RW0.5i

The new RW0.5i is a simplified version of the RW0.5 that uses impeller mixers instead of paddle wheels.  The impellers provide an adjustable speed mixing that integrates directly into the control system.  The RW0.5i uses the same raceways, stand, and accessories as the standard RW0.5 but eliminates the paddles, motor, and VFD.

REDUCE COMPLEXITY

The new impeller mixed Algae Raceway allows for a much simpler installation. Operation is controlled directly through neptune control system. A channelized flow is achieved by directing the impeller down one side of the raceway.

Magnetic mount impeller mixer

The 24V DC impeller mixer is installed with a magnetic mounting bracket. A single wire is used for both power and control. The mixer automatically stops if it is pulled out of the water or the water level becomes too low preventing accidental burn out.

Major cost savings

By eliminating the paddle wheel, the total cost of equipment is greatly reduced. The impeller mixer is simple and effective for mixing most types of algae cultures. We do not recommend using the impeller mixer for shear-sensitive or flocculated cultures. In the future, if your mixing requirements change, a paddle-wheel is compatible with this system and can be added on.

RW0.5

Small raceways intended for initial inoculation culture development or programs just getting started in algae research.  The culture area of this raceway is 0.5 m² and the volume is 100 liters at maximum depth of 20 cm.  Stands elevate the ponds (0.6 m) to allow for easy draining to down stream processes.  The smaller design allows you to operate more raceways efficiently and enables duplicate and triplicate experiments.

RW22-RW101

RW22 MBE Algae Raceway 22m2
RW29 Algae Raceway 28m2

PreFab Algae Raceways up to 101 m²

This first-of-a-kind prefabricated Algae Raceway featuring APIAC technology is intended for medium to large-scale operations.  Take the guesswork out of building your own algae raceways with these patent-pending modular algae ponds, ranging in size from 22 to 101 m² (6.5 to 30 m³).  Don't waste your time designing from scratch, sourcing the materials from countless vendors, then dealing with complicated custom installations. 

RW22-RW101 sizes are sold as complete and integrated systems including containment walls, liner, paddle wheels, and optional control systems.  Installation is quick and painless with no specialty labor or contractors needed. The only site requirements are level, compacted ground and a 110-230 VAC, 50-60Hz power source.

RW1,000, RW2,000, RW4,000

The largest raceways that MBE provides are pre-designed Algae Raceways which have an area of 1,000, 2,000, and 4,000-m2.  These ponds utilize earthen -type construction and a new composite paddle wheel.

 
MicroBio Engineering Algae Raceway Paddle wheel

COMPLETELY FRP PADDLE WHEEL

The patent pending FRP paddle wheel is significantly lighter than alternative metal shaft designs, which allows for longer unsupported lengths and reduced overall construction costs in large scale raceway systems. Metal paddle wheels require custom welding and heavy equipment to install, whereas the FRP paddle wheel can be assembled in the field using standard hardware and hand labor.  

FRP is highly corrosion resistant, which allows operation in the harshest conditions, including salt water cultures, at substantially lower costs than 316 stainless steel.  UV resistant and food-safe coatings improve longevity and reduce maintenance requirements.

The newly designed paddle wheel was a collaboration between MicroBio Engineering Inc and Colorado Lining International Inc.    

Algae raceway MicroBio Engineering RW4000

Improved Paddle Wheel can be:

  • Installed without the need of heavy equipment;
  • Easily replaced if damaged using basic hand tools;
  • Shipped very efficiently in parts and pieces including overseas ocean container freight;
  • Installed in harsh environments because of the high corrosion resistance;
  • Longer and unsupported lengths can be achieved than heavier steel shaft paddle wheels
 

Pre-designed Algae Raceway means that all materials are provided including:

  • Construction plan set
  • Paddle wheel, motor, mounting hardware, inverter
  • Plastic membrane liner

Onsite earth grading, compaction, and small amount of concrete must be completed by customer.  

Control Systems

pH Control

Control pH with our Neptune Apex control system.  CO2 dosing is automated with adjustable set points. pH electrodes are standard BNC type connections which allow for affordable routine replacement.  All controls are custom installed and pre-programmed in a non-metallic weather-proof enclosure.  The large size of the enclosure allows for multiple control modules and motor controllers to share a single enclosure reducing the price.  The enclosures come standard with a fan cooling system and an emergency stop switch.  Wall mounting hardware is supplied standard or the enclosure can be mounted directly to any paddle wheel frame for an RW22-101.
