METHOD AND APPARATUS FOR TREATING COMMERCIAL AND INDUSTRIAL LAUNDRY WASTEWATER
The present invention relates generally to an effluent treatment device including in one embodiment a skid configuration. The method and apparatus of the present invention can use only two fluid pump units and including individual or multiple membrane modules in a stacked longitudinally arranged configuration. The stacked or in series modules can be either vertical or horizontal forming a column. The membrane modules are contained in large diameter pipes with enough space around each module so that filtered permeate water collects in the pipe and backwash water can flow in the pipe to backwash the modules and contained membranes. The present invention includes one or more hollow fiber ceramic membrane modules which each includes multiple hollow fibers bundled together by end or band caps (e.g., ceramic, epoxy of glass material end caps) to form a complete membrane module. A complete hollow fiber membrane module can comprise multiple symmetric individual hollow fibers between about 2.0 to 4.00 millimeters inside diameter and can be made of aluminium oxide (Al.sub.2O.sub.3) substrate material. The geometry of the individual ceramic fiber walls can be between about 1.0 to 2.0 millimeters in thickness, known as the membrane wall. Such ceramic hollow fibers can have pores including a range of nominal 1 nanometer to 1400 nanometers. The ceramic hollow fibers can comprise selective membranes pores including a range of nominal 1 nanometer to 1400 nanometers which may include individual or multiple separating layers attached to the fiber walls of nominal 1 to 100 nanometers. The separating layers can each be a porous polymeric material. In one embodiment, a skid mounted treatment device is operable to pass water through an individual hollow fiber ceramic membrane module or multiple membrane modules in series known as a membrane loop. Filtration is inside to out flow filtration through the hollow fiber membranes. The apparatus is also operable to pass water through the hollow fiber ceramic filter module or multiple membrane modules in an outside to in flow direction, so as to remove material from the separation layer of the hollow fiber ceramic membrane fibers, a process known as backwashing or back flushing. Contaminant materials (retentate) having been deposited during inside-out filtration of the commercial or industrial laundry effluent is removed with such back flushing.
Method and Apparatus To Implement A Managed Distributed Wastewater Process
The method of the managed sewer is a Netcentric distributed process that is managed in real-time and implemented through several apparatuses that enable the low capital cost and low installation cost of a smaller diameter pipe (smaller than typically used in gravity flow systems). The apparatuses enable the method of managing the grinding, pumping and staging processes to optimize the effectiveness of the collection process through the small pipe and increase system efficacy by using the pumping and transport action of the material in the pipe as part of the process activity.

System and method for recovering and reusing graywater
The present disclosure provides a system for recovering and reusing graywater generated from at least one graywater source in a building. The system includes a controller configured to control recovery and reuse of the graywater; a graywater recovery device communicably coupled to the controller and configured to recover the graywater from the graywater source of the building; and a graywater distributor communicably coupled to the controller, connected to the graywater recovery device, and configured to distribute the recovered graywater to at least one target position in the building for reuse, wherein the controller controls the graywater recovery device to deliver the graywater to the graywater distributor according to a control signal sent by a user, and the controller controls the graywater distributor to deliver the graywater to a target position designated by the user for reuse according to a control signal sent by the user.
EVAPORATIVE COOLING SYSTEM FOR ABLUTION BAY
An indirect evaporative cooling system for cooling a space adjacent to or containing an ablution bay is described. The indirect evaporative cooling system includes a greywater source from the ablution bay and evaporative cooler apparatus located above the space to be cooled in a dome shaped housing. The evaporative cooler apparatus includes a wet channel, at least one spray nozzle, and a dry channel. The at least one spray nozzle is located at the top of the evaporative cooler apparatus and is fluidly connected to the greywater source and the wet channel.

PROCESS FOR REDUCING TOTAL SUSPENDED SOLIDS (TSS), BIOCHEMICAL OXYGEN DEMAND (BOD), CHEMICAL OXYGEN DEMAND (COD) IN COMMERCIAL LAUNDRY
Methods and systems of treating textile wastewater may involve reducing the pH of the wastewater to a threshold pH range prior to adding a transition metal source and oxidizing agent to the wastewater for reducing total suspended solids (TSS), biochemical oxygen demand (BOD), and chemical oxygen demand (COD). The system design allows for optimum residence time for the chemistry to interact with wastewater effluent and remove unwanted precipitates within the wastewater source. Beneficially, the methods and systems can remove precipitates in a continuous system without the need for filtration systems.
METHOD FOR TREATING WATER
A method of removing microplastic particles from a water-based liquid, comprising the exposure of the liquid to a solid surface on which is retained a sorbitan monooleate surfactant, in a concentration suitable for entrapping substantially all microplastic particles. The method is useful for removing microplastic particles and microfibres from fresh and saline natural waters, effluent water, such as grey water, storm water and waste waters from industrial processes, in addition to any kind of product based on water, such as mineral waters, milk, fruit juices, beverages, pharmaceutical and veterinary products.
Household appliance with coagulant dosing system
Laundry treatment appliances for use in a typical household include a tub that has an opening to provide access to the interior and at least partially defines a treating chamber into which fabric items such as clothes, towels, or linens can be placed to undergo a washing operation. A system can be provided for recirculating wash liquid through the tub to reduce water consumption. At least one tank or reservoir and a coagulant dosing system can be included for the chemical treatment of wash water as part of the wash liquid recirculation system. The tank can also serve to separate coagulated solids from the wash water.
