Clarification is the final step in wastewater treatment. Once the water has been thoroughly cleansed, clarifiers remove both any remaining pollutants and the chemicals added by the treatment process (such as chlorine), so water can be safely released back into the local environment.

THE COMPLETE GUIDE TO WASTEWATER CLARIFICATION
Written by some of the world’s most knowledgeable authorities on wastewater clarification, Clarifier Design helps readers make fully informed decisions about this essential step in the wastewater cleansing process.
Contrasting traditional methods with the many leading-edge choices in clarifier design approaches, the text establishes criteria and protocols for decision-making. For potential buyers evaluating clarifier effectiveness for their particular situations, for vendors wanting to demonstrate the superiority of their designs, for designers creating new variations or products, for anyone who needs to compare the many types and configurations of clarifiers that are available and in use — there is no better choice that than this manual from the Water Environment Federation.
Clarifier Design is the most complete and useful treatise available on wastewater clarification. Its demystifying explanations will help everyone approach the process and its technologies with more understanding, confidence — and clarity.
