There are sewage treatment plants everywhere in the world now, and the number of these plants increases day-by-day. People often wonder about the necessity of wastewater treatment and recycling products. As years pass by, humans continue to disrupt the environmental balance which paves the way to serious damages such as climate change. We act without realizing the troubles that are to follow.
Water scarcity is not a new thing for us; many countries around the globe have been facing this issue for a while now. We don’t realise the value of something until it’s completely lost, such is the case with water. Waste water treatment and sewage water treatment was an eye opener, but people still wonder how effective they are and whether it is safe to use it again. Well, it’s always better to use it in one way or another than wasting it completely to a state where it cannot be reciprocated. There are numerous ways, in which sewage water treatment can be done; to begin with the aeration process.
Aeration process:
“The process of letting air into the wastewater in order to allow aerobic biodegradation of the organic materials” is aeration. It is usually the first process done in a treatment plant. This process lets air and water to be in close contact which helps in removing the dissolved gases such as carbon dioxide and also oxidizes dissolved metals like iron, hydrogen sulphide, and other volatile organic chemicals (VOCs).
Membrane Bioreactor (MBR):
The membrane bioreactor technology helps in performing the critical solid-liquid separation function. The process makes use of membrane filtration equipment such as low-pressure microfiltration (MF) and ultrafiltration (UF) membranes with a biological treatment method. The vacuum (gravity-driven) and pressure-driven systems are the two types used in MBR.
Moving Bed Bioreactor (MBBR):
The process of moving bed bioreactor attains good results of disposal with low energy consumption. It is used to remove organic substances, nitrification and denitrification. The MBBR system has an activated sludge aeration system where the sludge is collected in a recycled plastic carrier. The carriers have large internal space for an optimal contact with water, air and bacteria.
The bacteria grow in the surface of the carriers and breaks down the organic matter from the wastewater. The aeration system helps in keeping the bacteria active in the carriers.
Sequential Batch Reactor (SBR):
The basic process of an SBR is by bubbling oxygen into the wastewater to reduce the biological oxygen demand (BOD) and the chemical oxygen demand (COD). The reduction of BOD and COD makes it suitable to use on land. The SBR process is divided into five periods: Fill, React, Settle, Draw, and Idle. The fill and react periods may differ according to the aeration and mixing procedures. The SBR has several configurations but the basic process remains the same.
Submerged Aerated Fixed Film (SAFF):
This is a cost-effective method that is mainly used in residential and commercial complexes. The SAFF technology has three stages, primary, secondary treatment and final settlement/clarification. The SAFF process reduces the biological oxygen demand (BOD) and also the suspended solids (SS) which is powerful enough to contaminate river and seawater. The process improves the “effluent discharge quality”.
Having mentioned some of the types of sewage treatment methods, it is clear that these treatments are indeed effective and will make the water reusable. It may not be suitable for drinking but can be definitely used for other purposes. Wastewater treatment is no more a luxury but a necessity. It will soon become mandatory as we move forward to live in this world.
