Abstract: A clustered creature exterminating method efficiently exterminates clustered creature such as cyanobacteria in large quantity with use of a pressure which is substantially lower than that of the conventional method. The exterminating method includes the steps of: pressurizing a fluid containing a clustered creature such as cyanobacteria through a pump; suddenly lowering the pressure applied to the fluid by injecting the fluid from nozzle groups; and destroying a bonding in the clustered creature by a cavitation caused by the pressure drop. The nozzle groups may be arranged to oppose to one another to collide the injected fluids with each other, which divides the cyanobacteria into many small pieces. As a result, the cyanobacteria lose the ability to rise, and sink at the bottom of water, therefore, die because they cannot photosynthesize.

Abstract: This invention deals with a process for treating and sanitizing animal habitats. In addition to sanitizing the habitat the production of ammonia and odor from fecal matter and urine is inhibited or terminated. In the process an animal habitat is cleaned and subsequently treated with trichlormelamine (TCM). The TCM may be applied by spraying the habitat with a solution of TCM, by dusting the habitat with powdered TCM or by treating bedding/litter with TCM. This process produces healthier animals and as such the productivity of a given grow out is increased. The process of this invention is particularly suited to animal habitats which are used to raise batches of hogs, cattle, turkeys and chickens on a continuing basis. The TCM may be further incorporated into water soluble polymeric compositions which permit the TCM to be leached out in a controlled manner. Further the TCM may be incorporated into cellular and noncellular polymeric compositions which may be used as bedding/litter material, and cat litter.
