1.1 This practice covers the procedure used to perform pressure in-line coagulation-flocculation-filtration of water and waste water. It is applicable to water and waste water with relatively low suspended solids (<30 mg/L). The waste water practice is applicable for any size filter greater than 100 mm (4 in.) in diameter.

1.2 This practice can be used to determine the effectiveness of flocculants or coagulants, or both, and filter medium(a) in removing suspended and colloidal material from water and waste water.

1.3 Interval between filter backwashing, backwash requirements, rinse requirements, and effect of filtration rate on effluent quality can also be obtained with this practice.

1.4 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
