    摘要： Various examples related to electrokinetic dewatering (EKD) of suspensions such as, e.g., phosphatic clay suspensions are provided. In one example, a system for continuous EKD includes cake dewatering unit having a lower conveying belt extending across a dewatering chamber; an upper conveying belt extending across at least a portion of the dewatering chamber; and a sludge inlet configured to supply a sludge suspension on the first end of the lower conveying belt. The conveying belts can extend across the dewatering chamber at an angle. Rotation of the conveying belts draws the sludge suspension through an electric field where the sludge suspension is dewatered. The electric field can be established between an upper anode and a lower cathode. The upper and lower conveying belts can include the anode and cathode. A suspension thickening unit can provide a thickened sludge suspension the cake dewatering unit for enhanced dewatering.

    摘要： The present invention is an improved washout pan and method for using it that automatically induces stress at the materials-pan surface interface to induce release of cement-containing materials by the nature of the construction of the washout pan and its response to being moved from a horizontal to a vertical position. The composition of the invention washout pan is critical to the objects of the invention, in that it is preferably formed of polypropylene in a rotomolding process as a single piece with a general overall shape of a box with a slurry body capacity of from 100 to 300 gallons.

    摘要： Technique to provide an abrasive regeneration method which, from a used abrasive slurry, can recover an abrasive by an efficient method and can thereafter obtain a high-purity regenerated abrasive by a simple method. This abrasive regeneration method uses an abrasive comprising at least one type of abrasive selected from diamond, boron nitride, silicon carbide, alumina, alumina zirconia and zirconium oxide. The abrasive regeneration involves a slurry recovery step (A) for recovering an abrasive slurry discharged from a polishing machine, a separation and concentration step (B) for adding an alkaline earth metal salt as an inorganic salt to the recovered abrasive slurry to aggregate the abrasive, and separating and concentrating the abrasive from a mother liquor, and an abrasive recovery step (C) for recovering the separated and concentrated abrasive.

    摘要： An environmental waste water filtering system, including a bucket, the inside of which tapers into a funnel portion that leads to a strainer. The funnel has an exit tube that extends 3 inches below the bucket wall and may be inserted into a drain such as a toilet drain pipe. The inside of the bucket and funnel portion forms a fluid debris chamber. When fluid containing particulate matter is poured into the fluid debris chamber, the particulate matter is removed from the fluid portion as the fluid passes through the strainer and then into the toilet drain pipe. Once all fluid drains from the fluid debris chamber, the captured debris may be poured into a trash bag and disposed of. Optionally, a disposable straining filter bag may be positioned in the fluid debris chamber so that even finer particulate matter is removed from the fluid for disposal with the bag.
