摘要:

An ODED or a ZEDED sequence bleached kraft hardwood and softwood pulps to 87 — 89‰ ISO brightness. The bleached yields were similar for a given pulp, whether oxygen or ozone was used in the first stage. The strength properties of the fully bleached pulps were essentially the same as those of the unbleached pulps. The COD and colour values of the effluents after ozone delignification and subsequent extraction were 25‰ and 60‰ lower, respectively, than those of the effluents after an oxygen treatment.

摘要:

A Mexican company plans to sell artificially cultured and cleansed adult scallops, Argopecten circularis, to Mexicans and Europeans for human consumption. A series of six experiments, comparing the effectiveness of ozone vs chlorine depuration in adult A. circularis, was performed at the aquaculture facility in La Paz. It was quite difficult to maintain oxidant residuals due to the extreme ambient temperature (+42˚C), but experiments did show that both oxidants, chlorine and ozone, reduced total plate count 90–94‰ and chlorine treatment depurated scallops of coliform in the experimental treatment time.
