Introduction
The process used within the WCSEE SAF has been developed to meet the more
stringent discharge consents now being imposed by the Environment Agency,
particularly with reference to low ammonia levels. The HiPAF can achieve
ammonia standards better than 10mg/l.
The T300 and T3HP (for Hire Use) has been designed for above ground
installation only.
The T300 is equipped with an optional access ladder and handrails, where as the
T3HP does not require any top-level access. This is shown in more detail in the
next pages.
Blowers and controls to provide the air are housed in a separate standalone kiosk
adjacent to the plant. The tank and kiosk are manufactured in GRP for corrosion
resistance and long life.
*As these units are above ground and generally receiving pumped flows, it is
therefore necessary to provide suitable flow control before the effluent is received
by the unit.
The plant should receive Dry Weather Flow
as stated in the relevant quotation or
design documentation; ensuring adequate hydraulic retention time for the relevant
biological processes to take place.
WCSEE advises the following for lifting practices for the T300 & T3HP tanks:
Checks:
•
Inspect all lifting points and tension if required with a suitable tool.
•
The unit must be hoisted empty of all material and fluids.
Test lift the unit to check that the centre of gravity of the unit is in the correct
location (See drawing supplied by WCSEE LTD), and that all of the chains are
taut. It is critical to ensure a balanced lift, but if in doubt don’t lift the tank.
