ETP for Sugar Mill Industry
The sugar industry is highly water-intensive, utilizing large volumes of freshwater across various stages of processing. Consequently, sugar mills generate significant quantities of effluent that require safe, efficient, and compliant treatment to prevent environmental contamination and health hazards.
At Hydro Water Industries, we specialize in the design, manufacture, and implementation of advanced Effluent Treatment Plants (ETPs) specifically engineered for the sugar industry. Our solutions enable mills to meet regulatory requirements, reduce water consumption, and support sustainable practices.
Why ETP is Essential in the Sugar Industry
Freshwater is essential in sugar mills for:
Raw material cleaning and separation
Fiber swelling and transportation
Juice extraction and crystallization
Equipment washing and general utilities
This leads to the discharge of effluent containing:
Suspended solids
Organic matter (bagasse, molasses)
Nutrients like phosphorus and nitrogen
Oil and grease
High BOD and COD
Trace hazardous chemicals
If untreated, these contaminants can damage local ecosystems, degrade soil quality, and pollute groundwater.
Wastewater Characteristics – Before and After Treatment
| SN | Parameter | Before Treatment | After Treatment |
|---|---|---|---|
| 1 | Temperature | 25°C – 35°C | ≤ 5°C above ambient |
| 2 | Colour | Light yellowish | Colourless |
| 3 | Odour | Present (light) | Nil |
| 4 | pH | Variable | 6.5 to 8 |
| 5 | TSS | Present | Reduced to PCB limits |
| 6 | Oil and Grease | Present | Within permissible limits |
| 7 | BOD | Present | Reduced to permissible limits |
| 8 | COD | Present | ≤ 150 mg/l (as per PCB) |
Note: As the BOD load is evenly distributed in daily discharge, separate BOD removal is not required.
ETP Process Flow Description
Equalization & Pretreatment
Effluent is collected in an underground tank from all processing sections
Bar screen removes coarse particles
Oil and grease trap separates floating contaminants
Air agitation ensures uniform mixing in the equalization tank
Chemical Dosing & Coagulation
Effluent is pumped to a flash mixer
Coagulants and flocculants are dosed using auto dosing pumps
Agitated effluent moves to a clari-flocculator
Fine particles form sludge flocs that settle through inclined tube settlers (TubePac media)
Sludge Handling & Dewatering
Sludge is transferred to sludge drying beds or filter press
Dewatered sludge is formed into cakes
Solids are disposed at PCB-approved landfill or designated sites
Filtrate is recycled to the equalization tank
Filtration & Polishing
Treated water is stored in a holding tank
Passed through Dual Media Filter (DMF) to reduce TSS
Followed by Activated Carbon Filter (ACF) to remove color, odor, and residual organics
Optional chlorine dosing ensures microbial safety
Advanced Options (Optional)
Reverse Osmosis (RO) for high-purity water recovery
Vacuum evaporation for handling RO reject
Recovered water reused in process or for horticulture
