Membrane filtration means a pressure or vacuum driven separation process in which particulate matter larger than one micrometer is rejected by an engineered barrier, primarily through a size exclusion mechanism, and which has a measurable removal efficiency of a target organism that can be verified through the application of a direct integrity test. This definition includes the common membrane technologies of microfiltration, ultrafiltration, nanofiltration, and reverse osmosis.
Assembly means an item forming a portion of a system or subsystem that—
Backflow Prevention Assembly means any mechanical assembly installed at a water service line or at a plumbing fixture to prevent a backflow contamination event, provided that the mechanical assembly is appropriate for the identified contaminant at the cross connection and is an in-line field-testable assembly.

Substance use disorder professional means a person
Commencement Date of the Contract means the date of signing of the Contract between the Purchaser and the Contractor.
Diatomaceous earth filtration means a process resulting in substantial particulate removal in which a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and while the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake.
Air contaminant source means any and all sources of emission of air contaminants whether privately or publicly owned or operated (Section 19-2-102(2)).
Disinfection means a process which inactivates pathogenic organisms in water by chemical oxidants or equivalent agents.
