Reverse Osmosis 5 Stage water filter system without pump

The BG-RO501 is a household-grade, 5-stage reverse osmosis (RO) water purifier that delivers clean, safe drinking water by removing harmful contaminants commonly found in municipal and borehole water. With no pump required for homes with water pressure of 3 bar or more, this system is ideal for daily household use.

Why You Need a Water Purifier

• South Africa is a water-scarce country with growing demand and deteriorating water quality

• Recycling and pollution from sewage, mining, and industry have made tap water a potential health risk

• Installing a home water purifier eliminates these risks and transforms tap water into a health benefit

How Reverse Osmosis Works

• Removes 99% of bacteria and viruses

• Removes 95% of chemicals and heavy metals

• Uses a semi-permeable membrane that filters down to 0.0001 microns

• Continuously flushes membrane to prevent bacterial buildup

• Produces ±10 litres per hour with ±12L storage tank for constant availability

5-Stage Filtration Process

• Stage 1: 10" Sediment Pre-Filter (5 Micron) – Removes large visible particles like rust, dirt, and mud

• Stage 2: 10" GAC Carbon Pre-Filter – Removes chlorine, pesticides, lime, and ozone

• Stage 3: 10" Carbon Block Filter (5 Micron) – Reduces chlorine taste, fine sediment, and heavy metals like lead and copper

• Stage 4: 75GPD TFC RO Membrane – Filters out bacteria, viruses, parasites, pesticides, herbicides, and metals; self-cleaning to prevent clogging

• Stage 5: T33 Inline GAC Post Filter – Improves taste, removes chlorine, hydrogen sulfide, and organic odours

Feed Water Requirements

• Minimum pressure: 3 bar (if pressure is lower, choose a system with a booster pump)

• Ideal for municipal water or borehole water that meets basic pre-treatment standards

• Operating temperature: 8°C – 27°C

• pH Range: 3 – 11

• Total Dissolved Solids (TDS): <1000 ppm for optimal membrane life

Disclaimer: Purifiers intended for household use and limits apply to water quality and quantity. Have your water tested before installing a water purifier to ensure that it is the right solution. It is important to note that the volume of water put through the unit as well as the quality of the water will greatly influence the lifetime of the filters.
