Drinking Chlorinated Water Is Also Harmful To The Health Of Human Beings

Extraction of the chemical was convenient at first because of bad taste and odor. Activated carbon and carbon water purifiers started appearing in homes. Today is one step of carbon in almost all water purifier on the market. The move has even been added to the expensive RO systems.

Now, we know. Not only the chemical taste bad, but the chlorinated drinking water is also harmful to the health of humans. The fact that bacteria are killed should be an indication, but sometimes scientists do not think ahead. To solve a problem and create another, unknown, or two.

In order to solve new problems, new water purification systems have been developed for domestic use. Many people still cry for the government to do something, but it seems that in this situation, we must take care of ourselves. There is no realistic way you can stop using chlorine as part of the public in the purification process. They can use UV lights in the installation, but once the waters leave the premises and stored for use by humans, bacteria, protozoa, parasites, algae biological material and others could begin to grow. That’s why again is added as a final step.

The only option we have is to use one in the kitchen. Water purifiers remove chlorine are good, but they eliminate THMs (chlorination byproducts) are even better.

The adverse effects of chlorinated water consumption include digestive problems, respiratory illnesses and allergic reactions. In the long term adverse health effects including cancer. Both chlorine and THMs themselves have been linked to rectal and breast cancer. Obviously, it is necessary to purify water, but does not have to drink.

Industrial Media Filters

Stainless Steel Tanks
Pure Aqua pressure filters clarify water by removing sediment, turbidity, iron, unpleasant tastes and odors, suspended particles, and unwanted color, all of which are commonly found in surface water. They can be used in a variety of service conditions including, but not limited to: industrial, municipal, and institutional applications.

STANDARD FEATURES

* Quality Tank Construction: All tanks are constructed of high quality welded 304 stainless steel and designed for a 100psi operating pressure, where higher pressure is available as an option. Standard tanks are equipped with inlet and outlet connections, and top mounted loading port; tanks are also sandblasted form the inside and out.

* Underdrain: Hub and lateral distribution system is designed to utilize the entire bed area during operation. This minimizes channeling during periods of low flow. The underdrain is constructed of schedule 80 PVC laterals.

* Automatic Diaphragm Valves: To have a trouble free system, we design the ultimate water filter using a “Nest” of corrosion resistant diaphragm valves. The angular design, high lift, and large seat opening of the hydraulically operated valves provide a minimum restriction to flow. In a manual filter, a butterfly valve is used for backwash.

* Timer/Controller: The standard method of control for automatic units is a stager with and integral clock timer. The control has a built in manual override in case an off schedule backwash is needed.

MULTI-MEDIA WATER FILTERS (Depth Filters)

Multi-media water filter system represents a significant improvement over single-media filters. This is primarily due primarily to improved filter bed action based on the innovative use and selection of filter media. Multi-media filtration permits delivery of high quality filtered water at much faster flow rates, as compared to a conventional sand filter.

In a conventional sand filter, lighter and finer sand particles are found at the top of the filter bed, and coarser, heavier sand particles remain at the bottom after backwashing. Filtration takes place in the top few inches of the filter bed.

A multi-media filter is backwashed in the same manner as a sand filter, using reverse or upward flow of water through the filter bed. The various layers of media retain their stratification because each material has a different density.
Advantages

1. The multi-media water filter systems operate for much longer periods of time (five or more times as long at the same filtration rate), before backwashing is necessary because the bed can hold more turbidity. Turbidity is trapped and held throughout the entire bed depth, rather than the top one or two inches.

2. Multi-media filtration is much better suited for use in a closed pressure tank since cracking of the bed, and subsequent breakthrough of turbidity is virtually eliminated and the need for visual inspection is unnecessary.

The use of pressure tanks, rather than open basins or filters, is an obvious advantage for point-of-use filtration and could also be of real importance in the filtration of small community water supplies.

More rapid filtration flow rates in multi-media filtration allow the use of smaller diameter tanks with equal or better results.

3. A very high degree of clarity is achieved in the filtered water because of the fact that the finer particles of garnet at the bottom trap finer turbidity particles.

4. Another important advantage is that multi-media water filters can clarify water at a much higher flow rate than a single-media sand filter (5.5 to 8 gallons per minute, as compared to 1.5 to 2.5 gallons per minute in a 12 inch diameter tank). This is 14 to 15 gpm per square foot of bed area, as compared to 2 gpm per square foot of bed area. This is a very important difference in the production of filtered water.

