PUROTwist makes high quality water filtration systems
using Omnipure's exclusive Twist Tap filters. This type of water
filtration system is used to improve drinking water taste and
depending on the type of filter selected can remove chlorine and
lead.
Q. What is Water Filtration?
A. A process in which water passes
through a water system that may include one or more filters for
the purpose of removing turbidity, taste, color, iron or odor
and certain chemicals such as chlorine. The design can be loose
media tank-type systems or cartridge devices. In general the process
may include mechanical, adsorptive, neutralizing and catalyst/oxidizing
filters.
Q. What is activeated carbon and what does
it do?
A. Carbon used in filtration applications
is produced by grinding a carbon source - like bituminous coal,
peat or coconut shells and heating the material in the absence
of oxygen to 1000 degrees to bake off impurities. The material
is then subjected to 1600-degree steam to “activate”
the carbon. The steam leaves carbon granules filled with cracks
and pores, enabling them to store large amounts of chemicals.
One pound of activated carbon (the amount in a standard ten-inch
filter cartridge) has the equivalent surface area of a 160 acre
farm. Carbon removes contaminants in two ways: through adsorption
, contaminants are attracted to the surface of the activated carbon
and held to it in much the same way a magnet attracts and holds
iron filings; and by acting as a catalyst to change the chemical
composition of some contaminants. Activated carbon is ideal for
removing chlorine, organic chemicals such as many kinds of pesticides,
THMs like chloroform and many VOCs that are components of gasoline,
solvents and industrial cleaners.
Q. There is chlorine in my water. Is chlorine
bad for me?
A. Chlorine in itself does not
appear to be a problem other than the aesthetic concerns of undesirable
taste and odor it creates. There has been a lot of research on
the effects of chlorine with evidence showing that the biggest
concern being its reaction with natural organic materials like
leaves and humus forming disinfection by-products, which are considered
carcinogens. Installing a point of use water treatment system
that incorporates the use of carbon filtration can be very effective
in correcting this problem.
