Blue lagoon technology brings the beach anywhere in the world

Blue lagoon technology brings the beach anywhere in the world

From coastal resorts to inner cities, these large-scale clear-water lagoons offer a slice of paradise.

By David Malone, Associate Editor | January 10, 2018

It used to be one had to fly to a remote island paradise if they wanted to enjoy the combination of white sand beaches and crystal clear blue waters. Thanks to patented technology, Crystal Lagoons is able to bring that experience anywhere in the world—from coastal resorts to inner cities to desert climates.

Founded in 2007 by Santiago, Chile-born biochemist and real estate developer Fernando Fischmann, Crystal Lagoons utilizes several proprietary technologies to reduce the cost and maintenance of—and thus greatly increase the applications for—large-scale lagoon installations. The lagoons can be built as big as a given space allows—the company’s largest installation to date, in Egypt, is nearly 31 acres—and can be maintained at relatively low costs while using minimal amounts of chemicals and energy.

Fischmann’s technology uses a pulse-based disinfection system that applies controlled pulses of small quantities of oxidants/micro-biocides to the lagoon water in relation to the growth cycles of algae and bacteria. The application of these additives is coordinated by injectors and sensors and managed remotely by the Crystal Lagoons team.



The system uses up to 100 times less chemicals than conventional swimming pool treatment technologies and consumes only 2% of the energy needed by conventional swimming pool filtration systems, according to the company.

The filtration system is also different, and more efficient, than conventional pools. Natural compounds and a variety of ultrasonic waves are applied to the water, which enables the contaminant particles to be agglomerated into larger particles that are later removed from the lagoon. This means only a small portion of the total water volume needs to be filtered.

Crystal Lagoons can use seawater, fresh water, or brackish water. They also capture rainwater to reduce the need for make-up water to compensate for evaporation.

The company recently developed a floating lagoon system, which uses decks and bridges paired with a proprietary floating structure to create a crystal-clear body of water without the use of land.

Crystal Lagoons has 15 projects in the works in the U.S., mainly in Arizona, California, Florida, Nevada, and Texas. Another 44 U.S. projects are in the feasibility/negotiation stage, worth some $53 billion.
