The invention relates to a method and a system for treatment of an underwater surface (S) and material removed from it at a cleaning site. The underwater surface is cleaned by a brush device (1), by which effluent containing solid matter removed from the underwater surface in connection with cleaning is conveyed to a treatment unit (5) where the effluent is subjected to separation and filtering. In a first step, the solid matter contained in the effluent is separated from the effluent in a form as unbroken as possible, immediately followed by a second step in which the effluent is precipitated. Said second step is immediately followed by a third step in which the effluent is filtered. The filtered effluent is discharged directly back to a body of water or to another clean water connection at the cleaning site. The effluent may be subjected to additional filtering and/or disinfection, if necessary.

A sterilizing device includes a pipe having an inlet and an outlet and allowing fluid to move therethrough and a light source provided on one side of the pipe and providing light to the fluid. At least a portion of the pipe is provided in a spiral shape and the inlet and/or the outlet are arranged in a light emitting region.

A water delivery control system operates to selectively deliver water from a water source to water use devices. The system includes a master controller that wirelessly communicates messages with a plurality of slave controllers. The system includes a valve slave controller associated with a water control valve and a motor that is operative to selectively move at least one valve element of the valve. A water meter is operative to measure water flow that corresponds to flow through the valve. The master controller is operable to cause the valve slave controller to enable or prevent flow through the valve responsive at least in part to water flow data. The controller is operative to determine a water use condition responsive to a water usage pattern, and to cause at least one message to be sent to a portable user device responsive to the determined water use condition. The user interface slave controller is associated with a user interface.

A process for batch processing by-product water to obtain a batch of beneficial use water for application to an targeted area of soil with determined moisture and chemical characteristic to change that soil characteristic to a desired soil characteristic includes the steps of measuring the moisture and chemical composition of the targeted area of soil; determining a desired soil characteristic that will grow selected vegetation; defining a chemical composition of a batch water to be applied to the soil to obtain the desired composition; processing a batch of by-product water in accordance with the defined composition; applying the batch of processed water to the targeted area of soil; measuring the moisture and chemical composition of the soil after application; repeating the process until desired composition is achieved or the vegetation growth is completed.

Provided are a system for monitoring a hydroxyl radical scavenging index in water using a real-time multi-fluorescence analyzer and a parallel factor analysis apparatus and a method therefor, wherein the system monitors the hydroxyl radical scavenging index in water using the real-time multi-fluorescence analyzer and the parallel factor analysis apparatus, whereby it is possible to monitor the characteristics of an organic material in target water through a continuous flow analysis method without using an existing indicator material, rhodamine B. In addition, in a water treatment system having an advanced oxidation process (AOP) applied thereto in which ozone, ultraviolet rays, hydrogen peroxide, and the like are combined, it is possible to simply calculate the hydroxyl radical scavenging index in the target water through an organic material characteristic index for each component obtained by classifying the characteristic structure of the organic material in water using real-time fluorescence analysis by means of a parallel factor (PARAFAC) model. Accordingly, the amount of chemical injection and the amount of ultraviolet irradiation, which are process control variables, can be controlled, and under given operating variable conditions, the removal rate of a target material in water is predicted, whereby the system can also be used as a diagnostic tool for process evaluation in the advanced oxidation process. Furthermore, the system can provide operational convenience that enables process control while reducing the amount of power consumed in the advanced oxidation process even though the type of target material and the water quality characteristics of raw water change.
