Features of the membrane filter for water

In the modern world today can not do without high-quality water.To use this water, you can go two ways: purchase every time bottles with purified water or install a filtration system in the apartment.

Water purification systems are different.Gained particular popularity membrane filters for water purification.They allow you to perform the purification of the water quickly and efficiently.And filters cope with the tasks of any complexity and purified water varying degrees of contamination.

main element, which is located inside the filter - a special membrane.Filter works on the principle that it passes water through the membrane (which comprises several layers of material resembling cloth) which keeps all unwanted impurities to the human body in the water.

Methods for cleaning

sale presented filters for membrane-type water, which purify the water by such methods:

• microfiltration;
• nanofiltration;
• dialysis;
• reverse ostmos.

Depending on which method of treatment you choose, set the corresponding membrane (filter).To select the type of the membrane, it is necessary to determine its characteristics.

Features membranes

Depending on the desired result, such filters have characteristics:

1. ability to delay or split."Selective" type membrane filter.To get high-quality water, it is necessary to selectivity had the highest value.It has a different value for each substance.Determine the selectivity of a special table or directory.It has the exact name and rarely limited to the top and bottom.Additionally, there are ways that enable to calculate the value of each component individually.
2. Performance in specific gravity filter.This characteristic is calculated solely on the table (or directory), but only purified water.To find out the real value, it is necessary to carry out the experiment.But, as practice shows, it is possible on the basis of the initial parameter to know the working range.In most cases it does not exceed the performance of the filter, having a filler material, even if the boot is used for checking piroloks.
3. filter strength for mechanical characteristics.The characterization of membranes for use under mechanical stress and vibration (when the pump is turned on), there is the force of friction or flow occurs turbulent strain).In addition, the strength of the membrane plays an important role in the assembly system.Taken into account this figure, when you need to choose how to install the system.
4. Chemical resistance.This feature must be observed when selecting a system, it is responsible for the filter bed resistance to aggressive environments and provides a reliable barrier to acids, alkalis and detergents.
5. stability filter for biological indicators.It protects the membrane of microorganisms, which often collect on the surface.
6. resistance to high temperatures.
7. Service life of the filter.This figure depends on the filter operation, its regenerating modes, conditions during periods of inactivity.Membrane filters are far superior to other cleaning installation with boot cleaning materials.
8. Compliance with sanitary norms.This indicator is important in the food and medical industries.
9. Unlimited storage period of the membrane, if it is not used.This applies to the term membrane storage that are not being exploited.Even at rest they can accumulate bacteria and microorganisms, each layer of the membrane can dry out and adhere to deform.Therefore, the filter layer should be stored in sealed containers or dry (if this item is prescribed in the instructions).
10. cost.This characteristic reflects the value of the membrane towards the total cost of the entire system.Buy a membrane filter for water at a high price will be more difficult, even if the membrane is a ceramic spraying and will last much longer.
11. Disposal.There are several ways of recycling, each described in detail in the operating instructions of the filtration unit.

Application Method

membrane filter for water depending on the type of the cleaning installation has different ways of stacking.There are such types:

1. Ploskokamerny filter element "filter press".
2. tubular filter elements.
3. Spiral roll or water purification elements.
4. membranes arranged in the form of fibers and having a cavity inside.

Each membrane filters have different coefficients of water flow distribution and pressure.

If a method of microfiltration of water, then it is better to choose plants with a system of "filter-press".She imeyuschet ploskokamernye Filter elements or dosing pumps.Such devices have two membranes (flat), in which the distance is filled with drainage material.These systems are installed in places where the need for water of high quality is low, due to their low productivity.

also in water purification method "Ultrafiltration", set units, equipped with tubular filter elements, which further contribute to the softening of water.Purification plants installed inside the porous tube (diameter up to twenty-five millimeters), with a thin layer of membrane material.

systems that are equipped with the method of "reverse ostmos" is set in large enterprises.cleaning system is a roll type having a flat plate frame and presented in the form of a spiral.

In addition, the numerous reviews, membrane filters for water set out in the "fiber-type" devices have a high popularity.

Frequently Asked Questions

Before you a large selection of different water treatment systems.Which to choose?How it will work and what kind of water you drink?To avoid any doubt, if the membrane water treatment is needed, respond to frequently asked questions:

1. filter composition.It consists of several layers of a semipermeable material.Layers have a firm connection.Water flows through the membrane, which purifies water.
2. membrane is able to remove bacteria?Yes, definitely, because the size of the diaphragm aperture has a smaller diameter than the size of bacteria and viruses.
3. Purified Water has a specific taste?In fact - the major changes will not happen.Water would have a taste, it was before the treatment, but slightly different, depending on how many membranes installed.For example, if the system is able to treat up to 95 percent of the water from impurities, then the water will have the same taste as distilled or spring, which have a low percentage of minerals.
4. Does the purified water to the taste of food?On the contrary, membrane filters retain elements of "masking" the real taste of the water.This also applies to cooking - especially drinks.If you are using clean water, if possible, instead of a spoon of coffee put half, the flavor and aroma of the drink will be bright.On the water, which has gone clean through a membrane filter prepared cocktails and juices.
5. After purification of water and nutrients go?Most minerals that are essential to the human body, it receives together with food.Therefore, if the water flow is not just one percent of the minerals - nothing bad will happen.Also keep in mind that tap water is not mineralized, because it comes from rivers and reservoirs, where more contaminants than beneficial minerals.
6. Where can I install the cleaning unit?As a rule, a water purification system installed in the kitchen under the sink.Outside output tap for fresh water.The installation kit includes the mounting kit.
7. system maintenance requires certain skills and knowledge?Perform replacement filters can be yourself.About once every six months, the membrane must be replaced with new ones.
8. When to replace the membranes?If you notice that the plant began to produce less water or taste began to change, then it is time to replace the filter.Typically, during normal operation, and timely replacement of filters, the membrane can be replaced by two or three years.

Factors affecting water quality

Depending on certain points, the quality and quantity of water may vary:

1. pressure.If the pressure is large, then the quality and amount of water will be higher.
2. temperature.To purified water, it is necessary that the temperature was not lower than 24 degrees.If it will decrease significantly (e.g. up to five degrees), it can significantly reduce productivity.
3. Dirty water can affect plant operation.If the water is heavily polluted, and the system pressure is normal - you can count on good water quality.
4. membranes.They may have different qualities: some have a high performance, others - a high degree of purification.
