Water Filters

What are water filtering systems?

By water filtration system, we mean a mechanism that is specially designed to remove solid, small or large particles from the interior of a liquid by using a wide filter that allows only the passage of the liquid, but stops solid particles which are unnecessary. 

 

A normal filter removes impurities that the water does not need by using a small physical barrier 

that reduces the level of pollution. Filters are used at different levels and clean the water to be used at different levels, for example: agricultural water without pollution, industrial water used for cooling systems and drinking water for the public.

What is a water filter?

The water filter is a device that removes sediments and water pollutants in a way that makes the water look clearer, besides it makes the water taste and smell better. It makes the water healthier to drink and to use for other activities such as cooking and washing dishes. 

 

In most cases, water filters use different mixtures of carbon to remove pollutants and prevent them from settling where you live, for example in your home at your kitchen sink or anywhere else you don't want the water you use to be contaminated.

Why is water filtering needed?

As we know, water filtration makes bacteria and other harmful agents found in water go away and thus we have clean water for drinking and other necessary life activities.Water filtration removes contaminants such as chlorine and heavy metals such as mercury and arsenic. 

 

At the same time, water filtration prevents important minerals such as magnesium, calcium, and zinc from leaving the water. Water filtration also has health benefits, it makes you have a hydrated skin, absorbs the right nutrients, detoxifies the body and also removes the risk of cancer. 

 

Drinking clean water helps the human immune system and the proper functioning of mental health. Another side that we benefit from filtering water is that the water has a better taste and smell, which makes us enjoy it more when we drink it.

 

Hard water and issues with it 

 

White and solid deposits that hang in your faucet, as well as the inability of the soap to create foam properly, all these are signs that you are using hard water in your home.Hard water has large dissolved amounts of calcium and magnesium.

 

The ions that are most often present in hard water are the metal ions of magnesium and calcium. But also iron, manganese and aluminum can be present depending on the area where you are. 

 

All these metals are soluble in water, so these metals will dissolve in the water you use. Hard water is more present in places where limestone and gypsum are present. 

 

Hard water makes equipment and pipes not work properly, it also leaves deposits of various minerals in glasses and other containers.

Elements found in hard water that make it dangerous

 

Hard water usually has a high content of magnesium and calcium, which makes the water hard. But in addition to these elements which are not so dangerous for human health, hard water can sometimes contain elements that are dangerous for drinking and human health. 

 

One of these elements is arsenic, which can potentially cause problems for human health. Also, some other elements that can be called dangerous are: aluminum, barium, strontium, and zinc.

Different types of water filters and filtering methods

Reverse osmosis

Reverse Osmosis (RO) is a technical process that uses a pressure pump to force water molecules through a membrane that is semi-permeable.

 

This membrane is an advanced reverse osmosis water filter. It acts as a selective barrier, with the membrane allowing only certain particles to pass through. During water treatment, the result is that the ions remain on one side of the membrane, while only water molecules are allowed to pass through the membrane. The water is thus deionized when it is forced through an osmosis filter.

 

With reverse osmosis water purification, you get clean, top-quality water straight from the tap. Without having to worry about harmful contaminants, pharmaceutical residues, pesticides, chemicals, or bacteria polluting the water.

 

Activated carbon water filters

 

Carbon filtration is a very effective method of water purification, providing the removal of many chemicals that can be found in water. Activated carbon filter is a type of filter used especially to separate organic chemicals from water. 

 

These filters also purify water by removing chemicals that change the taste and smell of water, such as hydrogen sulfide or chlorine. Activated carbon filters are used in water purification devices

Mains water may contain volatile chemicals such as chlorine, benzene, pesticides or herbicides, and hundreds of other chemicals.

 

An activated carbon filter removes pollutants, bad odors and bad tastes from tap water. In this way, you get clean drinking water, which can also be advantageously used for other food-related purposes. 

 

An activated carbon filter easily absorbs chemicals in the water so you can enjoy a glass of water freed from impurities of all kinds.

 

Chlorine is used worldwide to ensure the use of water from the tap, but chlorine does not. 

Chlorine can also cause a bad taste or smell. An activated carbon filter is the most effective filter technology for removing chlorine by-products, e.g. trihalomethanes, from your drinking water.have an exclusively positive effect on water quality.

 

Ion exchange water filters 

Ion exchange is used to soften hard water. The water passes through an ion exchanger, which are granular organic substances that are insoluble in water. When hard water passes through a layer of ion exchanger, the Ca2+ and Mg2+ cations that are contained in the hard water are exchanged for sodium or hydrogen through ion exchange.

In water softening, softening filters are used, which also work on the principle of ion exchange. These filters are called catex filters. A filter that is filled with catex, which is a softening resin, is inserted into the distribution line and as the water passes through it, ion exchange takes place.

Ion exchange is a very important technological procedure both in domestic and industrial scale. Some industries are even dependent on ion exchange. Thanks to it, we are also able to remove some poisons and other harmful substances from water.

