On-shore Desalination / Land Based Systems
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 makes high quality fresh water in many cases more economical than municipal water where available. The newly engineered marine aluminum frame provides tidy appearance while allowing easy access to the systems 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 back up, 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 cost.

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 sea water 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
Built-in fresh water flush system (exchanges the sea water in the RO membrane elements with freshwater and therefore avoids biological growth that may clog the elements, leading to reduced output and premature failure)
Instruments:
The desalination system is equipped with all necessary instrumentation, for the control and supervision of the operation of the unit:
Pressure Gauges: Feed water, system entrance (316SS glycerin filled, Monel tube)
Feed water, high pressure pump entrance (316SS glycerin filled, Monel tube)
RO pressure, (316SS glycerin filled, Monel tube)
Flow Meter: Product discharge
Conductivity: Digital product water quality monitor – ppm TDS
The following automatic emergency shut off functions are provided:
Low feed water pressure (e.g. seawater intake or pre-filters clogged)
High RO pressure
