Laboratorial scale experiments were conducted to investigate a novel system integrating catalytic ultrasound oxidation (CUO) with membrane bioreactor (CUO-MBR) on advanced treatment of biologically pretreated coal gasification wastewater. Results indicated that CUO with catalyst of FeOx/SBAC (sewage sludge based activated carbon (SBAC) which loaded Fe oxides) represented high efficiencies in eliminating TOC as well as improving the biodegradability. The integrated CUO-MBR system with low energy intensity and high frequency was more effective in eliminating COD, BOD5, TOC and reducing transmembrane pressure than either conventional MBR or ultrasound oxidation integrated MBR. The enhanced hydroxyl radical oxidation, facilitation of substrate diffusion and improvement of cell enzyme secretion were the mechanisms for CUO-MBR performance. Therefore, the integrated CUO-MBR was the promising technology for advanced treatment in engineering applications.

Advatech Designs Zero Liquid Discharge Systems As Well As Scrubbers
Advatech is a joint venture between URS and Mitsubishi. They have sold many scrubber systems in the U.S. Mitsubishi is the largest scrubber supplier world wide. They are now emphasizing their water management abilities including zero liquid discharge. Advatech Water Management: As concerns mount over the quality and quantity of our water supply, regulatory limits on water usage and discharge grow more stringent. In many instances, water usage brings with it a significant expense, and going to Zero Liquid Discharge (ZLD) is either a necessity or an expected near-term requirement. ADVATECH has designed wet FGD systems for chloride concentrations up to 50,000 ppm so that the only source of purge is the free moisture in the disposal-grade gypsum. However, this approach can incur a hefty cost in the form of materials of construction and decreased limestone reactivity. To minimize cost, we have been at the forefront in developing low-capital technologies capable of eliminating liquid discharge from wet FGD while maintaining chloride levels in a reasonable range, all this without the need for an expensive and complicated wastewater treatment process.

Controlling Water Usage and Wastewater Discharge
This article discusses ways to reduce power plant water consumption and the volume of wastewater discharged. In particular, the author says that clarification and softening of cooling tower make-up water will lead to fewer cooling tower blowdowns and improve water conservation. The article also discusses a wastewater recovery and reuse system which includes micro- or ultra-filters, an ion exchanger and a reverse osmosis system. For zero liquid discharge, an evaporator/crystallizer would also be required.

Ruediger Peldszus, Senior Manager for Applied Technology Advanced Intermediates at Evonik Degussa GmbH, backed up his claim that TMT 15® is a good choice for separating heavy metals from flue gas scrubber water by citing a large number of installations in coal-fired power plants and also waste incineration plants. When asked how the chemical impacted the gypsum quality, Ruediger explained that the resultant compound is very small and exits the top of the hydroclone and not with the gypsum through the bottom. TMT 15 can also prevent mercury re-emission from the scrubber but for this to be successful, the parameters must be carefully evaluated. One of the participants has a client who has been challenged to successfully use the TMT 15 to prevent re-emission

Michelle L. Briscoe, VP of Analytical Services at Brooks Rand Labs, observed that evaluating the effectiveness of specific FGD wastewater heavy metal removal methods requires the collection and analysis of samples for metals concentrations at each stage in the treatment process. Because of interferences, testing is showing metal concentrations which are much higher than actual. Brooks Rand Labs has developed methods to eliminate the interferences and provide accurate measurement.
