Why Scrubber Pack Media Matters in Modern Water Treatment
In water and wastewater treatment systems, performance depends on far more than pumps, tanks, and controls. One of the most critical, yet often overlooked components is the treatment media inside the system.
Whether treating drinking water, removing odors, controlling emissions, reducing dissolved gases, or filtering contaminants, the correct scrubber pack media directly impacts efficiency, operational reliability, maintenance costs, and regulatory compliance.
Across industrial facilities, municipal treatment plants, food processing operations, semiconductor manufacturing, and environmental applications, engineered media solutions help treatment systems perform at their highest level.
At DeLoach Industries, advanced treatment systems are designed with carefully selected media configurations to maximize contaminant removal, airflow efficiency, hydraulic loading, and long-term durability.
Understanding Scrubber Pack Media
What Is Scrubber Pack Media?
Scrubber pack media refers to engineered materials installed inside treatment towers, filters, and scrubbers to improve contact between water, air, chemicals, or contaminants during the treatment process.
Depending on the application, the media may:
- Increase surface area for gas transfer
- Improve filtration efficiency
- Enhance contaminant absorption
- Promote biological growth
- Reduce pressure drop
- Improve chemical reaction efficiency
- Support airflow distribution
In packed tower systems, the media acts almost like a “traffic control system,” directing liquids and gases through engineered pathways that maximize interaction time and treatment effectiveness.
This principle is especially important in:
- Degasification towers
- Decarbonation systems
- Biological scrubbers
- Chemical scrubbers
- Carbon filters
- Pressure filters
- Air stripping systems
- Odor control systems

How Scrubber Pack Media Works
Maximizing Surface Contact
Most water and air treatment processes rely on mass transfer — the movement of contaminants from one phase to another.
For example:
- Dissolved gases move from water into air
- Odorous compounds move into chemical solutions
- Organic contaminants adsorb onto activated carbon
- Suspended solids become trapped in filtration media
The more surface area available, the more efficient the treatment process becomes.
That’s why modern random packing media and structured media designs are engineered to:
- Create turbulence
- Prevent channeling
- Improve flow distribution
- Increase contact time
- Reduce clogging
- Optimize hydraulic performance
In packed scrubber towers, contaminated air travels upward while liquid treatment solutions flow downward across the media bed. This counter-current flow dramatically improves contaminant removal efficiency.
Types of Media Used in Water and Wastewater Treatment
Random Packing Media
Random packing media, also called loose-fill media, is commonly used in:
- Degasification towers
- Air stripping systems
- Chemical scrubbers
- Biological odor control scrubbers
These media components are designed to maximize surface area while minimizing airflow resistance and pressure loss.
Common materials include:
- Polypropylene
- PVC
- CPVC
- Fiberglass-reinforced plastics (FRP)
- Ceramic materials
- Stainless steel
Typical applications include:
- Hydrogen sulfide (H2S) removal
- Carbon dioxide (CO2) removal
- Volatile organic compound (VOC) treatment
- Odor control
- Industrial air emissions
In degasification systems, water repeatedly reshapes and redistributes across the media surface. This continuous reforming of water droplets allows dissolved gases to escape efficiently.
This process is widely used after reverse osmosis treatment to remove corrosive gases and stabilize water chemistry.

Activated Carbon Media
Activated carbon media is one of the most widely recognized filtration media in both water and air treatment systems.
Its highly porous surface structure allows it to absorb contaminants like a sponge.
Carbon media removes:
- Chlorine
- VOCs
- Taste and odor compounds
- Organic chemicals
- Hydrogen sulfide
- Industrial contaminants
Over time, carbon media becomes saturated and must either:
- Be replaced
- Be thermally regenerated
- Undergo chemical regeneration depending on system design
Activated carbon systems are frequently used in:
- Municipal water treatment
- Food processing
- Semiconductor manufacturing
- Wastewater polishing systems
- Air emission control systems
Sand, Anthracite, and Multimedia Filter Media
Pressure filters and multimedia filters rely on layered granular media to remove suspended solids.
Typical media combinations include:
- Sand
- Gravel
- Anthracite coal
- Garnet
- Greensand
Each layer performs a specific filtration role based on particle size and density.
How Multimedia Filtration Works
Larger particles are trapped in the upper layers while finer contaminants move deeper into the media bed.
This staged filtration approach:
- Improves dirt-holding capacity
- Extends filter run times
- Enhances filtration efficiency
- Reduces downstream fouling
Multimedia filtration systems are commonly used for:
- Pretreatment before reverse osmosis
- Industrial process water
- Municipal drinking water
- Cooling tower filtration
- Wastewater reuse systems

The Role of Media in Odor Control Scrubbers
Why Media Selection Is Critical
Odor control systems depend heavily on media performance.
In chemical and biological scrubbers, the media must:
- Provide sufficient surface area
- Resist corrosion
- Support biological growth
- Maintain airflow efficiency
- Prevent excessive pressure drop
Improper media selection can lead to:
- Reduced contaminant removal
- Increased maintenance
- System fouling
- Scaling
- Media collapse
- Premature equipment failure
For example, hard makeup water can create mineral scaling within scrubber media beds, reducing airflow and treatment efficiency over time. Proper media selection and system design help minimize these operational issues.

Biological Scrubbers and Media Performance
Supporting Beneficial Bacteria
Biological odor control scrubbers use specially selected media to support bacterial colonies that consume contaminants.
These systems are commonly used for:
- Hydrogen sulfide removal
- VOC reduction
- Municipal wastewater odor control
- Food processing applications
The media acts as a habitat for bacteria while also maintaining:
- Moisture retention
- Airflow distribution
- Nutrient transfer
Common biological media characteristics include:
- High void space
- Corrosion resistance
- Large surface area
- Low pressure drop
When properly designed, biological scrubbers can reduce chemical consumption and lower operating costs compared to traditional chemical scrubbers.
