Common failures & inspection points

Vacuum system failure or degradation

Verify vacuum gauge reading minimum 90% vacuum; standard vacuum generation time approximately 10 minutes from cold start

Scale formation on evaporator plates reducing heat transfer efficiency

Inspect heat exchanger plates for mineral deposits (calcium carbonate, magnesium hydroxide, calcium sulphate) via demister removal; perform chemical descaling per manufacturer schedule based on fouling rate

Elevated salinity in produced fresh water (brine carryover)

Monitor salinometer reading; check ejector nozzle condition and brine extraction pump operation; ensure brine level is maintained correctly

Evaporator coating damage or internal tube corrosion

Remove separator shell man-hole cover and heat exchanger bottom cover for visual inspection; verify Neoprene coating integrity; check for exfoliation; inspect condenser cooling tubes for sludge fouling

Evaporation temperature excursion (risk of scale acceleration)

Check thermometer on separator shell after 15-30 minutes of steady operation; maintain lowest safe evaporation temperature to minimize scale formation risk without compromising salinity
