Water Treatment Chemicals
A focused range of professional-grade coagulants and disinfectants for municipal, industrial, mining, and institutional water treatment across Zimbabwe.
PureChem currently supplies four core water treatment chemicals covering essential coagulation, clarification, and disinfection functions. Each product is selected for its proven role in professional water treatment operations.
01
Aluminium Chlorohydrate
A pre-polymerised inorganic coagulant widely used in municipal, industrial, and mining water treatment for efficient clarification and particulate removal.
Role in Water Treatment
Primary coagulant for water clarification. Aluminium Chlorohydrate (ACH) destabilises suspended particles, enabling effective removal through sedimentation and filtration. It is particularly suited to treatment systems requiring reliable coagulation performance with low sludge generation.
Common Applications
- Municipal potable water treatment
- Industrial process water clarification
- Mining process and wastewater treatment
- Low-turbidity and variable-quality raw water sources
- Water treatment plants seeking to reduce sludge volumes
Key Benefits
- High coagulation efficiency relative to dosage
- Low sludge production compared to conventional aluminium salts
- Effective across a wide pH range
- Performs well in cold water conditions
- Suitable for low-turbidity water sources
- Reduced alkalinity consumption
Why Clients Use Aluminium Chlorohydrate
Aluminium Chlorohydrate offers reliable coagulation performance with lower chemical dosage requirements and reduced sludge output compared to traditional aluminium-based coagulants, making it a practical choice for treatment operations focused on efficiency and cost management.

PolyDADMAC
A high-charge-density cationic organic polymer used as a primary coagulant or coagulant aid for effective charge neutralisation and flocculation in water treatment.
Role in Water Treatment
Primary organic coagulant or coagulant aid. PolyDADMAC provides strong cationic charge neutralisation, destabilising colloidal particles and enhancing floc formation. It is frequently used alongside inorganic coagulants to improve overall treatment performance.
Common Applications
- Municipal water treatment and clarification
- Industrial effluent and process water treatment
- Mining water recovery and recycling
- Coagulant aid in combination with inorganic coagulants
- Sludge conditioning and dewatering support
Key Benefits
- Effective charge neutralisation across a broad range of water types
- Performs across a wide pH range
- Compatible with inorganic coagulants for enhanced performance
- Can reduce overall chemical consumption when used as a coagulant aid
- Does not significantly affect water pH or alkalinity
- Versatile across multiple treatment applications
Why Clients Use PolyDADMAC
PolyDADMAC provides versatile coagulation capability and can be used as a standalone coagulant or in combination with inorganic products to enhance treatment efficiency, reduce chemical costs, and improve floc quality.

EPI-DMA
An organic cationic polyelectrolyte coagulant effective for colour removal and organic reduction in potable and industrial water treatment applications.
Role in Water Treatment
Primary organic coagulant for colour and natural organic matter removal. EPI-DMA (Epichlorohydrin Dimethylamine) is particularly effective in treating water sources with elevated colour, dissolved organic content, or natural organic matter that requires targeted removal during treatment.
Common Applications
- Municipal potable water treatment
- Colour removal from surface water sources
- Natural organic matter reduction
- Industrial pre-treatment and process water
- Water sources with high dissolved organic content
Key Benefits
- Effective colour removal at low dosages
- Targeted organic matter reduction
- Suitable for use in potable water treatment
- Reduces dependence on metal-based coagulants
- Can be used independently or in combination with other coagulants
- Low impact on treated water pH
Why Clients Use EPI-DMA
EPI-DMA is particularly suited to water sources where colour and natural organic matter pose treatment challenges. Its effectiveness at low dosages and suitability for potable water applications make it a valuable component in treatment programmes addressing organic-related water quality concerns.

Chlorine Dioxide
A selective oxidant and powerful disinfectant used for water disinfection, taste and odour control, and the management of microbiological contamination across diverse treatment environments.
Role in Water Treatment
Water disinfection and oxidation. Chlorine Dioxide (ClO₂) provides effective microbiological control while also addressing taste, odour, and colour issues in treated water. It is a selective oxidant that maintains effectiveness across a wide pH range, making it suitable for varied treatment conditions.
Common Applications
- Municipal water disinfection
- Industrial and mining process water treatment
- Institutional and commercial water systems
- Taste and odour control in potable water
- Biofilm management in distribution systems
- Borehole and decentralised water treatment
Key Benefits
- Effective disinfection across a wide pH range
- Minimal formation of trihalomethanes and haloacetic acids
- Effective control of taste and odour compounds
- Active against a broad spectrum of microorganisms
- Effective biofilm management capability
- Maintains residual disinfection capacity
Why Clients Use Chlorine Dioxide
Chlorine Dioxide offers reliable disinfection with fewer harmful disinfection by-products compared to conventional chlorination. Its effectiveness across varied pH conditions and its ability to control taste, odour, and biofilm make it a strong choice for treatment systems requiring dependable microbiological control.
