摘要： A cooking-oil filtration system and method for automated food-fryers with a solids-removing filter for cleaning cooking oil from the food-fryer which includes and involves an oil/air separator for receiving air-containing oil from the filter and then returning air-separated oil to the food-fryer. In certain highly preferred embodiments the oil/air separator includes a cylindrical inner wall and an inlet conduit configured for tangential entry and spiral flow of oil. In another embodiment, the oil/air separator is a surge tank having upper and lower tank upper portions and conduits facilitating the in-flow of air-containing oil and the gravity out-flow of air-separated oil to the food-fryer. In-flow is preferably driven by a pump upstream of the filter media.

摘要： An improved salt basket for dewatering solids, particularly salts resulting from evaporation of industrial wastewaters. The salt basket system includes a pressurizable vessel having a screen floor situated above a bottom liquid collection head, an inlet for the brine/solids slurry from which solids are to be separated and dried, an inlet for air, an inlet for steam (the latter two inlets may be combined, where convenient), an inlet for solids free feed, and a drain outlet (these two may be combined where convenient into a combination feed/drain connection). Preferably, an automated system for introducing feed brine and for removing the solids product is provided. For safety, a pivotally attached lower door has a hydraulic failsafe closure mechanism and locking safety latches to prevent the door from inadvertently opening. The process control design minimizes exposure of the salt basket interior to supersaturated solutions with precipitating solids therein, thus reducing scaling of the salt basket, by introducing feed brine rather than magma (crystal/concentrated liquor slurry) to the salt basket between crystal harvest cycles.
摘要翻译：用于脱水固体的改进的盐篮，特别是由工业废水蒸发产生的盐。盐篮系统包括可加压容器，其具有位于底部液体收集头上方的筛板底部，待分离和干燥固体的盐水/固体浆料的入口，空气入口，蒸汽入口（后者可以组合两个入口，方便），用于固体自由进料的入口和排水出口（这两个入口可以在方便的组合进料/排出连接中组合）。优选地，提供用于引入进料盐水并用于除去固体产物的自动化系统。为了安全起见，枢轴连接的下门具有液压故障保护闭合机构和锁定安全闩锁，以防止门不经意地打开。过程控制设计使盐篮内部暴露于过饱和溶液中，其中沉淀固体，从而通过在晶体收集循环之间将进料盐水而不是岩浆（晶体/浓缩液体浆料）引入盐篮来减少盐筐的结垢。

摘要： A method of operating a filter press, wherein filter material is fed into a filter chamber so as to form a filter cake between at least two sides of a flexible said filter medium. Filtrate is received from the filter chamber and the filter cake formed the filter chamber is discharged. Prior to discharging the filter cake, compression is applied on the filter cake formed within the filter chamber by providing compression fluid gas at a compression pressure exceeding a prevailing pressure within the filter chamber, directly on a side of the filter medium exterior to the filter chamber, so as to exert said compression pressure directly on said side of the filter medium, thereby causing the filter medium to yield against the filter cake.

摘要： The method of forming a filter cake from a slurry comprising the steps of feeding the slurry into a filter housing, wherein the filter housing includes a plurality of vertical filter elements; pressing the slurry into the filter housing against the filter elements resulting in i) a filtrate passing through the filter elements and exiting out an exhaust port of the filter housing; ii) forming a solid cake on the filter elements; feeding a wash liquid into the filter housing while draining out the slurry by opening the slurry drain valve; closing the slurry drain valve and then continually feeding wash liquid through the cake and into the filter tube of the filter housing; stopping the feed of wash liquid; introducing a gas into the filter housing and draining out the wash liquid by opening a bottom drain valve; stopping the gas flow and opening a drain to exit most of the gas and remaining wash liquid; opening the bottom cake discharge valve; and back pulsing by a gas to break and to release the filter cake from the filter elements of the filter housing.
