Monitoring of a sludge dewatering equipment by image classification
Belt filter presses represent an economical means to dewater the residual sludge generated in wastewater treatment plants. In order to assure maximal water removal, the raw sludge is mixed with a chemical conditioner prior to being fed into the belt filter press. When the conditioner is properly dosed, the sludge acquires a coarse texture, with space between flocs. This information was exploite...
متن کاملSludge Dewatering with Cyclodextrins: a New Cost-effective Approach
Polymers are typically added to flocculate sludge during wastewater treatment. We have found that cyclodextrins (CDs) boost the performance of these polymers by increasing the cake solids and drainage rates of beltor screw-pressed biological or primary sludge. These benefits are obtained at very low CD dosage. CDs also decrease the specific resistance to filtration and increase the capture rate...

Sludge Dewatering by Impulse Drying
An innovative and energy efficient sludge dewatering technology has been developed. The technology, impulse drying, involves briefly contacting the sludge under pressure with a heated surface. A unique feature of impulse drying is that the majority of moisture removal occurs as lipid water. A pilotand laboratory-scale demonstration was performed on low ash primary paper mill sludge. The pilot-s...
متن کاملSludge Dewatering and Mineralization in Sludge Treatment Reed Beds
Sludge Treatment Reed Beds (STRBs) are widely used in Northern Europe to dewater and mineralize surplus sludge from activated sludge systems used to treat urban domestic sewage. STRBs are low-technology, energy-efficient, and do not require addition of chemicals. They dewater and stabilize the sludge and produce a final product that can be safely used as a fertilizer for agricultural crops. Lon...
