High efficiency - small space requirement
The FSM compact unit type KSF-L combines high efficiency with a very small space requirement. Type KSF-L is designed for flow rates of 100 l/s and higher.
For an inlet flow of 100 l/s the required area (without classifier screw) is 11.5 m².
The plants are designed in fixed sizes. A tank length of 1 m corresponds to a flow of 20 l/s. Intermediate sizes are covered by different numbers of lamellas.
The outlet trough extends over the entire tank length. This results in a low weir load with the advantage that the water is not flushed into the following processing stage.

Functional principle:
The waste water is pumped or flows freely into the flume of the screen, where it is cleaned. The screenings discharged, de-watered and compacted. In this process, the water flows through the screen, where coarse material is retained. The screen unit is resistant to grit and stones. FSM`s proven machine components are used for the screen and the compactor.
The non-aerated grit separator is  designed in accordance with DWA-Standards in respect of separation of mineral superfines. Mechanical grit conveying is achieved via a screw conveyor.

A grease trap with fine bubble aeration generating an air roller is located upstream of the grit chamber.
The inlet flume extends over the whole length of the compact installation and at the same time forms the grease trap. Disk aerators connected to a blower are located at the side of the grease trap. Waste water flows from the grease trap to the grit chamber via an opening in the lower area of the grease flume. The floating grease collects in the grease trap and is is directed into a collection hopper by a scraper.
A pump removes the grease discontinuously so that it cannot get into the grit chamber.
The grit chamber is fitted with lamella technology and is designed in accordance with the German Standard DWA for non-aerated grit chambers.
It is not necessary to supply additional energy for the grit separation.
The separated grit is collected on the tank bottom. The grit is conveyed to a grit pump or a grit screw classifier by a spiral conveyor.
The installation can be provided at low cost with an emergency by-pass system. For this purpose, a manually cleared screen is incorporated in the screen container and an additional connection to the outlet flume of the grit separator established. It is not necessary to use long piping with high space demand.
