As hellosailor noted, the Watermaker manufacturer will provide detailed instructions for recommissioning your particular unit.
Recommissioning a watermaker, generally consists of:
Flushing the system to remove biocide, measuring the output flow of fresh water, and finally testing* output quality ~ measuring the salt (Total Dissolved Solids).
* TDS Meters & Water Test Kits are available from your watermaker supplier, or:
** Common Pathogens:
is about 0.001microns, which is your expected R/O filtration size.
Protozoa cysts range is size from 2 to 15 microns (a micron is one millionth of a meter).
Pathogenic bacteria range in size from 0.2 to 0.6 microns.
Most pathogenic viruses range in size from 0.020-0.030 microns, and are too small to be filtered out by a mechanical filter.
Although an R/O unit will remove virtually all pathogens from drinking water
, it’s not recommended for this primary use; as bacteria can form a slimy coating on the membrane, preventing the proper flow of water through it.
Estimates for membrane life vary. Every precaution should be taken to prevent chlorine & petroleum products from contacting the membrane as they will damage or destroy the membrane. The prefilter must also be regularly changed, and the membrane may need to be treated with a biocide occasionally. The water produced by reverse osmosis
, like distilled water, will be close to pure H2O. Although most of the minerals that we receive are from the foods we eat, not our drinking water
; some authorities recommend that mineral intake may need to be increased to compensate for the mineral content of “normal” drinking water.
