When water is stagnant, has a high temperature or a high concentration of Nitrates and Phosphates, an algae bloom might occur, which can cause several problems. Blue-green algae growth, also known as cyanobacteria, can cause a foul odour to the water, a layer of scum on the surface and even pose a health risk. Green algae may colour the water green, look unclear and plants can die. Therefore an algae problem is often unwanted and algae control is desired.
1 An alcoholic beverage made by distillation rather than by fermentation. 2  A rich broth resulting from the prolonged cooking of meat or vegetables, especially greens. 3  Also called pot liquor. 4  An aqueous solution of a nonvolatile substance. 5  A solution, emulsion, or suspension for industrial use.
From this practice, distillation of liquors came about. This is where the difference between alcohol and liquor becomes clear. Liquors, also called âspirits,â concentrate the alcohol in fermented fruits and grains through distillation. This is the reason why not all alcoholic beverages are classified as liquor.Beer, for example, is an alcoholic drink but is not liquor, per se, as it is produced through undistilled fermentation.thanol is the form of alcohol that is found in alcoholic drinks. This last category is where alcohol and liquor intersect. Drinking alcoholic beverages can be traced as far back as 10,000 BC or earlier. There are empirical evidences that men used vessels to ferment drinks from fruits.
