Abstract: A method of controlling the concentration of P of cleaning solution waste water starts by providing a waste water buffer tank capable of either sending the waste water to a waste water treatment plant or storing the waste water after the waste water is accepted. The concentration of P in the cleaning solution is set within a target concentration range, and matter to be treated is treated. The concentration of P in the waste water is measured in the waste water buffer tank. When the measured value of the concentration of P is less than a selected upper limit, the waste water is sent from the waste water buffer tank to the waste water treatment plant. When the measured value of the concentration of P is higher than the selected upper limit, sending the waste water to the waste water treatment plant is stopped, and the waste water is stored in the waste water buffer tank. The concentration of P is reduced to a value within the target concentration range, and the matter to be treated is treated.

Abstract: A method and apparatus for treating water such as ballast water in ships in order to eliminate aquatic organisms in the water.

Other means may be used to generate further mechanical, electrical, and chemical forces in the water which attack the organisms.

Abstract: A method and composition for reducing chemical oxygen demand is presented. The composition includes a persulfate donor and a transition metal catalyst in contact with the persulfate donor. When the composition is contacted by water, the transition metal catalyst reacts with persulfate and reduces the persulfate concentration in the water.

As the persulfate concentration is reduced rapidly in the water by the catalyzed reaction, the persulfate-containing cleaning product may even be used while the aquatic facilities are being used. Optionally, a free halogen donor may be incorporated into the composition. The composition may be in the form of powder, granules (coated or uncoated), or agglomerate.

Abstract: Micro- and nanofilters have a wide range of applications in many fields, including medical diagnostics, drug delivery, medical implants, and hemodialysis. Some issues that limit commercial application of current nanofilters in medicine are low pore density, non-uniform pore size, and the use of materials that are not biocompatible. A method is described to fabricate high porosity polymer and diamond micro- and nanofilters producing smooth, uniform and straight pores of high aspect ratio.

This technology allows etching polymeric materials in a clean, well-controlled, and charge-free environment, making it very suitable for fabricating nanofilters and other components for biomedical applications.
