4.9 Emptying and cleaning the light liquid
separator
The plant (separation chamber) must be drained and cleaned at least once a month by properly
qualified, competent people Chapter 1.5 “Personnel qualifications".
IMPORTANT
■
The country-related regulations must be complied with.
■
Emptying should be implemented immediately when:
The volume of separated light liquid has reached 80% of the maximum storage
capacity volume,
when the separated sludge volume has reached half of the sludge capture volumes,
before a general inspection.
■
Drainage must be carried out immediately when the quantity of separated light liquid
has reached 100% of the maximum storage capacity. As the switching on of the
submerged pumps in the pumping station is blocked by this message, the inflow of
wastewater into the plant must be prevented until after the emptying process. Otherwise
there is a risk of light liquid escaping from the maintenance opening!
■
Enter the date and address of an approved waste disposal company in the
operating log.
■
The resulting disposal volume is 1.15 x the total volume of the plant.
Ensure that the disposal vehicle is large enough. Total content,

4.9.1 Execute draining and cleaning
IMPORTANT
■
Before the separator chamber is emptied, the contents of the pump station chamber
must be removed or manually pumped into the sewer.
■
Sensors removed for cleaning must be in their original position after insertion,
chapter 3.4.5 "Mounting idOil sensors".
■
Direct extraction for separator chamber can be obtained from ACO as an optional extra.
■
For the purposes of filling the plant, surface water or process water can be used
as well as fresh water, providing it complies with the local discharge conditions. If
wastewater from the disposal vehicle is to be utilised for refilling, then compliance
with the municipal limiting values for the wastewater must be documented
accordingly. The disposal company must submit the relevant documentation to the
owner or operator.
