Waste water treatment by Aeration

According to my experience in some #wastewater water units, I want draw your attention to the most important and remarkable part of #effluenttreatment in the name of #aeration . Wastewater aeration is critical to biological treatment systems. These include aerobic activated sludge systems, Sequencing Batch Reactors (SBR), nitrification-denitrification in a single basin, and Membrane Bioreactors (MBR). Treatment plants inject pressurized air into a liquor of sludge and wastewater. Promoting the growth of #microorganisms that consume organic matter and supply the air for diffused aeration systems. Unlike chemical treatment which uses chemicals to react and stabilize contaminants in the wastewater stream, biological treatment uses microorganisms which occur naturally in wastewater to degrade wastewater contaminants. Most municipal and industrial water treatment plants use aeration as part of an overall process to purify the water and rid it of its #pollutants . Aeration is a simple tool and speeds up the natural elements towards keeping a healthy ecosystem balance. When the balance is offset, the evidence is seen in sludge-filled waterways, algae-laden lakes and rivers, and polluted oceans. In very serious instances of failed water treatment, contaminated waterways contribute to illness even death in all species connected to the water source – humans included. There are three main types of aerators used in waste treatment facilities: a. Packed Tower Aerator, b. #diffused bubble Aerator and c. Spray Aerator. All types can be effective in order to decrease pollutants which can see the impacts of them on all significant parameters such as BOD5, COD, SVI, dissolve O2, MLSS and F/M. Consequently, consider to this equipment can lead to higher efficiency (some times more than 50%) of treatment which is surprising!!! #oilandgas #chemicalengineering #processengineering #refinery
