Industrial Water Biocides and Algicides
TL;DR Choose a microbial-control family from the water system, target organism or biofilm problem, required contact pattern, pH and temperature, wetted materials, discharge conditions and compatibility with the scale/corrosion program. Oxidizing and non-oxidizing products solve different operating needs; neither is an automatic default for every cooling-water or process-water system.
Biocides and algicides help control bacteria, fungi, algae and biofilm in cooling water, wastewater and industrial process systems. Product selection begins with the organism or operating symptom and the system conditions—not with a universal oxidizer/non-oxidizer schedule.
Families in this category: oxidizing disinfectants such as TCCA and SDIC; non-oxidizing options including benzalkonium chloride, glutaraldehyde, isothiazolinone, DBNPA and THPS; and formulated microbial-control products. Permitted use, label directions, contact time, pH, temperature, materials and discharge route must be checked for the exact grade and destination.
Choose the next route by operating decision
Build the microbial-control route
Start with the cooling or process system, pH and temperature, organic and ammonia demand, contact pattern, biofilm location and the microbial indicator used by the site.
Plan a cooling-water program →Check oxidant/inhibitor compatibility
If corrosion, haze, deposit control or residual behavior changes when the oxidant feed runs, map the first contact and test the actual inhibitor package in representative water.
Use the compatibility workflow →Compare a non-oxidizing route
When contact time, biofilm penetration, material exposure or oxidant demand drives the decision, compare suitable non-oxidizing families under the exact permitted-use and system conditions.

Biocide and algicide are two powerful methods of controlling nuisance organisms in aquatic environments. Biocides are toxic chemicals that target living organisms, while algicides target photosynthetic organisms, such as algae. Both types of chemicals can be used to reduce the growth of unwanted populations or kill them outright. However, these substances can have a negative effect on other beneficial species in the ecosystem if not used correctly and responsibly. To prevent damage to beneficial species, it is important to use biocides and algicides only when necessary and with extreme care.

Oilfield injection-water microbial control
For injection water, select the control route from the microbial risk location, water source, salinity, temperature, residence time, materials and delivery pattern. Start with the application path, then compare a relevant biocide family and verify it at the asset.
