  • Publication number: 20200238887
    Abstract: A trailer for transporting a liquid mixture having at least about 5% peracetic acid by weight includes a stainless steel tank having an external spill containment enclosure and a predetermined maximum allowable working pressure. One or more pressure relief valves are included in a wall of the tank within the external spill containment enclosure and configured to provide pressure relief to the tank at a pressure of between about 20%-50% of the maximum working pressure of the tank, thereby preventing over-pressurization of a reactive and decomposing fluid during a fire event. Wheels and a kingpin are affixed to the tank to enable transportation over public roadways.

  • Publication number: 20190388574
    Abstract: Provided herein are methods and compositions for sterilizing a material with a composition comprising peracetic acid and a short chain organic acid stabilizer, for example, oxalic acid or malonic acid. The use of the short chain organic acid stabilizer results in a reduction of the amount of residue deposited on the heating surface used to vaporize the peracetic acid.

  • Publication number: 20190248679
    Abstract: Provided herein are methods and compositions for reducing the level of a cyanotoxin in cyanotoxin contaminated-water. The electrolytic destruction methods can include contacting the contaminated water with an electrochemical cell in the presence of a magnesium salt and applying an electrical current to the water for a time and in an amount sufficient to oxidize the cyanotoxin. The methods are useful for treatment of lake water, reservoir water, pond water, river water, or irrigation water and any water that serves as a source of drinking water.

  • Publication number: 20180271090
    Abstract: A method of sterilizing a material, said method comprising the steps of: a) providing a sterilizing composition comprising (i) peracetic acid and (ii) a stabilizer selected from the group consisting of citric acid, isocitric acid, aconitic acid and propane-1,2,3-tricarboxylic acid; b) introducing such sterilizing composition into a hot gaseous stream to produce a peracetic acid vapor; and c) contacting such peracetic acid vapor with the material to be sterilized. The use of such an organic acid stabilizer results in an unexpected reduction in the amount of residue deposited on the heating surface employed to vaporize the sterilizing composition.

  • Publication number: 20170313604
    Abstract: Provided herein are methods of reducing microbial concentrations in water with a peracid disinfectant. The method can include the steps of measuring the quality of the water in real-time and dosing the water with a first dose of a peracid disinfectant; measuring the peracid disinfectant demand; and adding one or more subsequent doses of the peracid disinfectant. The subsequent peracid disinfectant dose can be controlled by a processor-based controller based on peracid disinfectant demand.
