This is a process by which a porous carbon can be coated with a biocompatible polymer to give a smooth and permeable coat without blocking the pores. The resulting carbon is ...
hydraulic retention time (HRT
Environment; Pollution
The hydraulic retention time (HRT), also known as hydraulic residence time or t (tau), is a measure of the average length of time that a soluble compound remains in a constructed ...
solids retention time (SRT)
Environment; Pollution
The Solids Retention Time (SRT) is the average time the activated-sludge solids are in the system. The SRT is an important design and operating parameter for the activated-sludge ...
