focuses on refining water taste and preventing bacterial regrowth.

While the water is already highly purified, the T33 filter further removes residual odors and fine-tunes the taste, making the output water crisp, sweet, and enjoyable. It ensures that filtered drinking water meets both safety and taste expectations for consumers.

Hebei UMEK’s four-stage filtration RO system—comprising the PP sediment filter, CTO carbon block, RO membrane, and T33 post-carbon—creates a comprehensive and high-efficiency water purification solution. Each stage is designed for a specific purpose, and together they offer safe, great-tasting, and thoroughly purified drinking water.

Choose UMEK for a cleaner, healthier, and more refreshing hydration experience. Perfect for restaurants, cafes, offices, or any commercial environment in need of high-flow, high-quality water filtration.
