A water filtration system is also disclosed. The water filtration system includes a regenerative media filter vessel, a filtrate line, a feed line, a recirculation line, a gas line, and at least one pump. A method of filtering water in a system comprising a regenerative media filter is disclosed. The method includes operating the system in a filtration mode, operating the system in a cleaning mode responsive to a differential pressure measurement across the regenerative media filter, operating the system in an aeration mode, operating the system in a pre-filtration mode after operating the system in the cleaning mode, operating the system in a drain mode, and operating the system in the filtration mode following the drain mode. A controller and non-transitory computer-readable medium having computer-readable signals stored thereon that define instructions that, as a result of being executed by the controller, instruct the controller to perform a method of operating a water filtration system are disclosed.

The present invention relates to a water purification housing capable of purifying water and a rainwater purification system using the same. The water purification housing according to the present invention comprises a means that can filter treated water by filling filter media in a housing body and then passing the treated water through the filter media and a mean that can remove residue caught in the filter media as a result of the use of the filter media by collecting the residue in a sediment discharge container positioned at a bottom portion of the housing body. The rainwater purification system according to the present invention comprises a means that connects and installs several water purification housings and an additional filtration means including fiber filter and UV lamp which can filter materials that cannot be filtered only by the filter media at the end thereof.

Disclosed are a wastewater filtering method and apparatus comprising filter media of different sizes. According to one aspect of the present embodiment, provided a wastewater filtering method and apparatus capable of stable and efficient operation by minimizing the head loss as well as simultaneously removing organic matter and solids in a large flow of wastewater.

A regenerative media filter vessel is provided. The regenerative media filter vessel includes a first inlet, a first outlet, and a tube sheet comprising a plurality of tube elements. A portion of the tube element is disposed within a frame positioned about a periphery of tube element and configured to prevent contact between adjacent tube elements. Also disclosed is a method of facilitating water filtration using a regenerative media filter vessel. The method includes providing a regenerative media filter vessel of this disclosure. The method further includes providing the particulate media.

The present disclosure provides improved methods for conducting a wash cycle in a filtration unit. The methods may be used alone or in combination with one another to achieve the improvements described herein. Filtration units adapted for carrying out the novel methods are also provided. Through the use of the methods and filtration units described, significant economic benefits are obtained without a significant increase in the costs of the filtration unit or in the costs of operation of the filtration unit.

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.

Vaults, boxes, chambers, systems, and methods of treatment systems to capture pollutants from storm water runoff and prevent the conveyance of these pollutants from entering a receiving water body or landscape area, which is designed to be a part of a local permanent storm water drainage infrastructure. The system enhances the removal efficiency of almost any type of filtration media by increasing contact time between storm water runoff and the media, and also offers an easy and inexpensive method for serving the media, without having to remove or replace the media. A media filter can include a bottom screen, a media layer, and at least one top lid that can be opened to allow for backwashing of the media layer without removing the media layer from the filter. A servicing system can include pivotal spray heads to pivot to parallel positions over a sloped floor to flush debris toward easy to reach locations to be vacuumed, and vertical spray heads which can break up debris bridges.

A water purification housing capable of purifying water and a rainwater purification system using the water purification housing are provided. The water purification housing filters treated water by filling filter media in a housing body and then passing the treated water through the filter media and removes residue caught in the filter media as a result of the use of the filter media by collecting the residue in a sediment discharge container positioned at a bottom portion of the housing body. The rainwater purification system includes an element that connects and installs several water purification housings and an additional filtration element including fiber filter and UV lamp which can filter materials that cannot be filtered only by the filter media at the end of the rainwater purification system.
