Re: Wattenburg Improvement Assn.
Dear Mr. Warden:
I have reviewed both chlorination systems and am very familiar with the Chlor-Tech unit. I know
how to start it up and train the operator to run it. I have several concerns with the Miox system:
(1) in order to install it, the town will need to provide a drain line to the sewer to eliminate the
Miox waste stream, which has a pH of 12 and is approximately 40 gallons per hour, I expect the
cost of handling the waste stream to be prohibitive to the town of Wattenburg, since there are no
facilities available or planned to accommodate this waste stream. The Chlor-Tech system has no
liquid waste stream but will passively vent hydrogen gas to the atmosphere.
(2) The mixed oxidant generator tank produces 9.4 gallons/hour which is 225.6 gallons of
oxidant per day, yet the supplier of the Miox system has a day holding tank of only 55 gallons.
This would indicate a detention time of 6 hours which means that an operator would have only 6
hours to attend to an emergency. While the Chlor-Tech system allows in excess of 24 hours to
respond to any situation. We should look at the cost of Miox supplying a day tank equal in
capacity to that of the Chlor-Tech tank.
(3) The Chlor-Tech system requires a periodic cleansing of the cell pack using a dilute acid
solution. The Miox unit requires a factory exchange of the reactor membrane and therefore it
becomes prudent to store a spare on site which is not included in their bid.
(4) The Miox system requires a 220 outlet compared to the 120 of the Chlor-Tech system which
would be an added installation cost, since we priced the electrical outlets to be 120.
I would recommend that we go with the Chlor-Tech system, as I am more familiar with it and the
installed price is lower. ( I am referring to #1 about the drain line.) I believe that the $250
difference will be more than compensated by the lower installation and maintenance of the Chlor-
Tech system. I think that most of the replacement costs for pumps, motors, tanks, electrical and
reactor components are significantly cheaper for the Chlor-Tech system. Please contact me if you
have any further questions or comments.
