WASTEWATER CHEMICAL TREATMENT
Coagulant
Appearance: Yellowish to light brown liquid
Application: Added in the Reaction Tank as a primary coagulant for water and wastewater treatment
Key Features & Benefits:
- High coagulation and flocculation efficiency
- Effective over a wide pH range
- Produces less sludge compared to traditional alum
- Enhances turbidity, suspended solids, and color removal
- Cost-efficient with lower chemical dosage required
- Easy to handle and apply in liquid form
Flocculant
Appearance: Typically in liquid or powder form
Application: Added after coagulant dosing in the Reaction Tank to aggregate fine particles into larger flocs for easier settling and removal
Key Features & Benefits:
- Enhances solid–liquid separation efficiency
- Improves sludge dewatering performance
- Works effectively with PAC and other coagulants
- Reduces turbidity and suspended solids in effluent
- Cost-efficient due to lower chemical consumption
- Suitable for wide range of industrial and municipal wastewater
pH Enhancer
Appearance: Clear to slightly cloudy liquid (commonly 32%–50%)
Application: Added in the Reaction Tank to increase pH and maintain optimum alkalinity for coagulation, flocculation, and biological treatment processes
Key Features & Benefits:
- Provides fast and reliable pH adjustment
- Enhances performance of PAC and flocculants
- Supplies alkalinity for biological processes
- Prevents corrosion in tanks and pipelines
- Easy to apply with dosing systems
- Cost-effective solution for consistent treatment
Liquid Chlorine
Appearance: Clear to yellowish liquid with a strong chlorine odor
Application: Added in the Disinfection Tank as a disinfectant for treated wastewater
Key Features & Benefits:
- Effective Disinfectant – Kills bacteria, viruses, and pathogens
- Fast-acting with broad-spectrum microbial control
- Easy to dose and apply using standard dosing pumps
- Provides residual chlorine for ongoing disinfection
- Cost-efficient compared to other methods
- Helps comply with DENR/LLDA effluent standards
