TDS Reduction in ETP Water: A Breakthrough with Biotic’s Anaerobic Bio-Culture

Revolutionising Effluent Treatment with Sustainable Biotechnology

Introduction

In February 2025, Biotic Organic Solutions undertook a pilot trial at RKD Furnishing Private Limited, Panipat, to address a common but critical challenge in wastewater management — high Total Dissolved Solids (TDS) levels in ETP (Effluent Treatment Plant) outlet water. With water reuse and regulatory compliance becoming increasingly important, this project aimed to demonstrate the effectiveness of Biotic’s enzyme-based and anaerobic bio-culture solutions in significantly reducing TDS in industrial effluents. The trial was conducted under monitored conditions, with results documented to showcase the transformation — as seen in the accompanying media.

Key Challenges Faced

  • High initial TDS levels of 2600 mg/L, far above CPCB discharge standards.
  • Limited water reuse potential due to poor effluent quality.
  • Environmental compliance pressure on the client to reduce discharge pollution.
  • Scalability and cost-effectiveness of the solution for full-plant implementation.
  • Need for a sustainable, chemical-free. solution with minimal operational disruption

Biotic’s Organic Solution

To address the issue, Biotic used its proprietary anaerobic bio-culture technology in a trial lasting from 20th to 28th February 2025. The treatment involved:

  • A sealed, anaerobic container setup with 1000 litres of ETP inlet water
  • 500 gm of Biotic Sludge Treat, combined with molasses, urea, and DAP for nutrient support
  • Treatment duration of 5–7 days, allowing the culture to digest dissolved solids naturally
  • Seven samples taken during the trial to monitor the TDS drop at each phase

Key Biotic products used included:

  • Biotic Sludge Treat (Anaerobic Bio-Culture) – for natural microbial digestion of dissolved solids
  • Biotic's Enzyme Support Nutrients – to accelerate microbial activity in low-oxygen conditions

Results

The trial yielded remarkable outcomes, with TDS dropping from 2600 mg/L to just 400 mg/L — an 84% reduction over 8 days. The pH remained stable at 6.5 throughout the process. These results demonstrated that Biotic’s natural bio-culture solution is not only effective but also scalable and cost-efficient. The treated water showed significantly improved potential for reuse, compliant discharge, and environmental safety — making it a viable alternative to expensive and chemical-intensive methods.

As seen in the attached documentation and results, Biotic’s approach marks a new chapter in ETP water treatment — one that combines performance with sustainability.
