Ground Water

Ground Water

Treatment is focusing upon a combination of efficient aeration and continuous (bio)filtration. Main components to be removed are iron, manganese and ammonia. Both physical-chemical and biological processes are applied to meet drinking water quality levels.

Ground Water

Compact Treatment

Classic groundwater treatment schemes consisting of aeration/degasification and (moving bed) filtration or anaerobic N/F or R/O membrane filtration. A compact system set-up.

Cost Effective

Modular system and cost effective set-up in a wide range of capacities. High uptimes and low installed power requirements. No backwash pumps, backwash storage facilities by using moving bed filtration.

High Performance

Stable performances for removal of iron, manganese and ammonia. Both physical-chemical and biological conversion processes in one reactor.  

Process Combinations

 Typically groundwater used for drinking water production is treated to remove traces of iron, manganese and/or ammonia. After appropriate conditioning these components are effectively removed by physical-chemical processes and biological conversion.

In contaminated groundwater sources, e.g. by the presence of hydrocarbons, aerated moving bed filtration proves to be a reliable and cost effective solution. 

Biological Conversion

Remediation of groundwater resources contaminated with various biodegradable components are efficiently treated by aerated moving bed continuous filters. Both air and oxygen is used to create oxic environments inside the filter bed. As a result biomass is growing on top of the filter media, and biological conversion of biodegradable components is promoted. 

Moving bed (bio) filtration is a mode of granular media filtration based upon uninterrupted filter operation. It enhances the stable and reliable removal efficiencies.

Our Unique Selling Points

Combined Process

Efficient oxygen uptake by hydraulic aeration processes, conditioning to release carbon dioxide and/or methane gas. Consequential physical-chemical removal of iron and biological conversion of manganese and/or ammonia will result in final effluent qualities, meeting drinking water guidelines. 

Contaminated Water Treatment

In contaminated groundwater sites biological conversion of organic components proves to be effective in removing harmful compounds, such as hydrocarbons. Both poly-cyclic and mono-cyclic hydrocarbons are efficiently converted by the cultivated biomass in a moving bed aerated biofilter. 


We are happy to collaborate with our clients to meet their objectives. And we highly appreciate their feedback!
