Water cottage – one of the main tasks facing the owner at the time of commissioning of the object.
For some way – drilling of artesian wells, for the other – organization of the Central water supply. But in the first and second cases, a private water source may not be a guarantee of its high quality and suitability for human consumption.
Water purification from impurities, bacteria and viruses – the main problem of water supply of a private house. If for household needs (watering plants and trees on land) will fit almost any quality and chemical composition of the water, for drinking water coming from well water will have to be cleaned. The same applies to water used for water heating in a country house.
Raw water is visually may appear to be suitable for drinking and for household use. But carried out chemical and bacteriological analysis of the liquid extracted particularly close to big cities (and most of the cottage settlements located near cities) shows disastrous results: elevated concentrations of iron, high levels of turbidity and hardness, the presence of E. coli and other pollutants. This is not a complete list of what makes the water not suitable for drinking.
Many owners to save money neglected an additional cleaning, but in vain. Raw water leads to serious health problems (including cancer diseases), instantly disables any installed in the house plumbing, heating and water system.
It is for these and many other reasons it is important to use high quality, reliable water purification systems for country houses.
The effect of well depth on water quality
Well, broken even at great depths, is not a guarantee of high quality produced water. Consider the characteristics of water from wells of different depths.
Wells with small depths
Water with a specific smell and taste with high levels of bacteriological and viral content. Required: mandatory clearing through a filtration system and continuous disinfection to achieve biological safety liquid.
Wells with large depths
Water with a low amount of viruses and bacteria, but with a large number of different chemical and mechanical impurities (iron, boron, lead, manganese, etc.). Another disadvantage of water from the depths is its high stiffness and exorbitant amount of hydrogen sulfide.
Primary purpose filtration of water treatment system
Water purification system for homes is designed to improve the taste of the liquid, its cleaning from impurities, ensuring biological security.
Tankless water filters for cottages – multistage system, which can remove particles of sand, clay, metals, salts, bacteria and viruses, normalizing the chemical and biological composition of water, which after purification becomes fully suitable and safe for drinking water.
The basic rule of choosing the filtration system Before you purchase and install a purification system, it is IMPORTANT to make chemical and bacteriological analysis obtained from the well water.
Use to clean household water filter is impractical – such a facility is not conducting a full removal of impurities and does not normalize the chemical and biological composition of water.
Water purification system from the well is a staged process, comprising:
Mechanical cleaning of tube-well water
- mechanical cleaning;
- removal of iron;
Cottage water treatment involves the use of a mechanical coarse filter to clean the water for the garden with a drainage system. This decision will allow to abandon the regular replacement of the filter element, using backwash (intermittent pumping the clean water back with the leaching of trapped in the filter particles and wash them into the drain).
As filling in a mechanical filter is used granulated aluminum silicate or ceramic powder.
For the smooth operation of the mechanical filter is recommended to refresh the filling once in five to seven years. Why is it important to use a mechanical filter?
First and foremost, the system allows you to clean borehole water from solids that affect water quality in General and are a major cause of failure of sanitary equipment (in the case of particles in mechanisms).
Filters for deferrization of water
Filter for iron removal is an Important and necessary stage of water purification from iron for the garden, without which it is impossible to do because of the high concentration of iron salts, compounds of manganese in natural water.
The main element of the filter in these units are the granules of manganese dioxide – compounds acting as catalyst for the oxidizing reaction, when the compound of iron and manganese from a soluble state to drop out coarse sediment and are removed through the filtration system. Sediment is nothing like rust.
To maintain filter in working condition requires constant regeneration of the granules using a solution of potassium permanganate (potassium permanganate) when in the filtration system installed capacity with this solution. Completely replace the granules of the filter once in five to seven years.
What is the advantage of using iron removal filter?
In addition to iron and manganese compounds the filtration system removes hydrogen sulfide, also affect quality of water. The principle of removal is the reverse washing of the filter, by analogy with the removal of solids from the mechanical filter. Filters hardness and softening is Important in the process of purification – softening with a decrease in hardness salts, which are released into the water from limestone and are unable Sweeney: mechanical system, for example. Used for softening ion-exchange filter, the "launching" a chemical reaction of salts of rigidity, which under the influence of the reagent be harmless to humans. As reagents is the salt solution. Ion exchange filter also helps to remove from the treated water of heavy metals.
The most recent step the water passes through a carbon filter chemical cleaning. This type of filter is similar to household filtration systems pitcher type, where installed, carbon cartridges.
However, in contrast to the domestic, filters most often recovered, where not provided by the use of any reagents. The cleaning process takes place by the reverse flow of the already purified water.
What type of filtration system is best to choose?
You can use a mono filter, which was discussed above, but if you want to install a multi-purpose filtration system, the effectiveness of which will depend entirely on his performance.
Multi-purpose filtration system consists mainly of a carbon filter, which is able to hold only a certain amount of impurities and has a strictly specified by the manufacturer of the resource output.
No such systems are highly efficient and can be used as water purifiers for the house, which offers temporary or seasonal accommodation. The disadvantage of activated carbon filters is microbiological fouling, when within the coal cartridge over time, the use start to accumulate fungal and antibacterial growths, leading to significant deterioration of water quality.
To determine the type of filtration system it is reasonable to conduct a chemical analysis of artesian water, the results of which will reflect the indicators of hardness, iron content, lead, hydrogen sulfide, etc.
In addition to the chemical-biological analysis for a proper selection of filtration systems need to collect data about the residential home, number of occupants, usage of artesian water, water consumption in General.
All data should be provided to the company specializing in the sale and installation of filtration systems. Experts, having examined all specifications, the most suitable option, and completion filter. published
