Filtration and Savings with the GAW ECO-R filter

Did you know how paper and board makers get rid of agglomerates and contaminants from fluids, dispersions, coating pigments and colours? 

Filters and sieves are indispensable components in the highly complex process of paper manufacturing and finishing. But in times of rising prices for energy and raw material they are also an important factor to save costs.

The ECO-R filter from GAW is a powerful example of how a medium can be filtered in a sustainable and economical way: the filtered medium is conveyed through the upper intake, through the sieve blades of the strainer basket, to the outlet at the bottom of the filter. The coarse particles stick to the outside of the strainer basket.

The strainer basket is designed as a slotted mesh insert or lasered perforated basket. Thanks to the built-in displacement body, very high flow velocities as well as a low volume at large screen areas can be achieved at the same time. Depending on the dimensions and field of application, the ECO-R filter is equipped with a varying number of blades or brushes made of carbon or metal. The agglomerates and contaminants that adhere to the sieve basket are cleaned by the blades or brushes, conveyed to the filter bottom and introduced into the reject space. Optionally, the reject space can be designed as a lock, whereby the discharge of the agglomerates and impurities during continuous operation is possible.

Advantages include

• almost no loss of medium during reject and rinsing
• little downtime due to a high degree of automation
• fast scraper exchange
