Desalination Plants

DESALINATION PLANTS

Reverse Osmosis
The current global problem of equitable access to safe and affordable drinking water is being efficiently addressed through the use of purification techniques, seawater desalination or wastewater recovery.
Through commercial alliances built with the best manufacturers of desalination systems around the world, we have specialized in the supply and installation of reverse osmosis desalination plants. We take care of your previous water analysis, civil engineering, procurement, construction commissioning, training and maintenance of the desalination plants installed by us.
The process of reverse osmosis consists of the demineralization of sea water in three fundamental stages:

Pretreatment:
Pretreatment is required to increase the efficiency and life expectancy of the membrane elements by minimizing fouling, scaling and degradation of the membrane, and it consists in the elimination of: sodium, calcium, boron, sulfates, nitrates, bicarbonates, heavy metals like iron, magnesium and mercury, as well as viruses and bacteria.
Reverse osmosis consists in applying a pressure, thanks to a gas system, superior to osmotic pressure. When this pressure is applied, the flux reverses. Because the membrane is semi permeable, salt, impurities, virus, bacteria, can’t pass through the membrane, and we obtain drinking freshwater. This technique eliminates all molecules largest than one micrometer. This process requires water pre-treatment to eliminate largest impurities that could fill the membrane holes and a mineralization too.
In addition, our plants have energy recovery systems to save 45% of energy used and are equipped with the most advanced technology and wireless controlling system.
The brine disposal is done in a safe manner and complying with environmental parameters.

Post-treatment:
Post-treatment processes include disinfection using suitable biocides, pH adjustment, and possibly the addition of suitable corrosion inhibitors.
Water treated by reverse osmosis does not have the quantity of salts and the right Ph to make it suitable for human consumption so it must be subjected to a remineralization processes with calcium and magnesium; While for the removal of chlorine and boron, a solutions of NaOH / HLC and caustic soda are injected into the water flow. Once all these steps have been performed, the water treated by reverse osmosis is suitable for human consumption.
We have Containerized and modular plants of different capacities ranging from 5 GPD up to 1,500,000 GPD.
Our staff is capable of offering various solutions for the location of equipment, water quality, brine disposal, handling of possible environmental impacts, storage and distribution of the product.
All our equipment is manufactured to the strictest standards and they are backed by the most renowned brands in the market, which guarantees the optimum and continuous operation of the plants.
