The management of Microbiological contamination in water handling systems is of vital importance in any protective maintenance program. The more efficient the analytical procedures you have in place, the more effective the corrective action you can take. PMAC offer a range of Bio-Side streams, including low pressure Acetyl models, rated to 300 psi or the high pressure stainless steel or titanium model (standard rated to 3500 psi working pressure).


The standard design typically holds between 8 and 24 biostuds for the analysis of sessile microbiological contamination in water injection or produced water handling systems. It can be mounted vertically or horizontally and it is attached to the operating system directly from a standard sample point. In addition the outer valve may be simply run to a drain or looped back into the system.


​Once installed the Side stream is easy to use and maintain. The water flow rate is set and the continuous monitoring commences immediately. Once a pre-determined flow or time lapse has been reached, a series of valves isolates the process system from the side stream, a bio-stud holder can then be removed and replaced as necessary. Analysis of the bio-stud is easily carried out using standard kits. Subsequently any necessary treatments can be introduced, overall proving an effective microbiological management of water systems.


​A Robbins-type Bio-side stream unit, commonly used by Chemical Companies for the on-site testing of biocide efficacy; is suitable for use with oilfield water injection systems or other high volume water handling plant. The unit comprises four independent flow chambers, each with ten individual bio-stud access ports, and a chemical injection facility contained in a stainless steel skid. Each of the three test channels is fitted with a chemical injection facility enabling three separate treatment regimes, or biocide chemicals to be evaluated simultaneously. A separate channel is used for control (untreated) purposes.


​PMAC also manufacture a multitasking side stream, that utilises multiple flow through cells in series, allowing for the user to monitor for corrosion rates (LPR and or ER) in addition to biocide efficacy. PMAC have also adapted this side stream to offer mini-weight-loss corrosion coupons, offering longitudinal studies in parallel with biocide monitoring. The PMAC Multi-tasking Side stream is a cost effective technique enabling greater Process Measurement And Control in a single system. When fitted with injection ports, these systems allow for combined chemical optimisation trials (biocides, scavengers, inhibitors).
