What this video covers
Ivo installs and demonstrates a Rainman portable watermaker aboard Silkap, walking through the full plumbing setup and a live production run. The system draws seawater through a deck-dropped intake hose, passes it through a 5-micron pre-filter that removes bacteria and particulates, then forces it through membranes under high pressure via a black high-pressure hose.1:43 The membranes separate fresh water from brine; the brine exits overboard through a green hose, and fresh water routes through a white hose to the port-side tank.3:09 At startup, Ivo adjusts pressure to reach the rated 140 litres per hour, noting that lower salinity water requires less pressure.3:28 A TDS meter reads 173 particles per million against a 600-particle maximum, confirming excellent output quality.4:44 He fills a bucket of produced water first to use for flushing and purging the system at shutdown — a required maintenance step.4:18 After one hour the port tank receives roughly 140 litres.4:55 Ivo and Dajana taste the concentrated brine reject stream and debate whether its cleaner-than-seawater quality makes it usable for cooking pasta, concluding it is too concentrated without dilution.7:17
