Specifications include, but are not limited to: Purpose of the project is to replace the 2 existing Portacel Evaporator units. The units are no longer supported and parts are getting very difficult to obtain. Water Treatment Disinfection require a continuous supply of Chlorine gas applied at the Contact Basin. Purchasing two new units of an approved and reliable source will make sure the Water Treatment Plant can continue to meet water quality standard for system disinfection. Both new units must be a matching set of a complete Chlorine Evaporation System. Designed as a heat exchange unit when large quantities of chlorine gas is required for disinfection. The Evaporator units receive pressurized Liquide Chorine from the storage vessel to convert into a gaseous form. Utilizing this method, greater quantities of gas can be made available than would be possible if gas is drawn directly from the storage vessel. Allowing the Water Treatment plant to meet treatment standards through any seasonal weather condition or water treatment demands.
