Description
Ultrafiltration system Oman: the GWS UltraWave Max UF20J Ultrafiltration System is built for whole-house and light commercial filtration. It combines a 5 micron grooved sediment filter in a 20″ jumbo housing with a 0.1 micron UF membrane, on a stainless steel stand with timer-controlled auto flush, and delivers up to 58 litres per minute.
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 UltraWave Max UF20J Ultrafiltration System Works
Stage 1 is a 5 micron grooved PP filter in a clear 20″ jumbo housing, so you can see when it is dirty. Stage 2 is a 0.1 micron ultrafiltration membrane that removes fine particles, bacteria and turbidity while keeping healthy minerals, unlike RO. A timer opens the 12 V solenoid drain to flush the UF membrane automatically, and a pressure gauge shows when the pre-filter needs changing (0.7 bar drop). A built-in shock arrestor protects against water hammer.

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 ultrafiltration 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 ultrafiltration 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.
