True or False: Chemical coagulants can attract negatively charged particles.

Chemical coagulants play a crucial role in water treatment processes, particularly in the removal of suspended particles from water. Most particles in water, including silt and organic matter, often carry a negative charge. Chemical coagulants, such as aluminum sulfate or iron salts, carry a positive charge, which allows them to effectively attract and bond with the negatively charged particles. This agglomeration process helps form larger clusters known as flocs, which can then be easily removed from the water.

The properties of chemical coagulants mean they are specifically designed to neutralize the negative charge of particles, making aggregation possible. Therefore, the statement is true; chemical coagulants can indeed attract negatively charged particles, facilitating the clarification and purification of water. Understanding this principle is fundamental for operators managing water treatment facilities, as it impacts the efficiency of coagulation and subsequent filtration processes.
