White Paper: The Role Of Alkalinity In Aerobic Wastewater Treatment Plants: Magnesium Hydroxide vs. Caustic Soda

Modern day wastewater treatment plants must use a variety of physical, chemical and biological processes to meet effluent treatment guidelines. During the course of treatment these plants consume a variety of different chemicals. In some treatment plants an alkali is used to provide the alkalinity required to maintain effective biological activity and for pH control. This paper will discuss the role that alkalis play in wastewater treatment.
