Ydro Process^®

Revolutionising Wastewater Treatment with Advanced Biological Science

The Ydro Process^® is a patented microbial system that eliminates excess sludge, improves effluent quality, and enhances biogas yield — all without the use of harmful chemicals.

What Is the Ydro Process^®?

The Ydro Process^® is an advanced biological treatment solution designed to optimise the performance of wastewater treatment plants through the power of resilient, naturally occurring bacteria.

Crucially, the Ydro Process^® does not replace indigenous bacteria — it balances with them, enhancing system biology.

Developed by Hydrotech Environmental and exclusively operated in the UK by Bio Environmental, the system introduces specially cultivated microbial cultures into wastewater streams.

These bacteria actively break down contaminants, reduce sludge accumulation, and significantly improve effluent quality — delivering cost savings, operational efficiency, and environmental resilience.

Core Benefits of the Ydro Process^®

Eliminates Excess Sludge: Drastically reduces the need for sludge handling, removal, and disposal — leading to major operational savings.
Enhances Effluent Quality: Enhances critical parameters including: Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Suspended Solids (SS), Total Nitrogen (TN), Total Phosphorus (TP)
Eliminates Fats, Oils, and Grease (FOG): Protects both treatment plants and sewer networks from system-blocking build-ups.

Reduces Nuisance Odours: Minimises hydrogen sulphide (H₂S) emissions and other odour-causing compounds.
Increases Biogas Yield & Quality: Supports better anaerobic digestion performance and energy recovery.
Reduces Micropollutants: Targets and reduces harmful trace contaminants that standard treatments may miss.
Safe for Humans & Ecosystems: Operates within safe ORP ranges, prevents phosphine release, and requires minimal use of metal salts or chemical dosing.

Sustainable. Smart. Proven.

The Ydro Process^® is already making an impact in wastewater treatment plants across Europe. By reducing phosphorus to below 1 mg/L and completely removing FOG and H₂S from systems — including anaerobic digesters — it offers an industry-leading, sustainable solution for modern treatment facilities.

Its integration requires minimal disruption and delivers long-term results that:
