The following research topics are focus by the innovation network S3Rem:
sewer network management
intelligent control systems für water management
advanced treatment of sewage plant effluent
treatment of sewage sludge
energy efficiency of wastewater treatment process
The S3Rem innovation network is working on various projects that are in different phases. The approved projects are listed below. Further project information can be found on the linked project homepage (for newly approved projects as soon as it is completed.)
pharmIn2 aims at introducing the a3op® technology of the company up2e! for cleaning wastewater from the pharmaceutical industry in India. A pilot plant adapted to local conditions should enable interested customers to carry out pilot projects, demonstrate the technology’s efficiency and acquire orders for the construction of complete plants in India. The marketing is accompanied by a publicity concept, which is tailored to the local needs and includes various advisory and networking offers.
The aim of the project UVPHON is the UV-LED-based process technology for wastewater disinfection, innovatively and sustainably adapted, optimized and further developed into a demonstrator as a preliminary stage of a market-ready system. Until now, UV LED technology has primarily been used in drinking water treatment, since excessive turbidity and the associated UV absorption in the water matrix of treated wastewater can reduce its effectiveness and therefore make its use uneconomical. This limitation is to be eliminated through the development of an optimized reactor design, the additional treatment step of filtration, the combination of UV LED disinfection with photooxidation, and intelligent process control and management using online sensors. With the further development of the control and the combination of treatment steps, the previous limitations in the application are eliminated and the safe and cost-efficient reuse of wastewater is made possible. .
The aim of the IntelliFluQs project is the development of a web-based, multi-criteria, flexible control system that can be used or adapted for different processes in the fourth cleaning stage, which on the one hand aligns the cleaning process with desired target criteria and on the other hand predicts the operator through forecast analysis which wastewater qualities will occur with optimal energy consumption depending on the raw wastewater quality are reachable. In accompanying investigations, the necessary correlations between the common wastewater parameters and selected trace and micro-pollutants are to be determined.
For the first time, the linking of the fourth purification stage and renewable energies is to be tested in a small/medium-sized sewage treatment plant. Energy-intensive cleaning technologies such as ozone or membrane technology have so far only been considered for larger to large sewage treatment plants (> 50,000 PE), although the environmentally beneficial effects on the small, sensitive bodies of water can be assessed as enormous. Many small bodies of water are used, for example, as feed water for natural fish ponds, and the appropriate quality must be ensured. This project is not just about providing the additional consumption of energy through a fourth cleaning stage using renewable energies, but also to determine how control geared to energy consumption, system performance and use of generated energies must look like for optimal energy efficiency while complying with the cleaning targets, so that the comprehensive use of a fourth cleaning stage becomes affordable. In order to obtain a comparison with the conventional actual state, a conventional activated carbon stage is used in addition to the innovative membrane and fabric filter.
