Reverse Osmosis Watermakers and Systems

Reverse Osmosis Watermaker Systems and Solutions from Monitor Systems Engineering meet the most demanding applications in harsh environments.

Reverse Osmosis Watermaker Desalination Systems for Offshore Applications

Monitor Systems Engineering builds a range of Reverse Osmosis (RO) watermaker systems to meet the wide variety of demands of the offshore drilling and production industry. Each packaged system is designed and built for simple operation and ease of maintenance. The system components have been selected, developed, or and optimized for use in the offshore environment.

Monitor Systems Engineering produces both standard and custom Reverse Osmosis Watermaker Systems.

Our world-wide reputation as the premier supplier of potable water RO Watermakers to offshore oil & gas production facilities is founded on the standard ''FD'' Series Watermakers. Potable water RO Watermakers from Monitor Systems Engineering can provide water production at rates from 4 to 100 m3/day.

Custom Reverse Osmosis Watermaker solutions from Monitor Systems Engineering have been designed to produce many other kinds of water including: Boiler Feed, Turbine Wash, Battery top-up, and the higher capacity demands of Crude desalting, and Well Injection.

FD Series Reverse Osmosis Watermaker Design Features

• Four stages of graded mechanical filtration, including:
- 3 x 50%, activated carbon, media filters, automatically backwashed with the reject brine and with no interruption to fresh water production.
- Three more stages of bag and cartridge filtration to 1/2 µ
• The Series 20, single-stage centrifugal, RO pump with over 30 years of operation in the offshore environment. A pump with no vibration and quick and easy to repair offshore.
• The Type 200-SWHR permeators with one membrane element per housing; sample valve, vent seals; by-pass shunt; quick access end cap; galvanically protected 316L and Nitronics® construction.
• Net Osmotic Pressure Controller (NOPC) for membrane flux control.
• Brine pressure let-down tubing for RO pump flow & pressure control.
• Rugged steel frames with high quality epoxy coatings
• Corrosion resistant and durable components
• Compact footprint
• Highest levels of filtration in the industry
• Simple, reliable, and most economical system

Because the offshore marine environment is so severe, reliability depends on systems which can withstand the test of time. For twenty years Monitor Systems Engineering equipment has been providing dependable fresh water for drinking, equipment wash-down, general utility, desalting crude, and other processes. Monitor Systems Engineering has been rejecting unreliable components and integrating only field proven components into standard designs. This sustained work over many years has resulted in highly reliable, economical Reverse Osmosis desalination plants for offshore marine installations.

Steel-Cage Frame Construction

Potentially the most destructive forces on a watermaker occur as it is shipped and moved into place, and when it is damaged by other on board equipment, such as a crane or forklift. Monitor Systems Engineering’s steel cage construction protects the components from this sort of unpredictable damage.

Shippers have dropped heavy skids on top of our units in the past, but the rugged, steel cages enclosing the components have allowed the equipment to suffer only minor damage and go on to operate successfully with little or no repairs needed.

Media Filters

Monitor Systems approach to media filtration takes unique advantage of the conditions of the Reverse Osmosis process offshore. Special media, backwashed by super filtered seawater, make these filters high performance; they remove all influent chlorine and most particles down to 25 micrometers.

The filters are completely automated and run in both service and backwash modes while the desalination system is producing fresh water.

Type 200-SW Permeators

From experience, we’ve learned that when membrane cartridges require servicing, the operator needs to have a simple way of detecting and then servicing the correct membrane cartridge.

With this in mind we developed the Type 200-SW permeator, which houses a single spiral wound membrane cartridge within a 316 stainless steel shell. The high pressure ports in the housing are away from the ends, allowing the operator easy access to the membrane cartridge within. Each end contains a Monitor Systems Engineering vent-seal, which tells the operator if any cartridge has developed a seal leak.

Flow Regulation

We have taken advantage of the natural hydraulic characteristics of the Series 20 Pump/Reverse Osmosis membrane combination and simplified the controls to the point where there are no valves to adjust.

From the moment of start up the system regulates its own product flow to the exact design rate, thereby extending the life of the membranes and providing a constant, reliable fresh water stream without operator intervention.

Graded Mechanical Filters

We long ago discovered that the secret to extending the useful life of Reverse Osmosis membranes is to filter the feedwater as finely as practically possible.

Fine filtration, economically achieved, has been a primary goal in Monitor Systems Engineering system development. Through extensive field testing we learned how to filter seawater down to 0.5 micrometer economically, thereby delivering essentially particle free water to the membranes downstream.

These improvements have resulted in longer, trouble free membrane life with no chemicals required for operation.

Series 20 Pump

C'treat have been evolving this pump ever since 1980, and they are still working to make it even more dependable.

The Series 20 seawater pump is the workhorse of over 250 systems, providing the approximately 1,000 psig required to push fresh water through the membranes.

Because the pump is single stage centrifugal, its moving parts can be carried in a brief case; servicing is quick, and major repairs can be made in 30 minutes.
