3.2 THE ECOROCK® TREATMENT UNIT
The 10 years warranty shall only apply if the annual maintenance is carried out by a BIOROCK®
approved installer or supervised by a trained BIOROCK® Certified professional
MAINTENANCE PLANNING FOR THE ECOROCK-5000 SEWAGE TREATMENT PLANT
Only take a sample from running water.
Never use a sample from stagnant water
Effluent sampling:
6 months after start-up, then every year
Only take a sample from running water. Never use a sample from stagnant water
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
Sampling can be done via any sampling point or directly at the outlet of the tank
Always wear rubber or latex domestic gloves when taking a sample
The outgoing water should be clear. A little deposit might show at the bottom of the sampling
glass after it has rested for twenty minutes
The water shouldn't have a septic or nauseating odor. It may have the characteristic smell of
fresh humus
If the visual check seems to show a malfunction (turbid treated water, presence of deposits or
suspended matter, nauseating or septic odor), take the sample to a certified laboratory for
testing
If the laboratory confirms a problem with the water quality check:
-
if the primary tank is functioning properly
-
the quality of the pre-treated water from the Primary Tank
-
if there are any fats or solids on the surface of the BIOROCK® Media
-
the water distribution in the BIOROCK® unit
-
if the ventilation of the Primary Tank is functioning properly
-
if the ventilation of the BIOROCK® system is functioning properly
-
if the unit is correctly sized for its required capacity
-
the presence of harmful, toxic, antibacterial or non-biodegradable products in the
installation
If you notice the presence of increased deposits (suspended matter) in the treated waste
water or if the unit is clogged up:
A prolonged overload of pollution in the installation, repeated misuse of the primary tank
(late sludge removal, an inefficient effluent filter and neglect over several years) can lead to
the saturation of the BIOROCK® Media in the bioreactor.
