The recycling sector is the one dedicated to the recovery of material deriving from crushing processes and soil washing. The material has to be washed to remove the polluting part, decontaminating it.
The system works with attrition cells, special tanks where the sand is agitated to eliminate contaminants through attrition, then the material is filtrated by the filter press. An important application is for the recovery of construction materials.
Plastics are inexpensive, lightweight and durable materials, which can readily be moulded into a variety of products that find use in a wide range of applications. As a consequence, the production of plastics has increased markedly over the last 60 years.
Recycling is one of the most important actions currently available to reduce these impacts and represents one of the most dynamic areas in the plastics industry today. Recycling provides opportunities to reduce oil usage, carbon dioxide emissions and the quantities of waste requiring disposal.
Batch filter presses are known industry wide for their thoroughness in dewatering wastewater with high solids content. Unlike funnel, vacuum, and belt filter presses, these are designed to apply high pressure directly to the slurry in between the press plates, expelling nearly every bit of liquid. What remains is a solid, compact, sludge cake ready for the landfill, and water that’s fit for reuse or expulsion into the sewer after filtering. A batch filter press is ideal for industries like plastics recycling.
