DownloadWhat is the primary purpose of coagulation in water treatment?
Omdraaien
The primary purpose of coagulation is to destabilize and aggregate suspended particles in water to form larger particles called flocs, which can be easily removed through sedimentation and filtration.
What chemical is commonly used as a coagulant in water treatment plants?
Omdraaien
Aluminum sulfate (alum) is commonly used as a coagulant in water treatment plants.
What is the difference between flocculation and coagulation?
Omdraaien
Coagulation is the process of adding chemicals to water to destabilize particles, while flocculation is the gentle stirring process that encourages the formation of larger flocs from the destabilized particles.
What is the purpose of sedimentation in the water treatment process?
Omdraaien
The purpose of sedimentation is to allow flocs to settle to the bottom of a sedimentation basin, so they can be removed from the water.
What is the typical pH range for effective coagulation?
Omdraaien
The typical pH range for effective coagulation is between 5.5 and 8.0.
What is the role of filtration in water treatment?
Omdraaien
Filtration removes remaining suspended particles and microorganisms from water after sedimentation, improving water clarity and quality.
What type of filter media is commonly used in water treatment plants?
Omdraaien
Sand and anthracite coal are commonly used as filter media in water treatment plants.
What is the purpose of disinfection in water treatment?
Omdraaien
The purpose of disinfection is to kill or inactivate harmful microorganisms to ensure the water is safe for human consumption.
