Sludge waste disposal is the need of many organizations producing these wastes being in line with the norms of the regulatory bodies. Disposal agencies charge in Kgs and pounds as per the local standards. However, approximately 80% of these sludge is water so indirectly you are paying to pick up water which can be dried to save sludge hauling and disposal costs. Handling and storage of dried sludge are easy and all further disposal is easy. The dried product produced out of drying sludge can be used as fertilizer and/or biofuel in some cases.
Sludge Drying systems designed and manufactured by Kerone are designed to fit for small, medium, and large quantity sludge generators. Drying systems can fit under the filter press for direct loading or can be located on remote locations within the plant. At the time of the thermal drying of sludge, almost all water is evaporated, including surface, capillary, and cell water. Supply of heat is needed, if possible from mutual power and heat generation systems. A great portion of the drying heat is recovered from the exhaust and re-circulated.
The sludge is dried by the heated liner of our unit while it is broken-up and circulated by our spiral blade system.
The dryer liner uses indirect heat sources from steam, electric strips, or gas fire. Our preheated airflow system draws the moisture off the top of the internal dryer and out through our wet scrubber system. After typically 4-6 hours of drying time (depending upon the type and wetness of the sludge) the dried material is removed by simply opening our discharge panel underneath our units for gravity discharge into a container.
Another option is to include a conveyor auger to move the sludge to an elevated container. You have options depending upon your particular space requirements or restrictions.Features and advantages offered by sludge dryers:
