The chemical appears as a dark brown liquid. It is highly toxic to human beings and aquatic life. You should never touch it as it irritates the skin and its vapors may affect the eyes. However, it has a strong rusty smell that is noticeable from a far. It mixes with water.
Chemical application and strengths:
- The chemical is high reactive with other soluble metal elements in the water. Therefore, it is used for coagulation. In the process the iron anions attach to the negative element ions in water to form a precipitate or suspended solid. These solids can then be removed from the water during filtration. This is a common method of purifying drinking water to a high as 85% purity.
- In addition, it is used in wastewater treatment plants to precipitate phosphorus. Phosphorus is one of the major elements found in raw sewage that leads to eutrophication of large water bodies. Eutrophication is the process of enriching the water bodies with nutrients from outside the ecosystem. It often leads to the imbalance of the ecosystem as algae and other aquatic plants invade the water body in large numbers due to the presence of enough nutrients.
- Ferric Chloride is also used in treatment of raw sewage to prevent the production of hydrogen sulfide. Hydrogen Sulfide is a highly corrosive and poisonous gas that is produced after microbial breakdown on organic materials where oxygen is absent such as sewerage.
- Ferric Chloride is also used in sludge conditioning. This is the process by which solids in sludges area treated with chemicals so that the sludge can be dewatered. Essentially, these chemicals create compounds that sediment in or precipitate in the sludge allowing the water to be removed without losing any of the metal elements.
