The invention provides methods and compositions for reducing the amount of water required in an industrial process, especially a bottling process such as beer or beverage manufacturing. The method comprising the steps of: collecting water used to rinse cleaned and/or dirty recycled bottles, spraying the collected water at a food contacting piece of equipment as part of a CIP rinse, and passing the CIP second rinse water into a cooling tower as make-up water. The method allows for the re-use of water already in the system but by being careful where each water stream goes the water does not accumulate contaminants that would damage the cooling tower or foul the bottled product or vessel that is cleaned by CIP method.

The present invention provides a system for high throughput purification of liquid.

A filtration system for a pet water fountain is provided. The filtration system utilizes a pump placed within or along a watering bowl. The water filtration system also utilizes a multi-stage filtering device. In one aspect, the multi-stage filtering device includes a first filtering stage representing copper zinc alloy particles, and a second filtering stage representing granulated activated carbon particles. Each stage may constitute filtering material that is separated into an array of cells residing along a vertical frame or is separated into stages placed in series within a tubular cartridge. A method for filtering water in a pet fountain is also provided herein.

Methods and systems for removing pollutants from water include one or more filter systems and a hybrid wetland system. Hybrid wetland systems may include a first pipe transporting water from a body of water to a settling tank, a first constructed wetland connected to the settling tank via a second pipe, and a first filter system removing pollutants from water passing through the second pipe. A second filter system is positioned within the first wetland to further remove pollutants. The system also includes a second constructed wetland connected to the first constructed wetland via a third pipe and a water control chamber. Filtered water exiting the first constructed wetland flows through the water control chamber, through the third pipe, and into the second constructed wetland. A fourth pipe extends between the second constructed wetland and the body of water, returning filtered water to the body of water.

Low strength wastewater such as municipal sewage is treated using an anaerobic digester. In some examples, a wastewater stream is separated into a solids rich portion and a solids lean portion. The solids lean portion is treated, for example to remove nitrogen. The solids rich portion is treated in an anaerobic digester, preferably with influent or recuperative thickening. In another example, the wastewater stream is fed to an anaerobic digester and solid-liquid separation stages downstream of the digester return active bacteria and undigested organics to the digester. Both cases may use a process train comprising treatment in an anoxic tank followed by a nitritation tank with a portion of the effluent from the nitritation tank recirculated to the anoxic tank to provide nitritation and denitritation.

A metal surface treatment liquid recycling system includes a treatment liquid collecting tank, a pre-treatment device, a nanofiltration device and a vacuum distillation device, all of which are connected sequentially. The nanofiltration device includes a feed tank, a first-stage nanofiltration membrane unit, and a second-stage nanofiltration membrane unit. Treatment wastewater in the treatment liquid collecting tank is fed into the pre-treatment device to filter out suspended solids and then enter the feed tank. The wastewater in the feed tank is filtered by the first-stage nanofiltration membrane unit and transformed to a first-stage concentrated waste liquid and first-stage infiltration fluids. The first-stage infiltration fluids are fed into and re-filtered by the second-stage nanofiltration membrane unit and transformed to a second-stage concentrated waste liquid and second-stage infiltration fluids. The second-stage infiltration fluids are evaporated and concentrated by the vacuum distillation device for generation of distilled water and high-concentration acid concentrated fluids.

The present disclosure relates to a system and process for separating sand and gravel in sediments of a sewage pipe network and recycling organic matters. The system includes a conveying grid plate, a mud outlet is provided below the conveying grid plate, and a masonry conveying area is provided at one side of the conveying grid plate; a fiber crushing tank, disposed below the mud outlet, and a crushing device is disposed below the mud outlet; a masonry scouring and recycling tank, provided with an interception grille located at one side of the masonry conveying area, a flushing device is disposed above the interception grille, a masonry outlet is provided in the masonry scouring and recycling tank, the masonry scouring and recycling tank is communicated with a muddy water return pipe, and the muddy water return pipe is communicated with the mud outlet.

An apparatus for collecting debris includes a frame having a connector configured to attach to a pole. The frame includes a plurality of frame rods each designed to be removably connected to at least one other frame rod via a tongue-and-groove feature such that the plurality of frame rods define an opening when connected together. The apparatus further includes a netting designed to be removably connected to the frame and to substantially fill the opening defined by the plurality of frame rods.

Disclosed herein is a flocculation basin inclusion ion type water treatment apparatus using dissolved air floatation which includes: a flocculation basin which forms flocs by mixing a coagulant inserted into feed water and grows up the flocs; a contact zone to which fine bubbles are induced through a nozzle disposed at a lower part; and a separation zone which removes the flocs when the fine bubbles are attached to the flocs and the flocs float on the surface of water, the flocculation basin inclusion type water treatment apparatus including: a fine bubble forming part configured to separate a portion of the feed water at an upstream side of the flocculation basin by piping, configured to form saturated water using the separated portion of the feed water and configured to supply the saturated water to the nozzle.

Methods, apparatus, and systems are provided for detecting and removing microplastics from wastewater effluent. Both, automatic/remote and manual monitoring and sampling components are included to detect the presence of microplastics. The automatic monitoring and sampling component includes a TSS sensor and associated apparatus calibrated to account for non-plastic solids present in the wastewater and, thereby, more accurately determine the presence of microplastics. Efficient separation and removal of microplastics from wastewater effluent is performed by a specialized capture net apparatus having multiple sized mesh components and optional diffuser devices which perform size exclusion filtration of microplastics from the water. In an exemplary embodiment, the methods generally include diverting treated wastewater effluent from a wastewater treatment facility's main line into a wastewater sampling mechanism via an intake pipe, and then into a solids monitoring and separation mechanism which includes the specialized capture net apparatus.
