On-shore Desalination – up to 10,000 GPD/37,900 LPD

The BHL Series has been especially designed for small Hotels, Marinas and Waterfront Homes with access to salt or brackish water and where supplying clean water can be logistically complex and expensive. The high power efficiency, ultimate reliability, and low maintenance cost of these desalination systems make high-quality fresh water in many cases more economical than municipal water where available. The newly engineered marine aluminum frame provides a tidy appearance while allowing easy access to the system’s components for maintenance. The modular wall mount systems or the self-contained vertical framed systems are space-saving and almost turnkey so that people without engineering backgrounds can install them. For freshwater capacities of a multiple of 7.000 GPD / 26,495 Liters, the installation of any number of redundant operative BHL desalination modules can produce unlimited output.

More economical than a single large system, multiple desalination modules provide backup, ease transport as well as installation, and reduce the electrical start-up load by more than 35%.

In times of low water demand, only the modules needed are operated for low maintenance and ultimate cost efficiency.

Upgrades are easy, fast, and available in 1.800 and 7,000 GPD steps.

If a seawater well/spear/bore or open seawater intake at a lower water level is used, the installation of a submersible feed pump is recommended. A sand filter (multi-media filter) installed before the cartridge pre-filters can reduce filtration costs.

Reverse Osmosis performance varies with the feed water temperature and salinity.
The rated performance is tested at 26ºC / 80ºF water temperature and ^{salinity of 35000 ppm TDS.
*Also available in 36 VDC, 48 VDC, 90-96 VDC, and 180 VDC
**Prices shown do not include shipping, taxes, and/or customs duties (if applicable)}

Scope of Components

Wall mount frame (marine grade aluminum 6061) with shock-mounted stainless steel high-pressure pump and electrical/flow control panels.

1 Pressure vessel rack with 1-4 thin film composite RO membranes

1 Pre-filtration rack with standard size BB cartridges, 4½” x 10”,
(except systems 400/700-BHL: 2½” x 10”, 5 and 20 microns)

Fresh water flush system (Exchanges the seawater in the RO membrane elements with freshwater and therefore avoids biological growth that may clog the elements, leading to reduced output and premature failure)

or:

Vertical mount frame (marine grade aluminum 6061) with shock-mounted stainless steel high-pressure pump unit, electrical/flow control panels, and RO vessels

Built-in dual filter housings with pleated polyester standard size BB cartridges, 4½” x 10”, 5 and 20 microns
