At a minimum, one storage tank, one processing tank, and one oil-sludge tank are necessary. A processing tank should be large enough to handle at least one average day of flow. If the system is being set up for continuous flow, a series of cascading tanks with at least a half- hour retention time per tank is necessary.

A small laboratory bench with a dedicated pH meter and calibrating buffer solutions, a magnetic stirring mixer, chemicals used within the process and pipettes for measuring chemical additions are all good to have on site.

Truck spill containment may be required for oil hauling pump-outs by a contract service.

Dosing generally applies to feeding chemicals or medicines in small quantities into a process fluid or to a living being at intervals or to atmosphere at intervals to give sufficient time for the chemical or medicine to react or show the results.

In the case of human beings or animals the word dose is generally used but in the case of inanimate objects the word dosing is used.
