■Overview of the Circulating Biotron method
The Circulating Biotron method, which features an energy- and space-saving design,
quickly improves water transparency.

In the past, it has been difficult to control algae growth and restore transparency because there has been no sure-fire technique for purifying ponds. The Circulating Biotron method can be easily used with just a 100 V electrical outlet and requires no major installation work. We developed this new purification system so that it could increase transparency and improve bottom quality in lakes and marshes, ponds, drainage ditches,reservoirs, golf course ponds, park ponds, and garden ponds in an energy-efficient and inexpensive manner.The Circulating

Biotron method is patented in Japan.

With the launch of the Simple Circulating Biotron BT-100, we have delivered an even higher level of energy efficiency and low cost in a
package that can be installed even more easily.

Simply install a model based on the size and shape of the pond to control transparency automatically using a purification agent. The product yields results more reliably than conventional purification techniques with effects that extend over a large area to create a fresh, transparent water environment.

By using the Circulating Biotron method in conjunction with our biologically active formulation Aqualift 1600PN/LN, you can also break down nitrogen that causes eutrophication, toxic substances, and sulfides and organic matter that degrade bottom quality to restore aquatic organisms such as bottom-dwelling microorganisms and protozoa, thereby promoting the purifying effects of the food chain.

※See our manually applied Pond CF product for applications involving moving water such as garden ponds, golf course ponds, ponds at shrines and temples, and ponds at other facilities where the water circulates.

Circulating Biotron method BT-200 and BT-500

■Devices descriptions
These models are designed to accommodate a variety of applications while taking up only a small amount of space.
Control device

Circulation device

The control device controls operation of the circulation device, to which it sends a constant amount of purification agent.
BT-200: 100(H)×90(W)×65(D)cm
  
The circulation device generates a gentle flow (circulation) of water throughout the entire pond while mixing pond water.
K-500: 26(H)×40 (W)×64(D)cm (not including pedestal)

The Circulating Biotron method was certified under the Medium and Small Enterprise Creative Activity Promotion Act (Japan Research Industries and Industrial Technology Association No. 9-392) by Fukuoka Prefecture on November 25, 1997.

■The Circulating Biotron method is designed to be energy- and space-efficient.
The system's devices use a 100 V or 200 V main power supply and consume about 630 W of power. The energy-saving compact model uses just 100 W of power.
The system is inexpensive to install compared to a filtration system or other equipment. In addition, since there is almost no need to replace filter media or consumables, running costs can be kept low.
The control device is compact so that it won't interfere with the surrounding view or scenery. It's also quiet in fact, it's almost silent.
By adjusting the number of devices used, it is possible to accommodate a variety of bodies of water, including lakes and marshes, dams, golf course ponds, garden ponds, park ponds, and castle moats.
Installation work can be completed in a day.

■Safety testing of the purification agent
The system uses a safe purification agent that does not impact the ecosystem. The safety of that agent has been verified by toxicity testing using Oryzias latipes as well ashealth-related testing andtesting related to required tap water characteristics as required by the Water Supply Act, among other tests.
Click here to view water quality test results and safety test results.

■Purified water can be reused as-is.
Purified water from agriculture reservoirs, golf course ponds, recreational ponds, park ponds, and other bodies of water can be used to water crops, lawns, ornamental trees, and other plants as-is, without further treatment. Water from industrial sedimentation basins can also be used for various facility-specific uses without further treatment.

■Maintenance work and water quality testing
Once a month, our personnelwill visit your site to maintain and manage transparency and water quality, replenish the purification agent, measure water quality, inspect and clean the devices, replace consumables, and submit a monthly report, among other services.
We can also compile graphs tracking environmental water quality test parameters such as nitrogen, phosphorus, COD, pH level, and transparency along with reports. In addition, we can measure other water quality parameters.
Customers can also replenish the purification agent and otherwise manage the system on their own, based on our advice. In this case, you will need to report information such as transparency and other data describing the status of the pond (based on visual observations). In some cases, we ask that customers send us a sample of the pond's water (500 cc).



Simple Circulating Biotron method BT-100

The Simple Circulating Biotron method BT-100 is a purification device that has been developed so that customers can install it themselves in garden ponds, drainage ditches, park ponds, fishing ponds, golf course ponds, and industrial sedimentation basins.

This product makes it possible to improve, maintain, and manage pond transparency and water quality at lower cost than conventional means simply by reporting information about the condition of the pond and then replenishing purification agent according to the water quality and type of pond based on our advice.

■Product features
Since it's lighter than previous devices, the BT-100 is easy to transport, install, and manage.
The circulation device is installed in the pond.
Just connect to a 100 V power supply to use.
The BT-100 cannot be used in ponds with less than 100 tons of water. Instead, address
water quality issues in such bodies of water by adding water or using a filter.

■Example installations
Before After
 AShrine, Fukuoka Prefecture: About 1,200 tons


Before After
 APark, Saga Prefecture: About 40,000 tons


Before After
 APlant in Hyogo Prefecture: About 7,000 tons


■Devices descriptions
The BT-100 can be used in a variety of applications thanks to its energy- and space-saving design.

Reference selling price: ¥450,000 to ¥550,000 (one control device and one circulation device)
Pricing reflects typical wiring and submersible pump requirements and may vary depending on the specific characteristics of the pond and installation location.
※Additional fees apply if we install and set up the system.

To improve water and bottom quality, we recommend using Aqualift 700PN or Aqualift 1600PN/LN (for large ponds) in conjunction with the BT-100.
To increase transparency, we recommend introducing our manually applied control agent (clarifying agent) Pond CF into the water flow of the pond's circulating pump in garden ponds, golf course ponds, and other bodies of water of 100 to 1,500 ㎥ in size.

■An energy-saving design keeps operation economical.
With a 100 V main power supply and pump power consumption of 150 W and 230 W, the BT-100 is energy-efficient and economical to operate.
Installation work can be completed in several hours.

■If you install and maintain the system
Our maintenance personnel will offer advice about installing the device.
※If necessary, we can install or be present at the installation (separate fees apply).

During subsequent regular maintenance, our personnel will offer advice concerning the amount of purification agent with which to replenish the control device, adjustment issues, and other aspects of system operation if you report the condition of the pond to us. (※We'll send you purification agent based on the water quality and characteristics of the pond.)

■If we install and maintain the system
Our maintenance personnel will travel to your site, where they'll install the Circulating Biotron devices, set them up, and adjust them.
During subsequent regular maintenance, our personnel will visit your site, where they'll inspect and adjust the system, replenish purification agent, and maintain and manage water quality, transparency, and other parameters while checking the condition of your pond.

Contact us with inquiries about topics such as water or pond conditions.
