  • NAS - New Activated Sludge System

    NAS - New Activated Sludge System

    Anammox in active sludge: NAS (New Activated Sludge) represents a unique active sludge system in which anammox bacteria constitute a part of the biomass. These micro-organisms ensure a very effective removal of the nitrogen during aerobic purification.

  • AMFER - Removal of Ammonia from Digestate & Wastewater

    AMFER - Removal of Ammonia from Digestate & Wastewater

    Nitrogen removal from ammonia containing water / sludge / digestate and the production of (artificial) fertiliser. During the fermentation of manure and other organic substrates the organic nitrogen present is largely transformed into ammonia (NH4) nitrogen. The high nitrogen content constitutes a limiting factor for field application of the digestate (as a result of European nitrate directive). Current digestate treatment is making use of biological...

  • ANPHOS - Phosphate Recovery from Wastewater

    ANPHOS - Phosphate Recovery from Wastewater

    Application: In order to remove phosphates from waste waters or digestate in an environmentally friendly manner the ANPHOS® process can be applied. During anaerobic waste water purification the phosphate present is largely converted into ortho-phosphate, whereas the nitrogen is converted into ammonia (NH4-N). In case of aerobic pre-purification orthophosphate is formed as well with potassium as counter-ion.

  • RO-Recycle / MemPhos - Reversed Osmosis Treatment and Desalination of Waste Water

    RO-Recycle / MemPhos - Reversed Osmosis Treatment and Desalination of Waste Water

    Application: By means of the newly developed RO-Recycle process it is possible to improve the quality of the effluent of biological water purification systems to fresh water for boiler feed or cooling towers or to process water. This RO (reversed osmosis) technology is capable of processing up to 70 % of the total effluent and generate these water qualities. Current state of the art RO systems are capable of phosphate removal such that chemical...

  • Anaerobic Granular Sludge - Active Biomass for Inocculation and Kick Start UASB

    Anaerobic Granular Sludge - Active Biomass for Inocculation and Kick Start UASB

    Active biomass for inocculation and kick start UASB. Anaerobic wastewater treatment is frequently applied in several industrial sectors. The granular sludge plays a vital role within this technology. In this way waste water containing levels of organics (COD) is purified effectively. Anaerobic biomass present in the reactor transforms the organic matter into biogas and water. The anaerobic reactors are designed to stimulate the formation of granular...

  • Thermophilic Digestion - Efficient Digestion of Organic Matter in Waste Streams

    Thermophilic Digestion - Efficient Digestion of Organic Matter in Waste Streams

    Application: Fermentation represents a natural and anaerobic dissimilation process during which organic biomass is transformed. Certain bacterial strains are capable of converting organic material mainly into methane (CH4), carbon dioxide (C02) and water. The efficiency of the conversion is determined by the system and the nature of the substrate. This anaerobic digestion process takes place in two different ranges on the temperature scale, i.e. from...

  • Colsen - Thermophilic Sludge Digestion System

    Colsen - Thermophilic Sludge Digestion System

    The treatment of WWTP sludge represents a considerable cost for a sewage purification plant. In case the sludge amount is lowered the associated costs can be reduced. An efficient way for the reduction of the sludge amount is thermophilic sludge digestion. When compared with conventional mesophilic digestion thermophilic conditions take care of degradation of an much higher amount of the organic fraction (10-25% more conversion). The (additional)...

  • DIGESTMIX - Efficient Mixing and Heating System for Digesters

    DIGESTMIX - Efficient Mixing and Heating System for Digesters

    The unique DIGESTMIX system is capable of mixing and heating the content of a digester at minimum operating (energy and maintenance) costs. This mixing b heating device facilitates a stable temperature, intensive mixing and abatement and prevention of floating layers and scum in the reactor. The DIGESTMIX can also be delivered in mixing mode only. This mixing and heating device is situated outside the reactor and allows you to operate a digester...

  • NutriDox - Balanced Broth for Optimal Microbial Activity

    NutriDox - Balanced Broth for Optimal Microbial Activity

    Micro-organisms play a key role in nature and mankind has learned to deploy their enormous variety of biochemical capabilities. Biological process steps have therefore become more and more common in industrial applications. The well being of the biomass has often become a critical factor in a sequence of process steps. The last decennia Colsen has developed a number of biological processes for industrial and communal water purification, for bio-energy...
