Question

How can we stop algal bloom?

Answer 1

Algal bloom:

1. Following the bacterial degradation of algae, the oxygen level in the water body decreases.
2. Increased nutrient levels in lakes, ponds, rivers, and coastal zones result in a significant increase in phytoplankton.

We can stop the algal bloom in the following ways:

1. Implementation of efficient filter ecosystems for nitrogen and phosphorus removal from runoff water.
2. Farming techniques should be rationalized through proper fertilization planning and the use of slow-release fertilizers.
3. Alternative animal husbandry practices are used to reduce wastewater production.
4. Improvements to the purification performance of wastewater treatment plants, as well as the installation of tertiary treatment systems to reduce nutrient concentrations.
5. Water oxygenation is used to restore ecological conditions by reducing the negative effects of the eutrophic process, such as oxygen scarcity and anaerobic toxic compound formation.
