Klawa Anlagenbau GmbH products

Ponds used to store service water, for instance to fight fires, are not an unusual occurrence in rural parts of Germany. Rainfall and surface water fill these ponds. We can make these systems ready for you to use at any time with the right engineering technology. For your peace of mind.

Wells collect water from aquifers and have technology based upon pumps and pipes that includes measuring and control devices This equipment pumps water upwards. KLAWA provides you with all of these systems in excellent quality and from a single source.

Central water supply systems often feature elevated tanks whose water table lies above the service territory. These elevated tanks help to offset fluctuations in consumption, maintain even pressure within the supply network, store water for fire-fighting purposes and act as a reservoir for booster stations. Elevated tanks have an important role to play in storing and distributing water and need the right engineering to do so. Our references and satisfied customers prove that KLAWA is the company to trust.

Rain storage reservoirs temporarily hold back rainwater that has entered the sewers. They help to relieve the pressure on the sewer system in the event of heavy rainfall. Cleaning the reservoir basin and controlling discharge are repeatedly a source of problems. This is where KLAWA comes into its own with the KLAWA Light drainage control system and a variety of flushing and cleaning systems.

Special measuring and control equipment is used to prevent hydraulic overloads at downstream sewer constructions and at wastewater treatment systems A number of options exist that frequently contain many components so they are costly and require a lot of maintenance. But the KLAWA Light drainage control system embraces simplicity. Its simple design features three standard components: an ultrasound flow measuring device, a sealing device and a rotary actuator.

Spiral pumps or wastewater pumps and their pipelines transport material at pumping stations. Technology installed at the pumping station moves the material more or less evenly to the downstream sewage plant. KLAWA has installed this equipment at many pumping stations and has a wealth of experience in this particular business.

Screening units are one of the oldest wastewater cleaning devices. Many different types have been developed and rejected over time. And today, development work continues to make progress. Grit washing plants are another technical solution for mechanical cleaning. Wastewater is treated to extract grit from the inflow and send it for recovery. Organic substances are removed from the water. Washed grit falls into the container and is then put back in the economic cycle. We use wastewater technology components from well-known manufacturers in our projects and integrate them into our processes.

Biological cleaning is at the heart of a sewage plant. This is where microorganisms break down organic substances in wastewater and inorganic substances are partially oxidised. Substances are broken down by adding oxygen and mixing it through the wastewater in aeration basins. The detachable KLAWA aeration element is one tried-and-tested technical option for aeration. These elements are assembled to each customer’s specifications and we attach great importance to maximum efficiency in aeration. You can find a few examples of how we have implemented these elements on this page. We would be delighted to design an option tailored to your location

After leaving the aeration basin, biologically cleaned wastewater and activated sludge enter final sedimentation. The role of final sedimentation is to separate the activated sludge from the water. Pump technology and scraping devices return sludge deposits to the aeration basin and send them for additional sludge treatment or for waste management. We manufacture and assemble the scraper bridge and suspensions to customer specification. All components made by suppliers come from well-known companies. We promise to perform proper and professional repairs rapidly if you find that the bottom scraper blade (seal) malfunctions during operation. A number of references pay testimony to our expertise and reliability. That goes for service and maintenance too.

Polishing ponds or pond treatment plants are one of the oldest methods of wastewater treatment. These ponds contain wastewater that has been fully cleaned using biochemical methods. Their job is to “polish” this wastewater, for instance by filtering out more sedimentation. A distinction is made between naturally and technically aerated wastewater ponds. We always have the perfect solution ready just for you - from fixed bed reactors to jet injectors and special aerators. And our ground sludge remover takes away sediment deposits that form during operation.
