APPENDIX D

AGENDA FOR VENDOR INTERVIEWS

Restatement of Goals & Objectives (by Tech ID Subgroup)

  • Obtain/clarify submitted information

  • Ensure Vendor’s understanding of TECH ID Subgroup’s purpose in the completion of Bench Scale Testing (BST) and what resources will be required by the Vendor.

  • Obtain Vendor’s commitment

  • Explain time line

Detailed questions to be Answered\Information to be Collected during the Interview:

1. Technical Aspects of the Technology

Flow rate/hydraulic capacities Types of wastewater treated
Influent/effluent concentrations Schematics of the system(s)
Known interferences Mechanism of removal

Case studies

2.  Vendor to make detailed presentation which highlights the elements of his technology (Vendor to identify audio-visual requirements in advance of the interview)

3.  Vendor to identify the species of mercury that can be removed (ionic, complexed, particulate, etc.) using his technology.

4.  Normal Vendor BST requirements (provide equipment list, schematics, protocols). Recommended type of BST: dynamic system (column tests) with pretreatment options or static "jar" tests. Pilot scale and full scale system scale up considerations.

5.  Vendor experience with mercury removal from hospital waste streams (i.e., clinical laboratories, research laboratories, hospital incinerator scrubbers, and hospital laundries). Needed pretreatment steps (flow and concentration equalization, filtration, pH adjustment, organics removal, disinfection, etc.) for optimal performance. For adsorptive media, discussion and supporting breakthrough curves for media capacity and expected loading (milligram Hg per gram of media) at 1 ug/L effluent.

6.  What is approximate cost per gallon of your technology based upon existing applications? What is the mercury concentration range of these applications?

Ground rules:

Vendors will be allowed up to 45 minutes to make their presentations followed by a 15 minute

Q&A period by members of the Tech ID Subgroup. These members include representatives from the State OTA, MWRA and the Hospital sector that are professionally licensed and holding advanced engineering degrees (MS, PhD). Therefore, Vendors should be prepared to answer fairly technical questions during the Q&A period. Total Vendor presentation will not exceed one hour.

No Vendors will be allowed in the room while another Vendor is making a presentation. This will be done in an effort to help ensure that sensitive or proprietary information is not divulged by a Vendor to a potential competitor.
