Ion Exchange (India) Limited pioneered water treatment in India and is today the country's leading water and environmental management company, with a strong global presence. With 59 years of experience, we are among the few companies worldwide with a complete range of technologies, processes, products and services that cater to all sectors - industrial, institutional, municipal and domestic - urban and rural.
In 1978, Ion Exchange was the first company in India to apply reverse osmosis technology as a complementary technology to the ion exchange process for water treatment.

The company in 1987, recognized the potential of the membrane separation and purification process for industrial and domestic application and pioneered the manufacture of reverse osmosis membranes in India, establishing a state of the art membrane element manufacturing unit in Gujarat-India. Since then, under the Hydramem brand, we have offered a wide range of membrane elements for industrial, institutional and domestic applications.

We have a complete range of products:


HYDRAMEM RO membranes are composed of fully aromatic cross-linked polyamide (thin film) and are widely offered in four categories: low pressure, brackish water, fouling-resistant membrane and seawater elements.

LOW PRESSURE RO MEMBRANES (industry):

BRACKISH WATER RO MEMBRANES (industry):
