Iron depositing, Zwolle, Holland

The project:


Deposition of iron using a submersible aerator in Zwolle, Holland


Executing company:

Distrimex Pompen&Service BV


The problem:


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.


Our solution:


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.

U slučaju abrazivnih i korozivnih primjena, normalno je da će se u određenim komponentama dogoditi snažnije trošenje. S obzirom na gornju primjenu trošenje se može odvijati uglavnom u radnom kolu, miješalici, usisnoj ploči, rukavcu osovine, uljnom prstenu, mehaničkoj brtvi, kućištu pumpe, cjedilu, kućištu motora i ispusnoj spojki. Ovisno o radnim uvjetima vijek trajanja tih dijelova može značajno varirati i može biti kraći od pravnog zakonskog razdoblja.
