Activated carbon (AC) filtration is most effective in removing organic contaminants from water. Organic substances are composed of two basic elements, carbon and hydrogen. Because organic chemicals are often responsible for taste, odor, and color problems, AC filtration can generally be used to improve aesthetically objectionable water as well as remove chlorine. AC filtration is recognized by the Water Quality Association as an acceptable method to maintain certain drinking water contaminants within the limits of the Drinking Water Standards.
The customer’s requirements were to reduce contaminants to acceptable standards. Those contaminants included: Organic Mercury, Arsenic, Chromium Complexes, Inorganic Mercury (Hg+2), Benzene, Endrin, Lindane, Methoxychlor, Toxaphene, Trichloroethylene, Paradichlorobenzene, 1,2 and 1,1-dichloroethylene, 1,1,1-trichlorethane and TTHMS.
SYSTEM RECOMMENDATION
The customer contacted Schenck for suggestions on improving their process. After testing the customer’s materials in the Schenck test lab a system was recommended that included the following equipment:
•SacMaster® DHL Stainless Steel Bulk Bag Discharger with Explosion Proof Motorized Hoist and Trolley
The process begins with water being piped through the eductor while the MECHATRON® loss-in-weight feeder continuously meters the powdered activated carbon at a specific setpoint into the extension hopper of the eductor.
The powdered activated carbon mixes with the water in the eductor, which creates a slurry mix of water and activated carbon. This liquid slurry mix is then carried through piping to the injection point on the main raw water line for filtration and purification.
RESULTS
With the use of the MECHATRON® feeder, the customer was able to automate their process and verify the amount of powdered activated carbon being metered into the process.
