Mission and Goals

The vision of CIDS is to become a premier research group recognized internationally for excellence in inland desalination education, research, service and technology commercialization.

Funders and Collaborators

CIDS builds on a strong foundation of related research already being done by faculty members in geological sciences, chemistry, and civil engineering. CIDS was formed using a combination of a $2 million grant from the state of Texas through its Emerging Technology Fund and a $2 million grant from the University of Texas system. In addition, CIDS researchers have received funding from a variety of sources including the Bureau of Reclamation, the Environmental Protection Agency, El Paso Water Utilities, and private industry.

EXPERTISE

CIDS researchers are primarily focused on inland desalination issues such as researching and developing high recovery desalination processes and recovering useful products from desalination waste streams.
Energy-Water Nexus: Produced water treatment using conventional and novel processes, Treatment for extracted water applications to energy and carbon sequestration.
Policy and Small Communities Assistance: POU water treatment for improving sustainability and environmental justice in colonias of the Paso del Norte region, Practical alternatives to pilot plant studies for innovative water technologies, Desalination Concentrate Management policy Analysis for the Arid West.
Maximizing Inland Desalination Efficiencies (minimizing waste): Zero Discharge Desalination (ZDD), a form of zero liquid discharge, Recovery of sodium sulfate, sodium chloride and other useful salts or metals from brackish water, High-volume water recovery from silica-saturated RO concentrate.
Contaminant Removal & Resource Recovery: Desalination processes like RO tend to remove all contaminants from the water at about the same rate. However, often there is a need to remove special contaminants such as arsenic and ammonia without removing other less objectionable materials from the water. The CIDS group has expertise in the use of special adsorbents for the removal of low-level contaminants from water. CIDS also has expertise in the recovery of regenerant salts from ion-exchange resins used in the removal of contaminants from water.

CAPABILITIES

ELECTRODIALYSIS SYSTEMS
Electrodialysis (ED) is an electrically driven membrane process that can remove salt from dilute solutions and raise the concentration to levels no attainable by RO. CIDS has strong capabilities in ED technology unmatched by any other university in the USA. CIDS researchers work on the cutting edge of novel applications for ED. CIDS owns several laboratory (0.25-2 gallon per minute) and pilot sized (20-40 gallon per minute) ED systems, which are available for collaborative research or lease.

PRESSURE-DRIVEN MEMBRANE SYSTEMS (reverse osmosis and nanofiltration)
Reverse osmosis (RO) and nanofiltration (NF) utilize a membrane that is permeable to water but substantially impermeable to salt. Pressure applied to the salty water must overcome the natural osmotic forces that would transport water from the dilute to the concentrated salt solution. CIDS owns several pilot plants that allow demonstration of RO and NF at flow rates up to 40 gallons per minute.

LABORATORY TESTING & WATER QUALITY ANALYSIS

  • Engineering: CIDS has two laboratories (1600 square feet) used to research membrane-based and adsorption-based water treatment techniques and perform water quality analyses for research projects. One lab is used as a wet laboratory and currently includes two laboratory electrodialysis systems, and ultrafiltration system, and several salt recovery/contaminant removal systems. The other laboratory houses CIDS’ analytical equipment including: two ion chromatographs, an inductively coupled plasma optical emission spectrometer, a total organic carbon analyzer, a gas chromatograph, an ultraviolet-visible spectrophotometer, a crystallizer, and general analytical capabilities (pH, conductivity, TDS, TSS, colorimetric methods).
  • Burges Hall: CIDS has two laboratories (1400 square feet) used to research novel membrane-based treatment techniques such as membrane distillation, diffusion dialysis, and development of graphene-based membranes. A Beckman Coulter Multisizer™ 4 particle size analyzer allows CIDS researchers to quantitatively study suspended particles in water samples between 0.6-240 microns in size.
