The freshness of the sludge: the colloidal nature of the sludge will increase with its level of fermentation (septic sludge). The origin of the wastewater: a dairy or brewery origin will increase the colloidal nature of the sludge. The sludge return: a badly controlled return of the sludge will increase its colloidal nature.

clay dryer, clay drying equipment

The drying process is described as this: wet clay is fed into rotary dryer at cocurrent with hot gases. As the cylinder rotates, clay is lifted and distributed by the flights. Hot gases pass by and through clay at reasonable rate. High efficient heat transfer is completed during this stage. Inside clay dryer, the temperature is about 400600°C.

Technology and innovative options related to sludge .

Sludge production cannot be avoided, and as effluent quality standards are tightened to reduce nutrient emissions, sludge production will inevitably increase. Similarly, sludge production cannot be minimised although there are technologies which reduce the mass of sludge for disposal (dewatering, drying, volatile solids destruction). The
