Pilot plants

Given the great variety of macromolecules that are part of the recalcitrant COD of an industrial wastewater stream, it is very often necessary to conduct a pilot test on the field to estimate the electrical costs associated with the chemical electro-oxidation reaction ( kWh / kgCOD removed) and the connected investment budget for the full-scale solution.

To carry out this phase, it is possible to adopt various solutions for pilot plants built to accomodate the customer’s needs. The simplest solution is represented by a pre-fabricated stand-alone unit built on a skid where the electro-oxidation module is dropped into a fiberglass tank and connected to the power generator placed externally and controlled by the electrical control panel. The wastewater to be treated is sent to the plant by means of an adjustable flow pump and is percolated from top to bottom of the pre-fabricated unit where it is collected and sent to drain by gravity through appropriate drainage pipes.

Because the electro-oxidation reaction generates volatile compounds such as CO₂ and O₂, the pilot will be equipped with a top cap and both natural and forced ventilation pipes capable of extracting the gases generated and removing them from within the system.

Main features:

• Perfectly transportable, mounted on skids or in containers
• Completely pre-assembled in workshops and can be placed outdoors
• Suitable for field tests of short or long term industrial waste
• Treatable flow rates that vary according to the characteristics of the wastewater from 0.5 to 4 m³/h
