From sea to lab= how to ensure CLEAN sea water
The sea waters is prefiltered using a 60 cm high, 2 mm mesh size water strainer positioned at the inlet of the pumping. Pipes are made from polypropylene.
The hydraulic systems inside the laboratory is cleaned twice a month chemically with ~1% H2O2 for 4 hours, and outside with high pressure fresh water by using a special pipe cleaning nozzles that blast the dirt out of the pipes.
