Industrial Waste Treatment Process Engineering includes design principles applicable to municipal systems with significant industrial influents. The information presented in these volumes is basic to conventional treatment procedures, while allowing evaluation and implementation of specialized and emerging treatment technologies.
What makes Industrial Waste Treatment Process Engineering unique is the level of process engineering detail. The facility evaluation section includes a step-by-step review of each major and support manufacturing operation, identifying probable contaminant discharges, practical prevention measures, and point source control procedures. This theoretical plant review is followed by procedures to conduct a site specific pollution control program. The unit operation chapters contain all the details needed to complete a treatment process design.
Pollution Prevention Evaluation
Chapter 1-1 provides process evaluation guidelines to review individual manufacturing operations, identify probable pollution generation sources, and investigate possible corrective measures. Examining this model allows exploring corrective action for raw materials selection, materials storage, feed preparation, manufacturing, product recovery, purification, finishing, packaging, solvent recovery, and support facilities, and suggests data and procedures appropriate for developing site-specific plans to implement pollution prevention, source correction, and waste minimization measures at actual facilities. Study results provide the basis for a complete facility waste management program.
Preliminary Central Treatment Evaluation
The guidelines profile an overall waste facility control plan that incorporates waste management practices, segregated treatment systems, central treatment systems and effluent recycling. Central treatment facility development includes sewer segregation, selecting individual and central treatment technologies, equalization and pretreatment. Chapter 1-2 also includes discussion of procedures to verify selected treatment technologies and develop design criteria.
Waste Treatment System Process Design
Chapter 1-3 develops the resultant data into required waste treatment systems, treating the resulting sewer discharges, segregated waste streams, or both. Process development includes selecting ancillary facilities such as waste storage, chemical storage and feed, spill and emergency discharges, sludge treatment and air emission management, and exploring the limitations imposed by the site's location and physical characteristics.
Chapter 1-4 discusses modulating highly variant industrial waste characteristics to acceptable downstream treatment limits, and relates influent effects on effluent variability and inherent process control to Statistical Quality Control (SQC) principles.
Chapter 1-5 discusses guidelines for evaluating chemical processes for industrial waste treatment, emphasizing basic chemistry and specific criteria governing effectiveness. The chapter includes equalization, reactor configuration, mixing, and sludge management in developing the treatment train, and chemical reagents, feed systems and controls.
Chapter 1-6 examines chemical precipitation as a treatment method to remove dissolved waste components, and examines the elements of a precipitation system.
This chapter covers the application of oxidation and reduction chemistry to destroy dissolved waste components or to condition them to enhance their removal by chemical precipitation.
Neutralization and pH Control
Chapter 1-8 discusses adjusting wastewater alkalinity or acidity as pretreatment or as a sole treatment method to promote precipitation. It explains in detail how wide and rapid wastewater alkalinity variations affect reactor configuration and selected instrumentation.
This chapter reviews removing colloidal or emulsified waste constituents by destabilization or demulsification and coagulation and separation, employing flotation or gravity separation.
Chapter 1-10 covers separating coagulated or emulsified floating materials by contacting the resulting floc with air to increase the buoyancy rate, enhancing low-density floc separation.
