Greencastle Technology Ltd supply range of Deionisation (DI) Cylinders complete with mixed bed resin which can be standard or nuclear grade. A cylinder refill service is available and we can supply resin in 25ls bags to allow the client to refill the cylinder.
Mixed bed resin functions by exchanging hydrogen ions for cationic contaminants & hydroxyl ions for anionic contaminants in the feedwater supply.
Feedwater passes through the resin & after a period of time, cations & anions will replace most of the active hydrogen & hydroxyl sites in the resin. Resin capacity to remove ions will have been reached & will need to be replaced.
Greencastle Technology Ltd supply a range of Carbon Cylinders complete with various types of carbon media depending on application. A cylinder re-fill service is available and we can supply media in 50ls bags to allow the client to refill the cylinder.
Granular Activated Carbon (GAC) filters are an excellent choice for removal of chlorine, taste & odour, or organics in water. There are many different variations but most are either coconut coal or wood based. As water travels through the media the contaminants are adsorbed onto the carbon & after a period of time the media will need to be replaced.
