Understanding the Challenge: Industry-Specific Effluent Complexity

Effluent Treatment is not a one-size-fits-all solution. At Ventilair Engineers Pvt. Ltd. (VEPL), we treat Effluent Treatment Plant (ETP) design as a knowledge-intensive and case-specific discipline, guided by one critical parameter—wastewater quality.

Every industry, and often every plant within an industry, generates unique effluent characteristics. Therefore, before proposing any solution, VEPL mandates a comprehensive water quality analysis from an accredited laboratory. Only then can we determine the most suitable treatment pathway—physio-Chemical, Biological, or a Hybrid System.

Rice Mill Wastewater: A Special Case

Rice milling, especially when comparing raw rice to parboiled rice processing, produces widely varying wastewater in terms of:

• BOD (Biochemical Oxygen Demand)
• COD (Chemical Oxygen Demand)
• TSS (Total Suspended Solids)
• Oil & Grease
• Color, Odor, and pH variability

These differences necessitate a specialized approach to treatment.

VEPL’s Innovation: Hybrid Effluent Treatment Plant (H-ETP)

To address the complexities of rice mill effluent, VEPL has developed and implemented the Hybrid Effluent Treatment Plant (H-ETP) — a proprietary solution that combines:

• physio-Chemical Treatment
• Biological Treatment
• Optional advanced tertiary steps like Ozonation, Reed Bed Systems, and Polishing Units

This integrated multi-stage approach ensures high efficiency in reducing BOD, COD, and TSS levels, even under extreme conditions. We refer to this system as a Mix Biological & Combined Treatment Plant, or more commonly as our Biological ETP Hybrid Model.
