Water Filtration Systems

In modern conditions is becoming particularly urgent task is to achieve the desired water quality.It may come to the end consumer from various sources.They act as artesian wells, mountain streams, surface water and sea water after desalination treatment.Thus it is necessary to make it transparent and odorless, not contained in the composition of pathogens, as well as impurities, suspensions of solid particles and dissolved substances causing sludge.Furthermore, it should control the content of the drinking water, domestic use and industrial use of harmful chemicals.Before feeding it requires the preparatory process comprising filtering the water diversion respectively.

water filtration methods

Filters are applied in the following cases:

• for demineralization and neutralize pollutants;
• for clarification from the silt and sand water - when taking it out of rivers and lakes;
• to bring to an acceptable quality of tap water;
• water, which worsened its characteristics during processing and use;
• for final processing before being returned to the natural cycle.

With a variety of water filtration remove suspended particles of debris, leaves, clay and sand, rust and slag to protect the water distribution network (pipes, plumbing fixtures and valves) from clogging and corrosion, the appearance of sediments in the form of insoluble plaque.

Modern water treatment and water supply systems to ensure clean and safe water are pursuing a comprehensive clean:

• passing through a water filtration system in the form of special cleaning modules containing filter layer (gravel and crushed stone, sand, anthracite, etc..) - sometimes in combination with a biological filtration (using anaerobic bacteria, which are grown on gravel);
• through cassette filters and mechanical filters with screen elements.

Besides mechanical treatment, there are also traces of water filtration methods:

1. Chemicals - their principle of operation is based on a chemical reaction.

The chemicals added to the water to remove impurities by means of their decomposition, neutralization or precipitate, and converting the delay filter.Chemical filtration

water effectively softens water, normalizes its acidity and iron content of various salts, manganese, free chlorine and organic compounds, bacterial contaminants.This method is not suitable for drinking water.

1. Physical methods:

• reverse osmosis - using polymeric membrane filters with tiny holes which pass only molecules of water and oxygen;
• ultraviolet radiation - effectively sterilizes the water, killing bacteria;
• thermo water - hardness salts are destroyed by boiling and precipitate.

1. Physical and chemical methods offer the advantages of physical and chemical methods:

• using flotation effect - for filtering wastewater through a slurry effluent gas is passed, the resulting foam should be removed;
• ion exchange method - through the filtration is a filling in the form of ion exchange resin.The chemical reaction changing the structure of water, it happens softening - hardness salts are precipitated and filtered out mechanically.This method is not suitable for drinking water;
• using electrocoagulation - under the influence of electrolysis occurs deposition of colloidal particles and suspensions.

Filtering equipment

In modern conditions is increasingly used multilayer filters for water treatment, consisting of several layers with specific functions, the water passes sequentially through the entire thickness of the filter layers.This treatment significantly increases the speed and efficiency of water treatment.

Today, the use of water filtration systems for houses and apartments is no longer a luxury.In the modern environmental situation experts strongly recommend the use of household filters for drinking water.

filters

home to decide what kind of water filtration system to buy, first and foremost, it is necessary to order the analysis of water from wells or water supply system - to determine the degree of saturation of impurities.You can choose on the basis of the results filtering installations for removing a variety of impurities, make drinking water clean and safe, and to protect domestic appliances and sanitary equipment from dirt, limescale and subsequent breakdowns.

sale presents a variety of filters for water purification:

• filter jugs - small and mobile filters that protect against certain types of pollution.They differ low price;
• flow filters that are installed on individual taps, as well as installed under the sink - provide requirements for purified water for several people.Quality of life and a cleaning cartridge is higher than in-filter jugs;
• integrated water filtration system for the house - a costly and complex systems, providing filtering of up to 99% of pollution.Among these manufacturers offer installation of multi-purpose water purification by reverse osmosis - for example, a water filtration system Atoll.

Such filtering includes:

• pretreatment in the form of water purification chlorine, pesticides and organic, mechanical impurities of up to 1 micron;
• passing through a semipermeable polymer membrane fine filter;
• final filtration through a carbon filter.

Flow filters to separate valve can be installed in any home.These systems are characterized by the best ratio of price and functionality, greatly improve the quality of drinking water, effectively cleanse it from various contaminants.The system includes a water filtration method is a three-level cleaning Geyser saves in soft water natural mineralization and hard - to effectively soften.Currently, this process is used by many manufacturers.

filters for wells

for well water is traditionally used natural bottom filtering drinking water through a layer of non-toxic and insoluble materials (gravel, crushed stone, sand, pebbles, schungite, jade, etc.) - they are placed atbottom of the well during construction.

In addition, wells are widely used for the bottom of the geotextile soil filters (polypropylene fibers), and cassette filters, the ability to deal with these types of contaminants such as pesticides and a variety of chemical impurities.

Water Filtration

pool pool Specificity is that required purification of fine dust, bacteria and microorganisms, as well as algae that cause algal blooms, organic substances.To maintain the level of sanitary and hygienic condition of the pool must be equipped with a filtration system.Purification of water in the pool of debris produced by a filter through which the water passes slowly.At the same time the water circulation pump maintains a pre-filter in the form of a basket with large cells for detention debris.

For pools following filter types are used:

• sand - with a filter bag of sand without clay additive.It depends on its grain litter filtration efficiency and filtration capacity.In such filters used quartz sand (grain size 0 is recommended, 45-0,55 mm) and glass sand.The presence of six or four-tap lets you wash the sand, without a replacement.When buying a sand filter should pay attention to the presence in the sales of replacement valves;
• multilayer filters - in the form of two or three layers of different grain mineral fillings, decreasing in the direction of water flow.First large debris is filtered out, and then a fine;
• cartridge - in a plastic or metal housing located petal replaceable cartridge that you want to change the extent of pollution;
• combined filters - for water disinfection and enrichment in the composition of water in the pool filtration systems use a variety of plant and allowing ozonize ionized water containing cartridges with bromine, chlorine or iodine.Such systems, depending on the design, can perform multiple functions - disinfection, concentration and filtration.

For home pools of small size (up to 10 m3) allowed the use of filters, cartridges, increasing the volume of water is recommended to use sand filters and water disinfection methods.
