Colloide was the main contractor appointed by Sligo County Council to design and install a packaged wastewater secondary treatment plant.

The treatment plant was designed and built as a packaged plant in two parallel streams, each one comprising an aeration tank and MBR tank. The membrane filtration process used submerged membranes.

We designed, installed and commissioned a system comprising aeration tanks, MBR systems and a containerised control building including control panel, dosing systems, blowers, permeate pump and recirculation pumps.
