Important Tips While Choosing Different Types of Water Purifiers

Why is it emphasized on the necessity to use a water purifier at home and work today?

Because of the growing population and the increasing industrial and human pollution in water and soil, the quality and health of the water have dropped even in cities that used to be healthy in the past. Infiltration and increasing the contamination in the water, especially nitrate of human wastewater to the layers of groundwater and water resources are very dangerous and can increase the risk of various diseases.

What is the most dangerous cancer factor in water?

One of the most dangerous substances in water is nitrate, which is one of the main carcinogenic factors, especially for stomach cancer. Therefore, a method called reverse osmosis is used to remove nitrate in water. In fact, the reverse osmosis system consists of membranes that have holes with very small nanoscale dimensions that only water molecules can pass through, and particles that are larger than water molecules cannot be passed. Home water purifier devices with reverse osmosis technology, eliminating impurities and water hardness, provide a healthy, lightweight, and soft water.

Important points about the necessity of using a home water purifier include:

  • In urban water treatment plants, nitrate, which is one of the most dangerous pollutants in the water, is not eliminated in any way, and it is needed to remove it with a water purifier equipped with advanced filtering.

  • In urban refineries, chlorine added to eliminate bacteria and disinfect water is directly linked to many cancers, fetal abnormalities, heart disease and asthma, as well as the carcass of microorganisms killed by chlorination remains in water which is the source of another pollution in the water.

  • Usually, refined water from urban wastewater treatment plants runs through rusty and old kilometers of pipes, which contaminates refined water.

  • As chlorine gas is harmful to the human lungs in the pool or bath and also the contact of chlorine with skin and hair causes hair loss and damage to the skin, it is recommended that the chlorine in the urban water supply system is completely removed by home water purification devices.

  • In order to maintain long-term water quality in mineral water bottles, preservatives such as fluoride in water are used in these bottles, which is a chemical agent and its continued use is also hazardous.

  • Be sure to note that boiling water does not eliminate the microbial contamination in the water and does not eliminate the impurities and hardness solved in the water, but more boiling water increases the amount of salts and nitrates present in it. This matter itself causes many diseases, so despite the fact that there is a very wrong belief among people, boiling water does not improve the quality and purification of water. According to the above conditions, we can say that today one of the essential requirements of life is the use of a device to ensure the provision of high-quality water to us and our beloved ones, so there's no choice but to use a valid water purifier.

Comparison of mineral water and water purifier:

Salts

Salts and compounds in mineral water are deposited in the body after successive use and cause diseases such as kidney stones and etc.

Expiration date

Mineral water in Europe is only valid for one week, but mineral water in Iranian stores up to 6 months???

Preservatives

Mineral water companies half a milligram of fluoride to one liter of mineral water, which is a flavorless and odorless preservative, and is carcinogenic and extremely dangerous to the human body. When fluoride enters the body's tissues, it occupies the tissue's environment and causes Inter-tissue water to escape; The body automatically creates a slippery layer that grows over time, which is called water retention. The outlet water of the water purifier is free of preservatives and is perfectly suitable for the body.

Storage condition

Mineral water is supplied in plastic packaging that has special storage conditions. For example, mineral water packages should not be exposed to direct sunlight, while the conditions for maintaining mineral water in Iranian stores are not standardized.

Plastic packs of mineral water release the polymeric material in the sun that dissolves in water, and polymer materials are very dangerous to the health and carcinogenic.

The water purifier does not add any polymeric materials to the water.

Economic efficiency

Using home water purifier at homes and apartments provides you with a healthy and light water, which is economically and qualitatively viable compared to mineral water bottles.

If a family buys a water purifier, the cost of this device is less than the bottles which are bought during some months and will be compensated.

In fact, spending to buy a water purifier is a very intelligent work.

Helping nature

Daily use of mineral water bottles is extremely damaging the nature. We humans should not over-use plastic materials to help have a more beautiful and cleaner planet.

Affordable water purifier device

Recently, water purifiers have been imported into the market that are not well-suited and do not meet the standards required to completely eliminate pollution and harmful substances in the water, but due to the good prices, they may attract some customers.

But, the fact is that the water purifier is related to human health and you have invested for yourself and your family by the cost you pay for it.

To achieve a clean, clear and refined water, the water purifier should have at least 5 main membrane filters, fiber filters, active carbon filters, salts filters, etc.

Selection and operation of water purifier:

  • One of the points that is usually considered by the buyers of home water purifiers is the volume or capacity of the water reservoir of the water purifier. It should be noted that, firstly, the volume of the reservoir of the device has no relation to the ability of the device, and secondly the volume of the tank of the home water purifier should be just fit the amount of family consumption. (For example, the volume of water needed for a small family, which consumes about 3 to 5 liters daily, will be up to 6 liters to use the reservoir water at least once a day, and be replaced by fresh water as soon as possible.) It is also evident that using larger tanks is appropriate for more uses.

