Rainwater harvesting and storm water recycling are similar processes, but rainwater harvesting usually involves collecting water from cleaner surfaces, such as roofs, while storm water typically is ground-level runoff. Both require collecting, storing and conserving rain for later use.

The point-of-entry (POE) market for ultrafiltration (UF) membrane systems has grown considerably in recent years. Respected market researchers Frost & Sullivan had predicted that the market for hollow fiber UF membranes would increase at a compounded annual growth rate of 12.9% from 2004 to 2010, though there are signs that the actual growth rate during the latter part of this period may be above original estimates.

The creeks flowing from the peaks of the Rocky Mountains provide a good source of drinking water for the residents of East Shoshone County, Idaho. For decades, drinking water for approximately 1,400 households came from that surface water, which was treated only by chlorination.

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.
Application Requires Softening, Reverse Osmosis and Other POU/POE Technologies to Purify Water on an Ongoing Basis
On November 26, 2001, the new arsenic standard was signed into law—lowering the acceptable level for the contaminant from 50 parts per billion (ppb) to 10 ppb. Approximately 4,100 municipal water systems serving nearly 13 million people nationwide are affected by the law and are required to meet compliance by January 2006. According to the U.S. Environmental Protection Agency (EPA), 97 percent of these systems are small systems serving fewer than 10,000 people each. The economic impact on these small systems is likely to be large. However, there currently are options available to small municipalities that may be more affordable than central treatment.
New POU Technologies May Be the Answer for Small Municipalities Facing High Costs
West of Scotland Water (WoSW) awarded a contract, under competitive tender, for its first ultrafiltration plant to PCI-Water. This is the first installation in the United Kingdom using a hydranautics-based UltraBar system.
