How reverse osmosis works without electricity

Reverse osmosis needs pressure, not power. Conventional machines add an electric booster pump to create that pressure — KomiBright removes the need for it.

Through self-stabilising valves, an integrated flow restrictor and a low-resistance modularised waterway, ordinary municipal tap pressure (from 1.5 bar) is enough to drive water through a 0.0001 μm RO membrane. The same design flushes the membrane automatically, extending its life — all with zero watts.

Three stages to pure water

PP sediment layer

The pleated PP layer removes dust, rust, sand, sludge and other suspended particles.

Activated carbon block

Precision carbon removes residual chlorine, odours and volatile organic compounds.

0.0001 μm RO membrane

The membrane removes dissolved salts, heavy metal ions, bacteria and viruses — leaving pure water.

What the pumpless design changes

  • No booster pump — the most failure-prone part is simply gone
  • Auto membrane flushing without power
  • One compound filter replaces 3–5 cartridges
  • Yearly, tool-free filter replacement by anyone
  • Silent operation, no power socket required
  • Food-grade PP5 materials throughout

Technical questions

How can a reverse osmosis system work without electricity?
Reverse osmosis only needs pressure, not electricity. Conventional RO machines add an electric booster pump; KomiBright systems are engineered with innovative self-stabilising valves, an integrated flow restrictor and a low-resistance waterway so that normal municipal tap pressure (from 1.5 bar) is enough to push water through the 0.0001 μm membrane.
What water pressure do I need?
C25R-series systems run on 21–70 PSI (1.5–5 bar). The KB-C100R direct-flow system needs 30–70 PSI (2–5 bar); with 3 bars of tap pressure it needs no pump kit at all. If your pressure is lower, a pump kit can be added.
How often do filters need replacing, and can I do it myself?
Once a year — that's the whole maintenance schedule. One compound filter and one membrane, both designed for tool-free replacement in minutes. No technician visit needed.
What does 0.0001 μm filtration actually remove?
The RO membrane removes dissolved salts, heavy metal ions, bacteria, viruses and organic contaminants. Upstream, the compound filter removes sediment, rust, residual chlorine, odour and volatile organic compounds.
