KLARO containerized wastewater treatment plant
The mobile solution for wastewater treatment
Mobile container wastewater treatment plants for rapid deployment
KLARO Container is a flexible and mobile wastewater treatment system that can be used where a wastewater treatment system is required but there is no connection to the sewer system.
KLARO containerized wastewater treatment systems score with their quality made in Germany, flexibility and efficiency. Individually planned and produced, they can be quickly assembled, dismantled and re-installed at a different location using the plug-and-play principle. The systems can also be installed for permanent use.
The four different variants of KLARO containerized wastewater treatment plants offer the necessary flexibility in the design of wastewater systems. They can be used for a wide range of applications:
- Refugee camps
- military camps
- Labor and research camps
- construction sites
- Municipalities
- Seasonal tourism/camping
- Oil and gas industry
Advantages and features
Quality
made in Germany
KLARO containerized wastewater treatment systems are all manufactured, pre-assembled and tested at our site in Bayreuth. You can rely on the top quality of all installation parts. Thanks to the high-quality workmanship, the systems can be operated in any climate zone.
Easy to transport
The wastewater treatment plant is housed in one or more sea containers whose dimensions and structure comply with global standards. This means that the containerized wastewater treatment plant can be transported on any vehicle that can be loaded with sea containers.
Prefabricated
construction
At our factory in Bayreuth, the containerized wastewater treatment plant is pre-assembled, tested and prepared for transport as far as possible. The plant then only needs to be commissioned on site.
Fast
assembly and dismantling
Our containerized wastewater treatment systems are connected according to the plug-and-play principle: The installation material such as hoses, pipes and cables are optimally matched to each other. If necessary, the system can also be quickly dismantled and installed at a different location.
Simple
operation
The KLARO containerized wastewater treatment plants not only impress with their quick plug-and-play installation, but also with their simple operation. The mobile plants are designed in such a way that staff can easily operate and maintain the system. The system operates fully automatically and adjusts itself to the wastewater volume thanks to its energy-saving mode.
Low
costs
No planning or buildings are required to operate a containerized wastewater treatment plant - the plant simply needs to be placed on a solid base. This saves costs in advance, and the system is also highly efficient during operation: a 20-foot container only needs 13 kWh/d.
Modular
Expandable
We offer four different
containerized wastewater treatment systems to choose from:
Container.One, Container.One+, Container.Pro and Container.Xtra. All have a modular design and can therefore be expanded. Basically, 10, 20 and 40-foot containers are available. For larger wastewater volumes, several containers can be linked together, giving you the greatest possible flexibility. We have experience with containerized wastewater treatment plants for up to 1,380 PE or 207 m3 of wastewater per day.
Individual
System design
A wastewater treatment plant is only as effective and efficient as the installed system. That is why every containerized wastewater treatment plant is planned and produced to meet your exact requirements and conditions on site. In addition to a complete system in a container, containers are also available with different treatment stages, e.g. as primary treatment stages, biological stages, secondary treatment stages or as sludge treatment stages.
Variants of the KLARO Container wastewater treatment plant

Example Container.One: The treatment stages
Our Container.One plant works fully biologically according to the so-called SBR process (= activated sludge plant in the impoundment process).
In contrast to models from other manufacturers, the sludge storage tank and buffer are already integrated in the plant.
Wastewater treatment takes place in the following steps:
1st aeration phase
The raw wastewater, which is pumped to the container via a pumping station, enters the front area of the container and is immediately treated aerobically. The microorganisms in the activated sludge are supplied with oxygen, thus purifying the wastewater.
2nd settling phase
After aeration is complete, the activated sludge can settle by gravity. This creates a clear water zone in the upper part of the container. Incoming wastewater is held back in the front area with the aid of the baffle.
3. clear water discharge
In the final step, the clarified wastewater is discharged via a discharge device in free fall. The discharge device is backwashed shortly beforehand.
Components of the container.one containerized wastewater treatment plant
1. technical room
The protected technical room with the electromechanical components (control unit, compressor and air conditioning unit) is located at the front of the container sewage treatment plant. The system is controlled from here. The KLARO WebMonitor can be booked as an option to enable remote maintenance of the system.
2. aeration
The aeration unit of the containerized wastewater treatment plant consists of submerged membrane aerators. These ensure optimum mixing and fine-bubble aeration of the system. They are mounted on a stainless steel pipe.
