Ventilair Engineers Pvt. Ltd.
Advanced Effluent Treatment Plant (ETP) for Chocolate Manufacturing Industry
The chocolate manufacturing industry generates wastewater with extremely high concentrations of biodegradable organic matter, dissolved sugars, cocoa solids, milk residues, emulsifiers, fats, oils, grease (FOG), cleaning chemicals, and suspended solids. Due to the presence of these contaminants, untreated chocolate wastewater exhibits very high BOD, COD, TSS, and Oil & Grease, making conventional treatment systems ineffective without proper process engineering.
Ventilair Engineers Pvt. Ltd. specializes in the design, manufacturing, installation, commissioning, and optimization of high-performance Chocolate Industry Effluent Treatment Plants (ETP) that ensure regulatory compliance, operational reliability, and maximum treatment efficiency.
Our systems are engineered to consistently achieve discharge standards prescribed by CPCB/SPCB while minimizing operating costs and maximizing water recovery.
Why Chocolate Industry Needs a Specialized ETP?
Chocolate production wastewater typically contains:
✔ Cocoa Powder Residues
✔ Sugar & Glucose Syrups
✔ Milk Solids & Dairy Components
✔ Vegetable Oils & Cocoa Butter
✔ Emulsifiers & Stabilizers
✔ CIP (Clean-In-Place) Chemicals
✔ High Organic Load Wastewater
✔ Process Wash Water Contaminants
Common Effluent Characteristics
Parameter Typical Range
pH 5.5 – 9.0
BOD 3,000 – 15,000 mg/L
COD 6,000 – 30,000 mg/L
TSS 500 – 5,000 mg/L
Oil & Grease 100 – 1,000 mg/L
TDS Site Specific
Such wastewater requires a scientifically designed treatment system incorporating physical, chemical, and biological treatment processes.
