Molecular weight and charge density: how to affect the treatment effect of cationic polymers
In water treatment applications, the performance of cationic polymers (such as PolyDADMAC, cationic PAM, etc.) does not only depend on whether they are cationic or not, molecular weight and charge density are the two core parameters that determine the treatment effect. Understanding the mechanisms of these two factors can help achieve higher processing efficiency, lower dosage, and more stable operating results in practical working conditions.

Should flocculants be added before biochemical treatment? 3 core indicators to help you make an accurate judgment.
In wastewater treatment processes, pretreatment prior to biological treatment is a critical step for ensuring the stable and efficient operation of subsequent biological systems. The decision to add flocculants at this stage should not be based on experience alone; it hinges on a scientific analysis of the influent water quality. By mastering the following three key assessment indicators and combining them with pilot-scale testing, precise decisions can be made while selecting the most suitable flocculant type.

Industrial wastewater treatment effect: How to achieve standard discharge?
Industrial wastewater treatment is a complex system engineering. It is necessary to select appropriate treatment processes and reagents according to the specific wastewater quality, and to do a good job of operation management. PAM is a commonly used flocculant in industrial wastewater treatment, which can effectively improve the treatment effect. Choosing a high-quality PAM supplier can provide reliable guarantee for industrial wastewater treatment.

Understanding pH Value in One Article: The “Acid-Base Balance Code” in Wastewater Treatment
pH value is a core indicator for measuring the acidity and alkalinity of water bodies, with a range of 0-14. Essentially, it represents the negative logarithm of the hydrogen ion concentration in a solution. When pH=7, the water body is neutral; pH<7 indicates acidity, with lower values indicating stronger acidity; pH>7 indicates alkalinity, with higher values indicating stronger alkalinity. In the entire process of wastewater treatment, pH value is not simply a "label for acidity and alkalinity", but a key control parameter that determines treatment efficiency, chemical effect, and system stability, directly affecting the progress of chemical reactions and microbial activity.

Should flocculants be added prior to biochemical treatment? Three core indicators to help you make an accurate assessment.
The decision to add flocculants prior to biological treatment hinges on a comprehensive assessment of three key indicators: ‘settling properties of suspended solids, COD composition, and total phosphorus concentration’. The key to determining the optimal chemical type and dosage lies in conducting ‘cup tests’: these simulate actual plant conditions to observe floc formation rate, floc size, and supernatant clarity under different chemicals and dosages, thereby establishing a precise dosing regimen. This approach ensures effective pretreatment, reduces the burden on the biological system, avoids chemical wastage, and achieves the optimal balance between pretreatment efficacy and operational costs.

How to calculate PAC dosage for wastewater treatment? Read this to find out!
Hey there, wastewater treatment chaps! Does calculating PAC (poly aluminium chloride) dosage feel like tackling a mind-boggling maths problem, leaving your brain in knots? Fret not, today we'll break down this dosage calculation – guaranteed to make it crystal clear! First, think of PAC as a ‘miracle cure’ for treating wastewater. The dosage must be spot on, or the problem won't be solved. Calculating PAC dosage is like cooking for a fussy child—you need to figure out their ‘appetite’ first.
