WebFlocculation experiments using aluminum sulfate and sodium chloride as coagulant and flocculant, respectively, reduced concentrations of Cr 6+ to 5.01 g m −3. This degree of reduction is highly unsatisfactorily, However, after a batch treatment with activated-carbon the concentration of Cr 6+ could be reduced to 2.77 g m −3 [39]. WebARL has observed sterility failures due to multiple causes. In one instance, a “not sterile” result was invalidated due to a cracked filter container. The growth media used to test a Vancomycin product for sterility was turbid at the 14 day observation point, and, upon further examination of the media container, a crack was discovered.
