Filter Maintenance And Operations Guidance Manual

This manual was developed to provide guidance on techniques and procedures for maintanance and operation of water filtration plants and to provide background information and advice on where to find additional information.

The report of multi-disciplinary team of engineers and practitioners from a research project commissioned by the Association to create a resource to help water utilities operate and maintain water distributions systems to prevent water quality from deteriorating. They look at prevention programs, qu

Water operators will find a wealth of hands-on information on the operation and maintenance of pretreatment, rapid-rate granular media filtration, slow-sand filtration, and diatomaceous-earth filtration systems in this book. This practical guide provides recommended procedures for operating, monitoring, and maintaining all types of filters used for conventional water treatment. These procedures are tested and time-proven by hundreds of water utilities and filtration experts to provide high filter efficiency, excellent water quality, long filter runs and minimum downtime. The book also gives advice on what not to do-and why-so you can avoid water quality problems, filter damage, and treatment problems in the future.

This manual suggests design operating and performance criteria for specific surface water quality conditions to provide the optimum protection from microbiological contaminants.

In conventional treatment plants, granular media filtration is the most important unit process for maintaining high quality drinking water. Filter condition surveillance is important for tracking the condition of filters. The objectives of this report are to identify, select, evaluate, and provide guidance on condition assessment methods that are less interruptive to normal filter operations than those currently used in the water industry. Methods that are less interruptive can be applied more frequently and require fewer resources. These methods will help utilities to determine the condition of their filters on a more regular basis and assist in achieving optimal filter performance.
