The present invention is a two-part irrigation system that utilizes both groundwater and rainwater. The first system extracts water from groundwater layers by using extraction pipes filled with nanomilled sand that constantly moves water upwards through capillary action. The second is a rainwater collection and capillary irrigation system. The groundwater irrigation system consists of an external groundwater transport pipe filled with nanomilled sand. This encapsulates an empty internal transport pipe that delivers percolated water. The rainwater irrigation system consists of a collection, storage, filtration, and capillary irrigation system. Rainwater is collected by trays and a water tank, where the water is filtered through a hollow fiber membrane filter. This clean water is used as potable drinking water or for irrigation. The water volume required for irrigation is calculated based on moisture data collected by moisture detection devices. Both systems are solar powered, and are controlled and programmed by the user.

The present invention relates to a residential home water filter system and method. The water filter system comprises a filter stage, a water purification stage, a water storage stage, and a back-up water softening stage, to deliver filtered and purified water to consumers when needed. Water from a pressurized water source first flows through filter 16 and then to a first junction 18 to a reverse osmosis system 22 when a pump 24 is activated or to an ion exchange water softener 20 when the pump 24 is deactivated. The filtered and purified water is then stored in tank 26.

A bilayer electrospun membranes for treating hydraulic fracking wastewater via membrane distillation, and more particularly to bilayer electrospun membranes having an omniphobic layer to prevent low-surface tension solution wicking and an oleophobic antifouling surface to prevent foulant depositing on the membrane. Nanoparticles are decorated on the omniphobic surface through electrochemical interaction, which is coated with a fluorine monomer on the nanoparticles. A zwitterionic co-polymer is grafted using self-assembly between hydroxy groups on the antifouling surface generated by alkaline treatment and anchor segment epoxy groups on zwitterionic co-polymer.

An in-line fitment for connection of a filter to a pipe includes first and second fluid-carrying portions and a non-fluid-carrying spacer. Each fluid-carrying portion includes a socket for receiving an open end of a pipe and a connector for connection of the filter. A screw compression fitting is provided on each of the sockets of the first and second fluid-carrying portions for forming a sealed connection with the open ends of the pipe. The socket of the first fluid-carrying portion has a pipe receiving depth greater than that of the socket of the second fluid-carrying portion for enabling movement of the fitment parallel to the pipe when engaged with one of the open ends of the pipe. The sockets of the first and second fluid-carrying portions are positioned on a common axis and facing away from each other when the fluid-carrying portions are linked by the spacer.

The present invention relates to systems and methods for cleaning materials, such as flooring and upholstery. In some cases, the systems and methods use an electrolytic cell to electrolyze a solution comprising sodium carbonate, sodium bicarbonate, sodium acetate, sodium percarbonate, potassium carbonate, potassium bicarbonate, and/or any other suitable chemical to generate electrolyzed alkaline water and/or electrolyzed oxidizing water. In some cases, the cell comprises a recirculation loop that recirculates anolyte through an anode compartment of the cell. In some cases, the cell further comprises a senor and a processor, where the processor is configured to automatically change an operation of the cell, based on a reading from the sensor. In some cases, a fluid flows past a magnet before entering the cell. In some additional cases, fluid from the cell is conditioned by being split into multiple conduits that run in proximity to each other. Additional implementations are described.

The disclosed systems and method utilize the autofluorescence, optic imaging, and heat transfer resistance technologies to monitor the same simulated surface area for deposits. The systems and methods may provide continuous monitoring, detection, characterization and quantification of deposits. Utilizing this information, an associated control system may initiate alarms, initiate a chemical treatment operation, and adjust corresponding chemical treatment and preventive protocols to minimize and/or eradicate the issue.

Water treatment compositions useful to decrease surface tension of cooling tower waters are provided as are treated cooling tower waters. The compositions increase the transfer of heat from metal surfaces in contact with the treated cooling water. The increased heat transfer can decrease energy use, for example, in water-cooled HVAC and refrigeration compressors, and can enable increased production rates in many industrial processes, including, for example, plastics molding, metal billet production, petroleum refining, power plants, and condensers for steam turbines. Also provided are cooling tower water compositions formulated to control corrosion, scale, and deposition in a cooling tower and in treated cooling tower water.

A system for membrane fouling control configured to run one or more filter cycles, wherein each filter cycle of the one or more filter cycles includes an operation mode and a cleaning mode. The system includes: a first conduct portion; a second conduct portion; a membrane arranged between the first conduct portion and the second conduct portion. The membrane is configured in the operation mode to filter a liquid to be filtered by conducting it from the first conduct portion to the second conduct portion. A fouling control means filled with fouling control particles is added in the operation mode in the first conduct portion so that a dynamic protective layer is formed on the membrane. The fouling control particles are mineral particles based on calcium and/or magnesium.

A method for applying a chemical treatment to a cooling medium in an evaporative cooling system. The method includes applying the chemical treatment to the cooling medium, and the chemical treatment includes at least one of a phosphonate and a dispersant polymer.
