Industry Applications — Water Treatment Chemical Solutions
HydroChemix water treatment chemicals serve a wide range of industries worldwide. Below are our key application areas with recommended treatment programs and real-world performance data.
1. Municipal Drinking Water Treatment
The Challenge
Municipal water plants must consistently produce safe drinking water that meets WHO guidelines and local regulations, handling seasonal water quality variations while controlling operational costs.
Our Solution
- Primary Coagulant: PAC drinking water grade (basicity 60-75%, Al₂O₃ ≥30%)
- Coagulant Aid: Anionic PAM (0.5-1 mg/L) for high-turbidity season
- Filter Media: Quartz sand + Anthracite dual-media filters
- Polishing: Coconut shell activated carbon for taste & odor removal
Performance Data
| Parameter | Raw Water | Treated Water | WHO Guideline |
|---|---|---|---|
| Turbidity (NTU) | 15-80 | <0.5 | <1 |
| Residual Aluminum (mg/L) | – | <0.1 | <0.2 |
| PAC Dosage (mg/L) | – | 12-25 | – |
| Cost per 1000 m³ | – | $8-15 | – |
Client Example: Southeast Asian Municipal Plant (50,000 m³/day)
Switched from aluminum sulfate to HydroChemix PAC: 40% dosage reduction, 60% less sludge, $23,000 annual cost savings.
2. Industrial Wastewater Treatment
The Challenge
Manufacturing facilities face strict discharge limits (COD, heavy metals, TSS) with varying wastewater composition and the need for cost-effective, reliable treatment.
Our Solution
- Primary Treatment: PAC industrial grade (basicity 75-85%) at 50-200 mg/L
- Secondary Flocculation: Cationic or Anionic PAM at 2-5 mg/L
- COD Polishing: COD Remover at 100-500 mg/L for recalcitrant organics
- Heavy Metal Removal: Heavy Metal Capture Agent (DTC type)
- Sludge Dewatering: Cationic PAM for belt press or centrifuge
Performance Data (General Industrial)
| Parameter | Influent | After PAC/PAM | Removal Rate |
|---|---|---|---|
| COD (mg/L) | 500-3000 | 100-300 | 80-90% |
| TSS (mg/L) | 200-1000 | 10-30 | 95-98% |
| Turbidity (NTU) | 50-500 | 3-10 | 94-98% |
| Color (Pt-Co) | 200-800 | 20-60 | 85-95% |
3. Textile & Dyeing Wastewater
The Challenge
Textile wastewater contains high concentrations of dyes, auxiliaries, and salts. It requires robust color removal and COD reduction before discharge or reuse.
Our Solution
- Pre-treatment: COD Remover (200-500 mg/L) to break down recalcitrant dye molecules
- Coagulation: PAC high basicity (≥80%) at 200-400 mg/L
- Flocculation: Cationic PAM (3-5 mg/L)
- Optional: PFS for reactive dye wastewater (better color removal)
Client Example: Bangladesh Denim Factory (2000 m³/day)
Using HydroChemix PAC + CPAM + COD Remover program: Color removal 92%, COD from 1200 to 150 mg/L, meeting ZDHC wastewater guidelines.
4. Mining & Mineral Processing
The Challenge
Mining operations generate large volumes of wastewater with high suspended solids, heavy metals, and extreme pH values. Tailings management and water recycling are critical.
Our Solution
- Tailings Thickening: Anionic PAM (high MW, 15-25 million) at 10-30 g/ton dry solids
- Clarification: PAC or PFS at 100-300 mg/L
- Heavy Metal Removal: Heavy Metal Capture Agent
- Acid Mine Drainage: PAC + lime neutralization
Client Example: Copper Mine, Zambia
APAM for tailings: Underflow density increased from 45% to 58% solids, water recovery improved by 22%, reduced fresh water intake by 800 m³/day.
5. Oil & Gas Industry
The Challenge
Produced water treatment requires breaking stable oil-water emulsions, removing suspended solids, and meeting stringent discharge or reinjection standards.
Our Solution
- Demulsification: Cationic PAM or specialty demulsifier
- Coagulation: PAC (industrial grade, high basicity) at 100-300 mg/L
- Flocculation: CPAM at 2-5 mg/L
- Polishing: Activated carbon for dissolved hydrocarbons
6. Paper & Pulp Industry
Our Solution
- White Water Treatment: PAC (150-300 mg/L) + APAM (2-4 mg/L)
- Effluent Treatment: PAFC for combined color + COD removal
- Sludge Dewatering: CPAM high cationic charge
7. Food & Beverage Processing
Our Solution
- Primary Treatment: PAC drinking water grade (iron-free formulation)
- DAF System: Cationic PAM (2-5 mg/L) for dissolved air flotation
- Process Water: Coconut shell activated carbon for purity
- Note: All chemicals must be food-grade certified
8. Swimming Pool & Aquatic Facilities
Our Solution
- Daily Disinfection: SDIC 60% granules or 200g TCCA tablets
- Shock Treatment: Calcium Hypochlorite 65-70%
- Coagulation: PAC or aluminum sulfate (5-15 mg/L)
- pH Control: pH Plus (soda ash) or pH Minus (sodium bisulfate)
