Ferric Chloride
1. Coagulation and Flocculation:
Ferric chloride is a strong coagulant, meaning it destabilizes suspended particles in water, causing them to clump together.
These clumps, called flocs, are larger and heavier, making them easier to remove through processes like sedimentation (settling) or filtration.
2. Wastewater Treatment:
Ferric chloride is commonly used to treat wastewater from various industrial and municipal sources.
It helps remove suspended solids, organic matter, and heavy metals, leading to cleaner effluent.
3. Drinking Water Purification:
Ferric chloride is also employed in the purification of drinking water.
It aids in removing turbidity (cloudiness) and other impurities, producing clearer and safer drinking water.
4. Phosphorus Removal:
Ferric chloride is particularly effective in removing phosphorus from wastewater.
Phosphorus is a nutrient that can cause eutrophication (excessive nutrient enrichment) in water bodies, leading to harmful algal blooms.
5. Sludge Dewatering:
Ferric chloride can be used to dewater sludge, which is the solid waste generated during water and wastewater treatment.
Dewatering reduces the volume of sludge, making it easier to handle and dispose o