Pure Aqua’s multi media water filters (MF-1100, MF-1000, MF-600, MF-500 MF-450, MF-410 MF-400 Series) clarify water by removing sediment, turbidity, iron, unpleasant tastes and odors, suspended particles, and unwanted color, all of which are commonly found in surface water. They can be used in a variety of service conditions including, but not limited to: industrial, municipal, and institutional applications.

Pure Aqua multi media water filter systems are ideally suited for use where stringent water quality standards are required or where higher levels of suspended solids are present. These applications can include re-use applications, water pre-treatment applications for reverse osmosis and deionization systems or as a pre-treatment system prior to disposable bag or cartridge filters. Pure Aqua multi-media water filter systems are also widely used as primary water filters for removal of suspended solids in incoming plant water or in waste water clean up applications.

Why a pressure filter?

Pure Aqua pressure filters clarify water by removing sediment, turbidity, iron, unpleasant
tastes and odors, suspended particles, and unwanted color, all of which are commonly found in surface water. They can
be used in a variety of service conditions including, but not limited to: industrial, municipal, and institutional applications.

Filter Media

Anthracite: Performs nearly identical to a sand bed, but is used in applications where silica pick-up from the sand is
objectionable.

Sand: The most common filter media, used in most filtration systems. Generally fine mesh sand is coupled with a course
grain support bed to remove suspended solids and turbidity.

Gravel: Gravel has a highly spherical shape that promotes good flow and even distribution in support beds.

Filter AG: A non-hydrous silicon dioxide media with outstanding advantages for reduction of suspended matter.

Activated Carbon: This media is recommended for the removal of unpleasant tastes, odors, dechlorination, and organic contaminant adsorption.

Manganese Green Sand: This media is capable of reducing iron, manganese and hydrogen sulfide from water through oxidation and filtration.

Multi-Media: When top quality water is required and unwanted sediment is too small to be removed by standard media,this type of bed is the preferred choice. It consists of multiple layers of increasing grain size. Multi-Media filters will remove sediment down to the 10-micron range.

Water Purification Methods

Choosing the correct water filtration system for your home depends much on your needs. Your health should be first in the order of importance.

All of us want the healthiest drinking water possible and with today’s water purification technology, we can all have that, without spending a fortune. Every company will tell you that the methods of water purification system that they use are the best, but you can not always take their word for it.

Here’s what you should know about the different systems you will find on the market today.

Distillation

This is one of the oldest methods of water purification. In brief, water is passed over a heated coil, causing it to vaporize. The steam rises and is transferred to a cooling chamber, where it once again becomes liquid. Inorganic compounds, such as lead, calcium, magnesium and other minerals are left behind. Bacteria are destroyed.

Chemical contaminants such as chlorine, pesticides and herbicides are vaporized along with the water, because their boiling point is lower and so enter the cooling chamber along with the water.  Water purification technology has advanced beyond the distillation method, as the need to remove chemical contaminants has increased over the years.

Reverse Osmosis

Reverse osmosis system is another of the older methods of water purification. It has been around for over fifty years. It works by forcing pressurized water through a semi-permeable porous membrane. Inorganic compounds are removed by this system, as they are with distillation, but once again, synthetic chemicals will pass through along with the water.

Water purification technology has advanced beyond this method, as well, and has also become more affordable. RO systems for the whole house cost in excess of several thousand dollars, not to mention the cost of wasted water and the electricity needed to pressurize the water. Some models may be much cheaper and not use electricity. This is not the best choice for the home

Pitcher Filters

The idea of portable inexpensive methods of water purification has made pitcher and carafe-style filters increasingly popular in recent years. Although it took more advanced water purification technology to develop pitcher filters, they are not the most effective. Pour through filters are a slight improvement over tap water, because they do block a lot of the chlorine, but they cannot block other chemical contaminants, nor can they remove bacterial cysts. They can filter out lead, which is a good thing. They do cost less initially, but because the filters must be replaced so often, they cost more to use than a countertop or under the counter filter.

Multi-media Block and Activated Carbon Filters

Activated carbon is recognized by the EPA as the best water purification technology available today for the removal of chlorine and its by-products, pesticides and other synthetic chemicals. The chemicals are bound to the surface of the filter medium and cannot pass through with the water. Multi-media block filters remove sediments and bacterial cysts, while balancing the mineral content and pH levels of your tap water.
