Aeration Treatment To Remove Sulphur Gas

Purpose of Aeration ~ Wine Aerator, Garden Aerator, Pond Aerator ...

Iron Removal For domestic drinking water, iron is not an acceptable constituent. It imparts a bitter, metallic taste and stain wash basins, toilets, urinals, bath tubs, showers, tiled floors and walls, cloths, in fact, everything it comes in contact with. Iron concentration exceeding 0.2 to 0.3 mg/l may be objectionable even though its presence is not objectionable from the hygienic point of view. Aeration is also used for oxidation of iron in the water into compounds which are subsequently removed by filtration. Iron filtration operate on the principal of oxidizing the iron to convert it from a ferrous (dissolved or soluble) state to a ferric or undissolved state. Once in the ferric state, the insoluble iron compounds can be filtered out. For best results, the pH of the water should be between 6.5 and 10.0. The higher the pH, the faster the dissolved ferrous state can be converted to the insoluble ferric state. Reduce Algae Aeration removes nitrogen, ammonia and soluble phosphate which are food for algae. The deprivation of food reduces algae growth. Aeration also helps aerobic bacteria, which have a very robost appetite for organic matters, to thrive. Aerobic bacteria are more efficient consumer of nutrients and thus their consumption by the aerobic bacteria lead to food starvation by the algae.
