Is the Demand for Water Treatment Flocculant the More Efficacy is Good?
April 29, 2024
The first and more important is the impact of water treatment flocculant demand on flocculation efficacy. As a chemical agent, there are many factors affecting the performance of water treatment flocculants, the main factors affecting the configuration of pharmaceutical products are: water treatment flocculant demand, characteristics and structure, mixing speed and time, PH value, temperature and other factors.
In general, the flocculation effectiveness will increase with the increase in the amount of water treatment flocculant, but too much water treatment flocculant again to become a stable colloid; better demand is based on the content of suspended solids through specific experiments.
Water treatment flocculants: separation methods and process design on flocculation performance to the inorganic flocculants and organic polymer flocculants composite use of Polyaluminum Chloride and Polyacrylamide: in general, in the process of removing solid particles and oily wastewater in the treatment of raw water, the polymer organic water treatment flocculants are effective, the amount of additive is generally small, but if used in conjunction with the inorganic flocculants, the results are good. The combination of organic flocculants with inorganic flocculants is to obtain larger particles of water treatment flocculants and to coagulate or absorb oil droplets. The other is the chemical substance itself, Water Treatment Chemicals flocculants characteristics and structure of the flocculant effect on the flocculation effect to. Linear structure organic polymer water treatment flocculant has good flocculation efficacy; cyclic or branched chain structure is ineffective; organic polymer water treatment flocculant, polarity, hydrophilicity, charge characteristics, charge neutralization ability, the adsorption of colloidal particles and chemical reaction is different. Containing many functional groups, the charge density is too high; containing fewer functional groups, the charge density is too low, not conducive to charge neutralization.
In the test there is also a factor that can not be ignored is water treatment flocculant efficacy by the external influence is also critical: stirring speed and time: the speed is particularly fast, too long: the large particles of solids are broken into small particles, and the precipitable particles are broken into particles that can not be precipitated. Uneven distribution of water treatment flocculant concentration is not conducive to the action of water treatment flocculant.PH value: PH has a great influence on the potential of colloidal particles' surface charge, and the characteristics and action of water treatment flocculant. When the temperature is high, the chemical reaction rate is too fast, forming a small flocculation; low water temperature reaction rate is too slow, the hydrolysis time increases, affecting the amount of water to be treated, and the high viscosity tearing water treatment flocculant will also make the flocculation smaller.
