CHARACTERIZATION OF DEPOSITS FORMED IN A WATER DISTRIBUTION SYSTEM

The development of unwanted deposits in any water distribution system is unavoidable under standard conditions. Knowing the composition of such deposits will help to establish the causes of deposit formation and consequently to be able to keep water quality as high as possible. This paper presents t...
