Title: Improvements in or relating to the control of iron bacteria
Inventor: BUCKMAN STANLEY J
IPC: D21C9/00
Filed: 1957-10-28
Abstract: The growth of slime-forming iron bacteria, e.g. Sphaerotilus natans in industrial water is controlled by the use of one or more water-soluble salts of N-monoalkyl-substituted dithiocarbamic acids the alkyl radical(s) of which contain less than 4 carbon atoms.  The salts may be used in conjunction with one or more other toxicants having a greater effectiveness against slime-forming micro-organisms other than iron bacteria e.g. one or more water-soluble salts of cyanodithio imidocarbonic acid (for controlling species of Aerobacter and Pseudomonas); ortho-phenyl phenol; 2, 4, 6-trichlorophenol and other polychlorophenols.  The two kinds of toxicants may be added to the water together in concentrated aqueous solution, or they may be added separately, preferably first controlling iron bacteria by addition of N-monoalkyl-substituted dithiocarbamates and subsequently adding the cyanodithioimidocarbonates or other toxicants.  Where other toxicants are employed which do not form concentrated aqueous solutions with N-monoalkyl-substituted dithiocarbamates, e.g. organomercury and organotin compounds and inorganic or organic compounds of copper, the toxicants are added individually in solution or as solids, or in combination as solids or suspenisons in water or other liquid.  A preferred composition is an aqueous solution of a mixture of potassium N-methylditriocarbamate, sodium cyanodithioimidocarbonate and ethylenediamine in percentage proportions by weight of 18,0, 13,1 and 4,9.  The alkyl-substituted dithiocarbamates are added as 0,1 to 20 parts per million of water. Specification 809,351 is referred to.
