Easy reverse osmosis.
Avoid high energy bills. Easy & efficient watermaker.

Desalination doesn’t have to be energy intensive or complex to maintain. Our durable and efficient reverse osmosis units are powered by your energy supply. Get access to clean and reliable water using our easy to operate watermakers for land-based applications for private islands, resorts, communities, private properties, industries, hotels and others. The watermaker was developed with a philosophy of quality, durability, efficiency and comfort. We offer the following advantages over conventional reverse osmosis:

  • Consume 3-4x less energy with maintenance-free energy recovery.
  • Water quality assured by constant monitoring & automatic stop.
  • Easily make water by remote monitoring, control & automation.
  • Avoid frequent RO membrane replacement by automatic fresh flush.
  • Durability & resistance to corrosion ensured as all wetted parts are duplex or super duplex steel and the frame is HDPE.
  • Simply operate the reverse osmosis unit with a single button interface that provides access to production data & product water TDS.

Benefit from the globally implemented desalination systems that enables reverse osmosis using only 1.0 kW to desalinate 11 m³ or 2900 gallons per day. With a lead time of only a few weeks, these compact watermakers can be quickly deployed to ensure clean and reliable water on-site. Take a look below at the limited footprint and weight, references, components and a financial comparison with conventional watermakers.

How our efficient desalination technology works:

Compact low-energy desalination.

The compact solutions can be designed for any requested water production, below are some examples. Different power and voltage options available. We also provide containerized units for plug and play installation, or integrate all separate components to your preference into the (existing) infrastructure.

”A special thanks to Elemental Water Makers who joined forces with Lanzarote Retreats to achieve their sustainability goals. The Dutch team made it possible for our eco-village to become independent on water. We are naturally powering the desalination unit by harnessing the wind & sun.

I hope Elemental Water Makers will continue to encourage the rest of the world to do the same.”

Time-tested components.

Compact RO with low energy consumption. Take a look how we ensure a minimum of maintenance and stress-free operation.

Most pumps have to be replaced yearly when used in salt water. We believe in quality and reliability and work with efficient variable frequency pumps who can withstand (which are suitable for) warm seawater applications, such as titanium or 904L pumps.

To avoid frequent membrane replacement, the pre-treatment will be designed for your site-specific situation. This can involve sand filtration, cartridge filtration and more.

Stress-free operation is ensured by remote monitoring, control and automation. To avoid frequent replacement, the membranes are automatically flushed with fresh water at every shut-down.

High-efficiency desalination (< 3 kWh/m³) is enabled by re-using the brine pressure, even for small-scale production. The maintenance-free energy recovery systems are constructed from (super) duplex steel.

To meet your specific applications, we can add fresh water treatment steps to the system, for example, remineralisation, UV treatment before end use or preservation dosing to make it suitable for longer term storage.

We can include high corrosive resistant modular tanks with bladder liner that can easily be shipped on a pallet and constructed on-site, requiring only a ring of tiles, instead of an entire concrete foundation.

HDPE pipe is our preferred material for long distance pipe sections as it’s able to withstand high pressures, salt water, offers flexibility to be placed in bends and withstands forces from outside. The pipe materials can both be sourced locally or shipped in.

The units are equipped with GSM-based monitoring for remote control and alarm messaging. Check in on your water supply, anywhere, anytime.

Financial case: efficient RO using local energy.
A private island enjoying guilt-free water thanks to an efficient watermaker.

The problem: no fresh water available at acceptable expenses
The private island has a water demand of 9 m³/day due to landscaping and private use. The rain is not reliable and sufficient enough, leaving no alternative for desalination. Two options are available, which first appears to be an easy decision as the standard reverse osmosis solution is about 30% cheaper in the purchase price.

The solution: efficient RO unit
Fortunately, the energy efficiency is considered before making a decision. By choosing the 3x more efficient water maker offered by Elemental Water Makers, water savings of 55% are realised, equal to 112.000 $. Despite the 30% higher purchase price the payback is still less than 1 year, as energy generation on the island is expensive with 0.3 $/kWh.

The benefits: savings, stress-free operation & independence
The compact desalination solution allows the private island owner to enjoy high-quality water on-site, with stress-free operation & remote monitoring, whilst still saving 18 ton CO2 per year. This is a solution for future generations.

Assumptions: costs including installation and training | Yearly inflation of 2% | Reference RO energy consumption: 10 kWh/m³ | Water intake available | Financial lifetime 15 yrs | Technical lifetime >20 yrs | OpEx include consumables, spare parts and membrane replacement.
