This product is a registered biocide under Agriculture Canada’s “Pest Control Products Act”. (Registration#28339). Myacide GA25 is a glutaraldehyde-based biocide in a clear liquid form.
Myacide GA25 is effective in controlling both aerobic and anaerobic (sulfate reducing) bacteria. It is compatible with all water based fracturing and drilling fluids and can be neutralized prior to disposal (see below). The recommended treatment is dependent on the severity of the bacterial contamination. As a pre-treatment, add 0.1-0.5 L/m³ to the fluid system and monitor with microbial dip slides. For already contaminated fluids, add 0.5-2.0 L/m³ treatments until bacterial control is achieved.
Microtox Analysis: A series of microtox tests have determined the following procedure will deactivate Myacide GA25 and should provide a non-toxic response in the fluid.
- Increase the pH of the fluid to 12.0 and hold for four hours.
- Neutralize fluid back to pH 7.0 with an appropriate acid.
