Project Specifics
A pharmaceutical client’s industrial wastewater pre-treatment system was not meeting discharge limits for pH. Geosyntec provided technical support for a Pre-Hearing Brief relating to a Notice of Violation for pH exceedances. Key causes of pH exceedances were identified, including lack of flow equalization and inadequate design of the pH treatment system.
Geosyntec Scope of Services
Geosyntec developed and implemented a sampling plan to evaluate wastewater characteristics. Issues included high five-day biochemical oxygen demand (BOD5), total suspended solids (TSS), ammonia (NH3), and total Kjeldahl nitrogen (TKN) concentrations. Geosyntec reviewed chemical, physical, and biological pre-treatment options, and designed a chemical and physical treatment system to adjust the pH and TSS.
Notable Accomplishments
Geosyntec worked with the regulators to raise the wastewater discharge limits for BOD5, TSS and ammonia to avoid expensive biological treatment system or surcharge fees. The new pre-treatment system consisted of a new equalization basin, a two-stage pH control system and bag-filtration.
