PACT desalination plants treat brackish and
high brackish well-water sources as well as seawater sources
ranging from 30,000-45,000 mg/l TDS. Standard capacities manufactured
by PACT cover few cubic meters per day up to 1000 m 3 /day.
Custom-built systems up to the tens of thousand of m 3 /day
are designed in-house and built to the most stringent specifications.
Making use of high grade SS alloys for protection against
aggressive marine environment as well as state-of-the-art
energy recovery equipment for the most efficient use of energy
(energy is the single most expensive item in cost of water
desalination).
