Introduction
Kenya is quickly embracing advanced water purification technologies, and Reverse Osmosis (RO) is leading the way. At the heart of every RO system is the RO membrane—the component responsible for filtering out unwanted substances. Whether you’re a homeowner or running a commercial water station, understanding RO membranes and their capacities like 75 GPD or 100 GPD is key to getting clean, safe water every day.
Understanding Reverse Osmosis (RO) Membranes
How RO Works
Reverse Osmosis uses high pressure to push water through a semi-permeable membrane, filtering out contaminants like salts, heavy metals, and bacteria.
Role of the Membrane
The membrane acts like a microscopic sieve. Only clean water passes through, while impurities are flushed away.
GPD Explained (Gallons Per Day)
GPD measures the output capacity of the RO membrane. For example, a 75 GPD membrane can produce 75 gallons of purified water in 24 hours.
Common RO Membrane Capacities in Kenya
75 GPD
Perfect for small households. Affordable and widely available.
100 GPD
A popular choice for medium-sized families or small offices.
300 GPD and Above
Ideal for commercial setups like water refill stations or hospitals.
Choosing the Right RO Membrane
Household Use vs Commercial Use
Smaller GPD membranes work well in homes, while higher capacities are needed for continuous or heavy use.
Matching GPD to Water Needs
Don’t over- or under-buy. Match the membrane size to your actual daily water consumption.
Water Pressure and Compatibility
Ensure your system matches the pressure requirements of the chosen membrane.
