Combined air-water wash would intermix the media and result in loss of media. The first operation is to allow the filter to drain down until the water lies a few centimetres above the top of the bed. Air is then introduced through the collector system at a rate of about 6.5–7.5 mm/s. The air breaks up the surface scum and dirt is loosened from the surface of the sand grains. This is followed by an upward flow of

1.The loss of fine sand and stone powder is small in sand washing process. The washed sand is of good gradation, the fineness modulus can easily meet the requirements of relevant standards. 2.The structure is simple. The bearing parts of impeller driving is isolated from the washing water and sand thus largely decreasing the failure rate.
