Water treatment material Polyaluminium ferric chloride(PAFC)

Brief introduction:

Polyaluminium ferric chloride (PAFC) is made up of aluminum salt and iron salt coagulation hydrolyzing and become

a kind of inorganic polymer coagulants, based on the principle of synergies, join the elemental iron ion or three iron

oxide and other compounds containing iron composite is a new type of high efficient coagulant.

It combines merits for aluminum salt and iron salts of aluminum ion and iron ion form has improved significantly,

polymerization degree is greatly improved. Aluminum, iron coagulant respectively of the advantages of air flotation

operation, improve the concrete performance of polyaluminium chloride; For high and low temperature and low

turbidity water water purification treatment effect is particularly evident, needn’t add alkaline additives and other

coagulant aid.

performance:

1, fast hydrolysis and weak hydration. Dense alumem ustoum, sedimentation speed.Affected by the temperature

change is small, can meet the requirements of shear force in the process of flow.

2, solid product is brown, reddish brown powder, easily soluble in water.

3, which can effectively remove the aluminum ion in the raw water and remaining free aluminum ion in water after

aluminum salts coagulation.

4, wide applicable scope, drinking water, industrial water, water, sewage and industrial wastewater treatment, etc.

5, Less dose, treatment effect is good, cut down the cost of 10-20% than other coagulants.

6, using method and packaging purposes matters is essentially same as polyaluminium chloride.

features:
1, the dosage is far lower than the traditional flocculant,the water quality is good after purification.
2, the flocculation body is formed fast, precipitation is rapid, is bigger than traditional products processing capacity.
3, the alkalinity of the water consumption, less water lower PH.

technology classification:

1, drum-type poly aluminum chloride, general aluminum content, high water insolubles, used for sewage treatment.

2, frame type poly aluminum chloride has high aluminum content, low water insolubles, used in sewage treatment

and drinking.

3, spray drying, poly aluminum chloride has high aluminum content, low water insolubles , faster dissolve. used

for potable water and higher standards water treatment.

purposes:

Polyaluminium ferric chloride has widely scope of application: used in drinking water, industrial water, sewage

and industrial wastewater treatment, polyaluminium ferric chloride has obvious effect with all kinds of industrial

water and drinking water purification treatment.

Q: anybody here knows the difference of organic iron salt (ex. F.gluconate) vs inorganic (ex. F.sulfate)?: It it's organic, then the anion (the negative ion) is the conjugate base of an organic acid. If it's inorganic, then the original acid was inorganic (like H2SO4 making sulphates).

Q: How does inorganic salts maintain osmotic pressure and pH: PH ~ inorganic salts of carbonates bicarbonate, hydrogen phosphate / dihydrogen phosphate, can help regulate the pH value of the internal environment, even if the external environment Zoumu changes, the environment will not change too fast, there will be a Buffer room

Q: Inorganic salt of the inorganic salt function: Although inorganic salts in the cell content is relatively small, but there are many important role. Ca2 + is the animal bone and teeth (containing CaCO3) composition, and blood coagulation and muscle contraction has a regulatory role, if the content is too low, the animal will appear muscle twitch. K + is a variety of enzyme activator, for the plant starch and protein synthesis and animal nerve impulse conduction and muscle contraction also plays an important role. Fe is a component of hemoglobin and cytochrome, and iron-containing enzymes are indispensable when chlorophyll is formed in plants. Another example is Na + for animal heart beat, nerve excitement is indispensable. The various inorganic salts dissolved in the cells have a certain total concentration, such as human body fluid concentration of 0.9%, frogs of 0.65%, which for maintaining cell osmotic pressure, so that cells maintain a certain shape has an important role, too high or Too low will lead to cell due to water or dehydration to change the cell morphology. There are also a number of buffering systems in the body, which are a group which has a neutralizing effect on the added acid or base so that the pH does not change significantly and therefore plays an important role in maintaining the acid-base balance of the cells.

Q: Why plasma osmotic pressure and protein, inorganic salt content: The crystal osmotic pressure is determined by the content of inorganic salts; colloid osmotic pressure is mainly determined by the protein content, especially albumin.

Q: I will eat a boiled egg every morning, drink a box of milk before going to bed at night, to stop these things, eat only vegetables?: Strengthen exercise consumption.

Q: The lack of symptoms and food sources of several inorganic salts: Food sources of inorganic salts containing calcium Source: dairy products, beans, cereals, kelp and so on. Source: seafood, etc. Food of iron-containing inorganic salts Source: Fruits Containing iodine-containing inorganic salts Source (trace): seaweed, jellyfish, corn, mussels, etc. Zinc-containing inorganic salt food sources (trace): animal liver (viscera), fruit, peanuts, etc.

Q: The lack of three major inorganic salts can cause symptoms in the plant: Potassium: Stable stem to promote starch formation. Lack of performance: stems weak, easy to lodging, leaves the edge and the tip was brown, and gradually dry. In addition to these three types of inorganic salts, plants also require many types of inorganic salts.

Q: What inorganic salts are needed for seeds?: Phosphate, nitrogen, magnesium, calcium, iron, copper, and boric acid

Q: What are organic and inorganic salts?: Salt is a mineral from the Earth. Salts similar to iodized are extra munufactured and aren't fully typical. However salts like sea salt have the leat amount of processing. Some say that sea salt is healthier since it's he most traditional state of salt that you could get in mass production. I wolud must agree with them.

Q: Effects of Minerals on Plants: Root absorption of mineral elements is based on cell uptake. But the root of the absorption of mineral elements has its own characteristics. First, the roots of salt and water relative absorption. As the root of the salt and water absorption mechanism is different, the absorption is disproportionate. The second is that the root system is selective for the absorption of mineral elements. That is, some of the absorption of some ions, while the absorption of some ions with little or no absorption. The third is that single salt poison and ion confrontation. The general cationic toxic effect is obvious, the anion toxic effect is not obvious. In the single salt solution if adding a small amount of other valence of different metal ions in the salt, single salt poisoning phenomenon will be reduced or disappeared. This effect of ions is called ion confrontation. Generally in the periodic table of different groups of metal elements between the ions will have a confrontation. Plants as long as a certain concentration, a certain proportion of a variety of salt mixture in order to normal growth, this solution is called the balance solution. In the fertilization should be very careful.
