How side stream filters improve water filtration performance in buildings

Posted on

Closed-loop water systems, integrated into a building's environmental control infrastructure, are vulnerable to contamination from suspended particles. This can lead to inefficient temperature regulation and reduced system performance. Side stream filters serve a crucial yet often unnoticed role in maintaining the cleanliness and efficiency of these systems.

What is a Side Stream Filter?

A side stream filter is designed to remove contaminants from a closed-loop water system within a building. These filters are typically installed inside the plant room and are referred to as "side stream" because they only process a portion of the total flow at any given time, rather than the entire system volume. This method ensures continuous filtration without disrupting the main system operation.

Side stream filters generally handle 5-15% of the full system flow, allowing the entire system volume to be filtered two to three times per day. This approach ensures consistent water quality while minimizing energy and operational costs.

We typically recommend a cartridge-based side stream filter system due to its high efficiency and ease of maintenance. However, other technologies like hydro-cyclones or separators may be used for removing larger debris. While these alternatives can be effective, they usually lack the fine filtration capabilities of cartridge filters. A standard setup from Amazon Filters might include a Stainless Steel 61 Series filter housing equipped with disposable Amazon SupaSpun II cartridges.

We prefer absolute-rated filters over nominal ones because they maintain their contaminant removal efficiency throughout the filter’s lifespan, even when water quality fluctuates. In contrast, nominal filters tend to lose effectiveness over time or may release previously captured particles, leading to unexpected fouling and system issues.

In addition to improving water quality, a side stream filtration system can also:

  • Reduce wear on critical components by removing suspended solids
  • Minimize biological fouling and lower the need for chemical treatments
  • Help eliminate trapped air in the system
  • Save time and labor compared to traditional flushing methods
  • Improve overall system cleanliness
  • Decrease maintenance requirements, equipment downtime, and repair expenses

By investing in a reliable side stream filtration system, building operators can ensure smoother operations, reduce long-term costs, and extend the life of their HVAC and plumbing systems. For more information on how to optimize your water filtration strategy, check out our guide today.

Square Hole Perforated Metal

Square hole perforated metal is a type of metal Perforated Sheet or Filter Mesh that has been punched with square-shaped holes. This material is often used in architectural applications, industrial applications, and decorative purposes due to its unique properties.
Properties:
1. Permeability: Square hole perforated metal allows air and light to pass through while blocking solid objects.
2. Strength: The metal's strength is not compromised significantly by the perforations, making it suitable for structural applications.
3. Corrosion Resistance: Depending on the type of metal used (e.g., stainless steel, aluminum), it can offer excellent corrosion resistance.
4. Versatility: It can be used in various environments, including outdoor conditions due to its durability.
5. Aesthetic Appeal: The perforated pattern can create interesting visual effects when used in façades, fences, or screens.
Applications:
- Architectural: Used in facades, sun shading systems, ceiling panels, and decorative elements.
- Industrial: In ventilation systems, filters, and acoustic barriers.
- Decorative: For artistic installations, interior design elements, and partitions.
- Safety: In grilles and security barriers where visibility is required but tampering is not desired.
Choosing the Right Type:
The selection of square hole perforated metal depends on several factors:
- Material: Stainless steel, aluminum, copper, etc., each offering different strengths and corrosion resistance.
- Size of Holes: Determines the amount of light and air that can pass through, as well as the overall appearance.
- Gauge/Thickness: Affects the strength and flexibility of the material.
- Pattern: The arrangement of holes can vary, affecting the final product's appearance and functionality.
Installation and Maintenance:
Square hole perforated metal requires proper installation to ensure safety and effectiveness. Regular cleaning is necessary to maintain its appearance and functionality, especially in outdoor settings. Corrosion-resistant coatings may be applied to prolong the life of the material.
