Enhanced sludge dewatering by dual polyelectrolytes conditioning

Sludge dewatering by dual polyelectrolytes conditioning was investigated in this study. Single polyelectrolyte is utilized in sludge conditioning conventionally, in which charge neutralization and bridging are involved in the reactions. In the current study, both cationic and non-ionic polyelectrolytes were utilized simultaneously in the conditioning. Waste activated sludge was sampled from a synthetic fiber plant, and used in the experiment. Capillary suction time (CST), specific resistance to filtration (SRF), and settling rate were used to evaluate the sludge dewatering behaviors. Zeta potentials were also measured. Sludge dewatering behaviors resulting from single and dual polyelectrolytes conditioning were compared. It was found that sludge conditioned with dual polyelectrolytes performed better in fine particle capture and in the formation of larger flocs that resulted in a better dewaterability and less chance of overdosing. The dosing sequence in dual polyelectrolytes also affected the sludge dewaterability. Reaction mechanisms in dual polyelectrolyte conditioning were proposed based on enhanced flocculation of sludge particles.     

Analysis of output voltage on a planar insulating core transformer

Output voltage is an important performance characteristic of planar insulating core transformer (PICT).In PICT magnetic cores are insulated from their neighboring magnetic cores by solid insulating materials.Solid insulating materials can increase leakage flux.This results in a low generated voltage in secondary coils,especially on the upper stages.Connecting flux compensation capacitors to secondary coils can compensate the flux loss.Design equations to calculate the flux compensation capacitors value and relevant simulation by CST and Protel software were presented.Simulation results of an actual PICT showed that output voltage increased by 19% after being connected to flux compensation capacitors and the voltage on every stage was equally distributed.Results of simulation were consistent with the following experimental test,which revealed that flux compensation capacitors were effective.
