Disclosed are a heat exchanger capable of cooling a coolant and a sewage treatment plant comprising same. An aspect of the present embodiment provides a sewage treatment plant which cools a coolant for dissipating heat of each component inside a data center, the sewage treatment plant comprising at least one removal means, for receiving sewage and removing organic material and pollutants in the sewage, and a cooling pipe, through which a coolant which has dissipated the heat of each component inside the data center flows, disposed inside the removal means so as to induce heat exchange between the treated water, from which organic material and pollutants of the sewage have been removed, and the coolant flowing through the cooling pipe, thereby lowering the temperature of the latter.

A distributor plate for a fluid tank such as a water softener pressure vessel separates the resin bed from a lower end of the resin tank. The distributor plate includes a disk that is supported on an upwardly facing surface from below and that is restrained from upward motion by a weld bead located above an outer periphery of the disk. The disk may have an inner slotted plate portion and an outer portion, and wherein the outer portion of the disk has an upper surface having an annular protrusion extending above an upper surface of the slotted plate portion, with an upper surface of the protrusion forms an engagement surface for the weld bead. The disk may be formed from a thermoplastic material having a relatively high dimensional predictability such as high-density polyethylene (HDPE) and unfilled or 30% glass-filled Noryl, respectively.

The invention relates to a filter device comprising an inlet and an outlet. An adsorption section is positioned along the flow path between and inlet section and an outlet section, and is filled with glass beads of a predetermined nominal diameter as well as an absorption granulate mixed with said glass beads. The inlet section and outlet section are filled with glass beads with a nominal diameter preferably at least as big as the nominal diameter of the glass beads of said adsorption section.

Systems, devices, and methods of filtering water include a dome shaped lid and middle disk to separate filtration media materials. The domed shaped lid eliminates air locks in the filter media that can slow or stop the filtration process. A flow control output port regulates the flow level and flow speed of the filtered water. An angled flow output port improves flow by accelerating flow at an angled bottom section of the filter. Water permeable filter bag materials house the filter media. An additional washing process improves the taste of the filtered water. A color change resin in the mixed bed resin indicates expiration of the filter. Similarly, a filter expiration indicator assists users in determining when a filter should be replaced. An integrated TDS meter is used for testing the filtered water. The devices can be used individually or in combination to provide performance improvements.

The invention is directed to methods of providing backwash processes for a synthetic compressible medium filter system. More specifically, the system may include a backwash pump and air blower, and the processes may include at least three sequences of: air and water wash; air purge; and medium compression. The backwash process may be triggered by one or more of a pressure, time point, and/or turbidity set point. The air and water wash sequence may include breaking and washing the medium. The air purge sequence may include removing substantially all of the air entrapped in the medium by providing a backwash water flow for a period of time; and a medium compression sequence compressing the medium while avoiding exposing the medium to air, including introducing raw water and where the backwash and raw water provide enough energy to compress the medium without introduction of air into the medium.

A portable pool filter system is disclosed. The portable pool filter system is fully immersible and self-contained. Water is suction fed through the filter before entering the pump and being discharged. The device decontaminates water from all contaminations to include algae, iron, red clay, and oils.
