摘要： Systems and methods that enable the responsive treatment of a body of water with an aqueous halogen solution whose composition can be varied as a result of input from sensors monitoring the water being treated. Various sensors are immersed in the water so that the physical, chemical, and microbiological properties of a body of water being treated can be measured. Information from these sensors is used to produce aqueous halogen solutions of varying composition which are then injected into the body of water being monitored for the purposes of ensuring the body of water being treated is being effectively disinfected.

摘要： Methods are described for monitoring biofouling in a closed water system. For example, a method includes adding nitrate to water circulating in the closed water system, and detecting whether nitrite is present in the water after adding the nitrate. Another method includes introducing chlorite into water circulating in the closed water system, the detecting the amount of chlorite present in the water; and at least one of (i) comparing the detected amount of chlorite to an expected amount of chlorite; and (ii) observing whether the amount of chlorite in the water decreases over time.

摘要： Chemical testing devices, chemical dosing devices, and combined chemical testing and dosing devices are disclosed for testing central heating or cooling system water for a level of chemical inhibitor. An example dosing device (10) has a reservoir (12) for holding a supply of chemical, which can be added by opening removable closure (16). The reservoir (12) is connected to an interface (26) via a valve (40). The valve can be opened to allow exchange of fluid between the central heating or cooling system circuit and the reservoir (12).

摘要： The present invention relates to a cartridge member (10) for an apparatus (100) for dosing salts for a hydraulic system, wherein the dosing apparatus (100) comprises a connection member (20) having a first connector (21), a second connector (22) and a coupling collar (23) in fluid communication either with said first connector (21) and/or with said second connector (22), and a container member (30) which can be coupled with said connection member (20) so as to delimit, together with the latter, an internal compartment (V) into which said coupling collar (23) faces. The cartridge member (10, 210) comprises a tubular external wall (11) which delimits internally an operating chamber (11c) and which defines together with the container member (30) a cavity (I) outside said external wall (11). The operating chamber (11c) is divided up by a separation wall (12) into a first chamber (13) and a second chamber (14) configured to contain salts to be dosed and has at least a first passage section (15) which places said first chamber (13) in fluid communication with said second chamber (14) and a second passage section (16) which places said second chamber (14) in fluid communication with said first chamber (13) or said second chamber (14) with the cavity (I). The cartridge member (10, 210) also comprises pressure- reducing means (18a, 18b, 110) designed to induce a pressure drop in a liquid which crosses them.
