A coalescence filter for purifying a fluid which contains a carrier and at least one liquid contaminant by coalescing of the at least one contaminant, where the coalescence filter includes an inlet for supplying the fluid to a filter element present in the coalescence filter, where the filter element includes a primary coalescence medium which is provided for coalescing of the at least one contaminant in the primary coalescence medium during the displacement of the fluid through the primary coalescence medium. The coalescence filter further includes an outlet for discharging the coalesced contaminant from the filter element, where the primary coalescence medium comprises at least one layer of a porous material, where the primary coalescence medium has a total thickness of at least 3.5 mm.

The invention relates to a process and a device for enriching water, in particular drinking water, with magnesium ions. In order to enable enrichment of water with magnesium ions in exchange for calcium ions and/or heavy metal ions during treatment of water, and in particular of drinking water, it is proposed according to the invention to pass the water through an ion exchanger which contains a weakly acidic ion exchange material, wherein at least a part of its ion exchange capacity is loaded with magnesium ions.

A method for controlling treatment of an industrial water system is disclosed. The method comprises the steps of providing an apparatus for controlling delivery of at least one treatment chemical, the apparatus comprising at least one sensor and an electronic input/output device carrying out a protocol; measuring a parameter of the industrial water system using the at least one sensor; relaying the measured parameter to the electronic device; adjusting the protocol based on the measured parameter; delivering a concentrated treatment chemical into a stream of the industrial water system according to the adjusted protocol, the concentrated treatment chemical comprising an active ingredient, the active ingredient traced as necessary, the active ingredient having a concentration; repeating the measuring, the adjusting, and the delivering; and optionally repeating the steps for n-number of parameters, n-number of active ingredients, and/or n-number of concentrated treatment chemicals.

A water management system provides much improved waterproofing drainage system particularly, but not limited to foundations, new or existing. The includes a form, clean washed stone, soil separating filter cloth, backfilling soil, and drainage pipe to drain out all water away from the structure. This system is easily installed and creates an even “wall” of gravel around structural walls minimizing the costs of materials making it very cost-effective. This system removes all hydrostatic pressure from structural walls eliminating the cause of water infiltration to the interior of basement walls. Water infiltration in basement walls results in mold, mildew, high humidity, and poor air quality.

A ballast water treatment system. Implementations may include an intake screen, a ballast water intake pump coupled to the intake screen, a screen filter coupled to an outlet of the ballast water intake pump, and a multi-cartridge filter system coupled to the screen filter and with one or more ballast tanks A ballast water dump pump may be coupled with the one or more ballast tanks. The multi-cartridge filter system may include two or more cartridge filters including a quaternary organosilane coating produced from a quaternary ammonium organosilane reagent.

The device provided relates to the field of water purification and disinfection. The device for water purification works by exposing water to an hydroxyl radicals and includes a corona discharge reactor, an ejector, at least one solenoid valve, control electronics, a mixing chamber. Inside the reactor there is a group of pin discharge electrodes, an earthen solid electrode, a chamber of saturated vapors of treated water, and the reactor is interfaced to the ejector. The device allows to obtain at the output of the device water with a high degree of purification, as from biological pollution, as well as to get rid of many undesirable chemical compounds present in the source water by their oxidation to safe products.

In a wastewater treatment plant a rag seeding tank is included in a process drain to collect hair and fibers which have passed through headworks of the plant. The hair and fibers tend to join together into large masses downstream of the headworks and can be damaging to process zones, particularly membrane zones. The rag seeding tank includes cartridges filled with surfaces that fibers and hair will attach to, so that hair/fiber rags grow in the seeding tank and are removed therefrom rather than causing problems downstream.

A filter for a non-plumbed appliance is provided. The filter includes a filter housing defining a filter chamber. A filter medium is positioned within the filter chamber, each end of the filter medium being enclosed by an endcap formed from a resilient material, such as molded silicone or a thermoplastic elastomer. The endcaps slide on the ends of the filter media with no need for adhesive and form a fluid seal with both the filter media and the filter housing once installed. One or more fluid bypass channels may be defined by the filter housing or in the endcaps to allow water to flow as desired within the filter chamber. The resulting filter requires fewer components and less assembly time while improving filtration performance and reliability.

An aquarium filtering and purifying system includes an upper display tank and a lower filter tank. The water from the upper tank can be delivered to the lower tank to a filter, such as within a surrounding filter fabric or membrane, such as a filter sock. An air tube can also be inserted into the filter tank to an unfiltered side of the filter, such as within the filter sock, to deliver air bubbles into the filter tank. The air tube can have an air stone at the end thereof to diffuse the air bubbles. Further air stones can be provided on an outside of the sock in the first compartment. Filtered water is delivered to a second compartment in the filter tank. The next compartment can have sand, and/or rocks and/or algae and/or a clean-up crew to assist in purifying the water. Water from the second compartment then passes to a third compartment, through a bubble trap, and then is pumped back to the display tank. Alternatively, the first compartment can be provided with a macro algae bed instead of a filter sock.

Apparatuses, systems, and methods related to water treatment are generally described. In particular, clarifiers that may improve solids thickening and related systems and methods are disclosed.
