THM Removal System Successfully Removes Over 65% Of THM Species In Water Storage Tank At The End Of 60 Mile Transmission Line
THM Removal System Successfully Removes Over 65% Of THM Species In Water Storage Tank At The End Of 60 Mile Transmission Line

In Canada and the western United States, long treated water transmission lines are frequently utilized to convey potable water to rural communities. These long transmission lines combined with chlorine for water disinfection can often create the requisite conditions for the formation of undesirable disinfection-byproducts (DBPs). One of the most common DBPs is a family of volatile compounds called Trihalomethanes (THMs) which are regulated in Canada to a level of 100 ppb (part-per-billion) annual average and in the US to a level of 80 ppb.

Generating Disinfectants From Water: Could In Situ Electrolytic Production Be The Future?
Generating Disinfectants From Water: Could In Situ Electrolytic Production Be The Future?

Chemical disinfection using strong oxidants involves the transportation, storage, and handling of unstable and/or aggressive and hazardous chemicals. The production of oxidants at the location where they are to be used has therefore been a preferred option, especially in small-scale or remote installations. On-site electrolysis of NaCl for the local production of chlorine or hypochlorite, or the production of ozone-enriched oxygen by silent discharge has been standard for years.  However, it is possible to take the idea of producing chemical disinfectants locally a step further and look at in situ techniques, i.e. at devices, which produce oxidants in and from the water to be treated.

Pipeline Flash Reactors for Mixing & Contacting Pipeline Flash Reactors for Mixing & Contacting

Pipeline Flash Reactors™ (PFRs or spool pieces) utilize high velocity mixing to transfer ozone or oxygen-enriched sidestreams into bulk water flow, all within a compact footprint. With a PFR, ozone or oxygen mass transfer occurs in the pipeline within seconds, eliminating the need for additional tanks or basins. Whether it is providing ozone for water purification or increased dissolved oxygen for wastewater, Mazzei’s PFR uniformly distributes gas into the water and minimizes the size and cost of gas contacting.

Disinfection: TCL Total Chlorine Analyzer Disinfection: TCL Total Chlorine Analyzer

Total chlorine measurement is essential in the control of chlorine in water before its return to the environment in a wide range of industrial applications including desalination. It also provides accurate reporting to the EPA about that control. To meet EPA requirements, the instrument must be reliable for long periods of time and monitor down to 500 ppb. The Rosemount Total Chlorine Measurement system from Emerson meets and exceeds all requirements while saving money through the use of low-cost reagents.

Drumming Up Chemical Injection Drumming Up Chemical Injection

The operating ranges for chemical injection need to be large because of the variability of flow in many treatment operations. As Bill McDowell, Vice President of Operations with Blue White Industries explains in this Water Talk interview, “You might be down to as low as 5 or 10 milliliters a minute and then one hour later; you might need to pump 15 gallons a minute out of the same pump and through the same sensor.”

ABOUT DRINKING WATER DISINFECTION

WATER DISINFECTION

Water disinfection is the process of removing unwanted chemicals, biological contaminants, suspended solids and gases from contaminated water. It is also the elimination, deactivation or killing of pathogenic microorganisms.

Methods used include physical processes such as filtration, sedimentation, and distillation, biological processes such as slow sand filters or activated sludge, chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light.

Ozonators produce small quantities of ozone which is a strong oxidizing agent that kills pathogens over a short period of time.
