Wastewater & Effluent Treatment
Primary inorganic coagulants, heavy metal precipitants, pH neutralizers, and oxidizing agents for industrial effluent treatment plants (ETP) in Kenya.
Quick Answer — Wastewater & Effluent Treatment
Wastewater and effluent treatment chemicals supplied by Kiki's in Kenya include Aluminium Sulfate 17% for primary coagulation, Calcium Chloride for heavy metal and phosphate precipitation, and Sulfuric Acid 98% and Caustic Soda for NEMA pH neutralization.
Wastewater treatment is the chemical processing of industrial trade effluent to remove suspended solids, heavy metals, toxic organics, and extreme pH prior to discharge.
Key Facts
- •Aluminium Sulfate 17% coagulates organic TSS and lowers COD in industrial effluent.
- •Calcium Chloride precipitates soluble fluorides and heavy metals into pressable sludge.
- •NEMA 2024 regulations enforce discharge standards on COD, BOD, TSS, and pH (6.5-8.5).
Primary Use Cases
Technical Process
Industrial effluent treatment involves multi-stage chemical unit operations: equalization, pH neutralization, chemical coagulation/flocculation, and sludge dewatering.
High-turbidity trade effluent containing colloidal dye, organic COD/BOD, and heavy metals is first neutralized with Sulfuric Acid 98% or Caustic Soda lye to pH 6.5–7.5.
Aluminium Sulfate (Alum 17%) or Calcium Chloride is dosed to precipitate soluble phosphate, fluorides, and suspended solids into insolubilized chemical sludge for dissolved air flotation (DAF) or clarifier removal.
Standard Application Process
- 1
Equalization & pH Neutralization
Homogenize raw factory effluent in equalization tanks and adjust pH to 6.5–7.5 with acid or alkali.
- 2
Chemical Coagulation Dosing
Inject Aluminium Sulfate (100–300 ppm) under flash mixing to break emulsion stability and form micro-flocs.
- 3
Flocculation & Heavy Metal Precipitation
Add Calcium Chloride or organic polymers to aggregate micro-flocs into heavy settling sludge.
- 4
Clarification & Effluent Discharge Testing
Separate sludge via DAF or clarifiers; test COD, BOD, TSS, and pH before final compliant discharge.

Key Performance Advantages
- ✓NEMA 2024 Water Quality Compliance
Ensures treated factory discharge meets mandatory NEMA third-schedule standards for municipal sewers.
- ✓Significant COD & TSS Reduction
Aluminium Sulfate coagulation removes up to 85% of suspended solids (TSS) and organic COD load.
- ✓Heavy Metal & Fluoride Precipitation
Calcium Chloride reacts with soluble fluorides and phosphates to form insoluble precipitates for easy sludge press removal.
