Specification:

CSAF Units are supplied with gravity outlets as standard. If you require a pumped outlet option please contact us for a site-specific quote.

Options:

Invert Depths:

The standard invert depth is 1m. This can be increased by a maximum of 1m giving a total maximum depth of 2m. If selecting the 2m depth this includes 1m extensions for all the shafts on the tank.

Backfill Material:

There is a choice of tank shells suitable for either concrete or granular backfill (depending on ground conditions).

Ammonia (NH3) Levels:

Depending upon the site location, sometimes a lower Ammonia level is required by the Environment Agency. The CSAF units above 60PE have options of discharging either 20, 10 or 5 mg/L of Ammonia. 20 mg/Litre is the standard plant efficiency. Choosing an efficiency of 10 or 5 mg/Litre will extend the physical length of the plant and increase the size of the blower - please see the Operation Manual for details.

Sample Chamber:

A GRP Sample chamber can be provided with options of either 110 or 160mm pipework depending upon your site requirements.
