Dynamic Optimal Groundwater Remediation by Granular Activated Carbon

by Teresa B. Culver, (A.M.ASCE),

Document Type: Proceeding Paper

Part of: North American Water and Environment Congress & Destructive Water

Abstract:

Objective functions to describe the operating and capital costs of GAC treatment are incorporated into a control theory model for optimal pump-and-treat groundwater remediation design. The control theory model, including shifts in the Hessian matrix, could not reliable handle the non-convex functions. Linearized iterative approximations of operating costs and multiple capacity constraints were used to solve the problem, while maintaining convexity. Dynamic policies were found to be superior to steady-state policies even when capital costs of treatment were included.
