The influence of precipitation centrifugation on the dewatering efficiency of clay-salt sludges. The moisture content of the resulting sludge was found to be decreased in proportion to the increase of the centrifuge separation factor. The addition of polyacrylamide solution to the suspension allows to reduce the moisture content of centrifuged sludge by 3...4%.
