High salinity wastewater treatment. The shock effect, survival and ability of activated sludge to acclimatize to wastewater containing different concentrations of NaCl and Na2SO4 were investigated under laboratory conditions. To accomplish this, the potential penetration of a sewage system by seawater as a consequence of storm surge f ….

Sodium sulphite is frequently used for removal of traces of oxygen from boilerfeedwater. It can be used in marine boilers operating at pressures up to 40bar. Catalysed sodium sulphite is used in most cases, as the reaction time withoxygen is extremely fast even at ambient temperature.
Steam purity can be measured with the use of a sodium ion analyzer. It measures the sodium ion content in a cooled steam sample that will correspond to the amount of boiler water solids contaminating the steam. The sodium ion analyzer can detect carryover down to 1 ppb sodium in steam. …
(A) Scale forming salts present in sea water and harbour water, which can enter the boiler feed water system by carry-over of salty moisture with the vapour from the evaporating plant, by salt water leakage from evaporators into the condensed steam in the evaporator heating coils, by salt water leaks in condensers, through leaky bottom blow valves in idle boilers.

May 02, 2000 · softeners they are regenerated with salt and often a combination of salt and sodium hydroxide. Dealkalizers exchange undesirable negatively charged ions mostly carbonates for desirable ions mostly chloride and some hydroxide. Carbonates break down in boilers to form carbon dioxide, which carries off with the steam. Carbon dioxide becomes very
