The ARS process was developed and patented about 25 years ago together with the Technical University Hamburg Harburg. With this process, the sludge age of a biological treatment stage can be increased to over 20 days with little additional effort. This increased sludge age results in stable operation of the treatment plant, absence of odour and excellent accident management.

The reuse of treated wastewater and surface water can be supported surprisingly well by disinfection with UV radiation. In a 2-stage TIA soil passage, organic contamination as well as ammonium and nitrate are significantly reduced at low cost. The colony-forming germs are reduced by 90%.

For operation, monitoring and, if necessary, rough cleaning is only necessary from time to time.

A downstream LED-UV system sterilises the water to drinking water quality.

In countries where the reuse of used water is indicated, this system combination provides a cost-effective solution with almost no operating costs.

The effectiveness of this technology has been proven in a research project in cooperation with the Technical University of Ulm.

To increase the power density in wastewater treatment plants or, in multi-stage wastewater treatment plants for the degradation of refractory substances, TIA uses carrier materials in bioreactors in addition to the activated sludge (hybrid reactors).
Preferably, a movable, textile knitted fabric is used, which is set in stainless steel frame constructions. The TIA FLEXIFILM modules are resistant to clogging even at low flow rates. They can be retrofitted in deep or surface aerated aeration tanks with little effort and without interrupting operation.
For the loosely inserted support bodies in "moving bed bioreactors" (MBBR), only fillers are used that are abrasion-resistant and thus do not represent sources of microplastic emissions.

TIA Flexifilm wurde zur Leistungssteigerung von bestehenden Belebtschlamm-Anlagen entwickelt. Die Leistung der Anlagen wird nachweislich um bis zu 30% erhöht.
TIA Flexifilm was developed to increase the performance of existing activated sludge plants. The performance of the plants is proven to be increased by up to 30%. TIA Flexifilm is a flexible growth carrier for microorganisms that is inserted as a module into the existing wastewater treatment plant or placed on top as a floating element. TIA Flexifilm is installed without interrupting operation and without additional construction work or technical retrofitting.
TIA Flexifilm wird ohne Betriebsunterbrechung und ohne zusätzliche Bauarbeiten oder technische Umrüstung installiert.

TIA flotation plants are particularly suitable for the separation of substances such as fat or oil, for the separation of precipitated or flocculated substances and for the separation of unseparated sludge.

Plants made of stainless steel are available with a capacity of 2 to 120 m³/h, both with and without lamella technology. In concrete any plant with any capacity can be built.

The retention of bacteria in a biological treatment plant is often the weak point of the process. TIA has therefore developed the 2-stage clarification: Here, the normal sedimentation is followed by a separation via lamellas. This ensures the retention of biomass in the sewage treatment plant and thus the entire purification process. Furthermore, the 2-stage secondary clarification requires only 1/3 of the space of a conventional sedimentation. It is far superior to conventional sedimentation in cold and very warm areas.
Sie ist in kalten und sehr warmen Gegenden der konventionellen Sedimentation weit überlegen.
