   What is a double wall separation in surface water treatment?

   • In surface water treatment applications, engineers should design double-wall separation (an air space) between unfiltered water (flocculation and sedimentation basins) and filtered water (underdrains and clearwell). This will allow operators to check for fractures in either wall (the air space will fill with water).

   How do design engineers evaluate water quality in a disinfection system?

   • Design engineers must evaluate source water quality in the design of any primary or secondary disinfection system (WAC 246-290-110). Some water quality parameters, such as iron, manganese, natural organic matter, dissolved organic carbon (DOC), ammonia, and sulfide exert a chlorine demand.

   Does a water treatment plant need a component cost assessment?

   • However, lack of published data may make detailed component cost assessments necessary to evaluate alternative treatment methods for small water systems. Water treatment plant designs must comply with state or locally adopted building, mechanical, electrical, and land use codes (WAC 246-290-200(b)).

   Do I need a CT6 disinfection for open seawater sources?

   • Open seawater sources must be treated to a minimum CT6 prior to the first connection. (WAC 246-290-451(4)). This level of primary disinfection provides an additional barrier in case the integrity of a membrane or another water system component is compromised.

   How do engineers determine a water treatment system?

   • Engineers need to consider the amount of water the treatment process requires to backwash, regenerate, rinse, and/or filter to waste when determining the maximum daily treatment capacity and raw water supply requirements. Water systems must use the highest quality sources feasible (WAC 246-290-130(1)).

   What is the design approach to disinfection treatment?

   • The design approach to disinfection treatment will differ depending on the intended purpose of the application. In some cases, engineers use primary disinfection, which addresses microbial risk in the source water. In other cases, engineers use secondary disinfection, which addresses microbial risks in the distribution system.
