In such aspects, the LCMMS is an all in one solution for monitoring and maintaining the liquid within the container. The LCMMS is configured to be an external system that can couple to various storage containers via various access ports. The LCMMS is configured to automatically monitor and maintain the liquid contained within the container. In an aspect, the LCMMS can be remotely controlled, as well as provide reporting to various users.

A fuel filter insert for a fuel filter including: a pre-filter element having a upper and lower end plate, the end plates arranged on opposing ends of filter medium of the pre-filter element; a main filter element having upper and lower end plates, the end plates arranged on opposing ends of filter medium of the main filter element; wherein the pre-filter element and the main filter element as arranged one above the other in a direction of a longitudinal axis of the fuel filter insert; wherein at least one of the filter elements is through-flowable from the outside to the inside by fuel in a radial direction relative to the longitudinal axis; and a flow channel for the fuel pre-filtered by the pre-filter element; wherein the flow channel is arranged to extend in the axial direction between the pre-filter element and the main filter element.

A water separating device of a filter element for separating water from a liquid hydrocarbon has a coalescing medium in the from of a hollow body and designed to coalesce water droplets of the liquid hydrocarbon passing through the coalescing medium in a flow direction of the liquid hydrocarbon. A hydrophobic separating medium in the form of a hollow body and permeable for the liquid hydrocarbon is provided. The hydrophobic separating medium is arranged in a flow direction of the liquid hydrocarbon downstream of the coalescing medium and separates water droplets of the liquid hydrocarbon from the liquid hydrocarbon. At least one precipitation gap is formed between the coalescing medium and the separating medium.

A wedge shaped filter element for use with a variety of fluids and fluid mixtures is disclosed. Greater in filtration efficiency is provided due to increased filter media and compact arrangement that can be provided with a plurality of filter elements in filter housing. The wedge shaped filter elements can be used for filtration, coalescing fluids and separation of gas from liquid.

A process for extracting bitumen from weathered oil sand ore is provided, comprising mixing the weathered oil sand ore with heated water and sodium triphosphate to form a weathered oil sand slurry; adding sodium triphosphate to either the weathered oil sand ore, the heated water, or to the weathered oil sand slurry; conditioning the weathered oil sand slurry at a temperature of at least 50 C. to form a conditioned weathered oil sand slurry; and subjecting the conditioned weathered oil sand slurry to gravity separation at a temperature of at least 50 C. to form a bitumen froth product.

A liquid cleaning system rests on a surface having a non-porous material covering and a drain. A lower plate layer and an upper plate layer each have runners arranged in a grid. The lower plate layer rests upon the surface and the upper plate layer rests upon the lower plate layer offset at an angle with respect to the grid of the lower plate layer. An upper layer covers the upper plate layer and has a plurality of holes for the passage of fluids into the liquid cleaning system. As liquid enters the liquid cleaning system through the holes, the liquid traverses the grid of the lower plate layer and the grid of the upper plate layer flowing towards the drain, and contaminants within the liquid collect within the grid of the lower plate layer and the grid of the upper plate layer.

A method for separating organic solvent(s) from an aqueous process stream including organic solvent(s), includes passing the aqueous stream including organic solvent(s) through a granular bed including glass granules, wherein at least 90% of said glass granules have a maximum particle diameter smaller than 1.0 mm.

An apparatus for filtering solid and/or non-dissolved contaminants entrained in flowing water, the apparatus comprising an inlet for the water containing the entrained solid or non-dissolved contaminants to flow into a filtering chamber; a first outlet for expelling the unfiltered water from the filtering chamber; the filtering chamber further comprising: a curved or corner portion in the filtering chamber providing at least a part of a flow path of water from the inlet to the first outlet such that flow of the water along the curved or corner portion changes the direction of flow of the water; and a filtering screen for filtration of solid and/or non-dissolved contaminants from the influent water thereby allowing passage of filtered water out of the filtering chamber.

A process for separating a phase (A) comprising at least one ionic liquid from a phase (B), where phase (A) has a higher viscosity than phase (B), comprising: a) providing a stream (S1) comprising a dispersion (D1) in which phase (A) is dispersed in phase (B), b) introducing stream (S1) into a coalescing device (KV), where the inflow rate of stream (S1) is from 0.05 to 150 kg/(cm.sup.2*h) based on the average cross-sectional area of coalescing device (KV), wherein the packing density of coalescing device (KV) is from 50 to 500 kg/m.sup.3, separating phase (A) from phase (B) in coalescing device (KV), discharging a stream (S2) comprising at least 70% by weight of phase (A) from coalescing device (KV) and discharging a stream (S3) comprising at least 70% by weight of phase (B) from coalescing device (KV).

A fuel filtration system configured to separate water from fuel is described. The system includes a housing having an inlet for receiving fuel to be filtered, an outlet for supplying filtered fuel to a device, and an internal compartment having a drain. A filter media is positioned within the internal compartment of the housing, the filter media configured to separate the water from the fuel, the separated water routed out of the internal compartment through the drain. A solenoid valve is configured to provide both the separated water and fuel to an exhaust after-treatment device in fluid communication with the fuel filtration system.
