Description

The invention relates to a filter cartridge for filtering cleaning wastewater from turf and rubber granulate floors and a method for cleaning cleaning wastewater from turf and rubber granulate floors using this filter cartridge. Turf and rubber granulate surfaces are two different types of artificial sports surfaces commonly used in sports facilities, fitness centers, and playgrounds. Both offer advantages over natural grass surfaces, such as lower maintenance and improved weather resistance. Turf (also called artificial grass) is an artificial grass surface made of synthetic fibers that mimics natural grass. There are various types of turf, which can vary depending on their intended use. Turf surfaces are commonly used in soccer, hockey, rugby, and American football fields, as well as in golf courses and landscaping. The main components of turf surfaces are fibers, infill, and the substructure. The synthetic fibers form the blades of grass and are often made of materials such as polyethylene, polypropylene, or nylon. The fibers are designed to resemble natural grass blades while also being resistant to wear and tear. Between the artificial grass blades is an infill material, often made of sand, rubber, or a mixture of both. The infill provides stability, shock absorption, and plays a crucial role in the performance of the sports surface. Beneath the turf is an elastic layer that provides additional shock absorption and drainage. This layer can be made of various materials, such as rubber granules, foam, or a combination of both. Rubber granulate flooring is a sports surface made primarily from recycled rubber materials, such as old tires. These floors are commonly used in playgrounds, running tracks, and fitness areas. Rubber granulate flooring offers shock absorption and slip resistance, making it ideal for high-impact activities and slippery conditions. The main components of rubber granulate flooring are the rubber granulate and the binder. The base of these surfaces consists of small rubber particles, the rubber granulate, which is obtained from recycled tires or other rubber products. To hold the rubber granulate together and form a stable surface, a binder, often polyurethane-based, is used. Turf and rubber granulate surfaces can present several cleaning and maintenance challenges, particularly when materials from these surfaces enter the municipal sewer system. Some of the main issues are outlined below: When materials such as rubber and plastic particles or infill are eroded from these surfaces and enter the sewer system, they can cause pollution. These particles can enter rivers and streams and eventually reach the ocean, where they can degrade water quality and harm aquatic life. Microplastics, derived from synthetic fibers and rubber, are a growing environmental concern and can enter the food chain. Materials such as rubber granulate or sand and rubber infill from turf surfaces can enter the sewer system and cause blockages. These blockages can lead to costly repairs and maintenance, disrupting the proper functioning of the municipal sewer system. Cleaning turf and rubber granulate surfaces can be complicated and time-consuming. Containing and removing eroded material can be difficult, especially over large areas. Often, specialized equipment or personnel are required to effectively clean and maintain these surfaces. Some turf and rubber granulate floors can have limited water permeability, especially if poorly maintained or soiled. This can cause water to pool on the surface or enter the drainage system instead of naturally soaking into the ground. To minimize these problems, it is important to regularly maintain and clean turf and rubber granulate surfaces to reduce material loss. Using filters or collection systems near drainage openings can help trap particles before they enter the sewer system. Furthermore, operators of sports and leisure facilities should follow environmental regulations and best practices to reduce their impact on the environment and the sewer system. The use of filters to treat wastewater from turf and rubber granulate surfaces can help reduce pollution and blockages in wastewater systems. However, there are also some problems and challenges associated with the implementation and use of such filter systems. Here are some of the main problems: Selecting the right filter Selecting the right filter can be challenging, as it must be able to effectively remove various types and sizes of particles from the wastewater. This can require careful consideration of factors such as flow rate, particle size, and filter media. Filters used to treat wastewater from turf and rubber granulate surfaces require regular maintenance and cleaning to maintain their effectiveness. Removing and disposing of the trapped particles can be time-consuming and labor-intensive. Additionally, the filters may need to be replaced or cleaned periodically to prevent clogging or reduced performance. The purch
