Abstract

"APRH- Tørkeprosees for slam med Aktiv Pellet Resirkulering. - beskriver en metode for tørking av bløtt og vått slam i et roterende tørkeapparat ved at pellets, biter av et fast stoff blandes inn i slammet ved innløpet til tørkeprosessen og forhindrer ved sin bevegelse at slammet under tørkingen danner en lirafase med høy viskositet som vanskeliggjør eller endog umuliggjør tørkeprosessen/ og at etter at tørkingen er avsluttet/ skilles pelletsene ut fra det tørkede slammet i en separator og resirkuleres kontinuerlig tilbake til innløpet av tørkeapparatet for gjenbruk i tørke- prosessen, og det tørkede slammet transporteres ut for videre behandling."APRH - Dry Process for Sludge with Active Pellet Recycling. - describes a method for drying soft and wet sludge in a rotary dryer by mixing pellets, bits of solid into the sludge at the inlet of the drying process and preventing its movement from sludge during drying, a high viscosity lira phase forms which makes it difficult or even impossible for the drying process / and that after the drying is completed the pellets are separated from the dried sludge in a separator and continuously recycled back to the inlet of the dryer for reuse in the drying process, and the dried sludge is transported out for further processing.
