Problems solved by technology

However, not all biocides are effective against a broad spectrum of microorganisms and / or a wide range of temperatures, and some are incompatible with other chemical treatment additives
Also, some biocides do not provide microbial control after a sufficiently long period of time
[0004] Although some of these disadvantages can be overcome by using larger amounts of biocide, such an option creates its own problems, including increased cost, increased waste, and the fact that additional biocides will interfere with the needs of the media being treated. possibility of nature
Moreover, many commercial biocidal materials do not provide effective control even when relatively large quantities of biocides are used, due to weak activity against certain types of microorganisms or the tolerance of microorganisms to these materials

Embodiment 1

[0018] Synergistic effect of TTPC and THPS against microorganisms

[0019] In this example, tributyltetradecyl chloride was tested at different concentrations (TTPC), tetrakis(hydroxymethyl)sulfuric acid (THPS), and a combination of TTPC and THPS to determine their efficacy against bacteria isolated from industrial cooling water samples. Use a final bacterial concentration of approximately 5x10 7 CFU / ml of water samples. Prepare a biocide solution and dilute it in sterile deionized water for use within 2 hours.

[0020] Time-kill tests were performed to determine the limit concentration required for biocide activity in cooling water samples. For all evaluations, tests were performed in a 96-deep well block format using a total sample volume of 600 μl. In these samples, up to 10% of the total volume consisted of biocide and organism solution, and all non-matrix additions were normalized for all samples. The 96-well block for each experiment contained biocide-treated sa...

Abstract

A biocidal composition comprising tributyl tetradecyl phosphonium chloride and tetrakis(hydroxymethyl)phosphonium sulfate at a weight ratio of 2:1 to 1:10, and its use for the control of microorganisms in aqueous and water-containing systems.

Description

technical field [0001] The present invention relates to biocidal compositions and methods of their use for controlling microorganisms in aqueous or aqueous systems. Compositions containing tributyltetradecyl chloride and tetrakis(hydroxymethyl)sulfuric acid Background technique [0002] Water systems provide fertile breeding grounds for algae, bacteria, viruses, and fungi, some of which can cause disease. This microbial contamination can create a variety of problems including loss of aesthetics such as slimy green water, various health hazards such as fungal, bacterial, or viral infections, and mechanical problems including clogging, corrosion of equipment, and reduced heat transfer. [0003] Biocides are commonly used to disinfect and control the growth of microorganisms in aqueous or aqueous systems. However, not all biocides are effective against a broad spectrum of microorganisms and / or a wide range of temperatures, and some are incompatible with other chemical tre...
