SEA WATER DESALINATION<br />
SUCCESSFUL COMMISSIONING OF DESALINATION PLANT<br />
IN GRESIK SMELTER AND REFINERY<br />
Reverse osmosis (RO) is proved to be the most reliable, cost effective, and energy efficient in producing fresh water compared<br />
to other desalination technologies. In 2017, Enerba has successfully commissioned the desalination plant in PT Smelting, Gresik<br />
Smelter & Refinery. The plant is utilizing <strong>SWRO</strong> technology. The product of desalinated water further be treated through BWRO<br />
system to produce of permeate water for boiler and process water application.<br />
The Enerba <strong>SWRO</strong> system consist of 165 m 3 /hour pretreatment plant comprising<br />
of Lamella clarifier followed by 3-stage filtration using Sand Filter, Manganese Filter<br />
and Carbon Filter.<br />

SCADA stands for Supervisory<br />
Control and Data Acquisition. The<br />
SCADA system is computer-based<br />
simulation, which monitor data<br />
hourly. It is used for data acquisition<br />
and controls of the plant variables<br />
such as temperature, pH and<br />
pressure. The most important control<br />
variables for a <strong>SWRO</strong> plant are flow,<br />
pressure & conductivity.<br />
Laboratory Scale Capacity 10L - 100L<br />
Enerba has developed a unique<br />
operation system that uses its own<br />
hardware and software products for a<br />
distributed control system (DCS),<br />
enabling automatic start-up/<br />
