高能耗和高投资一直是阻碍反渗透海水淡化技术大范围推广应用的主要原因.为了促进反渗透海水淡化技术尤其是中小型反渗透海水淡化装置的推广应用,文章就一种10t/d高效节能反渗透海水淡化装置进行了中试试验研究.由于采用了新研制的差动式能量回收装置,中试装置产出每吨淡水高压能耗只有3.6kWh,不考虑高压泵及电机自身损耗的影响时每吨淡水能耗为2.3kWh~2.7kWh,装置能耗得到显著降低,余压能量回收效率达到97%.装置产水流量稳定,产水质量较好,电导率可达290μS/cm. 相似文献

ABSTRACT: An industrial mussel cooking juice was treated by a 3-step process to produce a natural aroma concentrate and a cleaned water stream. The juice was centrifuged before being desalinated by electrodialysis and then concentrated by reverse osmosis. As a result of this combined process, most of the physicochemical properties of the reverse osmosis permeate were reduced below the discharge standards. The concentrate was examined by a trained sensory panel (triangular tests, sensory profiles) and by gas chromatography/mass spectrometry. The sensory profile of the concentrate was shown as slightly different from the unprocessed mussel cooking juice one. Nevertheless, the concentration process preserved the native characteristic aroma of the cooked mussel, of interest to human or pet food industries. 相似文献
