Plastic additives are substances incorporated into polymer formulations to impart desirable characteristics that enhance their functionality and performance. They can be broadly categorized into several types plasticizers, stabilizers, fillers, colorants, and performance additives.
4. pH Adjusters Maintaining the right pH level is crucial in closed loop systems. pH adjusters, such as sodium hydroxide or sulfuric acid, are used to optimize conditions for other treatment chemicals, enhancing their effectiveness.
Another important application of chemical dosing is coagulation and flocculation. In this process, coagulants like aluminum sulfate or ferric chloride are added to the water. These chemicals bind with suspended particles, forming larger aggregates or flocs that can be easily removed during sedimentation or filtration. This step is particularly important in treating water from surface sources, which often contains high levels of turbidity due to silt, clay, and organic matter.
