Algal Blooms in Drinking Water Reservoirs - LG Sonic

Frequent outbreaks of algal blooms are degrading water in drinking water reservoirs worldwide, making the water unusable. Algal blooms can sometimes be so massive that they are visible from outer space. Rising temperatures, prolonged water stagnation, extreme weather and increased runoff of nutrients from urban and agricultural lands are all compounding the algae problem.

This blog post discusses the causes and impact of algal blooms in drinking water.

1. Constructing wetlands with fast-growing plants to intercept the nutrient-rich run-off may help as the plants will consume the nutrients before the run-off reaches the water body. The advantage of this method is that plants grow fastest in warm sunny weather, exactly the sort of weather that promotes eutrophication, so this means that under such conditions the wetland plants consume the nutrients at a higher rate thus greatly minimizing the possibility of eutrophication

2. Not much any of us can do about sunspots/solar minimums. Earths natural cyclical event are way beyond man. But if the problem is algae then using an RNA microbe will clean up all blooms, stagnated water, and purify it at the same time.  Even the worst waste water can be cleaned ready to be declared potable.

    

3. Mixing of reservoir water by mixers is found to be suitable at some places as it minimizes stagnation. In conventional treatment Chlorine-di-oxide and small amount of chlorine or ozone can immobilize algae cells without bursting the skin. This prevents intra-cellular matter to escape out (which has THM forming potential). Alum and P.E. are necessary to entrap these particles.  Tapered flocculation followed by Tube settlers have proven to be effective to remove such algal floc.
