Filter for water purification from iron: how it works, the device

Water iron removal - pressing problems. At higher concentrations of iron having a specific taste and a yellowish tint, iron bacteria develop. Independently purify the water from the iron is possible, but it is too time-consuming process.

Increased iron content - a major factor that reduces the quality of water. The negative impact of this substance on human health and the harm caused to domestic appliances, place high demands on the filters.

The use of such devices is an effective way to filter contaminants.

How the filter for water purification from iron

Household filters - a compact productive cleaning systems.

This transition material is carried out with the use of polymeric reagents without them.

This difference determines the classification cleaners into two types:

• reagentosoderzhaschie - using chlorine as the oxidant, ozone or manganese;
• reagentless - oxidation occurs under the influence of oxygen, which is dissolved, needs to iron molecule in the insoluble pellet.

Then, these insoluble particles precipitate flakes and filtered mechanically.

purification devices operating on the reagents that neutralize the adverse effects of iron, are divided into two subspecies:

• Sediment character unit;
• filters for cleaning aeration.

Sediment - a sealed container having a bottle shape. They are filled with backfill, performing the role of an absorbent. For this purpose, the substrate is often used, which sorbent aluminosilicate catalyzing the oxidation reaction.

The substrate is produced and requires regeneration. This process is performed automatically or manually, depending on the filter model.

The aeration cleaners water enriched with oxygen and iron contained in it is oxidized. These units operate under the liquid pressure function or without it. The difference is that when depressurised embodiment, water enters the tank through the nozzles, the spray effluent.

Aeration is carried out at a pressure which forces the automatic compressor. Oxidized harmful impurities is removed mechanically strenerom. Aeration apparatus qualitatively obezzhelezivayut liquid.

Water filter pattern with high technical and technological characteristics economical.

Filter apparatus for purification of water from iron

On the market there are a large number of models of filters to get rid of excess metals.

Selection of modification depends on the requirements for the quality of the instrument, and the financial capacity of the consumer.

Graduation classes household cleaners to water:

• jug - principle of operation consists in a liquid overflow from the reservoir into the container through a replaceable filter cartridge;
• installation type "near the car wash" - the filter is located next to the sink and connects to the faucet with a flexible hose;
• Stationary filters - are embedded in the water system, the sink imposed separate tap for purified liquid.

Stationary flow-through device distinction and reverse osmosis:

• Flow - after several purification steps iron impurity is removed mechanically.
• With reverse osmosis - possess a thin semipermeable membrane permeable only to molecules of water and the remainder is discharged into the sewage outlet.

Water purification equipment removes iron from other harmful or hazardous substances.

Filters are divided into such groups according to the degree of filtration:

• rough - the device for mechanical cleaning, retaining all the slurry is installed in the water distribution pipes. It is auxiliary, eliminating the rust, sand and heavy metals;
• fine - removes heavy metal oxide, salt crystals, chlorine, dissolved in a liquid, the undesired ions;
• biological - is in addition to the fine filtration devices, eliminating the harmful bacteria.

Water softener and removing nitrates, sulfates, magnesium ion mounted auxiliary cleaner. they work on the principle of change of unnecessary ions neutral ions.

Cheap variation cleaning are the adsorption model. Cartridges with activated carbon reliably keep unnecessary chemicals.

Sometimes cleaning system equipped with a UV lamp that kills germs. Installing sterilize and disinfect the liquid.

Sterilizing effect have iodine ions, silver, ozone treatment. To dead microorganisms have not been put into the water after a charcoal filter layer.

Each user, based on the requirements to the quality of the cleaning system may itself choose suits his set of filter elements.

Advantages and disadvantages

Lineup household cleaners available in a wide price range. Democratic costs have jug devices. Filters installed near the sink, are classified as low-cost devices.

