Remediating biofouling of reverse osmosis membranes
Several potential additives and the use of influent pH adjustment were examined to remediated the biofouling problem of the ETF reverse osmosis (RO) system. Tests were conducted with simulated RO feed containing salt, metal hydroxides and bacteria. The addition of sodium hexametaphosphate (SHMP), sodium bisulfite, and adjusting the influent pH to 3 were each successful in reducing the RO biofouling. Little or no benefit was found from the use of a biofilm remover (Filmtec Alkaline Cleaner) or the use of surfactants (Surfynol or sodium lauryl sulfate). In addition, Surfynol use resulted in irreversible fouling and necessitated membrane replacement. At the water recoveries used in the ETF (>90%), sodium bisulfite addition resulted in the recovery of 70--90% of the flux and almost complete restoration of the DF to prefouled conditions. Based on the bench-scale tests completed, IWT would recommend that sodium bisulfite addition be tested at the ETF. This testing would involve optimizing the amount of bisulfite required. In addition, it is recommended that the addition of SHMP or influent pH adjustment be evaluated since the relative differences in labscale tests were small and scale-up effects could be present. The ETF operating permit allows each to be added.

Control Class Summaries and Control Class IV from April 1990
The D0 cryogenic control system is a complicated system with many facets. Because of the large number and variety of features in the system, a series of ongoing control system training seminars, or control classes, were created in order to keep people up to date on the operation of the system. As of the writing of this engineering note, there have been four classes. The original lecture notes from each class can be found in the cryogenic control room at the D0 Assembly Building, or in the Co-op office. This note provides a summary of the first three control classes, and it includes the entire set of notes from the fourth class, which was held in April of 1990. This class was taught by Jeff Wendlandt and Dan Markley. Dan should be consulted for more complete explanations than those given in the notes. The notes are, in fact, more of a reference for someone who has some experience with the system, than they are a training manual. Most of the pages include pictures and printouts of different menus and functions, useful for finding details without searching through the actual program. In general, this note serves as a pointer to the …

COUPON IMMERSION TESTING IN SIMULATED HAZARDOUS LOW LEVEL WASTE
AISI Type 304L (304L) stainless steel was recommended as a suitable material of construction for the new Hazardous Low Level Waste Processing Tanks (HLLWPT). This report documents the second phase of a coupon immersion test program to determine the susceptibility of 304L to localized attack in a variety of simulated wastes. The coupon test results confirmed the conclusions that were made from the first phase of the test program. First, 304L is a suitable material of construction for the new waste tanks. Second, the agreement between the cyclic polarization tests and the coupon immersion tests demonstrates that cyclic polarization can be used to predict the susceptibility of a material to localized corrosion in these wastes. In addition to the tests performed on 304L, tests were performed on ASTM A537 carbon steel (A537) and Incoloy 825 (I825). Neither 304L nor I825 was susceptible to attack, while A537 experienced varying degrees of attack in the different wastes. Observations on the surface attack and corrosion products on A537 were used to elucidate the mechanism by which A537 corrodes in these wastes.
