Maintaining the integrity and efficiency of industrial water systems is a constant challenge, with microbial growth being a primary culprit. NINGBO INNO PHARMCHEM CO.,LTD. provides 2,2-Dibromo-2-Cyanoacetamide (DBNPA), a highly effective biocide that offers robust solutions. This article presents case studies illustrating DBNPA's performance in critical industrial water treatment scenarios.

Case Study 1: Cooling Water System Optimization in a Chemical Plant

A large chemical manufacturing plant experienced significant biofouling in its open recirculating cooling water system. The growth of bacteria and algae led to reduced heat exchange efficiency, increased energy consumption, and the risk of Legionella proliferation. Traditional biocides proved insufficient or had undesirable environmental side effects. Upon implementing DBNPA from NINGBO INNO PHARMCHEM CO.,LTD., the plant observed a rapid reduction in planktonic microorganisms and a noticeable decrease in biofilm formation. The quick-kill action of DBNPA ensured that microbial populations were controlled efficiently, even in the presence of organic loading. The biocide's rapid degradation meant that blowdown water met environmental standards more easily. Within weeks, the system's heat transfer efficiency improved, leading to energy savings and a more stable operational environment. The availability of DBNPA in liquid forms made dosing straightforward.

Case Study 2: Slime Control in Papermaking Processes

A paper mill faced persistent slime issues on its paper machines, causing web breaks and affecting the quality of the final product. The slime, composed of bacteria and fungi, accumulated on equipment surfaces, necessitating frequent shutdowns for cleaning. NINGBO INNO PHARMCHEM CO.,LTD. recommended the use of DBNPA for its effective control of slime-forming bacteria and its compatibility with the wet-end chemistry of papermaking. DBNPA was introduced into the process water at controlled intervals. Its rapid action quickly penetrated existing slime layers and eradicated the microbial communities responsible. This resulted in a significant reduction in slime-related web breaks, improved paper quality, and extended run times between cleanings. The ability to buy DBNPA in convenient packaging further simplified its application.

Case Study 3: Enhancing RO Membrane Performance in a Power Plant

A power generation facility utilizing reverse osmosis (RO) for boiler feedwater treatment struggled with microbial contamination of its membranes, leading to reduced flux and increased cleaning cycles. DBNPA was selected for its compatibility with polyamide membranes and its effective, non-oxidizing biocidal action. Intermittent dosing of DBNPA during system operation, with proper diversion of permeate to drain, successfully prevented bacterial colonization and biofilm formation on the membrane surfaces. This led to sustained high flux rates, reduced chemical cleaning frequency, and extended membrane lifespan. The rapid degradation of DBNPA also ensured minimal carryover into the treated water.

These case studies highlight the practical benefits and broad applicability of DBNPA in industrial settings. NINGBO INNO PHARMCHEM CO.,LTD. is proud to support these industries with a reliable and powerful biocide solution. For companies looking to purchase DBNPA and enhance their water treatment programs, our product offers proven performance and economic advantages.
