STATEMENT OF WORK

1. Objective/Requirements NASA-GSFC owns and operates an active neutralization system (model PHX) from Burt Process Equipment. This equipment treats all lab waste from the Code 553 Detector Development Lab (DDL) as well as several Code 541 labs in B30, that includes waste from numerous acid and base chemical benches. These benches are an integral part of the Detector Development Laboratory, which produces semiconductor detectors for various NASA missions, such as ATHENA, Habworlds and CLASS.

Production of detectors relies heavily on wet chemical processes daily. The neutralization system is critical for the keeping these benches operational in the production of semiconductor/MEMS devices.

The current trend of science requirements is driving fabrication of detectors to larger sizes which requires larger volumes of chemistry for processing. As such, the DDL requires an upgrade to the neutralization system to handle these larger volumes. The objective is to procure parts and components to upgrade an existing neutralization system to be able to handle large volumes of chemistry as specified below.

2. Scope and Requirements

Scope The scope of this effort shall include the following to be supplied by the vendor. All parts and materials will be new and have OEM technical information if applicable.

1500 gallon double walled treatment tank of appropriate material.

Mixer motors for agitation Recirculating pumps, transfer pumps Peristaltic pump for bicarb tank pH probes Level monitoring Switches and sensors Control System for monitoring requirements Reagent injection system, minimum of (2) 70 gallon tanks, double walled (or other secondary containment) with level sensors and pumps.

Exhaust connection for reagent station Replace existing metering pump on existing PHX Ensure output pH stays within range of 6-9.

Requirements The following requirements shall be met by the vendor.

Use the existing neutralization system in combination with new hardware and controls to upgrade the system capabilities.

System power should be 208VAC.

Maintain a system effluent of pH 6-9.

Provide multiple pH monitoring points at key locations to feedback to a control and monitoring system.

Provide a control system with hardware and software capable of diverting out of spec liquid back to the treatment system.

Provide a main tank (or holding tank) large enough to perform necessary treatment of incoming chemistry and handle diverted liquid that is out of specification.

Provide a system capable of neutralizing chemistries listed in the section Chemistry Input.

Provide a system capable of neutralizing chemistries for the following conditions. Note that in standby operation there is a continuous flow of DIW at 2 GPM.

o Low flow ~2.5 GPM (residual chemistry with DIW) o High flow ~10 GPM (bulk chemistry done in batches) o pH range from 0.5 to 13.

Utilize an upstream pH monitor with controller to drive slurry tank input to main holding tank.

Lift station to be monitored for pH and if not in 6-9 range, control system will divert back to main tank.

Chemistry Input The complete upgraded system shall be capable of neutralizing incoming liquid, to the stated requirements, having the following chemical make-up and estimated volumes. These are typical and the most common chemistries and volumes and do not represent all chemicals.

Primary Residuals: The following chemicals will be sent to the system in low concentration, containing < 50mL of the chemicals, mixed with a high flow of DIW in a rinsing process.

Sulfuric H2SO4 (50%) Hydrogen Peroxide H2O2 (25-35%) Ammonium Hydroxide NH4OH (50-70%) Hydrochloric Acid HCL (20-40%)

Primary Bulk Chemistry: estimated volumes shown per item. This waste would be batched to the neutralization system at an estimated rate of once per week.
