Purification Process
Activated Sand Filters (ASF)
The raw underground water first passes through the sand filter. This process essentially copycats a natural spring whereby the fresh water travels through layers of large rocks and trickles down through sand to remove any final turbidity.
Activated Carbon Filter (ACF)
The next step is the Activated Carbon Filter, which removes any residual chlorine taste, odor and color. This filter uses coconut shell based carbon, which is the best type for water purification.
Reverse Osmosis (RO)
The filtered water is then subjected to the reverse osmosis system, which uses high pressure to push the pre filtered water through semi porous membranes. This process removes 99.9% of unwanted dissolved solids, chlorine and other objectionablecharacteristics.
Ozonation
Finally the water is infused with ozone gas, which is a process that removes all types of microorganisms in the water long after it is bottled. This ensures KISIMA water is safe throughout its entire sale cycle.
Ultraviolet Light (UV)
The purified water then passes through food grade stainless steel pipes fitted with UV lights which penetrate through, ensuring if at all any bacteria or pathogens escaped the RO process, their DNA is destroyed.
