TEST.METHOD <br /> w <br /> A. PURPOSE <br /> The purpose_of_this,test-method._is_to_verify_that-a_-plant-complies-with-the-applicable-class <br /> - - - effluent requirements during a six-month period. <br /> Performance evaluation of the plant shall be independent of design and construction. However, <br /> structural weaknesses or defects and failures of process support equipment, shall be reported in <br /> the test results. <br /> B. PREQUALIHCATIONS <br /> 1. APPLICATION: The application for performance evaluation of a particular model or <br /> model series shall.include a basic description, design data, drawings, and parts and <br /> materials specifications for the plant and all equipment and appurtenances. A complete <br /> installation, 'operation, and maintenance manual, including a thorough discussion of <br /> process fundamentals. shall accompany the application. <br /> 2 MODEL SERIES: For a series of plants of the same model, varying in rated treatment <br /> capacities between 1514 and 5678 L (400 and 1500 gallons) per day, results achieved <br /> by the smallest plant in the series shall be indicative of the capabilities of all other plants <br /> in the series. The design and configurations of larger capacity plants shall be <br /> proportionally identical to the plant tested.' ; <br /> C. TESTING SEASON ; <br /> The test can be carried out at any time of the year. If the test is conducted during cold weather, <br /> the plant and equipment shall be protected from freezing. If the test is conducted during warm <br /> weather, the temperature of the aeration compartment contents shall not exceed 30°C (86M. <br /> D. ANALYTICAL METHODS <br /> All sample collection and analytical methods shall be those in the sevens edition of Standard <br /> Methods for the Examination of Water and Wastewater published by the American Public Health <br /> Assodation1, except as otherwise specified. i <br /> . i <br /> `When defining "proportionally identical;' some of the parameters that should be considered are <br /> hydraulics, dimensions. mixing, and filtration. <br /> 2Americm Public Health Association, 1015 Frfteenth St., N.W., Washington, DC 7.0005. <br /> B_1 <br /> - ��... ..� .....::�.�:'_-_.1'T--.�,_:��'���'f,E u�_v.._ .. »M`�1':,h"_ ,.; .. .�..¢L'P 3a s5`.ktr^- ., :;F'.ta �" ..
