One study found that “after 180 days” of facilitating sulfammox and anammox in landfill leachates, “the nitrogen and sulfate removal efficiencies of 95.7% and 24.3%, respectively, were obtained” with sulfammox accounting for “27.5% of total inorganic nitrogen removal” and anammox accounting for “65.6%”.

Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.
As more aluminum sulfate is added, water pH decreases. At higher pH, the soluble species Al(OH) 4 − is present. In neutral pH ranges (6–8), the insoluble aluminum hydroxide (Al(OH) 3) occurs. As pH decreases further, the Al(III) ion remains present. [2] Maintaining optimal pH is important for the removal of phosphorus from water.
Barley straw, in England, is placed in mesh bags and floated in fish ponds or water gardens to help reduce algal growth without harming pond plants and animals. Barley straw has not been approved by the United States Environmental Protection Agency (EPA) for use as a pesticide and its effectiveness as an algaecide in ponds has produced mixed results during university testing in the United ...
3) and sulfate (SO 2− 4). As water passes through the anion resin the carbonate, bicarbonate and sulfate ions are exchanged for chloride ions. "Higher capacities can be realized by use of type II rather than type I strong base anion resins.

The condition indicates a high level of sulfate-reducing bacteria in the water supply. This may be due to the use of well water, poorly treated city water, or water heater contamination. Various methods exist to treat sulfur in water. These methods include Filtration of the water using a carbon filter (useful for very small amounts of hydrogen ...