Comparative analysis of the modifications:

• Jug - simplicity and ease of use, does not require a connection to the water supply. Disadvantages are the low efficiency, short life of the filter cartridge, a small volume of purified liquid at a time. Perfect for the office, a country house, a rented apartment.
• Installation close to the sink - for shallow filtration. Advantages - portability, no need for a separate tank for the purified liquid. The disadvantages include a small resource, low efficiency, the need for connecting and disconnecting after work. Not a bad option for one person. A family of several people better opt-mobile devices.
• Flow-through installations - in acceptable conditions with low iron concentrations.
• Filters RO - purified liquid at 99%, is obtained completely pure water, odorless and tasteless. The cost of such models is high, but it is justified by the quality of cleaning. The relatively poor performance does not allow water treatment for technological needs.

For the purification of drinking water is considered a universal reverse osmosis membrane filter.

Before buying a filter is desirable to perform chemical analyzes of fluid consumed by a specialized laboratory. Determine the exact concentration of undesirable impurities to the acquired filter is failed to stop the chemical composition of the fluid.

Next, the user needs to define the brand. This will help to customer reviews on the websites of manufacturers of products or online stores, consulting sales consultants. Purchase is recommended in specialized outlets.

How to use the filter for water purification from iron

For maximum performance, resource generation backfill should comply with such recommendations:

• observe the temperature regime, regulated by the manufacturer in the instructions;
• regularly substrate regeneration activities;
• the pressure in the water system should be under pressure from three atmospheres.

Performance water treatment system will be higher if:

• do regular washing;
• raw liquid of good quality;
• observing precautions.

Frequency of washing the membrane depends on the degree of contamination of the source liquid. This period is about 10 days.

All filters should be changed in time. Depending on the manufacturer filter life from quarter to a year.

Poor quality of the initial liquid is desirably preliminarily purified by sedimentation. Oxides, iron-containing chemical elements are deposited on the vessel walls.

During the life of the filtration quality is not degraded to completely deplete the resource. Products retain their properties after the declared end of the warranty period.

Before long periods of time the product is washed, dried and stored in a clean place without direct sunlight and heat flows.

Filtering jug washed generated cartridge change, the filter member held submerged in the liquid.

Precautionary measures

Prior to use, check the expiration date zasypnyh chemicals. In operation, the chemical elements are accumulated on the filter surface do not pass through the membrane pores. This layer hinders the work of the cleaner and prevents the free flow of water.

Read the protective devices and washed membrane under a gentle stream of water with a sponge. Do it carefully, because the membrane is a thin film. Reckless behavior will bring the device out of operation.

In the membrane should not prevent warping:

• disassemble the filter element;
• blown through the nozzle or hose;
• wipe with a hard cloth;
• connect the tube to the water supply.

It is undesirable to allow the drying of the filters, they have to pass the required amount of liquid, regulated Product Data Sheet. Otherwise they lose their original qualities.

Careful handling of the water purifier ensures its durability.

malfunctions

The water purification device to work well, the more complicated design and manufacturing process.

Possible faults reverse osmosis equipment and solutions are presented below.
Slowly typed water:

• checked the cartridges clogging degree of visual - appearance;
• checked lifetime;
• checked pressure values ​​at the input parameters to the membrane;
• at constantly low pressure pump set;
• under permanent high pressure apparatus equipped with a pressure reducer.

If the unit purified water drains into the sewers, check:

• four-way valve - it should stop the water supply when tap overlapped on the storage container, during the further feeding replaced;
• check valve - discharge into drainage water must cease when filling the container for purified liquid;
• pressure - outlet to the membrane.

Bad taste, peculiar taste of the water caused by:

• stagnant water - drained two or three glasses of water, or set mineralizer;
• missed deadlines replacement post-carbon cartridge;
• incomplete use of the pressure accumulator resource;
• lack of water in the tank upgrade.

Low pressure tap raise the following measures:

• adjust the work tank;
• adjust the pressure - it should not fall at the opening of an additional tap.
