3. OPERATING & MAINTENANCE RECOMMENDATIONS
An annual service and maintenance contract should be set up for your MONOBLOCK system. Shall
this not be the case, consult a BIOROCK Certified Installer or a BIOROCK® trained and approved
company for the maintenance on your sewage treatment plant.
Contact your dealer if necessary or contact us for more details about the closest dealer to you.
The summary below indicates the commissioning of your sewage treatment plant.
Your sewage treatment plant can be free from any failures as the MONOBLOCK system does not
require electricity. (In normal operation, and following the maintenance recommendations)
GENERALLY:
Every year:
Visually check the water tightness of the MONOBLOCK at the inlet pipe
Check the ventilation
Check if there are any smells exiting the tanks
PRIMARY COMPARTMENT:
Every year:
Check the sludge level
Empty the Primary Compartment if the sludge level is > 50%
Rinse or change the effluent filter if necessary or change after emptying the Primary
Compartment
Take a sample of the effluent from the Primary Compartment and check quality
visually
SECONDARY COMPARTMENT
Every year:
Clean the water distribution system
Check the top layer of the BIOROCK media, clean if necessary (Cf. Procedure B/Ch 3.2)
Check and clean the alarm if necessary
Take a sample of the outgoing water (final effluent) and check for clearness and odour.
Clearness means that the water contains few suspended particles. The colour may vary
from neutral to dark yellow. The odour of the water will normally be neutral to light
ammonia.
