Housing Filter Cartridge

Housing Cartridge Filter – How to Choose the Right Material for RO System, Oleochemical & Power Plant Applications

What Is a Housing Cartridge Filter?

A Housing Cartridge Filter is a protective vessel designed to hold cartridge filters during the filtration process. It ensures that fluids are properly directed through the filter elements under pressure while preventing any leakage or contamination.

In industrial applications such as Reverse Osmosis (RO) Systems, Oleochemical Plants, and Power Plants, the housing serves as a critical barrier — protecting the filtration core from chemical corrosion, high pressure, and extreme temperatures.

Without the right housing material, even the best cartridge filter can fail prematurely, leading to contamination, higher maintenance costs, and operational downtime.

How to Choose the Right Housing Cartridge Filter Material

Selecting the right housing material depends on your process conditions: chemical composition, temperature, pressure, and cleaning frequency.
Here’s a detailed guide for each application:

1. For RO System Pre-Filtration (SWRO & BWRO)

  • Recommended Materials:

    • FRP (Fiberglass Reinforced Plastic) – corrosion-resistant, lightweight, ideal for seawater and brackish water.

    • SS316L Stainless Steel – superior chemical and salt resistance, perfect for CIP (Cleaning in Place) systems.

  • Why:
    RO pre-filters handle saline water and operate at 4–8 bar pressure. FRP or SS316L housing ensures long lifespan and stable performance under harsh marine conditions.

  • Technical Tip:
    Use multi-cartridge housing (4–22 elements) to maintain high flow rates without significant pressure loss.

2. For Oleochemical Filtration

  • Recommended Materials:

    • SS304 or SS316L Stainless Steel.

    • Use SS316L for acidic or solvent-rich fluids.

  • Why:
    Oleochemical industries require hygienic, food-grade, and easy-to-clean materials. Stainless steel prevents contamination, maintains product purity, and supports CIP/SIP cleaning cycles.

  • Technical Tip:
    Choose sanitary clamp connection housings for faster maintenance and minimal downtime.

3. For Power Plant & Boiler Feed Applications

  • Recommended Materials:

    • Epoxy-Coated Carbon Steel – ideal for make-up or cooling water systems.

    • SS316L – best for demineralized or condensate polishing units.

  • Why:
    High-pressure, high-temperature environments demand durable and corrosion-resistant housings.

  • Technical Tip:
    Opt for vertical multi-cartridge filter housings with davit arm design for safe and efficient cartridge replacement.

FAQ About Housing Cartridge Filters

Q1: What’s the difference between SS304 and SS316L housing?
👉 SS316L contains molybdenum, offering superior corrosion resistance in marine and chemical applications.

Q2: Can FRP housings handle hot water?
👉 Yes, up to around 90°C. For higher temperatures, stainless steel is recommended.

Q3: What’s the typical working pressure?
👉 6–10 bar for PP & FRP housings, and up to 25 bar for SS316L types.

Q4: When should I use a multi-cartridge housing?
👉 When flow rate exceeds 10 m³/h or if longer filter lifespan is needed before cartridge replacement.

Q5: Can I order custom sizes?
👉 Absolutely! PFI Filtration provides customized housing designs for DOE, SOE 222, or SOE 226 filter cartridges.
