The RO process
Pressure in.
Purity out.
Reverse osmosis pushes feed water through a semi-permeable membrane. Water molecules pass through while many dissolved contaminants are rejected into a separate concentrate stream.
Compare systems →Pre-filtration
Sediment and carbon stages help protect the RO membrane.
Membrane separation
Pressure moves water across a fine semi-permeable membrane.
Polishing & storage
Final filtration prepares permeate water for use or storage.
Why reverse osmosis
Clean water,
without the guesswork.
Reduces dissolved solids
RO targets substances that conventional particle filters cannot remove.
Scales with demand
Choose a compact under-counter unit or a high-output industrial plant.
Improves taste & clarity
Multi-stage treatment can reduce salts, sediment, chlorine and other impurities.
Specialist support
Puritech provides product guidance, technical support and South African fulfilment.
Common questions
Clear answers
before you buy.
What does a reverse osmosis system remove?+
A correctly specified RO system can reduce dissolved salts, sediment, chlorine, fluoride and many other contaminants. Results depend on feed water, pressure, membrane condition and system design.
Should I choose a system with a pump?+
A booster pump is useful where incoming water pressure is low or inconsistent. Puritech can confirm the right option for your pressure and required daily output.
Where is payment completed?+
Product selection, payment, order processing and fulfilment are completed on Puritech's website. RO Systems never collects your payment details.
