The brand is known for its full-flow electrolytic system operating only during ballasting. Erma First fit BWTS operates during ballasting and as the de-ballasting process is taking place, acts as a monitoring unit. Its function during the two steps is described below.
Ballasting
At this stage, water filtration happens. Any object with a diameter of more than 40 microns is eliminated from the water. Then the filtered water enters the electrolytic cell, where the chlorine is produced through the electrolysis process out of the chloride existing in the water. The chlorine concentration is very low about 4 to 6 milligrams per liter.
De-ballasting
The system acts as a monitor agent for residual oxidants during the process. There is a sensor for assessing chlorine amounts in discharge water. If the Total Residual Oxidants (TRO) sensor determines there are more than 0.1 milligrams of chlorine per one liter of water, the dosing pump releases sodium bisulfate as a neutralizing agent to create the doe balance. In the end, by the approval of a secondary TRO sensor located at the endpoint of the ballast line, the water will discharge.
