With rising population, urbanization and industrialization combined with closing river basins, India is left with highly water stressed regions with the inability to efficiently manage its water resources. Consequently, the average per capita freshwater availability is expected to reduce to 1241 m3 by 2025. It is also estimated that around 29.3 billion cubic meters of water will be required for domestic and industrial purposes by the year 2025. Therefore, efficient and economic biological treatment of industrial wastewater and its reuse have emerged as a potential solution to meet water demands in the future.

Fats, Oils and Grease, popularly known by its acronym FOG, has been a growing concern worldwide. It affects the performance of wastewater treatment plants and industrial treatment units. According to reports, 47% of sanitary sewer overflows occur due to FOG related issues in the US. Similarly, more than 50% of sewer blockages happen in the […]

Wastewater management is one of the major global challenges faced by developed as well as developing countries today. Rapid industrialization has led to extensive industrial wastewater generation which is one of the leading causes of water pollution. Also, stringent treatment regulations are now in place for sewage and industrial effluent being released in the environment. Thus, an effective industrial wastewater treatment strategy is important.

Biological wastewater treatment, also known as secondary wastewater treatment, is one of the key components of any effluent treatment plant. In this process, the microbial population acts on the sewage or industrial effluent and helps in the degradation of harmful substances and pollutants. The main aim is to protect the environment and public health from the negative effects of untreated or substandard effluent. Given the importance of this process, a comprehensive understanding and regular evaluation and monitoring are critical to keeping maintain the efficiency of the biological system.

Technological advancement in recent times has enabled the wastewater treatment industry to develop new approaches focused on improving pollutants and nutrient removal methods, better efficiency and lower costs. Aerobic granular sludge technology is fast emerging as one of the promising and innovative methods to achieve wastewater treatment objectives.

Water contamination is one of the major challenges worldwide. Several factors such as rapid urbanization, industrialization, population explosion and changing lifestyle habits have contributed to the pollution of water bodies and health problems to humans. In this context, wastewater treatment is of great importance to prevent water contamination and protect the environment.

Wastewater treatment plants are used across the world to treat the extensive amount of wastewater generated every day. The main aim is to protect the public from health hazards caused due to untreated wastewater. Moreover, wastewater treatment is essential to prevent environmental pollution. Biological wastewater treatment is the most important process at any treatment facility where living microorganisms play a vital role in degrading organic waste. Among the various components of the system, MLSS is an operational control parameter that needs to be optimized for best treatment results.

The petrochemical industry is one of the fastest growing industries which contributes significantly to the growth of world economies. However, different refinery activities such as equipment cooling and desalting which involves water results in the generation of effluents. Also, an extensive amount of hazardous waste consisting of organic and inorganic compounds are left behind, which needs treatment.
