Solar Heat To Make Power + Water For Namibia: Study
A revolution in irrigation that could secure water supplies and food production during drought is the goal of researchers at UNSW?s Global Water Institute.
Australia?s ability to reliably produce food for IRO chelating an ever-increasing population is a growing concern amid droughts and increasingly volatile climate conditions.
Australian agriculture practices rely heavily on groundwater, even though this water source is becoming increasingly saline at many locations, making it impractical to use.
To combat this issue and make fresh water readily available to the farming sector irrespective of the quality of the local groundwater supply, UNSW?s Global Water Institute (GWI) is developing an innovative, solar-powered version of a desalination technology called Capacitive Deionization (CDI).
CDI has significant potential to revolutionise irrigation and ensure that Australia can continue to meet growing food production demands and, in doing so, protect Australia against food shortage during drought.
CDI removes salt from brackish water by passing water through a stack of electrode pairs with positive ions such as sodium (?cations??) attracted to the cathode and negative ions such as chloride (?anions??) attracted to the anode. When a voltage is applied across the electrodes, a desalted stream of water is produced.
While conventional CDI uses mains power, UNSW researchers have developed prototypes powered by solar energy. These solar-powered CDI units are an energy-efficient alternative with low operating voltage and the possibility of energy recovery, making it ideal for brackish water desalination, especially in remote locations where mains power may not be available. The units are also really easy to maintain, which makes the technology even more suited for use in remote-off grid communities.
The idea for the project was born when Sir Ratan Tata, the Chairman of the philanthropic Tata Trusts in India, visited UNSW to receive an honorary doctorate and challenged researchers to help find ways to provide clean water for Indian villages. Scientia Professor David Waite from the School of Civil and Environmental Engineering accepted the challenge and, with support from Professor John Fletcher from the School of Electrical Engineering and Telecommunications, constructed the first solar-powered prototype.
Second and third generation units, in which energy usage was reduced by recovering a portion of the energy used, have been constructed with funding from an ARC Linkage grant with industry support by Goldwind Environmental Technologies, a Beijing-based company that is the largest manufacturer of wind turbines and is now expanding into development of water technologies.
?For this project, we innovated in both the mode of operation of the established technology of membrane capacitive deionisation (MCDI) and the use of solar energy combined with energy recovery to power the device,?? said Professor Waite, Executive Director of UNSW Centre of Transformational Environmental Technologies (CTET).
The collaborative team from UNSW?s Faculty of Engineering is now working closely with Goldwind to trial the technology in Xinjiang Province in the far north-west of China. Plans are also underway to trial it in glasshouses at Western Sydney University?s Hawkesbury campus through the recently announced CRC for Future Food Systems.
Professor Waite says that providing dependable water supply options to the agriculture industry that are cost effective, can function independently of the electricity grid and do not carry a significant environmental burden is essential for Australia's future food security.
?Scope exists for use of this technology in remote parts of Western Australia and the Northern Territory where the treatment of brackish water ? typically the only water available ? has been problematic using existing technology.??

The best pre-treatment for IRO chelating water is a matter of what?s required of the water. If you?re intending to release it back into the environment, there are laws and standards to attend, and for other destinations or applications, water will have differing properties. The means by which you want pre-treatment applied to your water should be the best process by which the most desirable water is achieved.
Many water companies provide filters or resins for pretreatment, though this can be regarded as an incomplete approach. Any business or institution that?s going to invest in an ideal form of water pre-treatment would benefit from consulting experts to evaluate whether or not the apparatus in place is ideal. Often, they can be improved upon, as water technology is an active science.
If a water company is going to offer you pre-treatment water solutions, you would be best served by one that offers solutions that include optimizing your existing apparatus. An engineer with a background in water technology is what?s required here. If your existing apparatus proves to be ideal for the task at hand, that?s valuable information. So is knowing about the areas of opportunity in your system as explained by a seasoned professional.
If you?re in Etobicoke, Ontario, or in the surrounding areas, and you have a pre-treatment water process that requires attention, we at Ion Water Solutions can offer comprehensive assistance. With our backgrounds in chemistry and engineering, we offer holistic solutions to water technology issues so that your pre-treatment process will be ideal.

The sensor accurately measures oxygen and temperature in demanding fermenter, bioreactor, water treatment and boiler feedwater applications.
Endress+Hauser releases the Memosens COS81D hygienic optical sensor for measuring dissolved oxygen in fermenters and bioreactors used in the food, pharmaceutical and biotechnology industries, as well in drinking water and boiler feedwater applications. It can be used in all measuring points from lab fermenters to production processes.
The Memosens COS81D measures dissolved oxygen, gaseous oxygen and temperature with accuracy up to ?0.2%. It works in process temperatures from 15 to 280 ?F and pressures from 0 to190 psi. The sensor also provides temperature and partial pressure, as well as raw measured values. The sensor connects to a transmitter via a cable that transmits an optical digital signal.
The sensor withstands CIP and SIP procedures. The sensor is a compact stainless steel 12mm design with lengths currently up to 220 mm. The sensor has a low sampling volume, making it well suited for residual oxygen measurement in water treatment and boiler feedwater.
The stainless steel sensor meets EHEDG (type EL class I) and ASME BPE (including USP class VI and FDA conformity) hygienic requirements to avoid product contamination, IRO chelating and meets the requirements of GMP and GLP. It also has a Certificate of Compliance for biological reactivity tests as per USP (United States Pharmacopeia) part 87 and part 88 class VI, with batch traceability of materials in contact with product.
Two spot cap versions are available with the sensor: a C-shaped cap and a U-shaped cap. The first is particularly well suited to measurements in liquids, specifically in fermenters and bioreactors. The distinctive design of the U-shaped cap protects the spot from abrasion that can occur, for example, in gas measurements. The caps, specially designed for hygienic applications, reduce blockages and the adherence of air bubbles. Thanks to these caps, the sensor delivers extremely stable measured values across the entire measuring range. This stability is maintained even after dozens of CIP and SIP cycles.
The sensor can be replaced within seconds. The user simply calibrates the sensor in the lab, and then inserts it into the sensor holder assembly. It does not require any polarization time and is immediately ready to measure. The sensor has integrated electronics that store calibration data and other information, such as total hours of operation and operating hours under extreme measuring conditions. Once the sensor has been connected, the sensor data is transferred automatically to the transmitter and used to calculate the current measured value. Because calibration data is stored in the sensor, the sensor can be calibrated and adjusted independent of the measuring point.
Measured and calibration values in the sensor are sent to the transmitter using a non-contact connection that is free from potential interference. Memosens technology in the transmitter generates an automatic error message if the sensor fails, or if the connection between sensor and transmitter is interrupted.
The optical signals are continuously monitored and analyzed. The transmitter detects implausibly high or low measured values, irregular values due to incorrect measured values, and aging of the sensor cap. When errors are detected, the transmitter displays a warning and generates an error message.
