Bag Filtration


...

Bag filters tend to have the lowest equipment investment costs, and are generally tolerant of a wide range of process conditions, making them a good choice for a wide range of applications.

Careful consideration, when choosing a liquid filtration system, will offer numerous potential benefits. A wise filter selection can minimize process downtime, reduce or eliminate waste disposal costs, limit worker exposure to the process liquid, reduce maintenance time and expense, and improve product quality.

The various ECOLINE, SIDELINE, FLOWLINE and MAXILINE bag filter vessels are fitted with different bag hold-down rings (included with vessel). They hold the filter bag in the restrainer basket fitted in the filter vessel.

...

During filtration, they float in the filter bag, minimizing the amount of residual liquid present in the filter bag and reducing product loss. This eases the changing of the filter bags and eliminates the need for expensive pressure-aided draining systems. The 316 SS balloons’ maximum ³P is 230 psi and they are available in sizes #01 and #02.

...

Heavy duty 316 SS baskets (included with housing) allow use of filter bags up to differential pressures of 75 psi. Available in all standard bag sizes, fitting all Eaton bag filter vessels. Specially designed restrainer baskets are available for specific applications, including special materials of construction such as Hastelloy or Halar coated, perforated plate, gasketed basket top ring, conical shape, etc.

...

Recommended for safe positioning of the filter bag in order to eliminate up and down movement of the bag caused by uncontrolled changes in pressure drop, thus avoiding the chance of the bag bursting. During filtration the bag holder remains in the filter bag (also in combination with the displacement balloon). Bag positioners are available in sizes #01, #02 and #05.
