摘要： A system for sampling groundwater from a well that includes a pump configured to be at least partially submerged in the groundwater within the well and pump the groundwater out of the well, a sensor configured to output a signal indicative of the depth of the groundwater in the well, and a controller in communication with the sensor. The controller is configured to receive the signal indicative of the depth of the groundwater from the sensor and compensate for groundwater ingress into the well by adjusting a rate of flow of groundwater pumped by the pump based on the signal to stabilize the depth of groundwater in the well while the pump is pumping groundwater from the well.

摘要： To provide a technique capable of facilitating water quality sensor calibration and drainage operations for improving water quality even when water quality monitoring devices and drainage devices are installed in places where operation is difficult, such as inside manholes. In a case of a deviation between a manual analysis value obtained at a water quality monitoring device (water quality sensor) installation site and the water quality measurement value (e.g., residual chlorine concentration) measured by the water quality monitoring device, a calibration value obtained based on the manual analysis value is stored in a cloud database via a communication terminal (communication unit) and network, and the water quality monitoring device downloads (acquires) this calibration value, and calibrates the water quality sensor based on the calibration value. Additionally, water quality can be improved by remotely managing drainage operations and controlling the start and stop of drainage operations according to the water quality.

摘要： A device that detects the presence of surfactant residues utilizes a motion-based camphor test to detect surfactant(s) and surface-active molecules. The device, also referred to as a camphor-based dynamic tensiometer, can be used to detect desirable and/or undesirable surfactant(s). For example, surfactants used for membrane cleaning, as surface active ingredients, need to be rinse out of surfaces. Especially for porous membranes the rinsing of the Permeate side is water-intensive, since the huge membrane area of the porous structure. Thus, a camphor-based dynamic tensiometer can be automated to determine end of rinse in systems that utilize CIP chemistries containing surfactant(s). Proper rinse of CIP chemistry(ies) is key while removing the cleaning chemistry and balancing on the other hand water spent for the rinse, as membranes are difficult to rinse due to the porosity of the membrane towards the permeate site and the big inner surface of the porous structure.

摘要： Membrane filtration systems can be used to purify liquid streams for downstream use. In practice, foulant can build-up on the surface of a membrane within a filtration system over time. The effectiveness of the filtration system will deteriorate if the fouling is not properly controlled. In some examples, a method of controlling membrane fouling in a pressurized membrane system involves supplying a feed stream that is predominately air mixed with water to the membrane. In other words, the feed stream a greater volume of air than water, even though it is the water being processed by the membrane. Supplying the pressurized membrane system with a feed stream that contains a greater volume of air than water can yield significantly better performance than supplying the membrane with a feed stream that contains a greater volume of water than air.

摘要： A sensor assembly for a castable lure is provided including a pressure sensor configured to measure a water pressure applied to the castable lure when deployed in an underwater environment, a processor, and a memory including computer program code. The computer program code configured to, when executed on the processor, cause the processor to receive pressure data from the pressure sensor, correlate the pressure data with time stamp data, cause the pressure data and correlated time stamp data to be stored in the memory, determine a data connection status between a transceiver and a marine electronic device, and in response to determining that a data connection exists, cause the pressure data and the correlated time stamp data to be transmitted to the marine electronic device. The pressure data and correlated pressure data correspond to a depth profile for a cast of the castable lure.

摘要： The present invention relates to a sensor for determining the concentration of an acidic or basic compound dissolved in water, wherein the determination is based on an ingress of gas or vapor of said compound, causing a change in pH value, within an inner buffer separated from a sample side by a membrane that is permeable to gases and impermeable to ions, characterized in that a layer is provided between the membrane and the sample side, wherein the layer substantially covers the membrane, wherein the layer is water-soluble and has pH buffering properties. The present invention further relates to the use of a water-soluble layer having pH buffering properties for protecting a sensor for determining the concentration of an acidic or basic compound from ingress of an acidic or basic gas during non-use of the sensor.

摘要： The present disclosure provides a method and system for predicting effluent ammonia nitrogen (NH4—N) and an electronic device. The method includes: obtaining data to be tested; and inputting the data to be tested into a trained deep echo state network, to obtain predicted NH4—N concentration. A method for establishing the deep echo state network includes: establishing an original network, where the original network includes a plurality of input variables and reservoirs, and a principal component analysis (PCA) mapping layer is added between adjacent ones of the reservoirs; initializing the original network to obtain an initialized network; performing parameter optimization on the initialized network by a matrix generation method of singular value decomposition and a competitive swarm optimizer (CSO) algorithm, to obtain an optimized network; and training and testing the optimized network, to obtain the trained deep echo state network.

摘要： A hydrant includes a standpipe, a discharge nozzle, and a subterranean valve operated by a valve stem. The operating stem is hollow and has an inlet at its lower end and a drain outlet at its upper end, thereby providing a path to flush the sampling station when the subterranean valve is shut and the discharge nozzle and drain outlet are open by applying a differential pressure. The subterranean valve includes a cartridge having a fixed portion and a moveable portion. The fixed portion is fixed to the end of the stem and turns with it but does not move axially. The moveable portion moves axially but does not rotate. The fixed and moveable portions are connected to each other by a threaded connector. The cartridge, including a valve plug, a valve seat, and a threaded operating mechanism can be removed simply by removing a top cap on the standpipe.
