KLARO One small wastewater treatment plant
KLARO One is the latest development in fully biological wastewater treatment plant from KLARO. It operates based on the tried and tested KLARO principle: No pumps, or mechanical and electrical parts in the wastewater. KLARO One offers maximum flexibility for new construction or retrofit.
KLARO One stands for ...
- Large buffers, designed for the total daily volume
- Automatic level measurement
- Excellent effluent values
... sophisticated technology
- Microprocessor control
- Whisper quiet stepper motors
- Plug & Play retrofit kit
- No putrid odours
... low running costs
- Low level of sewage sludge
- Minimal power consumption
- Minimal maintenance
Flexibility in installing
KLARO One is constructed in a way, that it is possible to install the system in nearly every tank.
- Can be installed for a new construction or as retrofit in existing pits
- Can be retrofitted to 1, 2, 3 or 4 chamber pits
- Suitable for round and rectangular pits
- Can be used in tanks made of different materials (concrete, plastic, fibreglass, ...)
Components of the KLARO One
Two (or more - depending on the number of chambers) newly developed aeration beams are used in every variant of the KLARO One. The membrane is protected from damage by high quality stainless steel braces.
Components in a single chamber pit
A customisable partition is used in the single chamber pit, which leaves sufficient space below for the transfer of water and sludge.
Sludge disposal tube
The disposal operator draws the sludge through here. The inlet is arranged so that sufficient seed sludge always remains in the system.
Components in a two or more chamber pit
In the two, three or four chamber pit the transfer of the wastewater occurs through at least one hole in the dividing wall. In the second chamber a plate protects against excessive turbulence through the incoming water.
Prepared for every situation
The KLARO One is controlled via the new step motors, which are most of all characterized by low power consumption, silent operation and low maintenance.

KLARO One measures the fill level with a pressure sensor and thus monitors the flow situation. Consequently the system can respond optimally to the current conditions (underload or overload) and adjust purification accordingly.
If there is little or no flow, or the fill level is low, the cleaning cycle is not run and only slight aeration applied. As a result both electricity is saved and the cleaning performance is maintained. With the automatic underload detection, the run time of the plant automatically adjusts itself to the actual amount of wastewater.
If the flow is raised or too high and the fill level is too high, the cleaning cycle is stopped and the settle phase automatically initiated. The activated sludge settles out. A clear water zone forms in the upper part of the activated phase. This is followed by clear water discharge. Therefore this prevents sludge drifting away with overloading or unpurified wastewater being drawn off with excess backwater.
The SBR cycle
KLARO One is a fully biological wastewater treatment plant, which basically consists of an aerobic treatment stage after the sequencial batch reactor (SBR) process. This treatment stage is divided into a pre-treatment stage and an aeration stage, which are interconnected by an overflow.
1. Aeration phase
The raw sewage enters the pre-treatment stage and directly undergoes aerobic purification. Through the aerobic purification activation of micro-organisms occurs.
2. Settle phase
When aeration is interrupted by the control system the activated sludge settles to the bottom. A clear water zone forms in the upper part of the container. If raw sewage enters into the system during this, it is retained by the dividing wall or baffle in the pre-treatment stage.
3. Discharge phase
In the final purification step, the clarified wastewater from the aeration stage is removed by means of a compressed air lift. The purification process can start over again.
Save money with the KLARO One
Minimal power consumption
KLARO One saves power in operation. The small number of airlift operations, and the use of step motors reduces power consumption dramatically.
Low level of sewage sludge
The aeration of the entire wastewater leads to immediate activation of sewage. The formation of sludge is reduced to a minimum, therefore extending emptying intervals. Disposal costs are reduced.
Low maintenance costs
The high-grade components of KLARO One are characterised by quality and robustness. The parts are arranged so that the time required during maintenance is minimized.
