This EWRI/ASCE Standard guideline provides several techniques and guidance for use in developing quality assurance requirements for specifying fine-pore aeration equipment. Three methods for specifying compliance testing are described, including information on appropriate applications, advantages and disadvantages of each method, and the procedures to be followed. Two methods are based on conducting oxygen transfer shop tests, and the third is based on conducting full-scale oxygen transfer testing. The basis for compliance testing includes oxygen transfer testing of selected individual diffusers or two reference tests-dynamic wet pressure and effective flux ratio. A description of test procedures and diffuser sampling is included. Quality assurance benefits all parties involved in the manufacturing, specification, and use of aeration equipment by providing quality diffusers delivered at the site at a reasonable cost.
