BUCKMAN’S TOTAL APPROACH:The only place for growth is on thebottom line.Water is a key player in cooling systems of all types. It serves asan excellent solvent and heat transfer agent. Yet, as water playsthe hero in cooling systems, it also serves as its own worst enemy.While water works to dissolve impurities, these substances canbecome corrosive and destructive. The remaining particulatematter often builds to the point that solubility is no longerpossible and efficiency-threatening scale forms. In addition, waterindiscriminately supports life—including algae and bacteria whichwork to reduce water quality, foul system surfaces and promotecorrosion. High quality water ensures an efficient operation andincreased equipment life.For these reasons, water in cooling systems must be speciallytreated and monitored. When scale and microbiological foulingare controlled, cooling water runs free and clean, maximizing itsability to absorb heat and carry it away, leaving your systems cooland running efficiently.At Buckman, we know the key is water treatment optimization —the ability to not only apply the right chemistries, but also tomonitor and control water quality while keeping it balanced.When you keep contaminants from growing in your system, youcan grow the bottom line—increasing production, reducingdowntime and lowering operational costs.

BUCKMAN’S TOTAL APPROACH:Specialized tools, superior performanceDespite the commonalities found in cooling watertreatment operations, not every water coolingoperation issue is exactly alike. Simply applyinga chemical program to an issue does not alwayssolve the problem. Often times, it exacerbatesthe problem or even multiplies the issue. Thisblind overtreatment or undertreatment has seriousconsequences for system efficiency, treatment costsand the environment. That is why Buckman focuseson continuous research and development ofadvanced diagnostic and monitoring technologiesthat can help improve system efficiency and reducethe capital costs.Buckman has the knowledgeand tools necessary to ensure consistent waterquality and precision dosing, eliminating wastefulspending and boosting productivity.

BUCKMAN’S TOTAL APPROACH:Types of Cooling SystemsThe basic function of cooling water is to remove heat from a process by transferring it from some mediuminto the cooling water for dissipation. There are three basic types of cooling systems: once-throughcooling systems, open recirculating systems and closed recirculating systems.Once-ThroughA once-through cooling system pumps waterinto equipment where it passes across a hotsurface in order to cool it. The water then exitsthe equipment, taking the heat with it. Simpleand effective in a wide range of applications,this system can be undermined by the quality ofthe raw water. Lakes and rivers can bring inDischargeIntakePumpHeat Exchangersuspended matter and pollutants. Well waterscan contribute large amounts of iron and scaleforming materials. Because water is only usedonce, a large amount of water is required.Open RecirculatingThis system sends cooling water out of theequipment and into a pond or cooling tower that isopen to the atmosphere. Here, evaporation occurs,removing heat along with the evaporated water.As a result, the remaining water cools. It is thencombined with makeup water, which replaces theevaporated water, and is, again, sent through thesystem. Open‑recirculating systems are prevalentas water is scarcer and environmental restrictionsare placed on bleedoff discharge.Heat ExchangerEvaporationBlowdownMakeupWaterCooling TowerClosed RecirculatingAll water used to carry heat away from equipmentruns through a heat exchanger, which is cooled byair, mechanical refrigeration or a separate opencooling water system. There is no evapora tion ormakeup water required, so contamination—andthe main tenance that results—is less likely. Sincethe same water is used over and over, waterColdPumpPumpHeat ExchangerHotand sewage costs are lower and environmentalcompliance is easier. Many once-through systemsare converted to closed systems for this reason.Specialized SytemsA specialized cooling system might utilizecompression or absorption-type refrigeration orair conditioning systems, which can be used tocool both processes and work spaces. It mightutilize a cooling coil below the deck of the coolingtower. Or it might include the use of industrial airwashers in which air is filtered, sprayed and thenforced through a series of mist eliminators. Eachsystem has its own unique risks for fouling andmust be treated accordingly.
