5.2 General recommendations
Economical cleaning agent dosages
An increasing number of “strong cleaning agents” are available on the market, which contain
substances that feed on the oxygen necessary for the decomposition process and
compromise the decomposing bacteria.
The use of washing and cleaning solutions should be kept to a basic minimum in
order to achieve optimal decomposition.
Note:
Reduce the amount of solution until you are no longer completely happy with the
cleaning result, then gradually increase the amount you use.
This is especially important in households that use drinking water very sparingly and heavily
reduce consumption (to less than 80 l per inhabitant). As a result, the incoming wastewater
may enter the plant twice as concentrated as normal domestic wastewater and the outflow
concentrations may exceed the limit values stipulated by the authorities even if the plant is in
perfect technical and biological working order.
Running-in phase and purification efficiency
The full biological purification efficiency (= COD decomposition > 85%) takes several months
to develop and is only achieved if:
•
There are no structural defects (e.g. heavy underloading or overloading, extraneous water
inflow, faulty aeration and deaeration, installation faults)
•
It is certain that the domestic wastewater contains no forbidden substances (poisonous or
damaging substances: see the next page) and that it is characteristic domestic wastewater
(COD < 1000 mg/l; pH value = approx. 6.5 to 8.0)
•
The proper function of the aggregates is assured through regular maintenance; see
chapter “6. Monthly in-house inspection and half-yearly maintenance”.
Note:
Supervision of the running-in phase by qualified personnel is advisable. In the
running-in phase, SBR plants should be supervised and, where possible,
configured by a specialist company.
Building a stable biological function is a prerequisite for ensuring fault-free plant
functionality.
