This presentation discusses recent improvements in ro membrane performance, including specific flux, salt passage, and active area per unit. It also discusses the application of these improvements to reduce membrane cost and pressure requirements. Examples are given where these have been accomplished....

This presentation describes the decision making behind the decision to install onsite hypochlorite generation instead of purchasing bulk hypochlorite. Costs are provided together with a description of the water treatment facilities....

This presentation discusses the value of piloting not only to gather design data for the RO, but also to examine the optimization of chemical usage to minimize cost without impacting the mission....

This presentation presents a discussion of the use of variable frquency electric motor drives to save energy in municipal water and wastewater treatment plants. Some examples are given of savings in wastewater treatment, for pumping and aeration....

This presentation describes the water system in the Florida Keys; Florida keys Aqueduct Authority; shallow aquifer treatment by lime softening; bracckish water Ro for additional supply; seawater RO for emergency supply; long high pressure distribution system....

This presentation describes the need for benchmarking electrical energy usage in an RO plant; describes how to set up a spreadsheet, and populate it with the information needed. Also considers similar approach for other cost centers in the plant....

This presentation provides a comparison between methods of reducing power consumption in an existing brackish water RO plant by utilizing energy recovery devices. Three options are examined, and a comparison of pumping horsepower and permeate quality is given....

This presentation describes the hydrogeology of the Floridan aquifer; the variations with depth and thickness; the use of modelling to control and predict the natural increases in TDS due to horizontal and vertical leakance; design of wellfield to sustain well production and quality....

This presentation describes the retrofit of an existing high TDS brackish water RO plant designed and installed without interstage boost/energy recovery. A discussion of options is given, and limitations due to pipe pressure rating are discussed....

This presentation describes the various aspects of the Coquina Coast desalination project that was considered for Northeast Florida...

This PowerPoint presentation discusses the evaluation of concentrate disposal alternatives and Zero Liquid Discharge evaluation along with the pilot study that confirmed treatability, feasibility, and economics as favorable for Palm Coast Florida membrane treatment plants...
