Industrial Filters

Sailent Features

• Batch Type
• Skid Mounted
• Zero Hold Up
• Fast and Easy Removal
• Easy Removal of Cake
• C-Gmp Model
• Crystal Clear Filtrate Filtration Upto 1 Micron Possible
• Hot Filtration Possible

Application

• Bulk Drug
• Formulation
• Fine Chemical

Construction

• Horizontal filter press, Filter cartridge assembly made of no. of disc Type Filter plates perforated filter screens, filter media, Inter locking cups with pump & piping, mounted on trolley

Working Principle

• Liquid to be filtered is pumped into the filter shell and through opening on side of plates. Filters media(paper/ fabric) retains impurities allows crystal clear filtrate to flow through central channel formed by interlocking cups & to outlet of filter.

Rotary Vacuum Drum Filter

Salient features:

• Continuous Filter
• Very high filtration rate due to renewed filtration surface after every rotation
• Low maintenance due to very low speed
• Operation from control panel
• Ideal for fine, gelatinous & Slurry Solids
• Efficient & Uniform spray washing of cake
• Variable speed operation, No human contact
• Quick Product changeover, due to faster & easier cleaning.

Application

·         Effluent Treatment Plant (ETP)

·         Chemicals (Slurry)

Material of Construction

• Carbon Steel
• Stainless Steel
• Ms/ Rubber / PP- FRP Lined

 Application

• Best Suitable for Slurries to 20% to 40% Soild (w/w)
• Cake can be washed satisfactorily
• Oscillating agitator provided to keep the solid in suspension

Limiting Factor

• Not suitable for slurries with solvent
• Cannot be used for slurries with high temperature

 Agitated Nutsche Filter

Salient Features

• Closed batch types operation
• Repeated & effiecient wash with reslurrying.
• Vacuum or pressure filtration
• Operation from Control panel
• No toxic fumes in operating area
• Very high Solvent recovery
• Minimum Labour required
• Drying of wet cake under Vacuum

Application

• Pharmaceuticals
• Pesticides
• Organics/ Inorganic Chemicals

Material of Construction

• Carbon Steel
• Stainless Steel
• MS Rubberlined
• Hastelloy

Filtering Operation :

• Slurry is charges to gravity or pump vacuum is applied in bottle section through filte receiver
• Filtrate is collected through the filter bed & collected in Receiver, located below the lower compartment of filter & cake layer begin to form slowly on filter plate.
• After 1st filtration is over, cake shall have almost 10 to 30% moisture
• After 1st stage filtration , wet cake can be reslurried & spray washed by rotation agitator in clockwise & anticlockwise direction with up & down movement of agitator.
• Cake is further pressed & Squeezed by rotating agitator in up & down motion to minimize liquid content in wet cake. Cake is discharged through Discharge nozzle by rotating agitator in reverse direction.

Drying Operation

• For maximum recovery of liquid & drying vacuum is applied on top chamber & cake is heated by applying hot water / steam to form solvent vapour, which is turn is condensed in the condesor & collected in receiver.
• Cake is finally discharged automatically by vertical & reverse rotary movement of agitator.

Salient Features :-

• Continuous Operation Horizontal / Vertical Type.

• Higher Filtration area per unit volume.

• Faster filtration.

• Vacuum / pressure filtration.

• Automatic cake discharge.

• Close operation.

• No Filter cloth / Filter Aid

• Saves Labor and time

• Less space requirement
