Fine filtration for algae, silt, and micro-particulate control.
The BWB (Basket with Bag Filter) is a specialty filtration unit combining a rigid metal basket and replaceable bag insert. It provides fine filtration beyond screen intake capabilities and is ideal for algae, silt, and micro-particulate control in irrigation and process water applications.
Filter bags available in 1-200 micron range for targeted filtration. Change micron rating anytime to match water quality and application needs.
Rigid basket supports bag and prevents collapse under pressure. Quick removal for bag replacement—no tools required, minimal downtime.
Flanged top lid with swing-bolt clamps for fast access. Open, replace bag, close—typical service time 5-10 minutes.
Provides filtration beyond coarse intake screens. Ideal for algae, silt, and micro-particulates that escape primary filtration.
Select micron rating based on your specific filtration needs—from coarse algae removal to fine silt capture.
Rigid metal basket prevents bag collapse under pressure and lifts out for quick bag replacement.
No tools required—open clamps, lift lid, replace bag. Typical service time 5-10 minutes.
Monitor differential pressure to determine optimal bag replacement timing. Drain valve for easy servicing.
Standard piping configurations make BWB filters easy to install in existing systems.
Construction: Mild steel with epoxy coating or 304/316 stainless steel options. Filter bags: polypropylene felt or nylon mesh (food-safe, chemically compatible). Seals: EPDM or Viton. Maximum operating pressure: 150 PSI (typical). Contact engineering for material selection guidance based on your water chemistry and application.
Specifications represent typical configurations. Contact engineering for detailed specifications based on your flow and application requirements.
| Model | Connection | Flow Range (GPM) | Basket Dia (in) | Basket Length (in) | Max Pressure (psi) | Bag Micron Range |
|---|---|---|---|---|---|---|
| BWB-04 | 4" FLG | — | 8 | 24 | 150 | 1–200 |
| BWB-06 | 6" FLG | — | 10 | 30 | 150 | 1–200 |
| BWB-08 | 8" FLG | — | 12 | 36 | 150 | 1–200 |
Note: Flow ranges vary significantly based on micron rating, water quality, and acceptable pressure drop. Coarse bags (100-200 micron) handle higher flows, fine bags (1-10 micron) require lower velocities. Contact engineering for application-specific flow calculations and bag selection recommendations based on your water analysis.
| Part | Description | Material |
|---|---|---|
| Basket | Support basket assembly | Epoxy-coated steel / SS |
| Bag | Filter bag | Poly felt / nylon mesh |
| Seal Kit | O-rings & gaskets | EPDM / Viton |
Filter Bags: Available in multiple micron ratings (1, 5, 10, 25, 50, 100, 150, 200) and materials (polypropylene felt, nylon mesh, specialty fabrics). Stock standard micron ratings for your application. Bags are typically disposable but some specialty fabrics are washable and reusable. Contact your dealer or CTC filtration specialists for bag availability, pricing, and recommended stocking quantities.
Use Together: Water Box upstream for coarse screening, BWB downstream for fine polishing—complete staged filtration from intake to emitters.
| Mesh | Open Area (%) | Equivalent Perf | Typical Use |
|---|---|---|---|
| 30 | 50 | 0.020–0.025 | Intake |
| 60 | 31 | 0.015–0.020 | Micro |
| 80 | 31 | 0.010–0.012 | Drip |
| 120 | 31 | 0.008–0.010 | Fine protection |
For coarse intake screening with large screen area, consider Water Box filters. Float-valved level control for consistent flow from ponds and canals.
Add BIG inline filters for pressure filtration. BWB handles fine polishing, BIG provides automatic cleaning and modular capacity.
Compact true-inline TIG filters for space-constrained installations. Works downstream of BWB for additional polishing stages.
Our filtration specialist team will help you select the right BWB model, recommend optimal bag micron ratings, and design a complete staged filtration system for your water quality and flow requirements.
