How can you coagulate dead suspended algae in ground swimming pool?

1. Chemical Coagulation:

This method involves adding a coagulant, such as aluminum sulfate (alum) or ferric sulfate, to the pool water. The coagulant reacts with the suspended algae particles causing them to clump together, making it easier for them to be filtered out.

2. Flocculation:

Flocculation aids in the coagulation process. It involves adding a substance, known as a flocculant, like polyacrylamide. Flocculants help bind the coagulated algae particles, forming larger and heavier clumps, making them easier to settle.

3. Filtration:

Once the algae particles are coagulated and flocculated, they can be removed by the pool's filter system. Backwash the filter regularly to prevent clogging and ensure efficient filtration.

4. pH Balancing:

Maintaining a proper pH level in the swimming pool is crucial. An ideal pH range is between 7.2 and 7.8. When the pH is too high or too low, coagulation may not be efficient.

5. Shock Treatment:

Regularly shocking the pool with a chlorine-based shock treatment can help kill algae cells and make coagulation more effective. However, follow proper instructions for chlorine shock treatment to avoid excessive levels.

6. Clarifying Agents:

Clarifying agents, such as chitosan or polyDADMAC, can enhance coagulation and flocculation. They work by attracting and binding the suspended particles, making them more effectively removed by the filter.

7. Proper Circulation:

Ensure that the pool water is adequately circulating. Good water circulation helps distribute the chemicals throughout the pool, maximizing their effectiveness in coagulating the algae.

8. Patience:

Coagulation and flocculation processes can take a while, especially for larger swimming pools. Give it time for the coagulated particles to form and settle before expecting crystal clear water.

Remember, preventing algae growth in the first place is the best approach. Regular pool maintenance, including cleaning, proper chemical balance, and sanitization, can help prevent algae formation.
