摘要： An apparatus includes a filtration skid configured to generate a filtrate through at least one of microfiltration and ultrafiltration. The apparatus further includes a desalination skid fluidly connected to the filtration skid. The desalination skid is configured to perform reverse osmosis desalination on the filtrate to generate a permeate, where the filtrate travels from the filtration skid to the desalination skid without traversing a storage tank. In one embodiment, the apparatus further comprises a controller, where the filtration skid and the desalination skid are integrated to provide self-adaptive operation of the filtration skid and the desalination skid in response to control by at least one of a supervisory controller and a local controller. In one embodiment, the control responds to at least one of temporal variability of feed water quality, a permeate production capacity target, and a permeate quality target.

摘要： An economical and commercially practical reverse-osmosis water purifier system which has no back pressure acting against the semipermeable membrane, so that the filtering rate is maximized. Furthermore, the supply of tap water to the system is shut off automatically as soon as the pure water storage tank is full, use of water thus being greatly reduced. These, and other major advantages, are achieved despite the fact that there is only a single tube extending to the faucet, automatic ice-maker, refrigerated drinking fountain or other point of use.The system uses rugged, long-lasting and economical diaphragm valves, which eliminates the need for sliding seals. Thus, it becomes highly practical to injection-mold the valves of plastic.The long-standing major problem of plugging or fouling of the constricted outlet for waste water is eliminated at low cost and with very little use of water. What water is used provides not only cleaning of the constriction region but also a partial flushing of the filter membrane. These results are achieved by means of a self-cleaning constrictor valve having a predetermined flow area which may be made as small as the manufacturer desires.In one embodiment, a valve is provided to automatically stop the outflow of squeeze water while the faucet is in open condition. This saves additional water and also makes it possible to build up a relatively high pure-water pressure even when the inlet pressure is less than average.
摘要翻译：一种经济且商业上实用的反渗透净水器系统，其无反压力作用于半透膜，从而使过滤速率最大化。此外，一旦纯净水储存罐充满，系统自来水的供应便会自动关闭，从而大大减少了使用水量。尽管事实上只有一根管延伸到水龙头，自动制冰机，冷藏饮水机或其他使用点上，但是这些和其他主要的优点是实现的。该系统采用坚固耐用，经久耐用的隔膜阀，无需滑动密封。因此，注塑塑料阀门变得非常实用。废水的收缩出口堵塞或堵塞的长期存在的主要问题是以低成本且少量使用水被消除。使用什么水不仅提供收缩区域的清洁，而且还可以部分地冲洗过滤膜。这些结果通过具有预定流动面积的自清洁压缩阀来实现，该预定的流动区域可以制造得像制造商所希望的那样小。在一个实施例中，阀被设置成在水龙头处于打开状态时自动停止挤压水的流出。这节省了额外的水，并且即使当入口压力小于平均值时，也可以建立相对较高的纯水压力。

摘要： This disclosure examines using alginate lyase to catalytically degrade alginate in order to decrease affinity and fouling potential to membranes of 0.2 and 0.02 μm pore size, respectively within a process line of a filtration system. Enzymatically treated alginate caused less fouling on both ultrafiltration and microfiltration membranes than original alginate. Enzymatically treated alginate is predicted to cause less fouling on both membranes within the pH range of approximately 3.0 to approximately 10.0. Without the presence of calcium cation, alginate lyase reduced the foulant resistance by more than 82% for both membranes. In the presence of 1 mM calcium cation, alginate lyase reduced the foulant resistance by more than 55%. In addition, the foulant structure composed of enzymatically treated alginate was more readily removed by backwashing, suggesting reversible fouling. The advantages of using enzymatic technique to control membrane fouling include high efficiency and no damage to the membrane materials.
