为了满足科利尔县未来的需求，设计了一座膜处理厂，该厂能够处理多种不同的水源，以满足新的用水需求。虽然初始资本成本高于石灰软化，但膜处理的好处包括更好的饮用水质量（远远超过颁布的联邦和州标准）和更长的设施寿命，因为它能够同时处理不同质量的水和多种水源。这一点很重要，因为该县希望能够利用现有井场的额外水资源，而不会像石灰软化处理那样限制设施的未来利用。 该设施可同时处理淡水和盐水，使用设计在工厂内的分体式管道系统。将来，只需更换膜并添加一个泵级，即可实现向全反渗透处理的转化。这一设计背后的理念是利用当前的膜技术解决未来法规变化、水源变化、水质变化和操作灵活性的问题。

To meet future demands in Collier County, a membrane treatment plant was designed that would be capable of treating multiple and changing sources of water to meet new water demands. While higher in initial capital costs than lime softening, the benefits of membrane treatment include better potable water quality (exceeding promulgated Federal and State standards by a considerable margin) and longer life of the facility because of its ability to treat different quality waters and multiple sources at one time. This is important because the County wanted to be able to take advantage of additional water availability in the existing wellfield, without limiting future utilization of the facility as would lime softening treatment. This facility can treat both freshwater and saline water at the same time using divided piping systems designed into the plant. Conversion to full reverse osmosis treatment in the future can be accomplished by simply changing the membranes and adding a pump stage. The concept behind this design addresses use of current membrane technology for solving future changes in regulations, changing water sources, changing water quality and flexibility in operations.
