  • Apparatus for the treatment of filter sludge consisting predominantly of diatomite and method of operating same
    Patent number: 5145492
    Abstract: An apparatus for the treatment of diatomite, especially in a filtration sludge for disposal in a landfill or reuse as a filtration aid, having a flow dryer followed by a cyclone and filter separator. The dry product is then subjected to treatment in a high-temperature treatment chamber and a cyclonic separator separates 80% of the solids from the gas. These solids are quenched and then cooled. The balance of the solids in the gas stream are fed as the drying gas to the flow through dryer after water injection cooling to reduce the temperature of the hot gas to a temperature at below that which organics are volatilized in the dryer.
