Biological Wastewater Treatment to Offer a Helping Hand toward a Cleaner Environment

Abstract: The use of biological functions to process wastewater has nowadays been a popular trend. The growing health problems owing to the contamination of water bodies has triggered an urgent need to develop treatments to treat wastewater. A biological wastewater treatment is a technique that mainly makes use of bacteria, protozoa, and possibly other specialty microbes to treat wastewater. A considerable surge in the industrial development has resulted in an upsurge in the release of wastewater into the environment, which has boosted the demand for biological wastewater treatments.

About three-fourth of the wastewater from all over the globe is released back into the environment without any processing, thus polluting freshwater bodies. The water pollution, which has been a globe problem since ages, has now started imperiling the people’s health on a major scale. The growing health problems owing to the contamination of water bodies has triggered an urgent need to develop effective treatments to treat wastewater. The use of biological functions to process wastewater has nowadays been a popular trend. The biological wastewater treatments help in eradicating all possible suspended solids before the residual water, called effluent, is dumped back into the nature. Biological wastewater treatment is the most viable, affordable, and easy to process technique which works wonderfully on wastewater that has massive amounts of dissolved organic matter. 

A report by Research Dive reveals that the global biological wastewater treatment market is expected to observe significant growth with a CAGR of 5.4% in the 2019-2026 timeframe. Among various regions across the globe, the North America region is expected to be at the forefront in the race for wastewater treatment, as there are many leading industries in this region that harness this wastewater treatment technology. The North America biological wastewater treatment market is foreseen to hold a leading share, growing with a CAGR of 4.6% from 2019 to 2026.

What is a Biological Wastewater Treatment System?

A biological wastewater treatment is a technique that chiefly makes use of bacteria, protozoa, and possibly other specialty microbes to treat wastewater. These microorganisms breakdown organic impurities present in the wastewater for their own food. This generates a flocculation effect, thus enabling the organic matter to filter out of the solution.

The biological wastewater treatment is usually divided into three types, as follows:

  1. Aerobic: In this, the microorganisms need oxygen to breakdown organic substance to microbial biomass and carbon dioxide.
  2. Anaerobic: In this, the microorganisms do not need oxygen to breakdown organic substance and usually form carbon dioxide, methane, and additional biomass.
  3. Anoxic: In this, the microorganisms make use of other molecules than oxygen for their development, such as for the elimination of selenate, nitrate, nitrite, sulfate, and selenite

How does a Biological Wastewater Treatment System Function?

A biological wastewater treatment system can include various different procedures and various types of microorganisms. These systems also include some unique type of operational processes that differ based on the situation required to keep the growth of the levels of biomass at an optimal stage for particular microorganisms. For instance, a monitor is often needed to adjust the aeration for maintaining a constant dissolved oxygen level to uphold the system’s bacterial multiplication at an appropriate level and to fulfill discharge requirements.

Apart from maintaining the dissolved oxygen levels, biological systems usually require to be balanced for nutrients, load, flow, pH, and temperature. Maintaining the combination of biological wastewater treatment system factors makes the treatment process highly complex.

What is Boosting the Popularity of Biological Wastewater Treatments?

Biological wastewater treatments are based on the ability of a set of microorganisms to degrade the organic material present in the wastewater. Biological wastewater treatments enhance the natural process of microbial degradation to breakdown industrial wastewater contaminants. This helps in filtering out contaminants and other undesirable substances from the wastewater.

The aim of a biological wastewater treatment is to generate a system in which the outcomes of decomposition can be effortlessly collected for appropriate disposal. As biological wastewater treatments are effective and more reasonable than various other mechanical and chemical methods, they are extensively used across the globe in many industrial sectors.

A considerable surge in the industrial development has resulted in an upsurge in the release of wastewater into the environment, which has boosted the demand for biological wastewater treatments. Many biological wastewater treatment service providers are introducing novel techniques and teaming up with foremost companies to deal with wastewater issues.

Recent Advances in the Biological Wastewater Treatment Arena

Nowadays, there is a serious need for optimal biological wastewater treatment solutions for every industry that discharges huge quantities of wastewater. As a result, various industrial organizations are looking for effective as well as affordable wastewater treatment solutions. However, every industry needs different type of biological wastewater treatment for every single project depending on the type of wastewater it releases. Biological wastewater treatment developers and providers are introducing novel techniques by massively investing in research and development projects that can resolve the wastewater problems and safeguard the life on earth. For instance,

  • Investigators from the University of Hong Kong (HKU) have introduced a novel wastewater treatment technique to effectively eliminate health hazardous chemical contaminants from wastewater.
  • Clariant, a global frontrunner in the development, manufacture, application, and supply of specialty chemicals and services to the gas and oil industry, introduced a wastewater treatment plant at the zero liquid discharge site, Bonthapally in India. The plant is estimated to treat 300 kiloliters of wastewater each day.
  • DAS Environmental Expert, a foremost environmental technology firm that delivers sustainable solutions for the treatment of waste gas and wastewater, has launched novel systems—ranging from a single biological purification system to entire treatment plant or engineering facility equipped with wastewater technology—to acclimatize with the needs of every single customer.
  • Evoqua Water Technologies, a leader in helping governments and industries to safeguard and improve water resources across the world, developed a wide array of optimal biological wastewater treatment processes and systems for protecting water resources. 
  • Irrespective of the COVID-19 disaster, Lifequest’s (LQWC) subsidiary named Biopipe Global, with its advanced sludge and chemical-free sewage treatment technology, has shifted one plant to the U.S. from Turkey. 

The Future Scope of Biological Wastewater Treatment Market

The outbreak of the COVID-19 pandemic in 2020 has significantly surged the demand as well as importance of biological wastewater treatments. This is mainly due to the growing awareness to process wastewater to avoid the spread of diseases during the turmoil created amidst the pandemic. A considerable surge in industrial development and government initiatives for safeguarding water bodies is estimated to propel the growth of the biological wastewater treatment market in the upcoming years.
