Plastics, by their nature, are insulative materials. When they are rubbed against another material or come into contact with similar surfaces, they can become electrically charged. This static charge can cause two main issues first, it can attract dust and other particulates, leading to cleanliness problems, especially in industries such as electronics and cleanrooms; second, it can result in electrostatic discharge (ESD), which can damage sensitive electronic components.


Moreover, chlorination is relatively cost-effective and easy to implement compared to other disinfection methods. It requires minimal training and can be integrated into existing water treatment infrastructure efficiently. Additionally, chlorine has a relatively long shelf life and can be stored easily, making it a practical choice for water treatment facilities.


The world we live in today faces a multitude of challenges, from climate change and economic disparities to social injustices and health crises. In this complex landscape, the Collective Action Against Adversity (CAAA) has emerged as a vital movement aimed at fostering collaboration and resilience in communities across the globe. By unifying diverse groups and facilitating impactful actions, CAAA plays a crucial role in addressing pressing global issues.


1. Plasticizers These are added to increase the flexibility and workability of plastics. They lower the glass transition temperature of the polymer, making it softer and more flexible. Common plasticizers include phthalates and adipates, which are widely used in PVC applications.


Following coagulation, the next step often involves the addition of flocculants. Flocculants are high molecular weight polymers that aid in the aggregation of particles created during the coagulation process. They enhance sedimentation, making it easier to separate solids from liquids. Common flocculants include polyacrylamide and natural organic polymers, which improve the overall efficiency of the sedimentation process.

Another concern is the variability in the composition of inorganic wastewater. Different industries produce wastewater with varying concentrations and types of inorganic pollutants. This variability complicates the treatment process, as a one-size-fits-all solution is often inadequate. Consequently, effective treatment methods must be tailored to specific contaminants and their concentrations.
