Only use 45
o
bends (never use 90
o
bends)
The ventilation pipes must have a minimum diameter of 100 mm
The Primary Tank vent pipe must be independent of the properties soil vent pipe
The water inlet pipe of the Primary Tank should be plugged or capped (blocked for air)
Always check the ventilation with a smoke test in representative conditions
(calm weather and storms are not representative conditions)
5.2 VENTILATION OF THE BIOROCK® TREATMENT UNIT
The BIOROCK treatment unit has a separate ventilation system
The vent pipe for the BIOROCK unit must be independent of the properties soil vent pipe and
must not be combined with the Primary Tank vent pipe.
The aeration of the both the upper level and the middle section of the treatment unit is combined
The air intake is located at the front of the treatment unit
The air outlet pipe should always be equipped with a wind driven or electrical ventilator
The ventilation pipes must have a minimum diameter of 100 mm
Only use 45
o
bends (never use 90
o
bends)
Always check the ventilation with a smoke test in representative conditions
(calm weather and storms are not representative conditions)
If the ventilation is not working properly:
Check the ventilation system again by following the diagram
Check if the pipe work is obstructed or disconnected at any stage
Check if the air outlet pipe is positioned high enough
Check that the wind driven ventilator has enough capacity, otherwise change to an electric
Ventilator
5.3 WATER DISTRIBUTION PIPE
Make sure the BIOROCK® Media is saturated with clean water
Check and adjust the water distribution pipe to ensure an even distribution across the
BIOROCK® media
Adjust the height/level of the water distribution pipes using the threaded supports
The discharge angle can also be adjusted by twisting the pipes
Make sure that the BIOROCK® media is completely saturated with water
DO NOT completely fill the tanks with water before unit is backfilled
DO NOT use dirty or contaminated water
Check the connection from the Primary Tank outlet pipe to the BIOROCK® treatment unit
There should not be any accumulation of water within the BIOROCK® unit
Water should not accumulate on top of the BIOROCK® media
The level of the BIOROCK® media must be just under the water distribution pipe
Check that the water from the Primary Tank flows by gravity into the BIOROCK® unit