Uv sterilization water filter

 

The principle of UV water sterilization equipment is based on irradiating water with a very short wavelength (254 nm) spectrum of light. This spectrum is lethal to small micro-organisms, bacteria and viruses. Exposure to light for at least 2 seconds destroys the DNA structure of microorganisms, which disrupts the natural ability of cells to develop and reproduce. 

 

By irradiating water with UV light, pathogens (harmful bacteria) are neutralized and are no longer able to cause infection and disease in humans because they are unable to reproduce once they enter the body. Within a few days, these irradiated bacteria, viruses and microorganisms die.

 

The principle of UV lamps is simple: a special bulb is contained in a quartz glass casing, which is encased in a long stainless steel housing. 

 

As the water passes from one end of the housing to the other, it is irradiated with UV light. It is important to choose these devices correctly, as the best disinfection results can be obtained by passing the water very slowly through this housing. In fact, to obtain 99.99% sterilization efficiency it is necessary to limit the water flow to 1/4 of the maximum flow. For example, if a lamp with a maximum flow of 2700 liters/h is selected, the recommended flow is only 675 liters/h.

 

Solar-powered water filters

 

Filters that use the sun's energy to clean water are very effective because they remove bacteria, protozoa, and viruses through solar energy. This is made possible by mixing electricity produced by solar panels, collecting ultraviolet light or solar heating.

 

In most cases, solar energy filters use the sun's heat to heat the water to a point close to boiling for a short period of time and in this way the water is purified after the water is boiled as pasteurized water.

 

How to set up a water filtering system?

Filtered power water protects your household appliances from calcification. It also reduces the content of chlorine, lime, lead or copper. Installing a water filter is not a problem even for laymen. These instructions will work with most systems. If in doubt, consult the installation instructions for your filter.

 

  • First, mount the wall bracket to the filter housing with screws.
  • Turn off the water.
  • Loosen the hoses of the existing faucet in the kitchen using a wrench.
  • Mount the water hose (hot / red) to the angle valve for hot water.
  • Mount the filter inlet hose and the water hose (cold / blue) with the inlet line from the angle valve on the T-piece.
  • Insert the inlet hose with a shut-off valve into the quick coupling of the filter housing.
  • Mount the hose for the filter water on the fitting.
  • Plug the outlet hose with quick coupling onto the outlet of the filter.
  • Now connect the other end of the hose to the filter water hose of the fitting.
  • Mount the short inlet hose from the T-piece to the angle valve for cold water.
  • Then find a suitable place for the filter under the sink and screw it to the wall.
  • Slowly open the valve on the filter inlet and the angle valve and check everything for leaks.
  • Now you can also turn on the valve on the inlet hose.
  • Turn on your faucet and let the water run for about 5 minutes. In this way, you ensure that possible production residues of the activated carbon are completely rinsed out.

 

Cost of water filtering system

There are many different factors when choosing a filtration system. Each of the water filtration systems has a different effect that will affect the price. Prices vary by the size of the filter and the brand you choose, these are the main factors you should consider when choosing a filtration system for your home or elsewhere.

A home filtration system will cost between $50 and $9,000, depending on the type of filtration system you choose. For example, if you want to get a filtration system with carbon filters, it will cost you somewhere between 50 and 500 dollars, and the ultraviolet ray filtration system will cost you between 200 and 1000 dollars.

Water filters vs bottled water

There are various reasons to choose filtered water over bottled water. Because a quality filter that you have installed in your home or workplace can easily remove contaminants that are harmful to human health without having to go to the market to buy bottled water.

 

Using filters in your home can also save you money. Because for a family to consume the right amount of water during the day, it is cheaper than buying bottled water.

On the other hand, the bottled water industry is a very large plastic industry that can cause soil pollution, so these are some of the factors that make filtered water more suitable than bottled water.

 

Water filter FAQ

Do water filters improve the taste of water?

The filtered water tastes better - the filter reduces the amount of by-products such as chlorine and metals. Improved coffee experience when using water filter jugs, as the bitter substances in the coffee bind to lime. Using water filtration therefore reduces the bitter taste in coffee.

 

Do water filters provide any health benefits?

Drinking water containing chlorine, heavy metals or other impurities such as rust or sand is a health risk. Although there may be no adverse effects in the short term, in the long term health problems caused by drinking polluted water can be very serious. Using a water filter ensures that the water you drink is safe for your body. 

 

A water filter removes even parasites from the water, which are resistant to chlorine and can remain in the tap water. The water filter also removes heavy metals, chlorine from the water, as well as rust, sand or pesticides that can be found in tap water. You will therefore be able to drink water that ensures a healthy body. In other words, the water you drink every day will help strengthen your immune system.

 

Do water filters remove toxins?

The role of water filters is to remove toxins such as lead and plastic fibers. Some types are referred to as five-stage filters, which, according to the manufacturers, are capable of removing trace amounts of dissolved solids such as lead, mercury and fluoride. But because the amount and composition of these solids varies, it is not possible to ascertain how harmful or harmless they are. 

Are water filters easy to maintain?

In general, water filters are easy to maintain. They are easily accessible to clean when needed. You must set a regular time base to clean them so that they have a longer life. The life of a filter varies from the filter you are using, but usually most filters should be changed in a period of 6 to 12 months.
