Tanks are typically used for break tanks and brine tanks.
Break tanks can be supplied with extras such as float-controlled inlet diaphragm valve, overflow, outlet and low-level switch for raw water pump protection.
Brine tanks tanks can be fed by gravity from bulk salt saturators via a normally-closed diaphragm valve, or the brine tanks can be hand-topped-up with salt. The brine tanks can be supplied with internals, typically consisting of brine level switches for the measured quantity of regenerant and a safety ball-valve float assembly on the inlet feed. Vent and overflow connections can also be provided.

These are specially-designed tanks for the water treatment industry.
They consist of a one-piece moulding, manufactured in MDPE, suitable for use with a range of chemicals (e.g. caustic soda, acids used in pH correction).

These tanks find extensive use as acid measure tanks for dealkalisation and demineralisation plants. The tank can fed by gravity through a normally-closed diaphragm valve from a bulk storage facility.
