Loop the loop
A pressurized vessel used to dose chemistry to a chilled water loop
What is a bypass feeder
The process of opening a valve to release water from a boiler
What is blowdown
A type of bacteria that survives in the absence of oxygen
What is anaerobic
Also the last name of the ghost in 'A Christmas Carol', this cooling tower manufacturer is known for their open ended induced draft design
What is Marley
This biocide is just water with an extra oxygen atom
What is hydrogen peroxide
This metal is a component of many closed loop treatments and is common in loops containing aluminum
What is molybdenum
This oxygen scavenger is usually catalyzed with cobalt for a quicker reaction time in steam boiler systems
What is sulfite
A common bacteria in laboratory studies, this bug is often indicative of fecal contamination and can cause gastrointestinal distress
What is e.coli
Measured in microsiemens typically, this reading is used to control bleed in a cooling tower
What is conductivity
This component, commonly found in antifreeze, is also an excellent food source for bacteria in a system
What is glycol
This inhibitor component is specifically designed and added to our treatment products to prevent corrosion of yellow metal components such as copper
What are azoles
This boiler system component can be tray or spray type and when used properly is effective at mechanically removing oxygen from boiler feed water.
What is a deaerator (DA) tank
Abbreviated to cfu, this is the measure per milliletre of bacterial activity in a water sample
What are colony forming units
This type of cooling that allows cooling towers to reject heat so effectively
What is evaporative cooling
This soft metal is alloyed with iron to create galvanized coatings
What is Zinc
When a chilled water loop is losing nitrite but there are no water losses and the conductivity does not drop we suspect this is happening
What is nitrite reducing bacteria
This type of steam boiler typically has components called a mud drum, steam drum and risers
What is a water tube boiler
Smaller than bacteria, these species are removed by sub nano filtration and are a major cause of illness worldwide
What are viruses
These plastic components help stop water droplets from leaving a cooling tower with the air flow
What are drift eliminators
This metal, common in plastic injection molding tools, is also found in most antiperspirant deodorants
What is aluminum
Used in high pressure high temperature hot water loops, this chemical is also an excellent oxygen scavenger and system passivator
What is DEHA
Named for two people, this valve is common to control water levels in a fire tube boiler
What is a McDonnell Miller valve
This type of corrosion is very damaging and is often found underneath biofilms in hydronic systems
What is microbiological induced corrosion
This type of evaporative cooling system does not have a tower fill but instead has a tube bundle inside the tower where heat exchange occurs
What is an evaporative condenser (fluid cooler)
These compounds with an -NH2 group in an organic molecule are common condensate treatment program components
What are amines
