72 Wastewater reclamation and reuse in a petrochmical plant

摘要

A large petrochemical plant located in a water-limited areea is a major water user. The plant is facing a critical water problem because of several factors: (1) the raw water total dissolved solids (TDS) content has been increasing, (2) water rationing, which limits plant production, occurs during drought periods, (3) the plant planning for a major expansion that requires major additional water supply, and (4) there is persistent community pressure for wastewater discharge reduction. A water resource management and planning study was conducted for this plant to besolve the water problem. This chapter describes the results of the study and the design of a pilot plant program for the testing of a wastewater treatement and recycling system.
