Rain Power Filtration
Pressure Vessels for Every Drop of Flow
Filtration Vessels (SS / MS / FRP)
Rain Power Filtration manufactures high-quality pressure vessels for water and wastewater filtration systems. Available in SS, MS, and FRP construction, with options for internal FRP lining, rubber lining, epoxy coating or unlined (bare metal). These vessels are used in sand filters, carbon filters, softeners, iron removers, and pre-treatment systems in industrial and commercial plants.

Material of Construction (MOC)
| Type | Description |
|---|---|
| SS 304 / SS 316 | Corrosion resistant, hygienic, used in RO, food, pharma, and high-purity applications |
| MS (Bare) | Heavy-duty for industrial applications – painted externally, used for raw water/ETP |
| MS + FRP Lining | Internally FRP coated for chemical resistance with MS structure |
| MS + Rubber Lining | For acid/alkali/effluent use where mechanical and chemical resistance is required |
| FRP | Lightweight, corrosion-resistant, ideal for medium pressure and compact systems |
Working Process
- Water enters through the inlet nozzle at top or side.
- Passes through the filter bed (sand, carbon, resin, etc.).
- Filtration media retains turbidity, TSS, odor, chlorine, or hardness based on system use.
- Filtered water exits via the underdrain and outlet nozzle.
- Periodically, a backwash cycle (manual or automatic) reverses flow to clean the media.
Applications
- Sand, Carbon, Dual Media Filtration Units
- Softeners, Iron Removers, DM Pretreatment
- RO Plant Pretreatment Skids
- STP, ETP, and ZLD Plant Clarification & Recovery
- Portable & Containerized Treatment Plants
- Industrial and Utility Water Systems
