Water Treatment Patent

System for controlling water treatment based on plankton monitoring

In a water supply plant which cleans water taken in from such sources of intake water as lakes and marshes, dams, rivers and so on and delivers the water as city water, obstructions to water treatment is predicted and methods for preventing the obstruction are decided, by measuring kinds and quantity of plankton and comparing the measured data with rules representing relations among kinds and quality of plankton, obstructions to water treatment and counteractions to such obstructions stored in a rule base in advance.

Compositions and methods for water treatment

Materials and methods relating to water treatment processes are described. More specifically, the process is non-toxic and is useful for the removal of algae, other suspended solids, or contaminants in surface waters or in potable water treatment . Coccolithic calcium carbonate can be used in combination with a flocculent such as aluminum chloride to obtain the desired results.

Water treatment system

The present invention comprises an improved method and apparatus for treating water in heat exchange systems. The present invention automatically and inexpensively provides an effective chemical to process water systems at times and in proportion to the need for water treatment in such systems. When used in evaporative cooling systems, the present invention adds the treatment chemical to the system via the make-up water. The make-up water acquires a substantially constant concentration of treatment chemical as it is passed through a device containing a treatment chemical. The constant concentration of chemical is achieved by dividing the make-up flow into two streams within the device, saturating the smaller of the two streams with chemical, and re-mixing the two streams. The biocide agent used in the preferred embodiment of the invention is prilled elemental iodine.
