Bubbles cause problems. Liqui-Cel can help.

Bubble formation arises from pressure and temperature fluctuations, pump cavitation, or system leaks, and dissolved gases coming out of solution. In closed systems such as piping or tubing, entrained bubbles disrupt fluid processes and instrumentation, they cause

Pure water (ultrapure water) is essential for the production of hydrogen (H2), a critical fuel for hydrogen fuel cells. Despite its importance, H2 is not readily available in nature, necessitating energy-intensive processes to generate it.

Measuring pH properly in pure and ultrapure water is difficult. pH is critical for process control and for preventing corrosion for example.

Abstract:
Electrodeionization (EDI) is a continuous separation process that uses a DC voltage force t

USP concurs: SnowPure’s experience says that heat sanitization should be between 72-80°C:

• Bacteria are killed at temperatures above 65°C.
• Most bacteria are killed at 60°C, and essentially all bacterial are killed above 65°C.
• Two common protocols have emerged for sanitizing validated high purity water systems:72°C for 30-60 minutes (bacteria killed in seconds)
• 80°C for 15-30 minutes (bacteria killed in milliseconds)

In México, EDI (Electrodeionización) is used to produce pure and ultrapure water for both Generación de Energía y Farmacéutica (USP PW y WFI).

The challenge for pure and ultrapure water in Mexico is the silica level.
SnowPure works in México with OEMs to choose technologies and processes that will enable good

Measuring pH properly in pure and ultrapure water is difficult. pH is critical for process control and for preventing corrosion for example.

pH of Ultrapure Water

pH of Ultrapure water is 7.00. The only ions present are H+ and OH-, and since these must be in balance, the pH is 7. Don’t try to measure the pH of Ultrapure Water! If you are above 16 Megohm, pH is between 6.95 and 7.05.

EDI for Dealers is now a reality. Ultrapure water is a concern for water treatment companies who service critical applications such as Laboratory and Pharmaceutical. You must apply the right technology for your customers’ needs, while remaining competitive and realizing a reasonable profit.

EDI Value Proposition:
PEDI servicing can be expensive and can keep customers from contracting with you. Accounts that are far away (meaning costly truck trips back a

SnowPure Water Technologies has the prime position in the USA Pavilion (booth 615) at the upcoming Aquatech Mexico exhibition, September 4-6, 2018.

EDI, Why FCE is Important for Electrodeionization System Performance

The performance of electrodeionization (EDI) systems depends upon several key feed water constituents. When these constituents are considered together a Feed Conductivity Equivalent, or FCE may be determined.

For an electrodeionization system to operate properly, the feed water must be high-quality Reverse Osmos
