Description
5 stage RO system Oman: the GWS AquaWave Classic 75 GPD RO System is built for homes and small offices. It is a 5-stage reverse osmosis purifier that makes up to 280 litres (75 gallons) of drinking water a day, with a grooved PP sediment filter, GAC carbon, GWS’s patented BLOCKFREE 2-in-1 filter, a 75 GPD RO membrane and a coconut shell post carbon filter.
Global Water Solutions (GWS) is a global manufacturer of pressure tanks and water treatment products, sold in over 100 countries, with factories in Taiwan and China and an office in Dubai. GWS operations are ISO 9001, ISO 14001 and ISO 45001 certified. UV Water Systems supplies, installs and services GWS products across the Sultanate from Muscat.
How the AquaWave Classic 75 GPD RO System Works
Stage 1, a 5 micron grooved polypropylene filter, removes dirt, rust and sand. Stage 2, granular activated carbon with a 1,000 iodine rating, removes chlorine, taste and odour. Stage 3 is GWS’s BLOCKFREE 2-in-1 filter, designed to protect the RO membrane. Stage 4, the 75 GPD RO membrane, removes dissolved salts, heavy metals, bacteria, viruses and chemicals. Stage 5, an inline coconut shell carbon filter, polishes the taste before the water reaches the faucet. A booster pump keeps output steady when mains pressure is low.

Choosing the Right Model
Water in Oman varies a lot. Municipal water is usually low in TDS but carries chlorine, while well and tanker water can have high TDS, hardness, sand and iron. Before recommending a 5 stage RO system Oman product, we check your water source and, where needed, test TDS, hardness and iron. Send us a photo of your current setup or a water test report and we will suggest the right model and pre-treatment. Read more about water purification.
Why Water Treatment Matters in Oman
Most homes and businesses in Oman store water in rooftop or underground tanks, where it warms up in summer and can pick up sediment, rust and bacteria. Hard water leaves scale on heaters, kettles and taps, and chlorine affects taste. Choosing a 5 stage RO system Oman product from a reliable brand, installed correctly and serviced on schedule, protects your family’s health and your appliances, and saves money on bottled water over time.
