Water treatment sytems for a house

WATER ANALYSIS

To select a water treatment system, first of all, it is necessary to analyze the water. It is important to note that water cannot be taken for analysis immediately after drilling. Since immediately after the installation work, the ground does not adhere tightly to the pipe and different layers of groundwater can be mixed. The best time to take water for analysis is 2 months after drilling the well. In this case the result will be more accurate.

Well water analysis is carried out according to several indicators. The main requirements that water must meet, according to all-Union State standards:

• muddiness ≤ 1 mg/dm3
• coloration ≤ 20 degrees
• odor ≤ 2 points
• total hardness ≤ 7 mmol/dm3
• total iron ≤ 0.2 mg/dm3
• total salt content ≤ 1000 mg/dm3
• nitrates content ≤ 50 mg/dm3

Untreated water from wells most often has deviations from the above norms. The use of such water for domestic purposes is harmful to plumbing, has a detrimental effect on the skin and hair, and the use of such water for drinking puts human life and health at risk. In order to cleanse the water from contamination and bring it to the norm, you need a comprehensive filtration of water for your home.

DESIGN OF WATER TREATMENT SYSTEMS

Having received the results of the analysis, experts understand what kind of water purification system for the house should be installed to solve existing problems. However, for a competent calculation of a water purification system for a home, other factors must also be taken into account.

First of all, this is the number of “wet zones” in a house - that is, the points to which water is supplied, as well as the number of people who will use it. The load on a water filtration system for a home is calculated based on the scenarios of its use. For example, in the morning and in the evening on weekdays, large families often use water in all "wet zones" at the same time. Accordingly, the load on the water treatment system will be maximum. And on weekends - most likely the water will be used chaotically throughout the day without maximum load at one point of time.

Another very important factor that many people forget about is the throughput of the selected plumbing. Alter Air always studies the technical data sheet of plumbing before designing a water purification system in private houses and apartments, since the efficiency of the purification system depends on it. For example, tropical showers with a high water flow rate (up to 40 liters per minute) are now especially popular. The water purification system must be designed for such volume, otherwise the water treatment will be of poor quality.

Thus, when calculating a water treatment system, you always need to take into account: the number of wet areas and people living, as well as the technical characteristics of plumbing.

Technical cleaning

Technical water treatment is needed for domestic water preparation - for boilers, washing machines, dishwashers etc.

Technical water purification in a private house includes several stages:

1. A coarse filter is installed at the entrance to the house, which cleans the water from sand and other large impurities.
2. Iron remover - removes iron and other heavy minerals from water. After deferrization, the water becomes softer, which ensures a long-lasting operation of plumbing without plaque. Another nice bonus is the blue tint of the water.
3. Softener - responsible for high-quality water softening. It becomes more pleasant to use and healthier for human skin and hair. Clothes become more durable when washed, while maintaining the color and softness of the fabric.
4. Ultraviolet disinfection - effectively removes all bacteria and trace elements in the water. Alter Air does not recommend installing an ultraviolet water treatment lamp in a house without special medical indications. Such water treatment makes the water sterile, depriving the body of the ability to form immunity even for non-essential microbes. This can have a detrimental effect on health when using non-sterile water, for example, on vacation at a hotel, where the water is not disinfected with ultraviolet light.
5. Reverse osmosis for drinking water purification

After the process of technical cleaning, cold water enters a water heater. Such system keeps the plumbing, faucet and boiler in perfect condition, without deposits and other possible contamination. It is difficult and expensive to purify heated water that is why it is done before.

Reverse osmosis

After technical water treatment, you can proceed to the purification of drinking water using reverse osmosis.

The main element of reverse osmosis is a membrane that allows only a water molecule to pass through. Since after passing through the membrane, the water becomes as purified as possible, it must be saturated with useful minerals. For this, a special cartridge is used - a mineralizer, which corrects the mineral composition of the water. Thus, we get high-quality, healthy and tasty water.

Bottled water, which is sold on the shelves in stores, goes through the same stages of water purification. According to ISO standards, it first undergoes technical purification and then is filtered using reverse osmosis, only on an industrial scale.
