Main application of cationic flocculant
1, as flocculating representative, primarily utilized in commercial solid-liquid separation procedure, consisting of settlement, information, concentration and sludge dewatering innovation, application of the primary markets are: metropolitan sewage treatment, paper market, food processing, petrochemical market, metallurgical market, processing market, coloring market and sugar market and all sort of commercial wastewater treatment. Utilized in metropolitan sewage and meat, poultry, food processing wastewater treatment procedure of sludge rainfall and sludge dewatering by its natural colloid electrical group of sludge unfavorable charge neutralization and exceptional polymer bridging coagulation function, triggering colloid particles collected into large pieces of floc, separated from the slurry. The impact is apparent and the dose is little.
2, in the paper market can be utilized as paper dry strength representative, retention representative, filter representative, can considerably enhance the quality of paper, expense conserving, enhance the production capability of paper mill. Can straight and inorganic salt ions, fibers and other natural polymers electrostatic bridge impact to boost the physical strength of the paper, lower the loss of fiber or filler, accelerate water filtering, boost, assist to remain, assist to filter, can likewise be utilized for white water treatment, at the same time, in the process of deinking can play a substantial flocculation result.
3, fiber mud (asbestos-cement items) can make the forming of asbestos-cement items drain is enhanced, so that the strength of asbestos piece is enhanced; In the insulation board, the mix of additive and fiber can be enhanced.
4, in mining, coal preparation market can be utilized as mine wastewater, coal cleaning wastewater information representative.
5, can be utilized for coloring wastewater, leather wastewater, oily wastewater treatment, turbidity elimination, decolorization, in order to fulfill the discharge requirement.
6. In the filtration of phosphoric acid, it is practical to the separation of plaster in the damp phosphoric acid procedure.
7. Flocculant for water treatment in water supply with river water sources.
8 flocculant polyacrylamide dissolution approach and storage conditions.
The list below aspects ought to be thought about in the choice of concentration:.
Estimation of time in various seasons:.
B. When the molecular weight of the polymer is extremely high, it is advised to blend it with a little thinner (such as 0.1%).
A. It is advised that the mix be somewhat more powerful (e.g. 0.3%) due to the little pot and big everyday dose.
Polyacrylamide is a water-soluble polymer. In general, granular polyacrylamide can be kept in a dry and cool location for more than 2 years. After the option is prepared, its storage time is extremely minimal. Typically speaking, when the service concentration is 0.1%, the non-anionic polymer service does not go beyond one week; Cationic polymer service does not go beyond one day. The stability of the service is associated with the concentration, the thicker the service (such as 3% -5%), the longer the storage time. Nevertheless, 3% -5% of the option can not be straight treated with sewage, and must be watered down prior to usage. Cationic services are steady at PH listed below 5, however quickly stop working due to hydrolysis at PH above 6. It is more conscious iron and calcium and magnesium ions than anionic polymers.
1. In summer season when the water temperature level is high, unfavorable and cationic polymers require to be stirred for about 1 hour, non-ionic polymers require to be stirred for about 2 hours;.
2. When the water temperature level is low in winter season, the unfavorable and cationic polymers require to be stirred for about 1.5 hours, and the non-ionic polymers require to be stirred for about 3 hours;.
3. The greater the preparation concentration, the quicker the polymer dissolution rate. Irregular or insufficient dissolution will impact the result of use.
Iron ion is the driver for the chemical destruction of all polyacrylamide, so when preparing, moving and saving polyacrylamide option, iron ion need to be prevented as far as possible. The devices in contact with the service is ideally made from unembroidered steel, plastic, fiberglass or carbon steel with a painted surface area.