  • Home water purifier requires regular and persistent maintenance to keep its function. Among other things, it is important to maintain the proper functioning of a variety of home water purifiers are changing cartridge filters, reverse osmosis membranes and other possible cases in the manual of the water purification devices.

  • In order to select a suitable water purifier, checking items such as the size and dimensions of the device, the location of the installation the home water purifier (under the kitchen sink, on the wall, kitchen counter, etc.), the duration of the replacement or washing of the filter, the installation and replacement cost of the filter, warranty terms and after-sales service of the water purifier and etc. are recommended.

  • The replacement times of filters for water purification devices differ because of the type of water hardness in different regions of the country, which the necessary explanations regarding the time and how to change the filter is provided by the installer to the customer at the time of installation.

  • Buying a high-quality water purifier guarantees your health, and the cost you pay for it is actually your investment for the health of your family. Today, due to the presence of various microbial and chemical contaminants in water, using the water purifier is not a choice, but one of the requirements for family health. By purchasing cheap and inexpensive water purifier devices, do not throw away money and, with the right choice, install the appropriate water purifier at home and be comfortable with the cost you paid, as well as the after-sales service.

Number and types of standard water purifier filters:

The number of filters installed in the home water purifier devices alone does not represent the high quality of water output from the water purifier. In addition to the number and purification process, the type of filter and the technology used in them is also important in improving the quality of output water from the device. (Be careful about the originality of the home water purifier filter, which affects both the quality and the price of the device, and the quality of the water used is not worth the low cost of some home water purifying devices that are practically inefficient).

Filters used in the water purifier include:

water purifier

  • Polypropylene filter: To remove all deposits, sand, mud, corrosion of pipes, sludge and suspended particles up to 5 microns in diameter, which have the same function as a sand filter and absorbs visible contamination in the water.

  • Powder Carbon Filter: To remove chlorine, agricultural toxins, trihalomethanes and most of the organic chemicals found in insecticides and pesticides, and remove the color and taste and smell of water.

  • Carbon black filter: to remove the highest levels of chlorine and toxic substances.

  • Membrane: Removes 98% of harmful salts, including microbial contaminants, nitrates and nitrite and heavy metals.

  • Linear carbon filter improves the taste and smell of water when stored for long periods of time in the reservoir.

  • Bio-ceramic filter: To adjust PH and improve the taste and flavor of water.

  • UV lamp: Ray diffraction method (UV) using UV lamp to disinfect, sterilize the water and all the microorganisms.

  • Alkaline filter: To raise the PH of water.

  • Mineral Filter: adding minerals required by the body after complete water purification for water softening.

General explanations about the mechanism of operation of the water purifier and the changes that it creates:

Purification phases in a 6-phases domestic water purifierare as follows:

Water Purifier

The water purification steps by the 6-step home water purifier are as follows:

  • Step one: At this step, mud, sand, and other detritus in water are removed from the water by a 5-micron fiber filter.

  • Step two: At this step, the active carbon filter embedded in the water purifier device is responsible for the removal of gases and chemicals in pesticides and insecticides.

  • Step three: The active 1-micron carbon filter purifies the water by removing chlorine and materials larger than one micron if it passes through the two previous filters.

  • Step four: Membrane filter (RO), which is essentially the main filter of the water purifier, is composed of several layers of the semipermeable membrane formed by a central tube. It refines all soluble salts (nitrate, lead, calcium, etc.) between 80 Up to 98%. The filter has the ability to remove harmful minerals to a size of one-thousandth of a micron (organic and inorganic substances dissolved in water and microbial contaminants) as well as the ability to eliminate water hardness.

  • Step five: At this step, the odor and taste of the water that may be taken after a while in the reservoir are destroyed.

  • Step Six: The UV filter embedded in this step, is responsible for the microbial decontamination of the water by infusing the ultraviolet rays into the water.

What is reverse osmosis?

In fact, the main filter is the reverse osmosis filter in a water purifier. The reverse osmosis filter consists of several layers of semi-permeable membranes that are wrapped around a central tube. This membrane has a pore size of one-tenth of a nanometer (0.0001 microns). Because water-soluble impurities are not able to penetrate the pores of this membrane, there will be pure water on one side of the membrane. It enters the central tube and leads to the outlet of the treated water. On the other side of the membrane layers, there will be impure water directed to the sewage duct. By reverse osmosis, microbial and chemical contamination is reduced by 90 to 98 percent. Nitrate, arsenic, lead, mercury and other water-soluble impurities, and harmful heavy metals in water are removed at this step.

water purifier

The factors affecting the performance of the reverse osmosis system are:

  • Inlet water pressure
  • Water temperature
  • Type and amount of total dissolved solids (TDS) in tap water
  • The quality of the filters and membranes used in the RO system
  • It should also be noted that the reverse osmosis membrane filter can remove impurities and particles larger than 0.001 microns.

What is TDS?

All of the impurities in the water (TDS) are called Total Dissolved Solids, which its measurement unit is ppm. More ppm of water morewater salt or more contamination, and the smaller it is, the cleaner the water. (For example, Tehran's water PPM is usually about 250.)
