Deposition of iron using a submersible aerator in Zwolle, Holland
Distrimex Pompen&Service BV
The groundwater is highly impure with dissolved iron. Clarification using oxidation and filtration of iron oxide using a water softener system. Then filtration through a sand filter and finally an activated carbon element.
Oxidation carried out by installing a Tsurumi model 32TRN21.5 submersible aerator. The use of a submersible aerator already causes the greater part of the iron to oxidize and precipitate, so that it remains in the sand filter. The rest of the system is less contaminated, requiring fewer replacement of the expensive carbon filter. The result is that maintenance and operating costs are minimized.
