WaterWeave offers a sustainable and long term solution for purification of stormwater from heavy metal ions. The technology consists of a textile covered with a biomass which, when in contact with water, attract metal ions. By using the textile for water purification, it is possible to create a flexible and cost effective solution.
Stormwater, which is another word for the rainwater that is falling on hard areas such as roads, has high levels of heavy metal ions which constitutes a health risk for humans and other living beings. WaterWeave is developing a purification system for stormwater and wants to be part of the solution for creating a sustainable and good water environment.
WaterWeave’s textile water purification system makes it possible to absorb and capture heavy metal ions in stormwater as early as in stormwater sewers and ponds. Entering early in the water treatment chain is important in order to get a large-scale effect when purifying stormwater. This means that the use of WaterWeave’s water purification system makes it possible for municipalities and industries to control the emissions of heavy metals. WaterWeave’s technology for water purification will reduce the emissions of heavy metals in stormwater by up to 80 %.
WaterWeave’s system consist of a textile coated with biomass which, in contrast to traditional filters, does not require that the water is filtered through the textile. Instead, it is sufficient that the water gets in contact with the active surface binding the heavy metal ions. In this way, WaterWeave’s new technology provide efficient purification of large quantities of still water.
The use of textile for water purification has many advantages since it is flexible and easy to handle. Using textile makes it possible to customize a solution according to the customers’ needs, with relatively small means. Purifying water with textile also makes WaterWeave’s technology a cost effective solution, since it can easily be up-scaled. WaterWeave’s water purification system consists of simple and cheap materials that are already on the market, as well as a biomass that is cost-effective to produce. Also, the use of textile makes it possible to create a mobile solution that easily can be moved between sites, depending on use. A porous material such as textile means that the system has a large reactive contact surface, which is important for efficient absorption of heavy metals.
Initially, WaterWeave will focus on customized products where each product is customized according to each specific location and the customer’s needs. This approach is used in order to get an in depth understanding for the customers´ problem and the demands from the market. However, in a two years perspective WaterWeave aims at selling the product by meter in order to make it possible for the customers and retailers to create their own products from the material.