3. decanter
The clear water is drained from the system via the decanter. A shut-off valve is fitted to this drainage device. As soon as the flap is opened via the system control, the water can flow out. To prevent sludge from being carried away, the device is backwashed shortly before the discharge.
Optional additional modules
Depending on your requirements, KLARO containerized wastewater treatment plants can be expanded with a range of additional modules. Whether for optimizing the water quality, for reuse or for system control via remote control technology - we optimize the system to your needs.
Pump shaft
The wastewater produced must be pumped/conveyed into the container installed above ground. KLARO offers optional ready-to-connect plastic sumps with sewage pumps for this purpose. The buoyancy-proof plastic sump offers flexible connection sizes.
Available as a single or double pumping station.
Sieve screw
Optional for installation on the container roof
- Connection upstream of the container inlet - wastewater from the pumping station first enters the sieve screw before it flows into the container system
- Separation of solids in the wastewater
- Impurities can thus be retained and do not enter the container system - increased operational safety
- Consists of a screen basket in which solids are retained and a spiral that transports the solids out of the screen basket
- Separated solids are conveyed to the side into a container
KLARO WebMonitor®
Remote monitoring, remote maintenance and remote control in the field of wastewater treatment technology will become increasingly important in the future. The KLARO WebMonitor® can be used wherever maximum operational reliability is required - and to relieve the operator. The system can be monitored by a maintenance company using remote diagnostics. Intervention in the event of faults is possible immediately.
- Cost-effective remote diagnosis in the event of a fault
- Greater effectiveness
- Greater operational reliability
- Optimized service intervals
Phosphate precipitation
The use of an additional dosing pump, which feeds a special precipitant into the SBR tank, regulates the phosphate content of the wastewater. This variant has also been tested and approved for use in sensitive areas.
- Complements the modular concept
- Retrofitting possible
- Long service life thanks to simple technology
- Easy to maintain
- Dosing easily adjustable
Reuse KLARO blue.cycle®
One of the biggest challenges in wastewater treatment today is finding solutions for the reuse of treated water. The aim is for the water used in wastewater treatment plants to be reused directly, e.g. for watering gardens.
KLARO blue.cycle® is the result of a long and intensive period of development by KLARO and stands for innovative solutions for disinfection and reuse, designed as an extension for wastewater treatment plants.
The KLARO blue.cycle concept is based on a chlorination process. Chlorination is the world's most established method for effectively killing many pathogens present in wastewater and inhibiting their regrowth through its long-term effect.
UV module
Water and environmental protection for sensitive areas with the highest requirements. During clear water discharge, the treated wastewater is subsequently irradiated intensively with UV light. This inactivates the remaining bacteria and eliminates pathogenic germs.
- Easy to retrofit
- No environmental pollution
- Simple handling
- Low operating costs
- Integrated into the machine room
Sludge dewatering
Excess sludge forms during wastewater treatment in the container sewage treatment plant, which must be regularly removed and disposed of. With the KLARO module, the sludge is dewatered and dried on site. Volume and mass are reduced by up to 95%. This also reduces disposal costs and makes transportation easier, even from remote locations. The sludge dewatering unit consists of two parts: The pump unit is used to remove the excess sludge, e.g. as part of regular maintenance. A flocculant is automatically dosed and added to the sludge. The filter unit dewaters the sludge and dries it - it is covered and aerated in the filter unit during the drying process.
What is a containerized wastewater treatment plant?
A containerized wastewater treatment plant is a wastewater treatment system that is fully integrated into a container. For uncomplicated and fast transportation, we use 10, 20 and 40-foot shipping containers in accordance with the international ISO standard for our KLARO container systems. Container sewage treatment plants are mainly used for short-term use in remote areas that are not connected to a sewage system, in camps and on construction sites.
Thanks to their high-quality workmanship and equipment, the mobile container sewage treatment plants are also suitable for permanent use, for example in places that are difficult to reach and where no other connection to the sewage system is planned. You can find more information, including information on how they work and their technical features, in our brochure available for download.
Areas of application for containerized wastewater treatment plants
Refugee camps
The challenges in refugee camps are huge - especially when it comes to wastewater treatment. In most cases, refugee camps are set up very quickly and out of the blue; such crisis situations are rarely planned. Improvised tent cities are set up on undeveloped and undeveloped land, without infrastructure and without sanitary facilities.
