E-MAIL: Lisa Rea-Phillips, lreaphil@ems.jsc.nasa.gov. The Government intends to issue several Requests for Offer (RFO s) in support of the development of advance life support (ALS) Environmental Control and Life Support Systems (ECLSS). The nature of the RFO s will deal with procurement of systems, subsystems and components for the development of the following technologies for future use on Mars Transit Vehicles. These procurements will be needed to support technology development and must be completed by January 1999, including the primary amount of data reduction and reports necessary to support a decision by NASA. Options may be included to provide flight hardware as early as May 2000. Carbon Dioxide Removal Systems: Sized for four to six people, the carbon dioxide removal system shall remove CO2 from the atmosphere and accumulate it for introduction into the carbon dioxide reduction system. The system design (adsorption and desorption) shall work at the most energy efficient temperature and flow rates. The system shall operate in a cyclical manner (day/night cycles) and be zero-G compatible. A vacuum pump will be required to remove the CO2 from the desorption bed to the accumulator. The vacuum pump must not contaminate the flow stream with oil or other process contaminants and must achieve vacuum pressure level of less than 0.8 torr. RFO issued 1/98; Contract Award 4/1/98; Prototype Hardware delivery 8/31/98. Carbon Dioxide Reduction Systems: Sized for four to six people, the reduction system will react CO2 and H2 from the oxygen generator system to produce methane and water. The system will require liquid coolant and a zero-G liquid/gas separator. This system must operate in a cyclical manner (day/night cycles). RFO issued 3/1/98; contract award 5/1/98; Hardware delivery 8/31/98. Trace Contaminant Control Systems: Sized for four people, the Trace Contaminant Control System (TCCS) removes trace contaminants from the cabin atmosphere. It consists of a blower, catalyst beds, a regenerative heat exchanger and an acid gas removal bed. The flowrate is 6 cubic feet per minute. RFO issued 1/98; contract award 4/1/98; Hardware delivery 9/98. Biological Water Recovery Systems: Biological Water Processor Design must be microgravity compatible. The system must reduce influent TOC (total organic carbon) to less than 20 mg/l and achieve a minimum 50% nitrification. De-nitrification should be accomplished to the greatest extent possible. Water source shall consist of shower water, handwash water, urine, humidity condensate, and oral hygiene waste water from four to six people. Daily volume shall be 30 liters, average influent TOC 1000 mg/l, average influent NH4+ 1000 mg/l, and the soap shall be Ecolab 6503.45-4. Typical system package shall include all components necessary to integrate into a water recovery system (pumps, heaters, etc.). Instrumentation shall include inlet and outlet pH, inlet and outlet conductivity, system temperature and flowrate. RFO issued 1/98; contract award 4/1/98; Hardware delivery 9/15/98. Inorganic Effluent Removal System from Biological Water Processor (secondary treatment)Design must be compatible with operation in microgravity, with all components included in the package (for example, if a gas/liguid separator or two-phase pump is required for microgravity operation, they are to be included in the package) System must be capable of processing water continuously at an average flowrate of 20 ml/min. The system should not be operated as a batch processor. System must achieve 100% recovery of wastewater. More than one subsystem may be integrated to achieve 100% recovery. System must reduce influent inorganic salt concentrations to meet NASA potability requirements; however, up to 20 mg/l ammonium may remain in the product water. Critical maximum contaminant levels include: NO3- < 10 ppm (as N) and NO2- < 1 ppm (as N). Feed wastewater stream shall consist of: Wastewater sources: Biological water processor effluent Daily volume to treat: 30 liters; Average influent TOC: 10 mg/l; Average influent conductivity: 4 mS; Average influent NH4+: 100 mg/l;Average influent Na+: 400 mg/l; Average influent Cl-: 400 mg/l; Delivered system package should include all components required to integrate into a water recovery system (for example: feed pump, heaters). Delivered system should be instrumented as necessary. Instrumentation shall include inlet and outlet pH, inlet and outlet conductivity, system temperature, and flowrate. System shall be compatible with GE Fanuc PLC. Sample ports must be provided in the system As-built mechanical and electrical drawings must be provided with the system A hazard analysis and failure modes and effects analysis must be provided with the system. Consumables required for system operation should be minimized. RFO issued 1/21/98; contract award 4/1/98; Hardware delivery 9/15/98. Post Processing (water polisher) Design must be compatible with operation in microgravity, with all components included in the package (for example, if a gas/liguid separator or two-phase pump is required for microgravity operation, they are to be included in the package) System must be capable of processing water continuously at an average flowrate of 20 ml/min. The system should not be operated as a batch processor. System must achieve 100% recovery of wastewater System must reduce influent organic carbon concentrations to less than 250 ppb.
