Biogas Dehumidification System (BDS)
Removal of water from biogas (BDS) The HRS Biogas Dehumidification System (BDS) removes water from biogas, protecting combined heat and power (CHP) engines from corrosion and cavitation. It can be supplied with a heat recovery section, increasing the overall efficiency of anaerobic digestion (AD) plants.

Concentration and Evaporation Systems
Evaporation is an efficient way of reducing the volume of effluents and wastes. Our evaporation systems raise effluent to its boiling point so that water is evaporated and then condensed, thus obtaining a concentrated end product and water. Forced recirculation uses a pump to send the product through the evaporator at high speeds, ensuring high…

Digestate Pasteurization for Renewable Energy (DPS)
The HRS DPS Digestate Pasteurization System has been specifically designed to meet the requirements of pasteurization in the anaerobic digestion and renewable energy sectors. The DPS is capable of pasteurizing digestate, feedstocks, sludge and similar materials and is suitable for both pre-and post-digestion pasteurization, allowing operators to maximize the efficiency of their overall process while…
Learn MoreConcentration of Environmental Waste for Renewable Energy (DCS)
The HRS Digestate Concentration System (DCS) reduces the volume of digestate from anaerobic digestion while increasing its value. In most situations, it is able to do this using surplus heat from the CHP engine or biogas boiler, which can be used up to four times by incorporating multi-effect evaporation technology.
