Pressure Vessels & Filters
Robust Housing Solutions for Filtration, Softeners, and Ion Exchange Units
Pressure vessels are engineered containers designed to hold and manage pressurized liquids or gases — primarily water — during various stages of industrial treatment. In water treatment, they serve as housings for media such as sand, activated carbon, softening resin, or ion-exchange resin. These vessels ensure water flows evenly through the media under controlled pressure, enabling consistent filtration and treatment.
Applications
- Pretreatment Units: Sand, gravel, and multimedia filters
- Post-treatment: Activated carbon filtration, polishing filters
- Softeners: Hardness removal using ion exchange resins
- Demineralization Units: Cation and anion resin-based processes
- Reverse Osmosis Protection: SDI and turbidity control
- Effluent & Sewage Treatment: Organic and suspended solids removal
Types of Pressure Filters Based on Media & Function
| Filter Type | Media Used | Purpose |
|---|---|---|
| Multimedia Filter (MMF) | Sand, gravel, anthracite | Suspended solids & turbidity removal |
| Activated Carbon Filter (ACF) | Coconut shell carbon | Chlorine, odor, organic compound removal |
| Softener Vessel | Cation resin (Na⁺ cycle) | Hardness removal |
| Iron Removal Filter (IRF) | Manganese dioxide, Birm | Fe & Mn removal |
| Bag/Micron Filters | PP cartridges or mesh bags | Fine filtration (5–100 micron) |
Construction Materials & Grades
| Material | Suitable For | Notes |
|---|---|---|
| FRP (Fiber-Reinforced Plastic) | Domestic & Industrial RO, DM Plants | Corrosion-resistant, lightweight |
| Mild Steel (MS) | Large industrial plants | Requires epoxy coating inside |
| MSRL (MS Rubber Lined) | Acidic/alkaline chemical flows | Rubber protects against corrosion |
| Stainless Steel (SS 304/316) | Food, pharma, high purity applications | High durability, CIP compatible |
