A self-cleaning, automated apparatus with a filter for fluids includes a nozzle unit assembly that has a first tube inside a second tube. Each of the tubes has a different pattern of one or more slots or holes. One tube rotates while the other is fixed, so that part of the pattern of one coincides with the other at times, resulting in a jet of cleaning fluid that removes debris from a filter. The filter is rotated so the jet can reach all parts to be cleaned. The pattern of the rotating tube may approximate a helix and the pattern of the fixed tube may approximate a line.

A composition for cleaning water using an electrolytic chlorine generator includes an oxidizer, a pH reducer, a flocculent, a chelator, and a borate compound. A method of cleaning water treated with an electrolytic chlorine generator includes adding, to a body of water treated with an electrolytic chlorine generator, the composition.

A method for reducing fouling in an aqueous system of an olefin production plant is disclosed. The method includes adding an effective amount of a surfmer to the aqueous system, wherein the surfmer forms a water soluble adduct by covalently bonding to one or more fouling precursor compounds formed during olefin production.

The present invention relates to a water purifier comprising a body having an external appearance of a shape able to hold water, and a discharge device which is located inside the body and discharges the water held in the body to the outside of the body; wherein the discharge device comprises a discharge unit body which has a hollow shape that provides a flow pathway for discharging the water held in the body, and a light-source unit which is disposed facing the discharge unit body and irradiates light having the wavelength band of ultraviolet light towards water flowing through the discharge unit body.

A water evaporation system includes an evaporation module configured to evaporate water from a brine; a support module attached to the evaporation module and configured to support the evaporation module above the brine; and an inlet configured to add a crystal growth inhibitor to the brine.

Methods and apparatus for monitoring process water within a food processing system are provided. One example water control system for a food processing system generally includes a temperature adjustment element having an inlet and an outlet and a sensor coupled to the outlet of the temperature adjust element. The temperature adjustment element is configured to: receive, at the inlet, a portion of process water from a process water supply in a stage of the food processing system, the process water in the process water supply and the received portion of the process water having a first temperature; and cause the portion of the process water at the outlet to have a second temperature, different from the first temperature. The sensor is configured to measure at least one property of the portion of the process water received from the outlet of the temperature adjustment element.

A pool cleaning robot that may include a filtering unit for filtering fluid that passes through the filtering unit; a calorimetric sensor for sensing a cleanliness related parameter of the filtering unit while the pool cleaning robot is submerged in the fluid; and a controller that is configured to at least assist in determining, based on the cleanliness related parameter of the filtering unit, a cleanliness of the filtering unit.

Apparatus and a method for cleaning accumulated sediment from storm drain conduits and other large-diameter conduits. A nozzle assembly is arranged to deliver a high-volume flow of water at a pressure high enough to loosen sediment from the interior of a conduit and to propel the nozzle assembly and an associated nozzle feed hose upstream within a conduit being cleaned. Water from the nozzle assembly flushes the sediment downstream and is then collected, partially cleaned, and reused in the nozzle assembly. Mud and clay may be left in the water to increase its specific gravity and viscosity. A self-contained portable and mobile system includes a tank and apparatus for removal of high concentrations of entrained or suspended solids, and a pump and conduits for delivering a high-volume flow of water, containing quantities of suspended solids, to the nozzle assembly.

A method for real-time monitoring of a water purification apparatus includes obtaining a first Total dissolved solid (TDS) data, a first flow rate, and a first pressure data of unfiltered input water through a first sensor module. A second TDS data, a second flow rate, and a second pressure data of filtered water is obtained through a second sensor module. Thereafter, a third TDS data, a third flow rate, and a third pressure data of post-filtered water is obtained through a third sensor module. Later, data collected by the sensor modules is transmitted to a remote processor in real-time, and the received data is analysed in real-time. Finally, a predictive model of water behaviour and water quality of the water purification system is generated, using an Artificial Intelligence (AI) based process, based on the real-time quality analysis, and one or more user actions are suggested based on the predictive model.
