Biological Wastewater Treatment for Industrial Wastewater with High Organic Loads
The OKO-bio is a high-performance system for aerobic biological treatment of industrial wastewater. Using proven trickling filter technology, organic compounds are biologically degraded, significantly reducing key wastewater parameters such as COD (Chemical Oxygen Demand) and BOD₅ (Biochemical Oxygen Demand).
The system is particularly suitable for industrial wastewater with high organic loads. It helps companies meet discharge limits, reduce the load on downstream treatment stages and lower operating costs over the long term.

Aerobic Biological Wastewater Treatment
Aerobic biological wastewater treatment uses naturally occurring microorganisms to break down dissolved organic matter in wastewater. The microorganisms require oxygen, which is continuously supplied to support the biological treatment process.
During biological treatment, organic compounds are converted into stable end products such as carbon dioxide, water and biomass. This significantly reduces wastewater loads and helps ensure compliance with applicable discharge requirements.
Biological treatment is a particularly sustainable and economical solution for industrial wastewater with high organic loads and is successfully used across a wide range of industries.
Trickling Filter Technology for Efficient Biological Treatment
The core of the OKO-bio is its proven trickling filter technology. Wastewater is evenly distributed over highly effective filter media using a specially designed nozzle system.
Microorganisms colonise the surface of the filter media and form an active biological biofilm. As the wastewater flows through the trickling filter, the microorganisms continuously degrade the organic compounds it contains.
The high specific surface area of the filter media provides favourable conditions for the biological treatment process. At the same time, targeted aeration of the trickling filter ensures a continuous supply of oxygen, supporting stable and energy-efficient system operation.
Trickling filter technology is characterised by high operational reliability, low energy consumption and robust performance under fluctuating organic loads.
