The PlaWas network works on a multitude of projects in different states:

MikroSep – Elimination of microplastics from rainwater runoff in road space (tire abrasion)

A decentralised filter system for surface drainage systems on roads is being developed that will be able to collect the microparticles of tire abrasion. To avoid overloading the system, the first flush, which contains over 80% of the suspended surface dirt, will be filtered during heavy rainfall. The filter inserts are designed as a retrofit system to be installed in as many existing sewage systems as possible

Status: ZIM funding granted

Project duration: 01.07.2019 to 30.06.2021

MikroGrau – Purification of the wastewater stream of washing machine waste water for use in the grey water system

The filter system for the use of washing machine waste water in the greywater system is designed to remove the solid load from the water flow and at the same time collect it so that the dirt load is not disposed of via the general waste water disposal system as in conventional greywater systems, but is completely removed from the waste water flow and disposed of via the solid waste disposal system.

Status: ZIM funding granted

Project duration: 01.11.2019 to 30.04.2022

MicroWash – Flotation of microfibres from industrial laundry

The waste water stream of industrial laundry contains a large number of fibres, most of which are fed into the municipal waste water treatment plants via the waste water systems. Those plants are not designed to eliminate microparticles.

The innovative flotation system is designed to extract and separate the microfibres in the wastewater stream of the industrial laundry in a continuous process using bubble technology. The flotation system will be continuously immersed under water, which places special demands on the drive and media supply. The wastewater processes of the laundries have to be adapted. In order to enable a quick installation, the flotation system will be integrated into a process kit that can be installed as an “easy-to-fit” solution for the integration of well-known laundry systems.
