Million tons of sewage is discharged into bodies of water and approximately two million children under 5 years of age die due to waterborne illnesses.
Almost 3/4 (71%) of the Earth is water.
Only 3% of the world’s water is suitable for the human use. About 2% of that amount found in ice caps and glaciers. Further, millions tons of sewage is discharged into water bodies and near about two million children under 5 years of age die due to waterborne illnesses. The situation has reached an alarming level. As a consequence, wastewater treatment plant design projects have become an utmost priority in every country.
Wastewater Treatment System
Due to the scarcity of usable water, the requirement of the wastewater treatment system is essential. This is a kind of technology that receives, stores, treats and disposes waste water from residences (washing machines, sinks, baths, other domestic water), and municipality.
A wastewater treatment plant is a state of the art mechanism, which includes a septic tank, pipes, percolation areas, drains and fittings this makes sure that the water is treated and discharged correctly.
Here are some of the tanks used in wastewater treatment plant you can find online.
- Biosolids Storage Tanks
- Aeration Tanks
- Industrial Holding Tanks
- Equalization Tanks
- Membrane Bioreactor Tanks
- Sequencing Batch Reactor Tanks
- Benefits of the Plant
Three are a whole lot of benefits of wastewater treatment plant projects. Read on to know them.
The wastewater that comes from household, hospitals, commercial establishments, sewage and institutions, municipality is impure and not usable. The water is no longer beneficial or is no longer suitable for use. This is because the wastewater contains chemicals, bacteria, and other toxins. The water treatment plant is designed to decrease the pollutants to acceptable levels and make the water usable and safe to discharge back into the environment.
There are two types of wastewater treatment plants.
1. Chemical or physical treatment plant – This treatment plant uses chemical reactions and physical processes for treating the wastewater. These plants are mostly used for treating wastewater that comes from factories, industries, and manufacturing units. This is because most of the wastewater coming out of these industries comprises of chemicals and other toxins that are largely harmful the environment.
2. Biological wastewater treatment plant – As the name suggests, biological waste treatment plants are designed to use biological matter and bacteria to break down waste matter. These plants are ideal for treating wastewater from business premises and households.
Wastewater Treatment Process
The process of treating wastewater includes the following:
- Wastewater collection – The wastewater is collected and directed to a central point using wastewater collection systems.
- Odor Control – All odor sources are treated by neutralizing the foul smell producing elements. This is done using some chemicals.
- Removal of Objects – Large objects like cotton buds, nappies, plastics, rags, sanitary items, diapers, broken bottles , etc. are removed.
- Treatment – Macrobiotic solid matters are separated from the wastewater.
- Tertiary treatment – There are many other steps before. However, at this stage, up to 99% of the impurities are from the wastewater.
- Disinfection – This process guards the health of animals and people’s who use the water for other purposes.
- Sludge Treatment – The sludge, produced and collected during the treatment processes, is treated and sent back to the environment. This can be used for agricultural use.
Wastewater treatment plant is an innovative way to treat wastewater and make it usable.
