This is a Salient Characteristics document for a federal contract opportunity issued by 20 Civil Engineer Squadron (20 CES) to procure dry chemical feeder systems for water treatment applications.

20 CES seeks to purchase two Series 32-055 volumetric dry screw feeder systems designed to dispense soda ash at a rate of 5-10 pounds per hour. The systems will be installed at well 4 and well 6 to replace existing soda ash mixers. Each volumetric screw feeder includes a 1-1/2" stainless steel feed screw and discharge spout for granular service, a low-speed gear box with 0.60 cubic feet per hour maximum feed rate and 4-speed drive pulley, a 1/6 cubic foot stainless steel inlet hopper with agitation and cover, a 1/6 HP permanent magnet DC motor (TENV), and a wall-mounted NEMA 12 control unit featuring power on/off switch, motor remote-local stop switch, auto-manual switch, auto dosage potentiometer, and digital feed display with adjustment capability. Each system includes a solution mixing tank consisting of a 35-gallon rectangular stainless steel tank with cover, tank mounting parts for the feeder on the stainless steel cover, a dust arrestor with water line and spray nozzle, and a mechanical mixer equipped with a 1/4 HP motor rated 115/230 VAC (TENV) and jet agitator. The support requirement references USGI Chemical Feed, Inc. File No. 202501-41232.
