A cationic composite filter aid may include a silicate substrate, a silica precipitated on the silicate substrate, and a cationic surface modification of the precipitated silica. A method for making a cationic composite filter aid may include providing a silicate substrate, precipitating a silica onto the silicate substrate to form a composite filter aid, and cationically modifying the precipitated silica to form a cationic composite filter aid. A method for filtering a liquid may include providing a liquid for filtering and filtering the liquid through a cationically modified composite filter aid. The cationically modified composite filter aid may include a silicate substrate, a precipitated silica, and a cationic surface modification of the precipitated silica.

A filter cartridge for a whole house water filter includes a cylindrical, or tubular, filter media coupled to a mixer tank with improved high flow mixing features. The mixer tank includes a bowl in which a flow diverter, a flow guide with angled fins and a filter media are provided. The flow diverter has a concave portion, i.e., a mushroom-shaped portion, the interior of which is in fluid connection with a central passage through which filtered water flows. In operation, the filtered water flows through the central passage and is deflected by the concave interior of the flow diverter down through the angled fins of the flow guide. The filtered water then passes out through an outlet. The mixer tank stirs the filter media and water mix to increase the kinetics of the mixing process.

A treatment module including a housing having an input port and an output port; a plurality of treatment members, each treatment member having a skeleton and a mesh material provided over the skeleton, the mesh material being joined to the skeleton at one or more portions of the skeleton; and a layer of particles formed over a first side of the mesh material, the layer having pores of sufficient size to enable a fluid to flow through the layer.

A particulate material includes agglomerated diatomaceous earth and a silicone binder. A process for preparing a diatomaceous earth product includes agglomerating at least one natural diatomaceous earth with at least one silicone material, and subjecting the agglomerated diatomaceous earth to at least one heat treatment at a temperature ranging from about 600° C. to about 1,000° C. A filter aid composition includes a diatomaceous earth product including an agglomerated diatomaceous earth and a silicone material. A method of filtering at least one liquid includes passing the at least one liquid through at least one filter membrane including a diatomaceous earth product including agglomerated diatomaceous earth and a silicone material.

An oil deterioration prevention device is provided that can prevent an increase in pressure loss by reducing oilflow resistance. The oil deterioration prevention device may include a filtering unit including a filter element that filters oil, and a deterioration prevention unit including a powdery deterioration prevention agent that prevents deterioration of oil, wherein the deterioration prevention unit includes a passage wall that retains the deterioration prevention agent and forms an oil passage.

A filter monitor system (“FMS”) module is installed on the engine/vehicle and is connected to the filter systems, sensors and devices to monitor various performance parameters. The module also connects to the engine control module (“ECM”) and draws parameters from the ECM. The FMS module is capable of interfacing with various output devices such as a smartphone application, a display monitor, an OEM telematics system or a service technician's tool on a computer. The FMS module consists of hardware and software algorithms which constantly monitor filter systems and provide information to the end-user. FMS module provides necessary inputs and outputs for electronic sensors and devices.

The present invention relates to a method for converting a full flow oil and/or fuel filter system into a bypass filter system comprising the use of a retro-fittable bypass filter configured to directly replace the pre-existing full flow filter, without the need for additional hoses or mounts etc. as in existing methods. Also described is a filter device for converting a full flow oil and/or fuel filter system into a bypass filter system comprising: an inlet for allowing fluid into the filter; a plurality of screens for filtering particles from the fluid; a cellulose element for filtering moisture from the fluid; an outlet for allowing fluid out of the filter; and a bypass for fluid to bypass the cellulose element and at least one screen and exit the filter, wherein the bypass filter is configured to directly replace the pre-existing full flow filter.