In disaster situations, the disposal and treatment of faeces often takes a back seat. Temporary latrines or toilet facilities are set up, which are anything but optimal: Surface water and drinking water become contaminated, and the simple facilities without wastewater treatment and disinfection encourage the spread of disease. The people in the refugee camps are protected by the use of mobile container sewage treatment plants.
Our containerized wastewater treatment plants are available within a few weeks. Thanks to their modular design and pre-assembly at the factory, they are easy to set up and put into operation - a level, dry surface is all that is needed to set up the plant.
The mobile wastewater treatment plants are easy to operate, so that even the helpers on site are able to operate the plants after a short training course. Most of the processes run fully automatically.
Quickly available, quickly set up, easy to operate - therefore perfectly suited for this area of application.
Military camps
Camps of various sizes are set up for the military, especially during foreign deployments, and are usually expanded over time. German regulations also require efficient wastewater treatment abroad. Thanks to the modular design of KLARO's containerized wastewater treatment plants, each wastewater system can be expanded or supplemented as required if stricter hygiene regulations come into force.
Another challenge in military camps is the safety requirements that also apply to the installed wastewater systems. We therefore provide the operator with complete documentation listing all system components and their functions to ensure compliance with regulations.
Workers' and research camps
Whether in a mining camp or a research camp in the jungle: where many people are working and there is no infrastructure in the form of a sewage system, mobile and uncomplicated solutions are an ideal replacement - such as our container wastewater treatment plants. Thanks to their compact size, they can be delivered to almost anywhere in the world. All that is required for installation is a dry, level surface; in most cases, a foundation is not necessary
Our containerized wastewater treatment plants can be delivered quickly and are easy to operate, so that local staff can look after them themselves after a short briefing. They are pre-assembled in the factory so that final assembly on site is quick and uncomplicated.
Thanks to their high quality, the technology and other components of the system can also withstand extreme conditions such as high temperatures or high humidity.
Container sewage treatment plants that are installed at higher altitudes with lower air pressure are adapted to the climatic conditions so that sufficient oxygen is available, which the bacteria need to grow and purify the wastewater.
Construction sites
Our containerized wastewater treatment plants are not only installed in hard-to-reach places abroad, but also offer the perfect solution for short-term, temporary wastewater treatment in Germany. Typical locations are large construction sites where many people work for months or years and where there is no connection to the sewage system.
The wastewater can be purified to such an extent that it can seep underground or flow into a nearby receiving watercourse.
Municipalities
Municipalities often rely on containerized wastewater treatment plants during renovation work on existing wastewater systems, but also use the flexible systems as a permanent solution. Existing systems can be easily extended with KLARO containers.
Our containerized wastewater treatment plants also offer an effective solution for non-compliance with limit values. Thanks to the modular design, the mobile wastewater treatment plants can be combined with each other, enabling wastewater solutions for up to 1,300 residents - from the compact Container.One system to the high-performance Container.Pro solution.
Seasonal tourism/camping
Short-term or particularly flexible solutions for the treatment of wastewater and faeces are also required in other sectors. Examples include campsites or tourist hotspots in hard-to-reach locations that are only operated seasonally and do not necessarily require a connection to the sewer system. Of course, temporary toilets can also be set up here. However, a professional sewage treatment plant offers visitors and operators more comfort and safety while maintaining the highest hygiene standards. The only requirement for the installation of a container sewage treatment plant is a level and dry surface on which the plant can be set up.
Oil and gas industry
The number of employees in gas and oil fields fluctuates greatly depending on the production in the respective region, and therefore the amount of wastewater also fluctuates. At the same time, wastewater treatment must comply with the strict regulations of the oil companies, which focus on environmental protection. As the oil and gas industry usually operates in remote locations without a sewer connection and is often relocated, wastewater treatment can be a challenge.
Our containerized wastewater treatment plants are the ideal solution for these requirements. We plan and install them to suit the wastewater produced and its contents, as well as the desired degree of purification. If required, the mobile container sewage treatment plants can be easily extended, reduced or relocated.
Wastewater treatment plant damage in the event of a disaster
Natural disasters such as floods or earthquakes can cause considerable damage to infrastructure - including wastewater treatment plants and sewage networks. In such cases, KLARO containers offer a quickly deployable and reliable interim solution to ensure wastewater disposal until regular systems are restored.
