Chemicals Used in Water Treatment


Alkaline chemicals, such as sodium hydroxide (NaOH) and calcium hydroxide (Ca(OH)₂), are frequently used to adjust the pH levels of wastewater. Many biological processes in STP require a specific pH range for optimal activity. For example, certain bacteria used in activated sludge processes thrive at a pH of around 6.5 to 8.5. By adding alkaline substances, the pH can be increased, creating a favorable environment for microbial action that breaks down organic matter.


Pyrroloquinoline quinone (PQQ) is a compound that has been gaining attention in recent years for its potential health benefits. Originally discovered as a cofactor for bacterial enzymes, research has broadened our understanding of PQQ, revealing its promising roles in human health, particularly concerning cellular energy production, neuroprotection, and overall well-being.

Water is an indispensable resource for various industrial processes, ranging from manufacturing and thermal power generation to food processing and pharmaceuticals. However, the quality of water utilized in these operations is crucial for optimal performance and compliance with environmental regulations. This is where industrial water treatment chemicals play a vital role. In this article, we will explore the various categories of chemicals used in water treatment, their functions, and their importance in maintaining water quality across industrial sectors.


In conclusion, the use of chemicals in Sewage Treatment Plants is fundamental to achieving effective wastewater treatment and ensuring the protection of both public health and the environment. By understanding their roles and implementing effective management strategies, STPs can enhance their operational efficiency while minimizing risks associated with chemical usage. As technology and regulations evolve, there is a growing imperative for continuous improvement in chemical use practices, paving the way for more sustainable and effective wastewater management solutions.
