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 3600 GPD/13,600 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 1800 GPD steps.

Desalination Systems with Energy Recovery



 

Vertical Mount System
1800BHL4 (2014 model)

 
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.




 

 
Self contained or semi modular concept for space saving, fast and easy self installation 
 
All control systems are electro-mechanicalNo electronic circuits close to seawater
   
Spring loaded automatic stainless steel pressure regulator – No leaking needle valves
   
Extremely silent operation – no charge/discharge noise
   
High pressure hoses with O-ring sealed stainless steel fittings – No corroding or cracking compression fittings
   
RO pressure vessels with O-ring sealed stainless steel high pressure fittings  -  No cracking NPT end plugs
   
Corrosion resistant marine aluminum frame, epoxy primed and polyurethane top coated
   
Widely available commercial size sediment pre-filters (10”x 4.5”, Big Blue) are standard equipment
 
Custom system configuration for tight installations at no extra charge
 
Five years limited warranty on the stainless steel high pressure pump
   
Post treatment pH buffer / hardener element saves up to 50% product water.    Read more...
   
No proprietary equipment  -  Consumables may be obtained anywhere (except pH buffer element)

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”, 5 and 20 microns
(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)

Product water in-line buffer element (Contains a mixture of minerals that correct product pH only enough to reach a neutral equilibrium in order to protect metal fresh water tanks and fittings. As the water is slightly re-mineralized, this will also improve the taste and makes soap rinse off easily)

or:

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)

Built-in product water buffer element (contains a mixture of minerals that correct product pH only enough to reach a neutral equilibrium in order to protect metal fresh water tanks and fittings. As the water is slightly re-mineralized, this will also improve the taste and makes soap rinse off easily)

"I have used the system for more than four years for between 10 and 24 hrs per day to supply water for normal household and building needs and finally a 15000sq. ft. garden maintenance with lawns, fruit trees and vegetable garden. My average fresh water production is 700 gallons per day, for a total of over 1 million gallons to date. The system has been very reliable. Careful attention to the regular oil change for the high pressure pump and normal consumable replacement at intervals is all that is required to maintain a high quality of product water."
