We have a pilot-scale water treatment facility with a maximum treatment capacity of 9 gallons per min (= 34 L per min), three 3,000-gallon (= 11,000 L) raw water storage tanks, and programmable logic controller (PLC) and supervisory control and data acquisition (SCADA) capabilities in our warehouse. The pilot facility is flexible and may be configured to include any combinations of the following unit processes in any desired order:
- Biological treatment (aerobic and anaerobic)
- Chemical oxidation (e.g., chlorine, ozone, permanganate, and hydrogen peroxide)
- Media filtration (e.g., silica sands and reactive media)
- Ion exchange (weak base, strong base, weak acid, and weak base)
- Nanofiltration or reverse osmosis
- UV disinfection and UV-peroxide AOP
There are sampling ports after each unit processes, as well as online monitors for pH, pressure, flow rate, and conductivity with a data logger.
Water Chemistry Lab
We have a fully-equipped water (wet) chemistry lab adjacent to the pilot lab where samples from our pilot plant or the fields are processed and analyzed. We can analyze more than 30 different parameters in our lab. If necessary, additional chemical analysis may be done in a commercial analytical lab or in one of our collaborative partners’ labs. In addition, we can perform bench-scale tests to simulate various unit processes in the wet chemistry lab. For example, bench-scale ozone tests are done to determine key design parameters, such as ozone dose and contact time.
