Reverse osmosis plants(RO Plant) require pre-treatment to minimize energy requirements. These include softening, dechlorination, and anti-silent treatment of the water. High levels of pressure send the water through a semipermeable membrane, which retains all contaminants but lets pure water pass through.

Reverse Osmosis plant(RO Plant) is a common process to purify or desalinate contaminated water by forcing water through a membrane. Water produced by RO Plant may be used for a variety of purposes, including desalination, wastewater treatment, concentration of contaminants, and the reclamation of dissolved minerals.

Solar reverse osmosis systems are a new concept in Indian water purification industry. In such water purification systems, solar energy is utilized to power ro systems, which furthermore; generate clean water for drinking purpose. These solar ro water systems can purify water from any source. Water from river, pond or bore well, these solar ro systems can deliver safe drinking water anywhere you need; in addition, these systems are highly suitable for military camps, village areas and fairs and tourist places where arrangement of temporary drinking water is a prime requisite at minimal price.
