Monitoring systems help landfill operators manage leachate levels

摘要

System Devices UK provides automation systems and support to customers in the United Kingdom and Ireland. The company's expertise covers automation and monitoring systems, SCADA and robotics. In recent years, the company has provided control systems to landfill operators that not only meet their immediate needs, but are so flexible, they allow for future expansion without having to change hardware or software later in the system's life cycle. Currently, the vast majority of municipal waste in the UK (over 85 per cent) is sent to landfills. Local governments across the UK provide land for the establishment of landfills and the disposal of household and other types of waste. But these sites don't remain landfills forever. Typically, landfills operate for 15 years, after which the site must be returned in good condition. This requires the collection, treatment, and discharge of leachate, which is created when moisture and rain water permeate the waste deposited in a landfill. As this water mixes within the solid waste, it picks up contaminates (organic and inorganic chemicals, metals, biological wastes) and becomes leachate.
