Modular Lightweight Wastewater Treatment Plants Made of Textile Reinforced Concrete—Means to Reliable Wastewater Treatment in Rural Areas
The safe supply of clean water is of such prominent importance that it is even defined by the United Nations Sustainable Development Goal 6 “Clean Water and Sanitation”. In order not to lose sight of those regions, outside the conurbations, that are difficult to access, wastewater treatment plants (WTP) must adapt to new requirements. As a novel material, textile reinforced concrete (TRC) opens up new possibilities to ensure the treatment infrastructure. A solution that can be used on a large scale requires consideration of the composite material, adaptation of the structure design to the requirements of material, process and load as well as the economic consideration of manufacturing, distribution and sales. The focus here is on a modular product solution. In this way, the low weight of the TRC components in transport can be fully utilised. The operating loads are defined in accordance with conventional WTPs. The life cycle loads from production to operation are included in the structural simulation and design development. Based on this, the requirements for textile reinforcement and concrete are deduced. Both single components as well as the composite material are evaluated with mechanical testing, regarding their suitability for the present application. Six compositions of matrices and four varieties of textiles with two different types of coatings in each were examined. TRC composites were prepared and tested for the best combination of these materials. Numerical models, based on the material and composite results, considered various practical conditions, to yield the primary configuration and dimensions of the treatment unit. The details of the steps involved in arriving at the suitable material selection and the numerical simulation are discussed in this paper.
