Original Operating Manual for KLARO Small Wastewater Treatment Plant V.15.07
2.4. Exclusion for Use
The controller has been specially developed for use in SBR small wastewater treatment plants. The
controller must not be used in areas that pose a threat to life and limb:
•
Control of machines, vehicles, and safety processes,
•
Research technology in handling of hazardous substances,
•
Medical technology,
•
Nuclear power engineering,
•
etc.
3.
Warranty
The plant/conversion kit has been dimensioned and manufactured according to the state of the art. The
product has left the factory in a faultless condition. As part of the warranty, defects due to manufacturing
or the material will be repaired free of charge. These defects must have demonstrably occurred in spite
of correct installation and compliance with the conditions of use in accordance with these installation
instructions. After delivery, please inspect the controller for any damage. In the event of defects, please
contact your contractors/dealer immediately with a description of the defect and the plant identification.
Our terms and conditions are binding.
We expressly state that the warranty is void in the event of:
•
Improper installation,
•
Unconventional use,
•
Deluge,
•
Lightning and other overvoltages.

Function of the SBR Plant
KLARO and KLARO Easy are fully biological small wastewater treatment plants, operating on the
principle of the SBR process (activated sludge plant with sequencing batch reactor) . The SBR plant is
designed for the treatment of the entire household wastewater. The introduction of other wastewater, for
example, the wastewater from restaurants and/or business entities, etc., is permissible if this use was
already known and taken into account during the design of the plant.
Biocides, toxic, or biologically incompatible substances must not enter into the system as they interfere
with bacteria, important for wastewater treatment, and cause biological process problems (detailed
information found on the following pages).
Operation in accordance with our operating and maintenance instructions is essential for compliance with
regulatory treatment requirements. You can find these instructions on the following pages.
The system essentially consists of 2 stages: A sludge storage with integrated pre-buffer and an activated
sludge stage in a closed sequencing batch reactor (SBR).
The upstream sludge storage with integrated buffer has the following functions:
- Storage of primary and secondary sludge,
- Retention of settling solids and floating substances,
- Storage of feed water,

- Balance of volume and concentration-related fluctuations in the wastewater inflow.
The wastewater treatment plant operation takes place via a microprocessor controller, which controls the
air compressor and the air distributor for the various lifters via solenoid valves.
Your responsible Commissioner for Water Authority has established limit values for the water quality of
the treated wastewater. Accordingly, you have purchased a system with the process class that safely
complies with those limits.

The process is a sequence of 5 steps, which take place successively in time and are repeated several
times a day (usually 4 times).

Step 1 (valve 1): Charging
-
The raw wastewater temporarily stored in the sludge storage is fed to the SBR via an airlift. The
airlift is positioned so that only solid-free water is pumped. Through the special design of the
lifter, a minimum water level is guaranteed in the sludge storage. Limiting the water level through
other components (e.g., a float switch) is therefore not required.
