How to choose the right water filter for your water source conditions

                Choosing a water purifier for home use is a matter of careful consideration. Each water filter system has different working principles and efficiency. Here are some things to consider when choosing a water purifier:

    Condition of the water source to be filtered

First of all, we need to know what type of water we use in our house, tap water or water from natural sources. In the case of tap water, it can be used with almost all types of water purifiers. But if it is water from a natural water source such as groundwater, it contains more minerals or minerals than tap water. You should choose a drinking water filter that has the ability to remove mineral salts. various salt solutions water hardness and a filter that can kill various microorganisms, etc.

    The quality of the water filter to be filtered

Should choose a water purifier that has been certified by ISO 9001, which is a certification standard in the production process. Or certification from other institutions such as NSF (National Sanitation Foundation International) drinking water quality standards from the United States, WQA (Water Quality Association) is an independent organization that certifies consumer products according to international standards, and T Mark (Thailand Trust Mark) is a Standard certification from Thailand, etc.

    Water consumption and size of the water purifier

Choosing a water purifier must be related to the amount of water used and the number of family members. There are many sizes of water filters to choose from. both in terms of filtration systems number of filtering steps Users should choose according to the condition of the water to be filtered. If you want to use a large amount of water in a large family Should choose a large water filter. Filter rods or filters in the amount appropriate to the amount of water used to filter. But if you want to filter the water in a small amount or used for filtering drinking water only Should choose a small or medium filter. to help reduce maintenance costs It can reduce unnecessary energy consumption and water wastage.

Can you drink groundwater? And what kind of filter should be used to filter groundwater?

                Groundwater is water that is stored or accumulated underground. along the crevices of the rock layers the gap between the pebbles or grains of sand beneath the surface There is usually very little change in the environment. Therefore, the quality is more consistent than surface water. Groundwater in some areas is of good quality. can be used for consumption But some sources have specific properties according to the source of that groundwater. Contains mineral impurities Sometimes it becomes brackish water. or have high hardness Contains iron or manganese. Consumables need to be removed with a filter such as a system with an Ion Exchange Resin filter, a Manganese Sand filter or a reverse osmosis (RO) filter.

Why are RO water purifier systems more expensive than other systems?

                The production of drinking water in the RO system is based on the principle of allowing raw water to penetrate through a very small porous membrane. only allow water molecules to pass through By its nature, this diaphragm is filtered between clean water and contaminated water. Clean water will seep through to the contaminated water side. The pressure that causes permeation is called osmotic pressure. This natural phenomenon is called osmosis, which is lost in clean water to contaminated water. Therefore, the production of RO water may be necessary to separate clean water from the water that has as much contaminants as possible, using the principle of defeating nature by osmotic pressure. The pressure in the contaminated water must be increased to a higher than the naturally occurring osmotic pressure in order to allow the clean water to separate and penetrate. This opposite process is known as reverse osmosis. For this reason, the essential equipment of RO drinking water production are membranes and pumps. including system control devices That is assembled into the RO water purifier system, making this system more expensive than general water purifiers. which is a system with more advanced technology than other systems as well

Why does drinking water taste different in each region?

                If talking about the production of water for consumption Water used to produce tap water comes from two major sources in nature, namely surface water and groundwater or groundwater. Surface water will change depending on the environment, such as seasons, may have high turbidity. and high organic The amount of mineral salts in the water may be more or less depending on the area of ​​the water source. The production of tap water from surface water is therefore more costly than ground water. and groundwater or groundwater It is a water that has very little natural change. which has a more consistent quality, is clear, contains the amount of minerals and solutions Contamination in water varies from area to area. Most of them have electrical conductivity. (Conductivity) than tap water produced from surface water. Some sources are brackish to salty. Therefore, the taste of water depends on the impurities or solutions known as mineral salts, minerals mixed in the water source. to be filtered for drinking
