Tidally influenced surface water sources that are being treated or being considered for treatment include the Taunton River in the Massachusetts, the Hudson River in New York, the Chesapeake Bay, Tampa Bay, and the San Francisco Bay. These raw water sources can experience changes in salinity as great as 10,000 mg/l and changes in temperature of ove...

This paper will present the innovative membrane treatment plant design for the Dania Beach membrane plant that was developed to meet these challenges by maximizing system recovery while providing a developed to meet these challenges by maximizing system recovery while providing a high degree of operating flexibility. This design includes a two stag...

This paper describes work to consider design with energy recovery systems for tidally influenced surface water sources that have wide variations in TDS and temperature The overall power consumption for the two turbocharger options, the motor assisted turbocharger option and the pressure exchanger system were evaluated. This demonstrates the sens...

This paper examines a SWRO project in California and the key concerns of energy cost, source water supply and brine disposal. An innovative design using a new generation hybrid configuration of low pressure SWRO membranes and high boron rejection SWRO membranes is presented....

This paper compares brine minimization processes and examines the level of brine reduction that can be achieved, the limiting factors for brine minimization using membrane systems, and the advantages and disadvantages, operability and the relative economics of both the membrane and thermal process alternatives. Strategies for minimizing the treatme...

San Andres Island is located in the Caribbean northwest of the Colombian Coast. The northern part of the island is the center of the urban population and tourism, whereas the southern part of the island has a lower density, more rural population. The existing total water demand for the entire island is estimated around 5.14 mgd; however, the existi...
