Ion BOREAS Compact Ion-Exchange Fiber-Bed Scrubber

Ion-exchange scrubber captures various dusts 0.1 µm in size or larger.
In order to capture smaller elements, we recommend various supplements, such as caustic soda etc. The supplements are selected on a case-by case basis depending on the air and gas mixture in the client's operation environment.

Contaminated air enters the scrubber via a gas inlet flange. The contamination settles on a special ion-exchange cassette consisting of non-woven material. The cassette has a sponge structure which provides a basis to retain dust and other substances.

The dry scrubber is suitable if there isn’t too much contamination. If there is a lot of it, we recommend installing a wet scrubber. What sets a wet scrubber apart from a dry scrubber is that the cassette is sprayed with liquid designed to additionally neutralize harmful impurities, dust, and clean the cassette of contamination.

The Specifications depend on the package elements. For each client, we create a project based on a detailed survey about the production site and the nature of the dust and contaminations.
Each filter can optionally be designed in a non-standard execution, depending on the technical task of the client.

There can be more modules depending on the client’s technical task

We always compromise with the client and are willing to add the necessary functions range as well as other characteristics and parameters to the standard package.

A modification is a filter variation with a different quantity of modules. Adding modules entails a change in general performance, filtered air volume, size, and other technical specifications .

The ion-exchange scrubber consists of one or multiple modules.

The recommended performance of a single module is no more than 23500 cfm. In order to increase the performance, it is required to install additional modules (see example in drawing below).

A filter can optionally be designed with non-typical size depending on the client’s technical task.

The scrubber captures sprays and hard particles on a filtration cassette with a partial liquid fraction flow via the draining pipe.

The “Ion BOREAS Compact” frame is rectangular with flanges for connecting to the gas pipe section. Located inside is a filtration cartridge out of a needle-punched material. A cartridge in the form of a wire frame with vertical pockets increases the filtration area. The filtration material is held by a pressure frame. The cartridge is placed into the frame via the upper installation hatch into specially shaped guiding grooves for simple and easy installation. The hatch hermetically closes with a roof and padding. Placed in the internal part of the frame are drain pipes (modification 1) or a hydrogate (modification 2 and 3) to collect and divert liquid sludge and perform regeneration.

The filter frame has gas inlet and outlet chambers which allows duct filters to be installed of any configuration. The gas inlet chamber reduces the velocity of gases for more efficient cleaning. Located in the filter are viewing/maintenance hatches for convenient cassette regeneration.

Regeneration (washing) of the filtration material is performed to achieve a pressure differential of 700 Pa. If no pressure control is implemented, washing once a day for 15-30 days is required. Cassette washing is performed inside the frame with the help of an installed atomizer diverting washing water via a hydrogate or removing the cassette from the frame and washing it in special baths. The washing water volume is 2.5-5.5 gal per ft² of filtration material.
