At AqSep, we offer two product series of watermakers: the WM-E and the WM-B Series. Any product in the two product series can form the heart of a turnkey solution provided by one of our partners. As both series consist of a wide range of efficient and reliable desalination units, you can rest assured that we have the perfect solution to meet your specific requirements. All watermakers are available with GSM modules enabling remote control and monitoring via mobile phone.

The WM-E Series operates fully automatically and is equipped with one of the world’s most efficient and robust energy recovery systems for small-scale desalination units. Energy recovery is a technique that minimizes the amount of energy used to produce fresh water. This energy-efficient technique reduces running costs by as much as 70 %.
The WM-B Series will occasionally require manual control of membrane pressure, and these desalination units operate without energy recovery systems. However, the watermakers are still of extremely high quality and used where energy costs are low.
Desalination units purify salt/sea or brackish water into high quality drinking water using the Reverse Osmosis (RO) process. Salt water RO is a separation process, using high pressure to force salt/sea water through a membrane that retains all salts and other dissolved and suspended matters on one side and allows only pure water to pass to the other side without the use of chemicals of any kind.
The RO method has been known and recognised for many years and is commonly used in desalination plants for public water supply, in hotels, hospitals and on ships.
Our watermakers can mainly be used in coastal areas and on islands where normal sources of fresh water are limited and/or of bad quality. The unit is not only suited for private homeowners but can also be used in hospitals and health clinics and for remote communities. It is also ideal for commercial use such as in small hotels, restaurants, camper parks, marinas, yacht clubs, island settlements and resorts etc.
Watermakers can also be used as a primary source or as a back-up for the provision of drinking water to police and military facilities, to public institutions in coastal areas or on islands. If you need more water than 22,000 liters per day (5,812 gallons) for the E-series or 18,700 liters (4,940 gallons) per day for the B-series, you can install more units in parallel.
The WM11000E can produce 11,000 liters (2,906 gallons) of drinking water per day (24 hours). A typical consumption of less than 1.5 kW power when desalinating normal sea water is possible. This brings the typical energy consumption down to about 3 kWh per 1,000 liters at 35,000 mg/l TDS (25 °C). This is significantly below the level of most other desalination units of this capacity.
The cost of production of water depends on which watermaker model you choose, the price of electricity, the degree of product utilisation, the cost of labour and the expenses for filters, spare parts and membrane cleaning and replacement. It may be assumed that for the WM-E Series, the total production costs can be as low as US$ 5-6 per 1,000 gallons or 1 Euro per 1,000 liters).
