Title: Drum filters

Background:

USDA. ARS National Cold Water Marine Aquaculture requires new drum filters for the smaller experimental systems. Drum filters are used to remove particulate matter from the water. The smaller experimental systems are designed to be used with drum filters.

Technical requirements:

1. Drum filter and components must be made of plastic or fiberglass except for motors and limited fasteners.

2. Must be direct drive for simplicity of service and corrosion resistance.

3. Drum filter motors must be 3 phase 480 volt compatible.

4. Drum filter screens must be 60 microns of less.

5. Screens must be easily removable for cleaning and servicing.

6. Must have a mechanism/device (combs/rakes) to remove internal floating material.

7. Must be able to handle flow rates between 24 gallons per minute (gpm) and 60 gpm.

8. Must come with a control panel (NEMA 4X) for each drum filter.

9. Must come with two 230V/1PH booster pumps, two pressure tanks rated to the operating pressure of the drum filters and control panels for the booster pumps. One booster pump system will operate three drum filters and the other booster pump system will operate the other two drum filters.

10. Plumbing must be compatible with the current drum filters (Hydrotech HDF501‐1P (2006), see attached photos).

11. Must be compatible with freshwater and seawater.

12. Overflow must return to the system and not cause water loss in case of filter failure at maximum flow rate.

13. Technical service and parts must be available from a US vendor.

14. Vendor must supply operating and installation instructions including maintenance schedule, specifications, and part numbers for all replaceable parts, such as drive motors, screens, seals, gears, etc.

Deliverables/Schedule:

Units should be delivered during normal business hours and as soon as practical.
