MicroFlo®
Pool Filtration Systems
Filtration directly impacts water clarity, operating costs, maintenance time, and long-term facility performance. In commercial aquatic facilities, inefficient filtration leads to excessive backwashing, higher chemical consumption, increased labor, and rising utility costs.
Natare provides MicroFlo® vacuum sand filtration systems, engineered specifically for commercial swimming pools.
These systems are used in competition facilities, community pools, hospitality environments, therapy pools, and specialty aquatic installations.
MicroFlo® systems may be supplied as part of a complete Natare pool system or installed independently in concrete, stainless steel, or existing pool structures. Many facilities select MicroFlo® filtration as a standalone upgrade.
What is
MicroFlo® Vacuum
Sand Filtration
MicroFlo® uses vacuum sand filtration technology, which operates under negative pressure rather than the positive pressure used in traditional high-rate sand filters.
Because water reaches the filter by gravity, the system:
- Reduces pump strain
- Lowers electrical consumption
- Improves filtration efficiency
- Minimizes backwash frequency
The open-top stainless steel filter tank allows direct visual inspection of the filtration process and easy access for maintenance. MicroFlo® systems are fabricated from low-carbon 316L stainless steel (or carbon steel where appropriate) and feature corrosion-resistant internal assemblies designed for long-term durability.
How MicroFlo® Saves Time,
Water, and Money
MicroFlo® filtration systems are engineered to reduce daily operational burdens.
Save Water
MicroFlo® systems can reduce backwash water consumption by up to 80 percent.
Through optimized hydraulics and air-boost backwash technology, significantly less water is lost during cleaning cycles.
Save Money
Longer filter cycles — typically 30 days or more — reduce maintenance labor and water replacement costs compared to conventional pressure sand filters that may require backwashing every 3 to 5 days.
Reduced water waste also lowers chemical demand, heating costs, and refill expenses.
Save Time
MicroFlo® systems eliminate the need for separate hair and lint strainers, saving staff time daily.
Systems are delivered to the project site complete with:
- Pumps
- Valves
- Controls
- Filter media
- Pre-engineered piping assemblies
This prefabricated filter plant design can reduce installation and construction time by more than 80 percent compared to traditional field-built systems.
Designed for Efficiency and Operational Control
MicroFlo® systems are engineered to maintain consistent water quality under varying bather loads.
Key features include:
- Open-top filter tank for easy inspection and access
- Precise control of filter flow rates
- Flow rates up to 20 gpm per square foot
- Chemically inert interior surfaces
- Corrosion-resistant internal components
- Available compact and wet-well configurations
- Multiple tank arrangements to suit facility size
- Modular Hi-Rate horizontal sand filter configurations
The open tank configuration allows visual monitoring of filtration performance without shutting down the system.
In many installations, MicroFlo® vacuum sand filters function as both filtration system and balance tank.
This dual functionality:
- Reduces mechanical room space requirements
- Simplifies hydraulic design
- Improves system efficiency
- Reduces additional construction costs
This integration makes MicroFlo® particularly effective for renovation and retrofit projects.
MicroFlo® filtration systems are available in a wide range of sizes and configurations.
They are suitable for:
- Public and community pools
- Competition and training facilities
- Hotel and resort pools
- Therapy and rehabilitation pools
- Specialty aquatic environments
Systems can be configured as compact units or arranged in multiple-cell modular designs for large facilities.
Small-footprint Hi-Rate horizontal filters are designed to fit through conventional doors, making them ideal for tight mechanical rooms and renovation projects.
MicroFlo® systems are not limited to stainless steel pools.
They can be installed in:
- Stainless steel pool systems
- Concrete pools
- Renovation projects
- Existing facilities requiring filtration upgrades
Some projects include complete Natare pool systems. Others involve MicroFlo® filtration only. Configuration depends entirely on project scope.
For new facilities, MicroFlo® systems are coordinated with mechanical and hydraulic design to ensure efficient commissioning.
For renovation projects, MicroFlo® filtration systems are ideal upgrades due to:
- Reduced installation time
- Flexible configuration options
- Minimal structural impact
- Compatibility with existing pool infrastructure
