Tertiary Treatment – Disc Filters (10–100 Microns)

Microfiltration is a stage of water or treated wastewater conditioning in which fine suspended solids, fibres, organic and mineral particles are removed in order to achieve very low turbidity and total suspended solids parameters. Such units are applied as final filtration (tertiary treatment) before discharge of water to the receiving body or prior to further processes (e.g. ultrafiltration, reverse osmosis).

1.   Filtration Ranges 5–200 µm

• Polishing of wastewater after secondary clarifiers – filters 5–10 µm.
• Wastewater treatment prior to ultrafiltration and reverse osmosis – filters 100–200 µm.

2.   Applications

• Polishing of treated wastewater in municipal wastewater treatment plants prior to discharge into sensitive surface waters.
• Protection of UF/RO membranes against excessive suspended solids loading.
• Treatment of process water in the food, paper and energy industries.
• Irrigation systems (protection of drippers and sprinklers against clogging).

We ensure that maintenance and servicing requirements are minimised, while the equipment is characterised by high durability and reliable operation. This on the one hand significantly reduces operating costs, and on the other increases performance and operational efficiency of the units.

As part of the process of selecting equipment or complete technological lines, we provide an analysis of the actual and forecasted conditions at the facility as well as preparation of the technological design.
