Complex Wastewater. Smarter Biological Engineering.
Industries like textile, food, tannery, and recycling are challenged by diverse contaminants - high COD/BOD, TDS, oils, grease, color, and fluctuating loads. Most conventional ETP solutions rely on chemical treatment, which often leads to high OPEX, sludge generation, and inefficiencies during peak loads.
Our Solution: Biological-First ETPs
WTT International designs ETPs that excel through a biological-first philosophy. At the heart of our process is an engineered microbial ecosystem that digests complex contaminants naturally - significantly reducing chemical dosing and operational costs. Combined with robust clarification, membrane innovation, and compact automation, our systems enable:
- Highly stable treatment under variable loads
- Reduced sludge volume and disposal frequency
- Environmentally safe and regulation-compliant output
- Scalability for Zero Liquid Discharge (ZLD) execution
All treatment systems are manufactured and implemented by WTT’s in-house engineering and commissioning team.

Our Treatment Highlights
Our induced draft cooling towers are a foundational step in protecting biological efficiency. They operate by reducing influent temperature to optimal biological ranges, preventing thermal shock and allowing aerobic microbes to thrive. Their modular design ensures consistent heat dissipation and air draft flow, while integrated automation allows continuous performance monitoring.
- Lowers incoming water temperature to biological-safe levels.
- Increases dissolved oxygen (DO), enhancing aerobic digestion.
- Prevents damage to microbial colonies in biological stages.
- Supports overall stability, especially in tropical or high-load facilities.
Our biological stage is the engine of pollutant degradation. Designed around extended aeration principles, it uses engineered blower systems to supply optimum oxygen levels. Combined with smart microbial seeding, this step effectively handles high-COD/BOD wastewater including complex compounds like starches, fats, proteins, and dyes.
- Integrates blower design (twin-lobe or screw) for high efficiency.
- Custom microbial consortia matched to industry-specific loads.
- Offers robust degradation with minimal chemical dependency.
- Configurable retention time and tank geometry to meet space constraints.
MBR merges biological degradation and advanced membrane separation in a single, compact system. It is key to achieving clear, odorless, pathogen-free water suitable for reuse in industrial processes.
