The Science

How Reverse Osmosis Works

RO pushes water through a semi-permeable membrane at high pressure, blocking up to 99% of dissolved salts, heavy metals, bacteria and contaminants — leaving only pure water molecules through.

1

Raw Water In

Borehole, tap or tank water enters the system — may contain salts, fluoride, iron, bacteria or heavy metals.

2

Pre-Filtration

Sediment filter (5µm) and activated carbon block remove suspended particles, chlorine and odours that could damage the membrane.

3

High-Pressure Pump

A pump pressurises the water to force it through the RO membrane — typically 8–15 bar for brackish water.

4

RO Membrane

The semi-permeable membrane rejects up to 99% of dissolved salts, fluoride, nitrates, heavy metals and microbes.

5

Pure Water Out

Clean permeate water flows to your storage tank or tap. Reject brine is discharged to drain.

Client Feedback

What Our Clients Say

★★★★★
"Our borehole water in Kahawa had a TDS of over 1,400ppm — salty and undrinkable. Hydroseal installed a 1,000GPD RO plant and now our 120 units all get clean water. The best investment we've made for this estate."
