Calcium carbonate (EWT)
EWT is a harmless granular alkaline filter material with a high purity of calcium carbonate. Because of its microcrystalline structure, it is superior to ordinary limestone.
EWT compound is highly suitable as media for neutralizing/mineralizing filters installed after the RO watermaker or evaporator. The compound will re-harden and neutralize corrosive product water, resulting in protection of the piping and installations against corrosion. It will also improve the taste and appearance of the water. The EWT Compound reacts by slowly dissolving in the water.
