Disinfecting municipal drinking water networks and commercial borehole water supplies across Kenya requires certified chlorine donors to eradicate waterborne pathogens like cholera and typhoid while maintaining residual protection. KIKI'S supplies high-assay Calcium Hypochlorite (65-70%) and Sodium Hypochlorite across East Africa.
For potable water chlorination applications, KIKI'S Industrial Chemicals supplies documented industrial-grade raw materials and specialty formulation chemicals. We provide consistent chemical inputs and technical documentation to commercial operators across Kenya and the East African market.
Potable water chlorination is the addition of chlorine-based chemical compounds to raw water supplies to eliminate pathogenic microorganisms and maintain a protective chemical residual throughout drinking water distribution networks.
Key Facts
Primary Use Cases
Providing safe drinking water to urban centers and rural communities is one of the highest public health priorities in Kenya. Untreated surface runoff and groundwater frequently harbor pathogenic microorganisms—including Vibrio cholerae, Salmonella typhi, and pathogenic Escherichia coli—capable of triggering devastating community disease outbreaks.
Chemical chlorination remains the global gold standard for potable water treatment because it provides both immediate microbial destruction and a vital, persistent disinfectant residual in the distribution network. When chlorine donors—granular Calcium Hypochlorite (65–70%) or liquid Sodium Hypochlorite (10–15%)—dissolve in water, they hydrolyze to form hypochlorous acid (HOCl) and hypochlorite ions (OCl-).
Effective chlorination requires understanding the 'breakpoint chlorination' curve. Initial chlorine additions are consumed by reducing minerals (iron, manganese, hydrogen sulfide) and react with ammonia to form chloramines. Only after this initial chlorine demand is fully satisfied does free available chlorine (HOCl) accumulate. In Kenya, KEBS KS 05-459 mandates a free residual chlorine level of 0.2 to 0.5 mg/L at consumer taps to protect against post-treatment contamination.
Calcium hypochlorite 65-70%, sodium hypochlorite, and chlorine gas dosing systems for municipal and borehole water chlorination.
Raw Water Demand Testing
Conducting laboratory chlorine demand testing on raw water to determine breakpoint dosing requirements.
Chlorine Solution Preparation
Dissolving calcium hypochlorite granules or diluting sodium hypochlorite into dedicated polyethylene dosing tanks.
Proportional Chemical Dosing
Injecting chlorine solution proportionally into the treated water main via diaphragm metering pumps.
Contact Time (CT) Reaction Dwell
Ensuring a minimum 30-minute contact time in clearwells or contact chambers at pH < 8.0.
Free Residual Colorimetric Monitoring
Testing distribution water using DPD colorimeters to verify 0.2–0.5 mg/L free residual chlorine.

COMMERCIAL & TECHNICAL GUIDANCE
Technical and process guidance for potable water chlorination in Kenya and East Africa.
Free residual chlorine refers to uncombined hypochlorous acid (HOCl) and hypochlorite ions (OCl-) actively available to kill pathogens. Total chlorine includes both free chlorine and combined chlorine (chloramines formed with ammonia). Only free chlorine provides fast, effective disinfection.
