Boiler Wastewater Treatment & Storage

CONSTRAINTS

This project is limited by several factors that could impact the effectiveness of the pretreatment option and wastewater storage alternatives. The exact chemical make-up of each compound added to the influent boiler water are unknown with respect to their volumes, ratios, concentrations, and frequency. This will remain unknown because the manufacturer has established this as their trademark recipe for boiler maintenance. Additionally, the members of the GCRP team are unauthorized to retrieve a sample of the boiler wastewater due to constraints of occupational safety and health regulations. Because of this, collection methods of the sample may not consistent with proper sampling and storage methods outlined in the proposal.

The client has also requested that the water is able to be conserved or reused on site if possible and that no permitting is required in the managemnt solution.

Influent wastewater must meet be treated to certain standards per the WWWTP. The current state of GCR’s wastewater does meet the standards of the WWWTP and therefore must be pre-treated to allow disposal.
