Waste Water Re-use Waste incineration generates a high humidity flue gas that also contains contaminants due to fuel. Flue gas condensing is a cost-efective and ecological way to increase the boiler`s district heat production. The condensate formed in flue gas condensation is with proper treatment usable to replace potable water as raw water. Due to the specific challenges of waste incineration, the Sofi process delivered does not discharge any water into the sewer.

With the Sofi process (MF and RO) approximately 75% of the condensate is gained as makeup water for district heating. Treated condensate is solids free low conductivity (< 150 µS/cm) water. Reverse osmosis uses high temperature membranes with a maximum operating temperature of 85 ° C. This, in addition to water recovery, allows for heat recovery without extra investment in heat exchangers.

District Heating Network
In CHP plant, even a small amount of very fine particle contamination, e.g. magnetite below 1 µm, lowers the efciency of the heat distribution system and may result to uncertainty in measurement equipment. The solids are removed from side stream by automatic Sofi Filter unit.
