Corrosion and contamination preventing apparatus and subsystem for watermaker systems

摘要

A corrosion and contamination preventing apparatus and subsystem including a conduit forming a watermaker flush-water flow path between a potable water supply and a feed water entry portion of a watermaker system, a filter/ion-generator component disposed along the flush-water flow path, a valve means for opening and closing the flush-water flow path, and a controller for sensing flush-water flow in the flow path, and in response thereto applying electrical power to an ion-generating element of the filter/ion-generator component. The filter/ion-generator component also includes a filter which filters undesirable chemicals from the potable water before the ion-generating element introduces copper and/or silver ions into the flush-water. The valve means may be manually operated or be controlled by a watermaker system shut down controller.

1. A corrosion and contamination preventing subsystem for introducing decontaminating flush water into the operative flow path of a desalinating watermaker system during system shut down, comprising:
a conduit forming a flush water flow path between a potable water supply and a feed water entry portion of the operative flow path of the watermaker system, a valve means operatively disposed along said conduit for selectively opening and closing the flush water flow path, a filter/ion-generator component operatively disposed along the flush water flow path and including an ion-generator element for generating copper and/or silver ions for introduction into flush water flowing through said conduit when said valve means is in its open state; and a controller means for sensing flush water flowing through said conduit when said valve means is in its open state, and in response thereto applying electrical power to the ion-generator element, whereby when the watermaker system is in a shut down mode, and said valve means is in its open state, said controller means senses the flush water flow through said conduit and applies power to said ion-generator element causing it to introduce copper and/or silver ions into the flush water as the flush water flows into the operative flow path of the watermaker system to kill contaminants therein.
