APPARATUS AND PROCESS FOR WATER CONDITIONING

A conditioning process and equipment are provided for removing hardness from water circulated in a system, such as an evaporative cooling system. A sidestream from such system is routed to a reaction chamber and back to the system. A conditioner is added to the sidestream before entering the reaction chamber and a buffer is added to the sidestream exiting the reaction chamber. Since some of the buffered sidestream is re-circulated, a fluid bed develops in the reaction chamber consisting of conditioner, buffer, precipitated solids and sidestream water. Continued sidestream water entry mixes with the fluid bed causing additional precipitation of solids. An upper outlet on the reaction chamber regulates the height of the fluid bed, and a drain provides for periodic discharge of the lower fluid bed. In another embodiment, a corrosion inhibitor blend is pre-mixed with the buffer, resulting in a softer, more readily drainable fluid bed.

Method and system for distilling water

Water, e.g. sea water, which is to be distilled is first treated with a water-soluble polyphosphate and then heated, after which an acid (or a salt which forms acid on hydrolysis) is added to the water before it is introduced into the still, e.g. a vapour-compression still provided with a de-aerator. Suitable polyphosphates are:-tetrasodium pyrophosphate, sodium tripolyphosphate, and sodium hexametaphosphate. In the case of sea water, 0.5 to 10 parts of polyphosphate are added per million parts of feed water. After addition of the polyphosphate, the feed water is divided into two streams, one of which is heated by passing it in heat-exchange with the distillate, while the other stream is heated in heat-exchange with the brine blowdown. The two streams, which leave the heat-exchangers at a temperature of about 190 DEG F., are then reunited, and the acid substance is added. Suitable acid substances are:-sulphuric, hydrochloric, phosphoric, nitric, sulphamic and citric acids, sodium bisulphate, ferric chloride, and aluminium sulphate. The acidified acid is then passed, via a de-aerator, into the still. The pH of the brine withdrawn from the still is continuously checked by an instrument which automatically controls the acid addition to the feed to maintain the brine at a pH of 7.0 to 7.4. The pH of the distillate may be adjusted, as desired, with acid or alkali. The distillate may also be treated with chlorine-water.

本发明实施例涉及卫浴技术领域,公开了一种阻垢滤芯的制作方法、阻垢滤芯、过滤器及用水系统。其中，所述阻垢滤芯的制作方法包括：步骤一，将重量比为30％至60％的粘合剂颗粒与重量比为5％至20％的阻垢剂颗粒混合第一时间，得到第一混合物；步骤二，在第一混合物中加入重量比为30％至60％的过滤性颗粒混合第二时间，得到第二混合物；步骤三，将第二混合物倒入烧结模具中，进行成型和烧结，得到阻垢滤芯。通过所述阻垢滤芯的制作方法制得的阻垢滤芯可具有过滤杂质性能和硬水离子阻垢性能。通过上述方式，本发明实施例的阻垢滤芯、过滤器及用水系统结构简单，兼具杂质截留和硬水离子阻垢功能，组装和使用方便。

Salts dosing apparatus for a hydraulic system

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.
