ETP Food and Beverage

At Hydro Water Industries, we provide a comprehensive range of Effluent Treatment Plants (ETPs) specifically tailored for the food and beverage industry. Wastewater generated by this sector typically contains a high load of hazardous contaminants such as:

  • Suspended and total solids

  • BOD (Biological Oxygen Demand)

  • COD (Chemical Oxygen Demand)

  • Edible oils and grease

  • Sugar and starch residues

  • Preservatives, colours, and organic compounds

Untreated, this wastewater poses a serious threat to the environment and public health. Therefore, government regulations mandate its proper treatment before discharge. Our state-of-the-art ETP systems ensure full compliance with PCB (Pollution Control Board) norms, and facilitate safe reuse and eco-friendly discharge.


ETP for Food and Beverage Industry

As a leading ETP manufacturer based in Delhi NCR, Hydro Water Industries brings nearly a decade of experience and excellence to the field of effluent treatment. We offer various system configurations—manual, semi-automatic, and fully automatic—and employ multiple treatment methods, including:

  • Physical Treatment

  • Chemical Treatment

  • Biological Treatment

Our standard ETPs generally follow four levels of treatment:

1. Preliminary Treatment

Larger solids are removed through coarse screening, grit chambers, and crushers to break down solid waste. The goal is to prepare the effluent for further processing.

2. Primary Treatment

This stage includes gross filtration to remove 50–60% of suspended solids, including oils, fats, and nutrients like nitrogen and phosphorus bound to these solids.

3. Secondary Treatment

Involves aerobic and anaerobic biological processes such as activated sludge treatment, which uses microorganisms in an oxygen-rich environment to decompose biodegradable material.

4. Tertiary (Final) Treatment

Advanced treatment technologies are used to remove remaining contaminants. This stage may include:

  • Chlorination

  • UV disinfection

  • Ozonation

After this step, the water is free of all harmful pollutants and safe for discharge or reuse.

Note: As BOD load is evenly distributed in the daily discharge, no separate BOD removal is suggested.


Treatment Process Flow

  • Effluent from all sources is collected in an underground equalization tank.

  • It is screened using a bar screen and passes through an oil and grease trap.

  • Air agitation ensures homogeneity.

  • Effluent is pumped into a flash mixer, where coagulants and chemicals are dosed using automatic dosing pumps.

  • Mixed water flows into a clari-flocculator.

  • Flocculants are added to form flocs which settle in a tube settler (inclined PVC tubes at 60°).

  • Sludge is dewatered using sludge drying beds or filter press, and the resulting sludge cakes are sent to PCB-authorized landfill.

  • Clarified water is passed to biological treatment, followed by:

    • Dual Media Filter (DMF) for TSS removal

    • Activated Carbon Filter (ACF) for odor and color removal

  • Final water is collected in treated water holding tanks for safe discharge or reuse.
