Take this short quiz to test your knowledge about industrial water treatment equipment and statistics!
1. On average, what percentage of global freshwater use is attributable to industrial use?
A. 10%
B. 20%
C. 30%
D. 40%
Approximately 20% of all global freshwater use is attributable to industrial use. Learn more about freshwater use.
2. Which of the following industries can benefit from treating water with a reverse osmosis system?
A. Restaurants
B. Healthcare Clinics
C. Printing Facilities
D. All of the Above
A large variety of industries can benefit from the use of an industrial reverse osmosis system, which is capable of stripping from water, the following undesirables: minerals, organic molecules, bacteria and viruses down to 0.0001 microns. Learn more about industrial reverse osmosis.
3. What is the primary difference between reverse osmosis and nanofiltration industrial water treatment equipment?
A. RO uses membrane filtration, nanofiltration doesn’t
B. Nanofiltration uses membrane filtration, reverse osmosis doesn’t
C. RO removes more dissolved minerals than nanofiltration
D. Nanofiltration removes more dissolved minerals than reverse osmosis
The primary difference between reverse osmosis and nanofiltration is that reverse osmosis removes more dissolved minerals. Nanofiltration removes between 80% and 90% of dissolved minerals, while reverse osmosis removes 90% to 99% of these same minerals. Learn more about industrial water treatment methods.
4. Which of the following is a byproduct of hard water that negatively affects boilers, piping and heat exchangers?
A. Scale
B. Iron
C. Sulfate
D. Salt
Scale is a by-product of hard water formed by the crystallization and buildup of dissolved magnesium and calcium ions. If left untreated, scale buildup inside boiler walls and piping will result in a loss of heat transfer and reduce efficiency.

5. A depth filter usually has how many layers of filtration media?
A. 1-3
B. 3-5
C. 5-7
D. 7-9
A depth filter usually has three-to-five layers of filtration media, each of different sizes and densities in a pressurized vessel. Light, coarse material lies at the top of the filter bed with finer and denser material in the lower layers. Learn more about the fundamentals of depth filtration.
6. What are the three main methods of industrial water filtration?
A. Rapid Gravity, Vacuum, and Downflow Filtration
B. Rapid Gravity, Pressure, and Upflow Filtration
C. Sand, Vacuum, and Upflow Filtration
D. Sand, Pressure, and Downflow Filtration
There are three main methods of industrial water filtration: rapid gravity, pressure, and up-flow filtration.

7. The overall effectiveness of a reverse osmosis (RO) system depends on which of the following factors?
A. Feedwater Temperature
B. Feedwater Pressure
C. Upstream Pretreatment
D. All of the Above
The effectiveness of an industrial reverse osmosis system is impacted by feedwater temperature and pressure, and the level of pretreatment the water undergoes upstream of RO filtration to remove membrane fouling contaminants. Learn more about reverse osmosis industrial water systems.
