Drying technologies for sewage sludge andritz
Fluidized bed dryers for drying dewatered sewage sludge operate in a closed inert gas loop. The entire heat required to evapo rate the water is fed to the dryer via heat exchangers, i.e. without any direct contact between the heat transfer medium and the product. The dewatered sewage sludge is pumped directly to the fluidized bed dryer
Biosolids/Sludge Dryer KomlineSanderson
The KS Paddle Sludge Dryer is indirectly heated using steam or circulated thermal fluid (hot oil). Highenergy efficiencies and low offgas volumes are characteristics of a KS Drying System. The KS Paddle Sludge Dryer is an indirect heat transfer device that utilizes mechanical agitation to enhance contact with the product being dried.
VOMM Sludge Dryer: Technology DRYCAKE
The particle has a spiral movement (as the combination between a rotary motion and a linear one) and the drying treatment requires few dozen seconds. As a consequence there is a very low amount of sludge inside the dryer instant per instant (50150 kg approx. depending on the size of the plant).

DRYING & COOLING SOLUTIONS FEECO
INDIRECT ROTARY DRYERS When direct drying is not an option, FEECO offers stateoftheart indirect dryers to suit your drying needs. Indirect dryers are similar in design to direct dryers, but instead of using direct contact between the material and drying air to reduce moisture, the heating medium is kept separate from the material to avoid
What Fuel Sources can FEECO''s Rotary Dryers and Kilns Work
Electricity is an option for indirect rotary dryers and indirect rotary kilns. Heating coils, or rods, next to the drum''s shell radiate heat through the shell. An advantage to electricity, compared to other fuel sources, is that is no emissions or exhaust gases are produced, and thus no gas treatment or exhaust system is needed.

community and the sanitary sludge includes a good percentage of pulp from the local pulp and paper industry. An insulated rotary kiln sludge dryer 7 ft in diam and 40 ft long reduces the moisture in the sludge from 70 to 20 percent. The capacity of the unit is 6770 lbh of wet cake. The dryer
JMate® Continuous Dryer Evoqua Water Technologies
The JMate dryer achieves water removal rates from 45 lbs. to 190 lbs (20 KG to 86 KG) er hour in high volume appliions. While mechanical dewatering units can reduce sludge volume up to 20:1, a substantial amount of water still remains in the sludge cake material. The JMate dryer dehydrates the cake material to a dry granular form.
