A water monitoring device monitors and maintains swimming pool chemistry. The device mixes reagents with water in flowcells. The water chemistry is detected by measuring the light transmitted through the flowcells. The water monitoring device can communicate with computers, servers and mobile computing devices which can store and display the water chemistry information. The reagents can be stored in a replaceable reagent cartridge which can provide reagents for water testing and can be replaced when the reagents need to be replenished.

There is described a water monitoring device for monitoring a body of water. The body of water comprises a main body of water and a water inlet and/or water outlet. The water monitoring device comprises a sensor operable to generate data in relation to a property of the body of water, an attachment member operable to removably arrange the device in a substantially stationary position adjacent to the water inlet and/or water outlet of the body of water; and a communication member operable to transmit the data relating to a property of the body of water to a remote device. Also described is a water monitoring apparatus and a method of monitoring a body of water.

Systems and methods that provide enhanced capability for toilets and bathrooms in general by adding feature sets such as user weighing, leak detection, enhanced toilet cleaning/deodorizing and other features, connected over networks to user devices and servers, creating a complete bathroom ecology where users have direct and remote control and access to system functions and data, and server based bathroom support applications provide a wide range of capabilities including user control and readout of toilet systems functions, bathroom condition, supply levels, and health data.

A water use management system may be installed in a setting that contains a primary infrastructure for water use to provide an alternate, modular infrastructure for water use. Fresh water used at various points of use, such as a shower or sink, may be diverted into the modular infrastructure prior to draining into the primary infrastructure. Once diverted, the precedent use water is received at a reservoir system where it is treated for a subsequent use. Treatment may include filtration and/or chemical treatment, and may be based upon sensor feedback from the reservoir system. Once treated, the water is ready for subsequent use and may flow from the reservoir system, via the modular infrastructure, to a subsequent point of use, such as a toilet.

In one embodiment, a differential water data analysis system includes a data storage, a user interface, and a processor coupled to the data storage and programmed with software to: receive inflow water measurement data from a water inflow line entering a water treatment system and outflow water measurement data from a water outflow line exiting the water treatment system, the inflow water measurement data and outflow water measurement data being obtained by measuring the water in the water inflow line and the water outflow line at about the same time and being received in real time; compare the inflow water measurement data and the outflow water measurement data; compute a performance of the water treatment system based on the comparison using a computation scheme; determine whether the performance is within specification of the water treatment system to produce a determination output; and display the determination output in the user interface.

A method of filtering fluid for injection into an injection well comprises detecting a fluid pressure in a conduit upstream of an actuator valve, verifying that the fluid pressure is within an operating pressure range, opening an actuator valve based on the verifying, receiving a fluid having suspended solids within a filter assembly in response to opening the actuator valve, actuating a pump in fluid communication with the filter assembly based on receiving the fluid within the filter assembly, and separating at least a portion of the suspended solids in the fluid within the filter assembly.

Provided are an anaerobic ammoxidation synergistic nitrogen removal process device of municipal sewage main and side streams and an application method thereof, comprising a municipal sewage raw water tank (1), a biological reaction pool (2), a secondary sedimentation pool (3), a sludge digestion solution raw water tank (4) and a sludge digestion solution AOB strengthening pool (5); wherein, the municipal sewage raw water tank (1) is connected with a water inlet valve (2.2) of the biological reaction pool (2) through a water inlet pump (2.1) of the biological reaction pool (2); the biological reaction pool (2) is connected with the secondary sedimentation pool (3) through a secondary sedimentation pool connection pipe (3.3); the sludge digestion solution raw water tank (4) is connected with a water outlet valve (4.1) of the sludge digestion solution raw water tank (4) through a water inlet pump (4.2) of the sludge digestion solution raw water tank (4); the sludge digestion solution AOB strengthening pool (5) is connected with an anaerobic ammoxidation region compartment of the biological reaction pool through a sludge-water mixture reflux pipe (5.8) and a sludge-water mixture reflux pump (5.11). It has the advantages of reasonability in structure design, convenience in operation, low running and maintenance cost, relatively low energy consumption, no need of an additional carbon source and the like, it can realize that short distance nitrification of municipal sewage is more stable, and it is high in low-temperature, water quantity and water quality shock resistance and can further increase volumetric load at the same time.

The present invention is an automated electromechanical gripper for handling a container. In one embodiment, the gripper is used in an automated liquid dispenser. The gripper can grab a single container, remove the container from a nested stack of containers, and move the container in three directions (horizontally, laterally, and vertically).

A method for operating a water treatment plant comprises a phase of detecting anomalies in the operation of the plant, wherein the phase of detecting anomalies comprises an implementation of the following measures: providing data representative of the operating state of the plant, said data being provided by sensors installed at selected locations in the plant itself or on input or output pipes of the plant; where appropriate, providing additional data; and providing a system for acquiring and processing these data, this system being equipped with an algorithm for processing said data.

A water treatment system, a water treatment monitoring and/or control system, and a method of monitoring and/or controlling treatment of water are disclosed. The water treatment system generally includes a water pump configured to supply water from a water source to an intake pipe, a chlorine source pump configured to supply a chlorine source from a storage vessel to a chlorine source feed line, a water flow and/or pressure switch configured to detect a positive water flow and/or pressure in the intake pipe, a chlorine flow monitor, and logic or circuitry configured to notify a user and optionally automatically disable or turn off the water pump when (1) the water flow and/or pressure switch detects the positive water flow and/or pressure in the intake pipe and (2) the chlorine source flow monitor detects either that (i) the chlorine source pump is not primed or (ii) there is no flow in the chlorine source feed line. The chlorine flow monitor is configured to determine (a) whether the chlorine source pump is primed or (ii) there is no flow of the chlorine source in the chlorine source feed line. The monitoring/control system and method generally embody one or more of the inventive concepts disclosed herein.
