Ultrafiltration Membranes

With an aging and often overwhelmed water supply infrastructure, evermore stringent government regulations and growing industrial requirements for pure water, municipalities and companies are increasingly turning to ultrafiltration (UF) membrane systems for water and wastewater treatment.

Using Membrane Systems for POE Disinfection & Clarification

Until recently, using membranes for whole-house residential clarification and disinfection had not been an option for water treatment dealers. Technical advances made by Zenon Environmental in hollow fiber membrane technology for its large-scale municipal and industrial plants have changed this. Membranes are now being used in the company’s Homespring point-of-entry (POE) systems, providing a cost- effective solution for the removal of turbidity and pathogens, and delivering clear, biologically safe water.

Cooling Tower Water Treatment

Microorganisms tend to thrive in the re-circulated water and on wet surfaces. Bacteria, slime and algae foul heat– exchanger surfaces and in some cases attack and destroy system components.

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.
