A » Brackish water reverse osmosis (RO) systems are designed to treat water with lower salinity levels than seawater, typically ranging from 1,000 to 10,000 ppm. Seawater RO systems handle higher salinity, around 35,000 ppm. Consequently, seawater RO requires more robust membranes and higher pressure to overcome osmotic pressure, thus making it more energy-intensive and costly compared to brackish water RO systems.

A »Brackish water RO systems are designed for water with 1,000-10,000 ppm salinity, while seawater RO systems handle higher salinity levels, typically above 30,000 ppm. The main difference lies in their membrane design and operating pressure, with seawater RO requiring higher pressure to overcome osmotic pressure and achieve effective desalination.
