Model Selection Of Polyacrylamide Flocculant

- Dec 05, 2016 -

Boyuan water purification materials technologies from polyacrylamide charged type, charge density, molecular weight, molecular structure, the use of polyacrylamide as a different type of choice.

1, the type of flocculant

Firstly, the wastewater quality Boyuan water purification materials technical department. According to the type of particles in the sewage, the flocculant is charged. The use of flocculant to capture the negatively charged inorganic particles, using flocculant charged to capture organic particles, through the experimental method to find more accurate charge type flocculant.

2, flocculant charged distribution density (ionic degree)

Boyuan water purification materials technical department according to the charge density distribution of charged flocculant, flocculant used in the least amount of cases, the number of obtaining the best flocculation efficiency required flocculant with positive charge or negative charge. Distribution of charge density and charge density distribution of sludge type, sludge is often a function of the organic content in the sludge, and the organic matter content and content often volatile, volatile content is higher, the higher the amount charged to the flocculant.

3, molecular weight

Boyuan water purification materials technology department the molecular weights were chosen as third indicators. According to the type of equipment used for dehydration treatment, the molecular weight is selected. For the centrifuge dewatering machine type: the molecular weight of the polymer better, for dewatering machine filter: low molecular weight to moderate molecular weight flocculants can meet the requirements, and can get a good account of water function.

4, molecular structure

Boyuan water purification materials technology department of molecular structure is chosen as fourth indicators. The molecular structure of the cationic flocculant is divided into: linear structure, branched structure, cross-linked network structure.

The choice of the type of flocculant has the rule to be found, as long as we carefully observe the law. In fact, each kind of wastewater has its specific that one or several kinds of flocculant can meet the conditions of flocculation or dehydration of sewage treatment.

 

Boyuan water purification materials technology department offers a variety of choice for site specific drug polyacrylamide, process equipment requirements, help you optimize the processing index.
