Types of Chemical Wastewater by Industry

Category	Typical Industries	Main Pollutants	Characteristics
Petrochemical Wastewater	Refineries, chemical complexes	Oils, organic compounds, high COD	Emulsified, deeply colored, hard to biodegrade
Pharmaceutical Wastewater	API plants, pharma factories	Antibiotics, intermediates, ammonia	Toxic, poor biodegradability
Dye and Pigment Wastewater	Dye synthesis & manufacturing	High colority, COD, sulfur compounds	Persistent color, stable molecules
Pulp & Paper Chemical Wastewater	Pulp mills	Lignin, fibers, suspended solids	High concentration, low biodegradability
Inorganic Chemical Wastewater	Fertilizer plants, metallurgy	Heavy metals, ammonia, phosphates	Corrosive, contains multiple ions

Recommended Chemicals for Treatment

Stage	Recommended Product	Function
1. Coagulation	Polyaluminum Chloride (PAC), Ferric Sulfate (FS), Polyferric Sulfate (PFS)	Removes TSS, lowers COD
2. Flocculation	Polyacrylamide (PAM)	Enhances sedimentation
3. Adsorption	Activated Carbon (Powder/Granular)	Removes color, odor & residual organics
4. COD/BOD Boost	Sodium Acetate, Glucose	Improves biodegradability & microbial growth
5. Ammonia/Fluoride Removal	PDADMAC, Aluminum Sulfate, ACH	Removes nitrogen, fluorides

Product Usage Guidance

Polyacrylamide (PAM): Dissolve at 0.1% concentration, stir for 30–60 minutes. Use after PAC or PFS.
Polyaluminum Chloride (PAC): Prepare a 10% solution. Add before PAM for optimal floc formation.
Polyferric Sulfate (PFS): 200–800 ppm dosage; ideal for high-COD, high-color wastewater.
Activated Carbon: Use in multi-layer filtration or adsorption columns for maximum efficiency.

Packaging & Storage

Product	Packaging	Storage Requirements
Polyacrylamide (PAM)	25kg woven bags/kraft bags	Store in dry, cool, ventilated places
Polyaluminum Chloride (PAC)	25kg woven bags	Keep sealed, avoid moisture
Polyferric Sulfate (PFS)	25kg woven bags or 1-ton bags	Protect from humidity
Activated Carbon	25-50kg bags	Keep in cool, dry areas
Sodium Acetate / Glucose / ACH	Customized	Avoid heat and humidity
