Greenlan disc film dryer uses steam as energy with disc structure to dry and crystallize wastewater "in one step" and eventually leaving trace dry solid waste with moisture to reach 1%. It's really efficient and stable. It can obtain clear, higher quality distilled water with COD reduced by 99%. The dry solid waste is automatically discharged to achieve full automatic operation. It's widely used high COD wastewater treatment, high salt wastewater treatment and other refractory wastewater treatment, such as landfill leachate, biological fermentation wastewater, etc. This machine is very easy to operate. Turn on for 10 seconds, the salt will come out.
