sanitary survey
A detailed evaluation or inspection of a source of water supply and all conveyances, storage, treatment, and distribution facilities to ensure protection of the water supply from all pollution sources.
evaporation
The process by which water or other liquid becomes a gas (i.e., water vapor or ammonia vapor).
total suspended solids (TSS)
See suspended solids.
cross-flow filtration
A type of membrane filtration where the water being filtered flows across the surface of the membrane parallel to the membrane modules.This keeps particle buildup and fouling to a minimum. The flow that is not filtered (retentate) becomes concentrated and flows out the end of the membrane fiber as a wastestream that is returned to the reactor. Systems using cross-flow filtration have a constant flow of retentate recycled back to the reactor. Also see dead-end filtration.
positive pressure
A pressure greater than atmospheric pressure, measured as pounds per square inch (psi), inches of water column, kilograms per square meter or centimeter (kg/m2 or kg/cm2), or Pascals (Pa).
