Water used in the preparation of 1.0 N NaOH
before prepare standard solution it is to use plain RO water may be potential of the biofilm.
Because the water in the tank for a long time
in the present experiments. During a water boil. Prepared using the conventional RO water was
not precipitate out of the water from boiling. We have solved this problem since 10/2014
** And yet, when previously not as sludge because of the quality of water used in the operation may vary according to the time , even though the water is no heavy metals. contamination of water, but If the water contains organic substances in the water can cause mold in water
Further experimental and For titration .Although it does not eliminate sludge and biofilm out.
It can also analyze the results are the same. No problems found by the mismatch.
Note :
** Biofilm refers to a variety of microbes trapped in the mucus layer and organic substance that sticks to the surface of the pump casing wall and more.
