✦ Synopsis

Among the "seeding" processes which reduce or ell$nate the risk of scaling, in sea water evaporators. the barium sulfate seeding process "BSS" has been reported to possess the special odvartage of reducing the calcium concentration of the circulated brine in a multi-stage flash evaporator with brine recirculation. Using a simple mathematical model. this Ca-diminution is made understandable. Two examples are calculated based on a BSS plant feasibility study published elsewhere*: the results are Ca-diminution by the factors 0.73 and 0.56 in a stationary state, which is reached after about ten times the theoretical trawl time of one fluid element along the brine circulstion path.
