Water is then pumped up to the trailer, passed through an ultra filter and the filtrate is then liquated to the sample lines, which are plumbed to the instruments. The water is pumped through the sample hose to the trailer and passed through a spaghetti-like ultra filter, which filters out any particulate matter bigger than .02 microns. Once this happens the filtered sample or filtrate is then pumped to the instruments for analysis. Filtrates are liquids that have passed through filters, which separates particulate matter depending on the pore size of the filter. The user could either raise the pump and clean underneath the pump housing or either force compressed air through the sample hose back towards the pump.
Instruments stop working because reagents are empty.
Strange analysis readings from the instrumentation. Their may be air bubbles in the lines so the user should put the instrument into maintenance mode and prime the lines.
