Nowadays, many Danish purification plants use the sand washer from Stjernholm as a fixed installation. Therefore, we are able to document very good results, e.g. up to 95% dry matter and an ignition loss of less than 1%.
The sand washer from Stjernholm is characterised by effective washing, leaving a minimal amount of organic material in the sand and a minimum of sand particles in the reject water. Such a high level of efficiency significantly reduces costs related to disposal and transport.
All our sand washers are prepared for installation in complete sand washing facilities, including receiving station, drum screen, pre-drainer etc. for the treatment of external sand from sand washing facilities.
