| Should we use the Bio-Circle L liquid only with the Bio-CircleTM machine or can we use it with other cleaning tubs? | | To eliminate oil and grease, Bio-Circle L needs oxygen and a temperature of 37oC. The Bio-CircleTM 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. | | |
| What happens when the power supply is cut or when the machine is unplugged for two (2) or three (3) days? | | 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. | | |
| Can we continue to use the Bio-Circle L liquid if the microorganisms are dead? | | No. As a general rule, the Bio-CircleTM 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. | | |
| Is it preferable to wear gloves when working with Bio-Circle L? | | 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. | | |
| Can we move the Bio-CircleTM machine easily? | | You can either install the machine on a mobile base or on a lift truck. You must keep in mind that the machine should not remain unplugged for a too long period of time. | | |
| How can we recognize that the microorganisms are no longer active? | | When the oil is no longer eliminated. This can be verified very easily. If, between Friday after closing and Monday morning before work, the quantity of oil on the surface is the same, the Bio-Circle L liquid no longer works. If this should happen, you will also notice a reduction in the cleaning performance. | |
| How much oil/grease can the system handle? | | The Bio-CircleTM 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-CircleTM system should not be used as a waste dump. | | |
| Is it necessary to add Bio-Circle L to the unit during use? | | Under normal use, it is necessary to add Bio-Circle L to compensate for evaporation and loss through liquid drag out (approximately every 6 to 8 weeks). It is important to ensure the Bio-CircleTM liquid is maintained at the proper level (above the second fill line) for best performance. Top up using only genuine WALTER Bio-Circle L liquid and do not add water or any other cleaning solutions. | | |
| Which materials is Bio-Circle L compatible with? | | 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. | | |
| Why is Bio-Circle L turning dark after only a few days of use? | | Unused Bio-Circle L in its container is an almost clear liquid. Once used, the liquid becomes dark from the dies in 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. | |
