Water Treatment Alum 17% (Aluminium Sulfate) for Drinking Water & Wastewater Coagulation
Product Code: KIC-WTC-003
Also known as: Aluminium Sulfate, Alum, Paper Alum, Cake Alum
High-grade Aluminium Sulfate 17% (Alum) primary coagulant for municipal drinking water clarification, industrial effluent treatment, and paper sizing in Kenya.
Aluminium Sulfate (Alum, CAS 10043-01-3) is the most widely utilized primary inorganic coagulant for raw water clarification and industrial wastewater treatment across Kenya and East Africa.
When added to raw water, Aluminium Sulfate hydrolyzes to form insoluble gelatinous aluminium hydroxide flocs. These positively charged flocs neutralize negatively charged suspended clay, silt, and organic matter, causing rapid agglomeration and sedimentation.
KEBS Compliant Water Treatment Chemical
Kiki's Industrial Chemicals Ltd supplies prime Aluminium Sulfate 17% (as Al2O3) in 50kg moisture-proof woven polypropylene bags for municipal water boards, beverage facilities, and industrial effluent plants.
Technical Description
In raw water clarification, Alum operates optimally within a pH window of 5.8 to 7.5. The precipitation of Al(OH)3 flocs adsorbs colloidal turbidity particles and humic color compounds.
Dosing requirements typically range from 10 to 100 mg/L depending on raw water turbidity (NTU) and alkalinity levels, determined via jar testing.
