Moreover, the present invention is also related to a handheld shower unit (9) for an apparatus (1).

Disclosed herein is a device for facilitating siphoning of greywater (graywater) or gently used water. An adapter is designed to fit onto the end of a hose or tube. The adapter is manually held tightly or attached by friction to a spigot or faucet. The faucet is turned on and running water primes the hose. The adapter is then placed under the surface of a collection of greywater in a sink, tub, clothes washer and the like. Greywater is then allowed to flow to a garden, lawn, cistern or other place where the greywater can be put to use instead of shunting it into a sewer. The device includes a funnel-shaped portion and a threaded portion. The device is made from a pliant material such as a silicone rubber or plastic.

The invention relates to a heat recovery unit to transfer heat from a gray water source discharged from a bath or a shower to preheat fresh cold water supplying a bath, a shower, a boiler system or hot water heater. The heat recovery unit comprises an inner tube, an outer tube, a non-return valve, an anode, deflectors as well as associated piping and fittings. Fresh water from a pressurized public network or well flows through the inner tube while the gray water flows between the inner and outer tubes. The non-return valve installed in the fresh water pipe prevents contamination of the drinking water system. A translucent pipe may be installed in a section of the gray water piping system to detect any leaks. An insulated jacket may be placed around the unit to reduce heat loss. The heat recovery unit may be used in domestic, commercial, industrial and institutional buildings.

According to embodiments of the present disclosure is a water delivery system that continuously flows and recirculates clean water, diverting only water that has touched a user's hands. No sensing is required to activate the water flow and the actions of the user effectively divert the dirty water to a drain. The water delivery system comprises a clean water outlet, a clean water inlet, a dirty water drain, and a circulation pump. A stream of water continuously flows from the outlet and is received by the water inlet if the stream is uninterrupted. If the stream is disturbed, such as by the hand washing activities of the user, the stream is diverted from the inlet and instead falls into a sink and into the drain.

This specification describes systems for the treatment and reuse of greywater and related processes. An exemplary system collects greywater from baths and showers and treats it for use in toilet flushing. Influent bathing water passes through a prefilter to remove larger particles and flows into a greywater collection tank. Collected greywater is filtered through a membrane designed to remove suspended solids. Membrane permeate passes through a sorbent media to remove soluble organics and then flows into a permeate tank. A chemical agent is used to disinfect water in one or more parts of the system and optionally to clean the membranes. A control system manages the operation of system. The system operates in a generally daily cycle with permeation dispersed over a material time, for example 4 or 8 hours or more.

The present disclosure relates to a recirculating shower system. The recirculating shower system may include a first shower outlet and a second shower outlet. The recirculating shower system may include a fresh water conduit fluidly coupled to the first shower outlet and a recirculated fluid conduit fluidly coupled to the second shower outlet. The fresh water conduit and the recirculated fluid conduit may be arranged such that warmer fresh water flowing through the fresh water conduit may heat cooler recirculated fluid flowing through the recirculated fluid conduit.

The present inventive concept relates to a water recycling device comprising: an outlet configured to output treated water; a drain for collecting used water output from said outlet; a return/evacuation path in liquid communication with said drain, wherein said return/evacuation path comprises an inlet for receiving water collected by said drain; a return path in liquid communication with said return/evacuation path; a treatment path in liquid communication with said return path and said outlet; an external water path in liquid communication with said treatment path, said external water path being connected to an external water outlet; a valve arrangement configured to accept as inputs used water from said return path and/or external water from said external water path, said valve arrangement being placed between said return path and said treatment path, said valve arrangement being configured to direct said inputs to said treatment path, said valve arrangement being configured to mix said external water with said used water from said return path; a circulation pump for providing a flow in said water recycling device; and a water treatment arrangement placed downstream of said valve arrangement.

The present invention describes a liquid recycling system and method for purifying and either recirculating or discarding of liquid. The system includes a liquid input line, a tank, and a circulation pump for providing recirculation of liquid from the tank. A filter and a heater are used to treat liquid from the circulation pump. A valve is provided to direct liquid either to a shower head or faucet, or back to the tank. Additional plumbing and components can be used to provide multiple independent recirculation loops with the tank. An electronic controller can be used to control components of the present invention, where a user could interface with the controller via a control panel or a software application accessed by a portable electronic device.
