To eliminate oil and grease, Bio-Circle L needs oxygen and a temperature of 37°C. The Bio-Circle™ machine provides these conditions. In other cleaning tubs, the brush, the pumps and the unit itself are not designed for use with water-based products.

In this case, if the surface of the liquid is free from oil, the microorganisms go into a "sleep" mode but stay alive. If the surface is completely covered with an oily film, the microorganisms will not receive oxygen and they will die. In such case, remove the oil using absorbent pads.

No. As a general rule, the Bio-Circle™ cleaner must be replaced. However, there is a trick to avoid changing all of the liquid. Depending on the condition of the solution, it consists of removing a minimum of 40L of the solution (which will be kept in clean containers) and replace them with 40L of new Bio-Circle L to add living microorganisms into the machine. The machine must be kept running. The 40L of Bio-Circle L liquid removed from the machine can be used at a later time for top up. This procedure can only be applied if the microorganisms have not been "poisoned" by solvents or disinfectants.

It is recommended to wear gloves, especially during a prolonged use, because the liquid Bio-Circle L liquid has strong degreasing power and because oil/grease can irritate skin.

The Bio-Circle™ system has been designed to remediate oil and grease residues normally found on parts to be cleaned in daily operations. Excess oil and grease should be disposed of prior to cleaning the parts. The Bio-Circle™ system should not be used as a waste dump.

Bio-Circle L cleaning fluid is compatible with all ferrous and non-ferrous metals, most plastics as well as painted surfaces, etc. However, test for material compatibility before soaking sensitive materials such as plastics or painted surfaces.

Unused Bio-Circle L in its container is an almost clear liquid. Once used, the liquid becomes dark from contact with oil and grease. This is normal and does not affect the cleaning performance of the Bio-Circle L at all, nor does it give an indication of the bioremediation activity.
