Manufacturers, Exporters, Suppliers of Filter Media in Bhutan

Innovacorp India Pvt Ltd is a manufacturer, exporter, and supplier of filter media for sugar processing in Bhutan. Our range covers silica sand, anthracite, garnet, activated carbon and iron removal media for juice clarification, syrup decolourisation and process water treatment. Filtration in a sugar mill is not a single step — it runs from the juice clarifier to the syrup filter to the water treatment plant, and each stage has its own media requirement. The right media starts with the filter design and the target water or juice quality, not a fixed specification.

Why Filter Media Matters in Sugar Processing

Filtration is the stage where suspended solids, colloidal matter and colour bodies are physically removed from the process stream. In juice clarification, the filter captures fine particles that carry sucrose into the mud. In syrup decolourisation, activated carbon adsorbs colour bodies that would otherwise carry through to the crystal. In process water treatment, sand and anthracite remove turbidity before the water reaches the boiler or the cooling tower. The media's physical properties — grain size, uniformity, hardness, density — decide how long the filter run lasts, how much water is used in backwash, and what quality of filtrate comes out.

Where It Is Used

• Juice clarification: Silica sand and support gravel in pressure filters and rotary vacuum filters.
• Syrup decolourisation: Activated carbon for colour body adsorption.
• Process water treatment: Dual media filters (anthracite + sand) and multi-grade filters (MGF) for turbidity removal.
• Iron removal: Catalytic media for process water where dissolved iron is present.
• Effluent treatment: Sand and anthracite in ETP polishing filters.

Types We Manufacture, Export & Supply in Bhutan

• Silica sand: Washed and graded for pressure filters and rapid gravity filters; effective size and uniformity coefficient matched to the filter design.
• Support gravel: Graded gravel layers for filter bottoms, to support the sand bed and prevent media loss during backwash.
• Anthracite: For dual media and multi-media filters; lower density than sand, so it forms the top layer and captures coarser particles.
• Garnet: High-density media for multi-media filters where a finer bottom layer is needed.
• Activated carbon: Granular activated carbon (GAC) for syrup decolourisation and process water treatment; grade selected according to the colour load and the contact time.
• Iron removal media: Catalytic media for dissolved iron and manganese removal from process water.

Specification Table

Because filter media cover a wide product range, the table below gives indicative ranges. Actual specification and grading are confirmed per product against the datasheet and the filter design.

Property	Typical Range
Media type	Silica sand, anthracite, garnet, GAC, iron removal media
Effective size (ES)	0.4 – 1.2 mm (product and application dependent)
Uniformity coefficient (UC)	1.3 – 1.7 (graded media)
Bulk density	0.7 – 1.7 g/cm³ (media dependent)
Hardness (Mohs)	6 – 7 for silica sand; 3 – 4 for anthracite
Acid solubility	≤ 5% (silica sand, acid-washed grades)
Packing	25 kg / 50 kg HDPE bags; 1,000 kg jumbo bags
Storage	Dry, covered area; protect from contamination

Final specification and grading are confirmed against the product datasheet and the filter design.

Application and Dosage

Media loading depends on the filter type, bed depth, flow rate and the target filtrate quality. Indicative ranges:

• Pressure sand filter: Bed depth 600 – 1,200 mm; media loading 600 – 1,200 kg/m² of filter area.
• Dual media filter (anthracite + sand): Anthracite layer 300 – 600 mm, sand layer 300 – 600 mm; loading confirmed against the filter design.
• Multi-grade filter (MGF): Garnet + sand + anthracite layers, each 150 – 300 mm; loading confirmed against the design.
• Activated carbon filter: Bed depth 600 – 1,500 mm; contact time and loading confirmed against the colour load.
• Iron removal filter: Bed depth 600 – 1,200 mm; loading confirmed against the iron concentration in the water.

Media loading, backwash rate and support gravel grading are discussed with your design or plant engineers. Final specification is confirmed against the filter design and a trial on the filter.

Packing

• 25 kg / 50 kg HDPE bags (sand, anthracite, garnet, GAC)
• 1,000 kg jumbo bags for large media fills
• Bulk bags or tanker loads for very large projects

Key Benefits

• Media graded to match the filter design — effective size and uniformity coefficient specified per application.
• Available in sand, anthracite, garnet, GAC and iron removal media for different stages of sugar processing.
• Uniform grain distribution helps prevent channeling and supports even pressure across the filter bed.
• Backwash guidance is provided with each media type, to help maintain filter performance over time.
• Product datasheets and grading certificates are provided for design and procurement records.

Technical Support

Filter media work only when they match the filter design and the process stream. We work with your design or plant engineers on media selection, bed depth, loading calculation, support gravel grading and backwash review. Final specification and grading are confirmed against the datasheet and the filter design.
