ARMY FILTRATION OF LIQUIDS
|Publication Date:||17 December 2003|
This UFC addresses various solid-liquid filtration systems, their associated filtration media, the use of various filtration process technologies, equipment and component specifications and design, available manufacturers and equipment sources, advantages and disadvantages of different filtration systems, solids disposal, costs, operational requirements (O&M), and safety considerations. The described equipment can be installed alone or at various stages in an overall treatment process, depending on application-specific
Applications will generally be at a flow rate of less than 15 L/s (240 gpm) with suspended solids concentrations of less than 1000 ppm. Filtration technologies include granular media (sand) filtration systems, ranging from pressure filtration vessels to gravity filtration systems to continuous backwash systems, as well as systems using filter fabrics such as bag and cartridge filters. The use of precoats and filter aids are included as applicable.
DG 1110-1-2 covers adsorption systems, which are not included herein and which may be called filters.
This document provides practical guidance for the design of filtration systems to remove suspended solids from liquids. Liquid in this document means water.
This UFC applies to all Service elements and all Contractors having responsibility for designs that include liquid filtration processes.
