Solution: Efficient Watermaker 2018-04-09T11:31:13+00:00

Using your energy.
Energy available? Get our efficient water maker.

We understand that water and energy are not always considered at the same time. If you already enjoy renewable energy or currently have an affordable energy solution in place, we can hook you up with an energy efficient desalination solution that’s easy to operate and maintain.

Especially for small-scale solutions, energy efficiency is often lacking. To avoid high electricity bills, our efficient reverse osmosis units operate around 2.2 kWh/m³ or 8.3 kWh/1,000 gallons energy consumption for seawater. Industry standard solutions can consume over 3x more energy.

The compact & user-friendly units are designed for corrosive environments and the energy recovery device is maintenance free. GSM monitoring is available for remote control and an automated fresh flush system is included.

Sizes start small and go up to large capacities. The units are available in different voltages, phases and frequencies to meet the local power supply.

”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.

Reverse osmosis with low energy consumption, even at small-scale. 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.

Example case: efficient desalination.
A private island enjoying guilt-free water.

The problem
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 purchase price.

The solution
Luckily, 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
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.
