Treatment plant designed for the remediation of groundwater contaminated by iron, boron and hydrocarbons, installed at an industrial site in an urban area.
Technology used
The system is made up of two parallel batteries of filters, each consisting of a deferrisation filter, an activated charcoal filter and a special ionic resin selective for boron.
Raw water is stored and placed in contact with an oxidising agent and pH corrector before being sent for filtration. Backwash water from the deferrisation filters is collected to precipitate metals and sedimentable solids. The deposited sludge is conditioned with polyelectrolyte and sent to a dehydration station. The treated water is returned to the groundwater.
The system is fully automated and managed by one of the most advanced versions of Pura XD software. In fact, the control centre also deals with the regeneration process of ion exchange resins.
The system provides for the remote acquisition and transmission of many analogue and digital signals (flow rates, pressures, differential pressures, pH measurements, level measurements).
There is the option of remotely controlling the system via an internet connection and the sending of alerts via SMS.
