Fill the pit with crushed stone (0-16 mm diameter), at least 50 cm all the way round, compacting the filling material prop-
erly every 30 cm to 97% Dpr (e.g. using a vibratory plate compactor).
At the same time, fill the tank with water so that the maximum difference between the liquid level and the level of the
backfill material is 30 cm.
The required excavation pit slope angle β must be observed all the way round.
The internal friction angle φ of the backfill material and allowable excavation slope angle β must be assigned in accor-
dance with DIN 4124.
(1) Subbase (crushed stone)
(2) Tank bed (sand)
(3) Separator according to the structural calculations
(4) Back fill material (crushed stone)
5 Commissioning and functional check
Preparing commissioning
Connect water supply if necessary.
Fill separator with cold water up to the static level (level of the outlet).
Have a general inspection carried out (during initial commissioning and then every 5 years).
Give safety instruction.
File all records in the log book and document required disposal cycle.
All documents must be kept available at the system. The local supervisory authority can ask to examine the documents.
6 Operation
The grease separator separates grease, oil and sludge from the wastewater. Different methods are used to empty the sep-
arated substances, depending on the system type. The available versions of the EasyClean ground Oval (Standard and
Direct) are purely mechanical system types and therefore do not require any further description of their operation.
Separators for grease should be serviced, emptied and cleaned regularly. You are reminded of the need to comply with
national or local regulations concerning waste disposal. The intervals for servicing, emptying and cleaning must be defined
taking into account the storage capacity of the grease separator and sludge trap as well as the relevant operating experi-
ence. Unless specified otherwise, sludge traps and separators should be emptied, cleaned and filled with fresh water again
once a month, or preferably every two weeks.
