Variety of applications
Independent of tank geometry and material
KLARO technology is largely independent of geometry and material of the clarification tank. The volume can be distributed over single or multiple tanks or chambers. These tanks/chambers can be round or rectangular. The only decisive factor is that certain minimum volumes and fill levels must be maintained.
Many plants are still constructed in the classic concrete tank design. However, tanks made of plastic are becoming increasingly popular even in large clarification plants and are steadily gaining ground. In this field, KLARO can draw on a large portfolio of first class plastic tanks manufactured by the GRAF group. For large-sized clarification plants, the tank types Carat 6,500 l, Carat XL 8,500 l, XL10,000 l and XXL16,000 l to 102,000 l come into question.
We provide independent and project-specific advice on advantages and disadvantages – the decision is up to the customer.
According to the requirements or structural engineering conditions, the KLARO sewage technology can be accommodated within various tank arrangements.
KLARO offers complete sewage treatment plants in prefabricated tanks, which can be delivered pre-assembled to the construction site.

Existing clarification tanks can also be incorporated in the new concept, if their holding capacity is not sufficient for the entire plant. In that case, new tanks can be added downstream of the old tank. The existing tanks are mostly used as sludge storage/buffer tanks and the new ones are used as SBR’s, since they can be delivered immediately in practical, pre-assembled condition.

Conversion of existing septic tanks is also possible if holding capacity and basic fabric are in okay condition. KLARO technology is essentially well suited even for renovation and conversion of old plants using other processes.

KLARO plants can be expanded subsequently and more lines can be added. In such projects, we plan a central sludge storage/buffer tank which absorbs the complete inflow. From there, the wastewater is distributed over the other sludge storage/buffer tanks via underwater connections. The raw water with its solids can thus be distributed uniformly over the various lines/expansion levels in the easiest possible way.
Fields of application: e.g. site development of a residential area, holiday village, hotel, camping park.

Additional buffer tank
When designing a clarification plant, the maximum daily wastewater generation must generally be taken as a basis, even if this only occurs on a few days (e.g. restaurants on weekends). This results in such clarification plants being relatively large-sized and not being filled to capacity most of the time. We recommend an additional buffer tank to intercept such peak loads. In overload situations, it fills up automatically with mechanically pre-treated wastewater from the primary chamber. The storage tank is then automatically processed later once the required capacities are once again available.
Peak loads are equalised; the biological stage can be dimensioned to make it smaller
Fields of application:
- primarily gastronomy, e.g. popular restaurant destinations

A multiple line plant concept comes into consideration if there are strong seasonal fluctuations. The inflow is directed into a common sludge storage/buffer tank, followed by two or more independent downstream SBR reactors (lines). The lines can be equal in size or can vary. They are operated independent of each other via separate controllers. In off-season, one lane can run in economy mode or stopped completely.
- demand-oriented, economical operating mode
Fields of application:
- primarily gastronomy, e.g. hotels, camping parks
