3.2. Maintenance
All measurements and events must be recorded in the operational log!
The extension of disposal intervals must be communicated to the relevant authority, if
required according to the applicable wastewater regulations.
3.2.1. Monthly self-inspection by the operator
1. Measure the oil layer thickness
2. Determine the height of the sludge level
3. Take a water sample and determine the pH level
4. Visually inspect the coalescence level and clean or replace, if necessary
5. Check for a potential difference in water level before and after the coalescence level
6. Check float for ease of movement and cleanliness; press the float down about 2 cm
and check whether it rises by itself; clean, if necessary.
7. Skim off floating substances.
8. Monitor formation of odours (thinners, waxes, etc.)
9. Check whether the water sample is closed tightly.
10. Check the warning and/or control system for cleanliness and proper functionality
according to the operating instructions of the alarm system.
11. Check potentially existing drain grate in the sludge trap for permeability and skim off
floating substances, if necessary.
The cleaning intervals must be arranged such that the storage capacity of the separator and
the sludge trap is not exceeded and the functionality is not interrupted. The separators must
be drained at a level of separated light fluid volume corresponding with 4/5 of the storage
capacity, and the sludge traps if they are at half level of capacity, however, both must be
drained at least semi annually.
