2. Algaecide - Wikipedia

   en.wikipedia.org/wiki/Algaecide

   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. Reactive oxygen species production in marine microalgae

   en.wikipedia.org/wiki/Reactive_oxygen_species...

   There are three main reactive oxygen species: the superoxide anion (O 2 −), hydrogen peroxide (H 2 O 2), and the hydroxyl radical (OH•). The superoxide anion is formed directly from the one-electron reduction of molecular oxygen. [29] Hydrogen peroxide is then formed from the disproportionation of the superoxide anion. This reaction occurs ...

4. Water aeration - Wikipedia

   en.wikipedia.org/wiki/Water_aeration

   Circulators are commonly used to mix a pond or lake and thus reduce thermal stratification. Once circulated water reaches the surface, the air-water interface facilitates the transfer of oxygen to the lake water. Natural resource and environmental managers have long been challenged by problems caused by thermal stratification of lakes.

6. Advanced oxidation process - Wikipedia

   en.wikipedia.org/wiki/Advanced_oxidation_process

   Hydroxyl radicals are produced with the help of one or more primary oxidants (e.g. ozone, hydrogen peroxide, oxygen) and/or energy sources (e.g. ultraviolet light) or catalysts (e.g. titanium dioxide). Precise, pre-programmed dosages, sequences and combinations of these reagents are applied in order to obtain a maximum •OH yield.
