What is (RO) Reverse Osmosis?

Reverse Osmosis (RO) is a water purification method that pushes water through a very fine filter. This filter blocks dirt, chemicals, bacteria, and even dissolved salts. It's one of the few systems that can turn salty water and borehole water into clean, safe drinking water that tastes fresh and sweet.

Removes salts Removes bacteria Removes chemicals

99.9% Purification rate

Why reverse Osmosis

RO removes both visible impurities and invisible contaminants like salts, fluoride, chemicals, and bacteria. It is powerful enough to purify salty water, hard water, borehole water, municipal water — basically any type of water — and make it safe for drinking and cooking in Kenyan homes.

100%

Clean Water

Great for Borehole Water

Softens hard borehole water, removes bad smell, and filters out excess minerals for cleaner, safer drinking water.

Purifies Salty Water

Eliminates dissolved salts from salty or coastal water, giving you fresh-tasting water every day.

Saves You Money

Say goodbye to buying bottled water. RO gives you unlimited clean water straight from your tap.

Why iClear?

Save big with iClear’s advanced reverse osmosis water purification solutions. Enjoy convenient access to clean drinking water at home or discover our Annual Service Subscription for offices. Reduce your reliance on expensive bottled water and enjoy professional support from our team.

Reverse Osmosis

Reverse Osmosis uses a semi-permeable membrane to help remove dissolved salts, ions, unwanted substances and other impurities from water, providing a reliable solution for improving drinking water quality.

Why Is My RO Purifier Producing Less Water Than It Used To?

A 30 to 50% drop in output flow is usually caused by a clogged pre-filter, low inlet pressure or a faulty check valve, all of which are straightforward to diagnose and fix. How RO Output Works Reverse osmosis systems are pressure-driven. The pump or incoming water pressure forces water across the RO membrane, filling a pressurised storage tank. The system produces a slow, steady trickle into the tank, typically 50–150 litres per day for a household system, which accumulates for on-demand use. When output slows, the tank takes longer to refill and you may run out of purified water during high-use periods. The Seven Most Common Causes of Low Output Cause Symptoms Fix Clogged PP sediment pre-filter Slow flow everywhere; discoloured first stage Replace pre-filter (every 3–6 months) Low inlet water pressure Slow output even when tank is empty Ensure inlet pressure ≥ 40 psi / 2.8 bar Fouled or expired RO membrane High TDS at tap; slow output Test membrane rejection rate; replace if <95% Faulty or stuck check valve Tank drains back when system is off Replace check valve Waterlogged or failed storage tank Rapid fill cycle; water at tap is flat or tasteless Check tank pre-charge pressure (5–6 psi / 0.35 bar); replace bladder if failed Kinked or pinched tubing No output on one line Inspect all tubing runs; remove kinks Cold water temperature Normal in harmless season variation Allow for 10–15% lower output in cold months; no action needed When to Call a Technician If steps 1–5 don't identify the problem, or if output has dropped to near zero, the issue may be a failed pump (in booster-pump systems), a cracked membrane housing or a faulty automatic shut-off valve. A qualified technician can diagnose these with a pressure gauge at each stage of the system. Q: My RO system is only 6 months old, can the membrane already be failing? A: A new membrane can fail prematurely if the pre-filters were not replaced on schedule, allowing sediment or chlorine to reach and damage the membrane. Always replace pre-filters first. Q: Will fitting a booster pump fix my low-pressure problem? A: A booster pump helps if low inlet pressure is the root cause. It won't fix a clogged filter or expired membrane, so diagnose the cause before investing in hardware. Keep your system performing at its best iClear's service team can diagnose and restore your system's output to factory specification. Find out more.

Is Your New Borehole Actually Safe to Drink From?

A newly drilled borehole must be flushed, disinfected and laboratory-tested before use as a drinking water source. Skipping these steps risks exposure to drilling fluid contaminants and geological minerals. What Happens During Drilling That Affects Water Quality Borehole drilling introduces several contamination risks that must be addressed before the water is safe to consume. Drilling equipment carries lubricants, hydraulic fluids and hydrocarbon residues. The drilling process can also mobilise geological materials, fluoride, arsenic, manganese and iron, that were previously bound in rock strata above the aquifer. Additionally, the drilling process disrupts the natural groundwater flow around the borehole, often temporarily drawing in shallower, less-protected water from surface layers. This typically clears within days but must be confirmed by testing. The Mandatory Commissioning Steps Kenya Water Resources Authority (WRA) and KEBS KS 459 specify the following steps before a borehole is approved for domestic use: Step Purpose Who Performs It Yield test (pumping test) Establish sustainable abstraction rate Licensed drilling contractor Development flushing Flush drilling contaminants from the aquifer Drilling contractor Borehole disinfection Shock-chlorinate to kill introduced bacteria Drilling contractor / water engineer Physical-chemical test Test TDS, pH, hardness, nitrate, fluoride, iron KENAS-accredited laboratory Bacteriological test Test for E. coli and coliforms KENAS-accredited laboratory WRA abstraction licence Legal authorisation to abstract Water Resources Authority Source: Kenya Water Resources Authority, Borehole Drilling Guidelines; KEWI Water Quality Lab Services. Common Findings in New Borehole Water High iron and manganese: causes orange/brown staining and metallic taste, aesthetically unpleasant and at high levels poses health concerns. Elevated fluoride: common in Rift Valley geology; above 1.5 mg/L causes dental fluorosis; above 4 mg/L risks skeletal fluorosis. High total hardness: not a health risk but causes scale buildup and interferes with soap and appliances. Elevated TDS: a marker for dissolved mineral load; requires further testing to identify specific parameters. Which Treatment Is Right for Your Borehole? The correct treatment system depends on your laboratory results. Reverse osmosis is highly effective for reducing fluoride, nitrates, heavy metals, and overall TDS. Where iron levels are very high, a pre-treatment iron removal unit is recommended before the RO membrane to extend membrane life. Q: My driller says the water looks clear so it must be safe, is that right? A: Clarity alone is not an indicator of safety. Fluoride, nitrates and many bacteria produce no visible change in water appearance. Laboratory testing is the only reliable method. Q: How long after drilling should I wait before using the borehole? A: At minimum 72 hours after shock chlorination and flushing. Testing results must confirm safety before regular use begins. Start your borehole right iClear assesses your laboratory results and recommends the right treatment solution for your specific water chemistry. Find out more.
