SPECIFICATIONS FOR

SERVICE CONTRACT TO PROVIDE CHLORINE DIOXIDE

GENERAL DESCRIPTION

Bids are being accepted for a service contract to purchase sodium chlorite to produce chlorine

dioxide. The chlorine dioxide shall be generated onsite for use as a disinfectant.

The chlorine dioxide system shall be installed at the City of Port Arthur's water treatment plant.

The treatment plant treats surface water from the Lower Neches Valley Authority for drinking

water. The average daily flow of the treatment plant is approximately 16.0 mgd with a

maximum of 40 mgd. The C102 dosage rate of the equipment must be variable from 0.25 mg/l

to 3.0 mg/l (ppm) at the desired plant flow rates without loss of generator efficiency. It is

estimated that we will need about 500,000 pounds per year of sodium chlorite.

Bidder shall supply a list of at least four systems including names and telephone numbers of

facilities wherein they have installed and are currently servicing chlorine dioxide systems. The

system which is bid must be CURRENTLY accepted by all applicable regulatory agencies

including the Texas Commission on Environmental Quality.

The successful bidder shall supply a system for generating CHLORINE DIOXIDE as an

aqueous solution from the reaction of SODIUM CHLORITE and CHLORINE GAS, the 3

units shall be capable of delivering the required amount of Cl02 at each feed point on a

continuous basis, 24 hours a day, to meet the CT and TTHM requirements set by the EPA

and TCEQ.

The 3 units shall be properly sized, and designed specifically for the intended application set

forth in the general description above. The unit shall be equipped with a Siemens non

contact magnetic flow measuring device and stream pH measuring device with 4-20 mA

output signal to assist in maintaining system efficiency, and to prevent waste of plant

water. Shall be equipped with loss of chlorine and/or water feed automatic shutdown. A

fully equipped standby unit shall be provided. The unit shall not require pH measurement

or adjustment for operation. Each unit shall be provided with necessary devices to

manually adjust the chlorine dioxide feed rate to provide means to accurately split clo2 into

4 separate injection points with each generator capable of supplying at least 2 injection

points and each capable of supplying any 2 of the 4 points.

The reaction product purity shall not be less than 95 percent Cl02, and the total by-products must

remain lower than 1.0 mg/1(PPM), for chlorite in the distribution system at the approved

sample locations at all times.

Bidder shall supply all equipment and materials necessary to generate the solution onsite. Bidder

must furnish a device for equally splitting the chlorine dioxide into two different injection

points. Except for electricity, plant water at system pressure, and chlorine gas, All

equipment and materials furnished shall be suitable for the application specified, and shall
