Our reverse osmosis (RO) systems deliver high-purity water for drinking and cooking in homes and businesses. RO uses a semi-permeable membrane to remove dissolved salts, minerals and contaminants from water. Intergulf provides turnkey RO installations – from under-sink units to whole-building filtration – ensuring reliable supply of safe, potable water. These systems protect health and equipment by filtering out impurities, and our service programs ensure they stay efficient and trouble-free.
