Pool Filtration

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.

Acts as a Balance Tank

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.

Flexible Configurations

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.

Compatible with All Structures

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.

Suitable for New Projects

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
