Biologic wastewater treatment methods utilize heterotrophic bacteria to consume wastewater organics generated in industrial processes. Optimally, a final effluent water is produced that is low in organics and solids and that is suitable for land applications and municipal discharge.
THE ROLE OF PH
Bacteria employed in biological wastewater treatment processes cannot tolerate pH extremes, performing best in the 6.0 to 8.0 range. Maintaining the proper pH is a concern for operators since wastewater pH values typically fluctuate throughout the year. In fact, profiles of wastewater show that variations in the pH scale from 3.5 to 10.0 are common, unacceptable parameters for supporting bacterial growth.
TARGETED SOLUTIONS
Heritage Systems has developed pH adjustment strategies effective in conditioning wastewater and in improving the performance of treatment systems while minimizing the impact on the environment.
Our choice of chemistries to be applied will depend on the specific treatment process to be targeted. Available pH adjustment chemistries include potassium hydroxide, sodium hydroxide, magnesium hydroxide, aqueous ammonia, sulfuric acid and hydrochloric acid.
In addition, we provide simple solutions for those processors that must adjust the pH of their wastewater before releasing it into municipal treatment systems.
