The RO system has proven to be very reliable, and has been offline less than 1% of the time for maintenance, filter changes and membrane cleanings.
Wax manufacturer selects 150 gpm RO system to pretreat incoming city water, which feeds plant’s steam boiler system
The geographically remote region around Puerto Bolívar is very arid, with desert-like conditions and little or no water available for the port’s operations.
Crane Environmental installed a reverse osmosis unit to supply clean feedwater to boiler units for electricity at a resource recovery plant.
Reverse Osmosis Eliminates TDS in Boiler Feedwater
Although the pump is a relatively small part of the overall cost of an RO system, expenses resulting from downtime and inefficiency quickly can diminish the productivity of the system and your return on investment. Due to the corrosive atmosphere and high demands on these sea water RO systems, special attention is required in the pump selection process. There are several key factors that will help to ensure optimum pump and system performance.
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
Most reverse osmosis systems waste as much as 20 gallons just to produce one gallon of product water. The new technology called "ZeroWaste" eliminates this problem by returning the concentrate water from the reverse osmosis system back to the home's plumbing, resulting in 100 percent efficiency.
No one wants to drink radium, nitrates or arsenic. However, if not for some technologically advanced methods of removing these contaminants, we all might be sipping on some very unhealthy water.
As the residential point-of-use (POU) reverse osmosis (RO) industry approaches its 35th anniversary, it is time for a reality check on the industry's progress to date as well as a look ahead to new technologies or improvements that the industry may introduce for POU RO systems in 2003.
Looking for Answers in 2003 and Beyond
While high concentrations of arsenic are found mostly in the Western region of the United States, parts of the Midwest and New England show levels of arsenic
that exceed the newly approved U.S. Environmental Protection Agency (EPA) standard of 10 parts per billion (ppb). Individuals not willing to wait for their water system's compliance with the arsenic standard currently are looking for treatment systems to use in their homes. POU and even point-of-entry (POE) treatment systems are an attractive solution for these individuals. The process should begin with a basic understanding of arsenic contamination and the element's chemistry, a complete water quality analysis of the application-specific water and the knowledge of available technologies.
