Understanding Coagulation Chemicals and pH Values
Coagulation chemicals are essential in water treatment processes, and their effectiveness can be influenced by the pH of the water. Below is a detailed explanation of the listed coagulation chemicals and their corresponding pH values.
Coagulation Chemicals
pH Value Categories
Correct Pairing
The best matching of coagulation chemicals to pH values would be:
Thus, the correct answer is b) 1. 4. 3. 2, as it matches the coagulation chemicals with their effective pH ranges.
Coagulation chemicals are essential in water treatment processes, and their effectiveness can be influenced by the pH of the water. Below is a detailed explanation of the listed coagulation chemicals and their corresponding pH values.
Coagulation Chemicals
- A) Alum: Commonly used in water treatment, alum is effective in a pH range of 6.5 to 8.5.
- B) Copperas: Also known as ferrous sulfate, copperas is effective in pH values around 6.5 to 8.5.
- C) Chlorinated Copperas: This is a modified form of copperas and works best in similar pH conditions.
- D) Sodium Aluminate: This chemical is effective in alkaline water, ideally at pH values above 8.5.
pH Value Categories
- 1) 8.5 and above: Alkaline water, suitable for sodium aluminate.
- 2) 6.5 to 8.5: Neutral to slightly alkaline water, suitable for alum and copperas.
- 3) Non-alkaline water: Generally below 6.5, not ideal for the above coagulation chemicals.
- 4) 3.5 to 6.5: Acidic water, unsuitable for these coagulation processes.
Correct Pairing
The best matching of coagulation chemicals to pH values would be:
- A) Alum - 2) 6.5 to 8.5
- B) Copperas - 2) 6.5 to 8.5
- C) Chlorinated Copperas - 2) 6.5 to 8.5
- D) Sodium Aluminate - 1) 8.5 and above
Thus, the correct answer is b) 1. 4. 3. 2, as it matches the coagulation chemicals with their effective pH ranges.
