No Secondary Settling Tank: A biofiltration-based approach where microorganisms remain inside the reactor without migrating out.

Minimal Electricity Usage: The system can function with little or no external power source.

Slow Microorganism Growth: Proprietary “inner breathing” process keeps biomass stable, reducing sludge production.

A WWTP concept ideal for rural areas or small communities needing robust treatment without heavy operational demands. Prototypes have shown significant promise in removing organic substances, nitrogen, and phosphorus, all at lower energy costs than conventional plants.

In many agglomerations above 10,000 PE, conventional stages alone aren’t enough for advanced nutrient limits. Smaller facilities may also need final polishing when their secondary processes underperform.

Biofilm Reactors & Irrigated Filters: This technology uses rotating drums or structured filler with high porosity and a large surface area, increasing contact between microorganisms and wastewater.

Reduced Chemical Dependency: We develop solutions that maximize BOD, solids, and nutrient removal without relying on additional reagents.

Adaptable for Scale: Systems are suitable for both mid-range and large WWTPs, ensuring consistent phosphorus and nitrogen reduction.

Our tertiary systems achieve high pollutant removal rates — notably for total nitrogen, total phosphorus, BOD, and suspended solids—while minimizing chemical usage, operational costs, and environmental impact.

Biological nutrient removal can stall if the wastewater lacks a sufficient ratio of readily biodegradable organics. This shortfall leaves certain bacteria unable to consume nitrogen and phosphorus effectively.

Dedicated Hydrolysis Unit: Primary sludge is recirculated and held for optimal time, encouraging microbial breakdown into simpler organic compounds.

Enhanced BOD/N/P Ratio: Hydrolysis increases the availability of easily biodegradable carbon, boosting denitrification and phosphorus uptake in the main bioreactor.

Process Integration: The hydrolysis step can be retrofitted into existing treatment lines, immediately improving nutrient removal without major facility overhauls.

Improved nitrogen and phosphorus removal, more stable biological processes, and potentially lower overall sludge production. Targets can include effluent pollutants of ≤0.5 mg/l Pb and ≤10 mg/l Nb in some designs, depending on local regulations.
