Metals Plant Needs High-Purity Water

Dayton Progress Corp.'s focus has been on manufacturing metal punches, punch blanks and metal stamping tools. It also would take experienced water treatment professionals to ensure that the proper quality water was used in each process. That is why it relied on Crown Solutions, Inc. to manage the point-of-use (POU) and point-of-entry (POE) water treatment for each of its manufacturing processes that required water.

Water Treatment: Thinking Small

As populations grow, as urban, suburban and ex-urban areas expand, demand for water increases and safety standards rise. An effective and creative way to deal with problems of growth and resource management might just be to think small. A case in point is the Olivenhain Municipal Water District's (OMWD) treatment facility in San Diego County, California.

Filtration Fundamentals

Over the years, water quality has noticeably deteriorated worldwide. This decline in water quality stems from the extreme demand on very limited natural resources. Various principles of filtration are used in many applications to improve the general quality of the water that is being treated. Along with screen filters, coagulation/filtration, neutralizing filters, oxidizing filters, clairifying filters and carbon filters are other treatment methods that may be used.

Ultraviolet Dechlorination Technology

At the Procter & Gamble manufacturing plant in Greensboro, N.C., an Aquionics ultraviolet (UV) dechlorination unit was installed before two banks of reverse osmosis (RO) membranes. Trials that ran soon after the UV system’s installation showed a dramatic reduction in the RO membrane wash frequency—down from an average of eight cleanings per month to only two per month.
