From water-makers to industrial sized Seawater Purification, we offer a full range of systems.


Our units are manufactured to eliminate a large amount of salts and other minerals from seawater using RO. Our equipment does the filtration by employing a high-pressure pump to salty water forcing it through semi-porous membranes denying salts and other organics from flowing through.


The membranes are only tasked to remove dissolved solids while dividing the feed water into purified water and rejected concentrated salts.  The salts and other organics are thrown into the brine stream then flushed into a drain. At the end we have purified water that has 99% less dissolved salts. These sea water RO systems have the power to purify extremely high TDS water.
