Activated carbon is a substance which are frequently used in water treatment industry, can remove the smell and taste, colour, residual chlorine, colloidal and organic matter (

Synthetic detergents, pesticides, herbicides, pesticides, synthetic dyes, THMS, halide acetate, endocrine disruptors such as phthalic acid esters PAES)
, heavy metals (
Such as cadmium, chromium, lead, mercury, silver, nickel, etc. )

, radioactive substances, etc. , is the earliest and most widely used in water purification water purification materials.


active carbon in the water treatment industry development prospects
the influencing factors of adsorption, adsorption capacity and adsorption speed are the main indicators to measure the adsorption process.

The size of the adsorption capacity is measured by adsorption, the adsorption rate refers to the unit weight of adsorbent adsorption in unit time quality.

In water treatment, sewage needs and adsorbent adsorption speed determines the contact time.

Activated carbon adsorption ability is associated with the pore size and structure of activated carbon.

In general, the smaller the particle, the faster the pore diffusion velocity, the stronger the adsorption ability of active carbon.

Wastewater pH value and temperature also has effect on the adsorption of activated carbon.

Activated carbon under acid condition in general than in alkaline conditions have higher adsorption capacity.

Adsorption is usually exothermic reaction, so low temperature favors the adsorption reaction.

Of course, activated carbon adsorption ability related to the sewage concentration.

In a certain temperature, activated carbon adsorption quantity varies with the increase of concentration of adsorption material balance.


active carbon is a kind of special processing of carbon, with countless small porosity, large surface area, activated carbon surface area per gram is 500 -
1500m2。

Activated carbon has a strong physical adsorption and chemical adsorption function, but also has the detoxification.

Detoxification is the use of its vast size, will poison adsorption in microporous activated carbon and thus prevent the absorption of poison.

At the same time, the activated carbon can be combined with a variety of chemicals, so as to prevent the absorption of these substances.

Activated carbon adsorption of activated carbon adsorption is the use of a solid surface of active carbon adsorption of one or more of the substance in water, in order to achieve the purpose of purifying water quality.


active carbon filter material is the most main, the most used water adsorption materials (

Other adsorption materials are: neutral macroporous resin and macroporous Yin resin, zeolite and diatomite, etc. )
。

Activated carbon is made of coconut shells, fruit shell as raw material, through carbonization (
Burning furnace)
, activation,

In the column's activation furnace in 800 ℃ high temperature steam activation)

Washing, drying, crushing, screening, air separation, etc.

In the early 1930 s, people use activated carbon adsorption of phenol in waste water from coking plant, as a result, the application of activated carbon in water treatment has a history of nearly eighty years.

Recorded in 1862 Britain using activated carbon to purify drinking water.

Our country is also the earliest modern water purification activated carbon for water purification materials.

Can say, since the birth of water purifiers, activated carbon has been linked to water purification 'inseparable', was tight.


activated carbon filter can remove the water smell and taste, colour, residual chlorine, colloid, organic matter (

Synthetic detergents, pesticides, herbicides, pesticides, synthetic dyes, THMS, halide acetate, endocrine disruptors such as phthalic acid esters PAES)
, heavy metals (
Such as cadmium, chromium, lead, mercury, silver, nickel, etc. )

, radioactive substances, etc. , is the earliest and most widely used in water purification water purification materials.

General activated carbon filter, not only in domestic reverse osmosis pure water, and most of the ultrafiltration, such as ceramic, KDF, UV water purifiers, will use the activated carbon.

Activated carbon and KDF can remove residual chlorine in water, but KDF chlorine reaction and zinc ions (
Zn2 +)

, excess zinc may lead to water, but not for chloride with activated carbon in addition to this kind of worry.

Activated carbon in the activation process to form the various shapes of small hole, constitutes a huge surface area with adsorption, surface area, the greater the adsorption effect is better.

Demineralized water equipment can be stable and continuous production does not contain heavy metals such as calcium and magnesium ion demineralized water.

Used in laundry industry can be a lot of detergent, the dosage of softener saving.
Improve the quality of washing, avoid clothings extensive blond, hard.

