EMERGENCY POTABLE WATER UNIT
With the local concern of water quality from the algal bloom increase in Lake Erie, IFM was contacted by a local Municipal Water Department to build two Emergency Water Treatment Units (EWTU). These units were designed to treat, produce and dispense potable water.
The algal blooms found in Lake Erie are photosynthetic blue-green algae, also known as Cyanobacteria. Cyanotoxins are byproducts of the multiplication and breaking of cyanobacterial cell walls. These cyanotoxins can lead to hepatotoxicity, causing complications to the liver and even promoting liver cell death can occur.
With this information IFM designed the unit to remove these contaminants. The contaminated water goes through a twin alternating water softening unit then leads to activated granular carbon cartridge. Carbon is often used in water purification to absorb a wide variety of harmful contaminants. The water is then fed to a reverse osmosis system to remove any further dissolved solids, toxins, ions and salts.
The processed water is then sent to a holding tank and then into a disinfection process. The unit uses ultraviolet light to disinfect the permeate water. Any bacteria that has been destroyed by the UV light will be filtered out through a 0.2-micron filtration element.
For more information on this EWTU please see attached case study or contact IFM for further information.
