Whole house filtration systems are the end of the line in defense against contaminated water. They are becoming more popular as a non-visible way (compared with end of faucet filters) to ensure safety at point of entry in the house.
POE Filter Addresses Contaminant Concerns
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
Finding the right housing depends a lot on the application in which the housing will be used. Being familiar with your water filtration needs as well as researching the benefits of various types of housing will help you make the right decision.
The following is part two of a two-part article.
Problem: Giardia in the lake water (Buckskin Lake, Ontario) from beavers. An additional problem of bio-film clogging filters once system was installed. Solution: Hallett 13 Ultraviolet System with Crossfire Technology and filters. Results: Purified water from lake, improved taste and eliminated bio-film
Cottage Retreat Provides Pure, Safe Water for Everyone
The cartridge often is thought of as the heart of a filter system. However, the cartridge operates within a housing and even a cartridge that is perfectly matched to the application won’t perform adequately if it’s not also matched to a housing that meets the same application requirements. Specifying them together as an integrated system is the best way to assure they provide optimal performance.
Various authors have studied the use of activated carbon and for the most part have concluded activated carbon is not a cost-effective solution. However, these authors have failed to realize the limitations of carbon validation methods or the fact that not all carbons are alike, especially when chemical reactions control the process.
Presence of the bacteria Legionella pneumophilia in hospitals and nursing homes in the U.S. and Europe has been detected at an alarming rate. Contaminated water has frequently been found to be the source. Legionella is found naturally in water but multiplies in heating systems.
Legionella bacteria and other pathogens blocked for high-purity water
Whether it is an issue of limited space, material compatibility or just challenging feed water, there always will be a need for custom-engineered solutions in the water treatment industry. Lee Co. of Nashville, Tenn., first looked at preengineered reverse osmosis (RO) systems from its local water treatment equipment dealers. The company quickly realized that this approach would not fit a particular situation.
Custom-designed nanofiltration system solves space and process challenges
Although the basic components of any filtering system include the filter console, the communications link, the actuators and the instrumentation, it is the turnkey integration of these components into a pre-packaged, pre-engineered and even pre-programmed system that merits its classification as a major step forward.
Simple, low-power network architecture with menu-driven central control can revolutionize filtering operations
The Watsonville Wastewater Treatment Facility currently pumps 400 gallons per minute through the Tekleen water filter manufactured by Automatic Filters in Los Angeles.