Is to improve the quality of washing and washing enterprise indispensable necessary equipment
a,
in nature water natural water of the earth's atmospheric precipitation, surface water and groundwater categories, is widely distributed in nature, such as sea water, river water, well water.

All of the natural water pollution by people if not is not pure, because water has great mobility and strong ability to dissolve, contain a variety of soluble substances and impurities.
This water is not suitable for washing clothes.

Water is the water washing medium, fabric washing, prewash and main water washing, bleaching, and a series of process must be water.
Good water quality can ensure that the washing quality.


2, the quality of the washing water
there is a quality standard of water quality.

The water quality standard is according to determine the content of the impurities in the water.

In the nature by a wide distribution salts such as calcium, magnesium, calcium magnesium salt is thus became a main component of hardness.

Generally the total hardness of water is the water containing the sum of calcium and magnesium ion concentration.

Hardness unit has with Germany, namely 1 100 water containing calcium carbonate as a degree in Germany.

Now with the tendency for L as hard water unit.
A German degree equal to zero.
357更易/ L。

Due to the amount and type of water containing impurities, general water into two types: hard water and soft water.
The hardness in 2.
9更易/ L (
8.
German degrees)
Over the water called hard water.


3, the disadvantages of hard water washing
with high calcium and magnesium ions of hard water and soap to wash clothes, soap, 30% of ingredients by calcium and magnesium ions and hard water consumption.

And combining the generated after the calcium and magnesium soap, is a kind of viscous substance does not dissolve in water, easily contaminated clothing, and it is difficult to remove, if remain on the clothes will make clothings extensive white, yellow, brittle.
So hard water is not suitable for washing clothes.


due to the benefits of soft water washing does not contain heavy metals such as calcium and magnesium ion in water softening, will not react with detergent and will not generate insoluble attachment, so that can save a lot of detergent, softener, bleach, while eliminating the adhesion of stains on clothing, also avoid the clothings extensive blond, hard.


4, soften water preparation
to soften the traditional preparation methods on the following two kinds:
1, the heating method: by heating the water boils again cold cold, precipitation, to remove the bottom with the upper scale less demineralized water.

This method need to consume large amounts of energy, and in the process of heating a scale precipitation, attached to the heating equipment such as boiler, etc. , will soon make its damage.


2, dosing method: namely the phosphide into the water, such as chemical sodium phosphate, to complex the water calcium and magnesium ions.

This method is first put reagent cost is high, the second is the environmental pollution is large, parts has banned the use of phosphate preparations.

The mainest is it can only be part of the lower water hardness, cannot completely remove the calcium and magnesium ions in the water.

The most advanced, economic and effective water softening manufacturing method is to use fully automatic water softener, by ion exchange method to completely remove the calcium and magnesium ions in the water, resulting in low hardness of demineralized water.

Five, softened water equipment,

the basis of the principle of ion exchange softened water equipment, by the controller, ion exchange of tank, regeneration salt tank.

Controller unattended, all-weather automatic operation.

Adopt new material cation exchange resin, has the exchange of large capacity, long life characteristics.

Ion exchange liquid tank and salt exchange box adopts domestic high quality products with sturdy beautiful shape, a full set of equipment has reliable operation, saving water, save electricity, low salt consumption and long life characteristics.

Can choose according to need water rate 1 t/H ~ 200 t/H of the equipment.
Very low softening water hardness & lt;
0.

03 tendency for L, fully meet the laundry water quality requirements.


steam boiler for softening water, according to the relevant provisions of the state in order to ensure the safe operation of the steam boiler water demineralized water must be used to prevent scale, fully automatic water softener to soften produced water hardness & lt;
0.

03 tendency for L, completely conforms to national standard GB1576 -
2001 the industrial boiler water quality requirements.

Technical supervision bureau and the labor security department acceptance of boiler room for essential equipment.


ironing equipment to use demineralized water steam generator, iron, such as the use of hard water in the process of ironing will produce scale, heating tube caused by burning, steam injection hole blockage, ironing clothes with white stains, light and so on.

When using softened water after these problems are solved.
