SLUDGE THREE-DIMENSIONAL ELECTROOSMOSIS DRAINAGE REINFORCEMENT METHOD BASED ON ELECTRIC GEOTEXTILE COMPLEX

Disclosed is a sludge three-dimensional electroosmosis drainage reinforcing method based on a novel electric geotextile complex, and belongs to the field of soft soil foundation reinforcement. A novel electric geotextile complex is adopted, and a designed multidirectional three-dimensional continuous electroosmosis drainage method is adopted to perform rapid drainage reinforcement treatment on sludge, wherein the electric geotextile complex is prepared by combining fibers and conductive materials with a flexible drainage plate and has the effects of electric conductive, drainage, corrosion resistance and reinforcement. The proposed drainage method can realize the electroosmotic drainage in vertical and horizontal directions. Through layer by layer electroosmosis from bottom to top, the consolidation drainage effect of sludge in the lower layer can be enhanced by the increasing loading pressure from the upper sludge. After the vertical electroosmosis is completed, the method of exchange electrode is used to conduct horizontal electroosmosis in opposite direction.

PRODUCTION OF CONCENTRATED SPENT DIALYSATE

A concentrated spent dialysate is produced for by reducing electrolytes in a spent dialysate by electrodialysis and de-watering the spent dialysate by a forward osmosis operation.

A hemodialysis treatment apparatus has an ultrafiltration unit for exchange of solutes of a patient's blood plasma and a dialysate, resulting in a stream of cleaned blood for returning to the patient and a stream of spent dialysate. An electrodialysis device reduces electrolytes in the spent dialysate. A forward osmosis unit with a membrane having a feed side and a draw side that is allows only water to permeate. A stream of spent dialysate from the ultrafiltration unit is in fluid communication with the feed side and a stream of concentrated dialysate is in fluid communication with the draw side. A stream of dialysate results. Blood plasma is pumped from the patient to the ultrafiltration unit.

SYSTEM AND METHOD FOR SEPARATING SOLVENT FROM A FLUID
20230144024 · 2023-05-11 ·

An electrochemical system has a first reservoir receiving a feed stream. The feed stream includes a solvent and a solute different than the salt. A second reservoir receives a brine stream with a higher salt concentration higher than the feed stream. Electrodes contact a loop of redox- active electrolyte material causing reversible redox reactions. The reactions cause the loop to accept a first ion from the salt in the first reservoir and drive a second ion into the brine stream in the second reservoir. Three ionic exchange membranes of alternating type define the first and second reservoirs. A concentrate stream is output from the first reservoir, the concentrate stream having a second solute concentration greater than the first solute concentration.
