USE

Hydropneumatic mixers, dynamic (with rings filling) are used for treated water aerating in order to facilitate precipitation of iron compounds. The mixers are neccesary element of water treatment system. They are to be used in individual collaboration with a filter (e.g. an iron remover) in cold water systems at maximum permissible pressure PS=6bar and max/min permissible temperature TS=6°C up to 20°C.
In relation to traditional cascade mixers they have big productivity at small building surface (shorter holding time required). The mean holding time for ARDW mixers is about 25-30 s. They are most often used when the building surface possibilities are limited. The flange connection which is used on the jacket makes them easy-to-operate and exploit - especially when cleaning and maintenance is concerned.


MIXER CONSTRUCTION

All the basic mixer elements (jacket, dished heads, connectors, etc) are made of low-carbon steel. The screens which separate the mixing space of water with air from the so called holding space are made of stainless steel. The construction allows to run the full internal revision thanks to the flange connection on the tank's jacket. In order to obtain the high degree of intermixing water with air the dynamic mixers are filled with Białecki rings (dashed surface on the mixer draft).

Mixer is protected against to corrosion by painting: internaly with polyester resins with PZH certificate for contact with drinking water, externaly with universal temporal protective paint. Manufacturer allows using other internal varnish sets (eg. epoxy resins) and executions with external surface painting (eg. set of polyurethan paints) for client's special wishes.

The manufacturer can also offer devices with other anticorrosion protections e.g. by:

  • hot galvanizing, two-sided
  • ebonit lining (rubbering)

We also offer hydropneumatic mixers made of austenitic steel.

The manufacturer allows any constructional changes of a filter in the range of placing any connectors diameters.
