A device used to increase the pressure of a gas or vapour generally driven by a high pressure source of the vapour to be compressed. Typically an ejector that uses high-pressure steam to increase the pressure of a lower pressure steam.

(TFC) A membrane configuration in which a thin membrane film is supported by a thicker, more porous material.

Evaporator where liquid flows or is sprayed over heat transfer surfaces, usually tubes, in a thin, turbulent film.

A swinging gate in a sewer pipe that prevents seawater from entering the system during high tides.

See “transmembrane pressure”.

A unit of mass equal to 2000 pounds or 907.2 kilograms. Also called “short ton”.

A unit of mass equal to 1000 kilograms or approximately 2204 pounds. Also called “metric tonne”.

(TBT) The maximum temperature of the fluid being evaporated in an evaporator system.

(TDS) The weight per unit volume of all volatile and non-volatile solids dissolved in a water or wastewater after a sample has been filtered to remove colloidal and suspended solids.

(TS) The sum of dissolved and suspended solids in a water or wastewater. Matter remaining as residue upon evaporation at 103 to 105°C.

(TMP) The average pressure across a membrane, measured as the hydraulic pressure differential from the feed side to the permeate side.

Flat plate used to secure the ends of tubes in an evaporator, heat exchanger or boiler.
