Abstract

Fresh water generator is one of the machines on board that serves to convert seawater to fresh water by distillation in a maximum state. The working principle of the fresh water generator is to separate the salt content in seawater by evaporating it in a vacuum so that the boiling point decreases and seawater at a temperature of 100C. Problems with the fresh water generator will affect the amount of fresh water production that is not optimal, such as low air pressure from the ejector pump causing clogged filters on the suction ejector pump so that the production of fresh water on the fresh water generator decreases and knowing the cause of clogged filter ejector pumps caused by dirt that has accumulated in the fresh water generator. filters and mechanical seal leaks caused by lack of maintenance. The second problem is the emergence of crusts on the outside of the evaporator pipe causing the heat absorption to be not optimal to produce a clean water generator, so the way to overcome it is by using chemicals such as (chemical dosing ameroyl) or treatment methods to remove crusts such as brushing and soaking. The results, after knowing the cause and immediately carrying out treatment, the ejector pump obtained normal and good sea air pressure so that sea air can circulate properly. Then after treatment with the chemical method the scale on the evaporator plate has been reduced so that the heat transfer process can be perfect. Keywords: fresh water generator, reduced fresh water production and maintenance
