GEA designed and built eight (8) drinking water RO plants for domestic use in Chennai and Gujarat, which have been experiencing serious drought conditions for the past 3 years. These residential private plants range from 2,000 to 15,000 GPD, typically averaging about 12,500 GPD. Source water is marginal or unsuitable ground or river water.
Most systems have had a two-pass design to achieve recoveries of 80% with typical influent TDS ranging from 2,500 to 4,000 ppm. Permeate quality drinking water is less than 75 ppm TDS and meets WHO drinking water standards.
