1.0 INTRODUCTION

This Manual is a product of the Phase II MWRA/MASCO Mercury Work Group, End-of-Pipe Subcommittee, Pretreatment Guidance Subgroup. It should be used as a reference by industrial facilities owners in the development of an action plan to solve a sewer discharge compliance problem. The plan of action may involve initiation of a source reduction program or enhancement of an existing one, and it may also involve implementation of an industrial wastewater pretreatment strategy. This Manual is intended to help facilities to understand the various steps that may be entailed in a comprehensive source reduction program and in the selection, design, installation, and operation of an industrial wastewater pretreatment system.

The wastewater pretreatment discussions in this Manual are directed toward all types of pretreatment systems and are then focused on additional considerations specific to pretreatment systems that include mercury removal processes. Therefore, this Manual may be especially valuable to facilities in the health care industry. The following topics are discussed:

Pretreatment Background
Steps to Achieve Discharge Compliance
Selecting a Consultant
Source Reduction Concepts
Wastewater Characterization
Coordinating Source Reduction, Segregation, and Pretreatment
Pretreatment System Economic Analysis
Types of Pretreatment Systems
Pretreatment System Bench-Scale Testing
Pretreatment System Pilot Testing
Pretreatment System Implementation and Operation
Permitting and Licensing Issues

The Pretreatment Guidance Subgroup hopes that this Manual will be a valuable and practical tool for many facilities, providing insight into the many variables associated with the selection, design, installation, and operation of industrial wastewater pretreatment systems, including those incorporating mercury removal technologies.
