Industrial filtration is crucial for the chemical sector, as it helps to guarantee the quality and purity of end products. The filtration process is used to remove unwanted solid particles from chemical products, ensuring that they meet quality standards and are safe to use.

How can hermetic candle filters (HBT) help the chemical industry?

Hermetic candle filters are extremely useful for the chemical industry. These filters are highly efficient at separating liquids from solids and can operate under a wide range of pressure and temperature conditions. In addition, the hermetic nature of these filters allows for adequate control over the process environment, minimizing the risk of cross-contamination and increasing operational safety.


How do Hollbras HBT vertical candle filters work?

HBT candle filters perform solid-liquid separation, a crucial process in the chemical industry. The filtration process begins with the formation of a pre-coat, either with the solid to be filtered or with a filtration aid. Once the pre-coat is formed, the liquid to be filtered is pumped into the filter, where the internal pressure pushes it through the filtration candles. The solid particles are retained on the surface of the candles lined with the filter fabrics. The filtration process is terminated when the filter reaches its solid limit. The retained solids can be discharged dry, by drying the solids and cleaning the filtration candles by blowing inert gas air against the flow; or wet, by washing the filter elements also against the flow using water or solvents suitable for the process. This filtration process can be completely automated.
