What are the ways to follow to control phosphates in pond?
The aluminum sulphate is commonly called alum which has an excellent role in lake water management. Considering the benefit of alum, it helps control phosphates in pond by using the method of precipitation. It forms a heavy particulate than water which is called a floc which further helps to control the phosphate content in pond or lake water. Following this, the floc creates a barrier that gives back the phosphorus release from the water. Policy issues relating for use of alum The policy helps check whether it is suitable for aquatic life or humans It helps maintain the correct balance of alum as it will be suitable to handle eutrophication versus the approach of the method to eliminate the causes Is it safe to use alum? The alum or aluminum sulphate used in lake water and when added to water, it forms aluminum ions which gets hydrated. In the method of hydrolysis, the hydrogen ions liberate and it lowers pH of the water. This converts to solid precipitate which forms to a floccule
