Webbsludge deposits that precipitated elsewhere and were transported to the metal surface by the flowing water; Scale is formed by salts that have limited solubility but are not totally insoluble in boiler water. These salts reach the deposit site in a soluble form and precipitate when concentrated by evaporation. WebbFormation of deposits: Scale and sludge formation. Scale:If the precipitate forms hard and adherent coating on the inner walls of the boiler is known as scale. It is formed by the substances like CaSO4, Mg (OH)2 and Ca (HCO3)2. Scales are difficult to remove even with the help of hammer and chisel. Scales are the main sources of boiler troubles.
WebbThe ammonium adsorption properties of aerobic granular sludge, activated sludge and anammox granules have been investigated in Chapter 2. During operation of a pilot-scale aerobic granular sludge reactor, a positive relation between the ammonium influent concentration and the ammonium adsorbed was observed.
