The highly-efficient Exerger FVE reduces the overall cost of the evaporating unit compared to standard evaporators. It is worth noting that Reverse Osmosis (RO) doesn’t provide a solution for the final goal – the wastewater disposal (RO performs only the wastewater concentration). RO is not quite reliable under the conditions of high salt concentration and variable wastewater composition. It requires more frequent acid cleaning and creates extra wastewater.
