Mactan Rock Industries Inc (MRII) Chairman Antonio Tampar reported a 60% increase in the consumption of desalinated water in Cebu. The largest consumer are hotels malls and industrials. They set up the largest desalination plant in the country with Pilipinas Water Resources. Their plant is capable of supplying 22,000 cubic meters of desalinated water a day. It promises to be back up for adequate water supply in case of shortage.
Desalination processes brackish or sea water by either thermal or reverse osmosis process (the sea water is pumped at high pressure at 1,000 psi through polyester membrane which causes brine to separate from fresh pure water. This means desalination is an energy intensive process and makes the water from desalination costlier than fresh unprocessed water from water districts.
MRII has 50 outlets nationwide which means desalination is accepted in the country now.
They build and supply filtration aside from SWRO. They have BOOM scheme. Build Own, Operate and Manage
