Document Summary

The principal objective of a wastewater (or water) treatment facility is to provide a product that satisfies a set of quality standards at a reasonable price to the consumer. The undesirable constituents must be removed and/or rendered innocuous by appropriate biological, physical or chemical changes in the wastewater (or water). engineering and design. impact on the cost. Two pieces of information are critical to process analysis. Although process design represents a small part of the cost (5-20%), it can have a major. The creation and assessment of alternatives to meet the objective is called process extent of the change how fast does the change occur. The first will establish if a process is satisfactory to conduct a task. The second will dictate how large a basin is required so that the liquid has sufficient time to undergo the necessary change.
