Due to an ongoing local drought, Reserva Conchal - a beach resort, golf course, and spa in Costa Rica - was facing water scarcity for several years, with more years of drought expected in the future.
This case study shows how Fluence introduced Costa Rica to containerized desalination, the best available option for Reserva Conchal in this extreme situation.
Next to the property a piece of land is set aside as a wildlife refuge, which is home to approximately 32 species of birds, 12 species of mammals, various reptiles and amphibians, as well as a wide range of local plant life. The reserve, which covers almost 100 acres, is extremely popular with Reserva Conchal guests and homeowners.
To secure a reliable source of drinking water and reduce reliance on stressed aquifers, in 2016, Reserva Conchal contacted Fluence to install a desalination plant.
Guanacaste's primary industry is tourism, and a lack of water could harm it. Nationally, the industry generated roughly $2.8 billion in revenue and employed 600,000 people both directly and indirectly in 2015, according to 体彩官网首页下载. That year, a record number of visitors from around the world -- 2.66 million -- visited the Central American country. According to Bank of Costa Rica data, tourism revenue is expected to reach $3.1 billion in 2017.
Coupled with increased demand from residents, water scarcity is a real problem, with potential repercussions throughout the economy.
Reserva Conchal needed a solution that would not affect the environment. Not only was a sustainable supply of high-quality, potable water needed, but the technology had to be housed in a way to prevent jarring noise from spoiling the natural setting. Above all, time was an urgent consideration.
Fluence's Nirobox provided Reserva Conchal with an attractive option. The containerized system could provide all the benefits of desalination without requiring a huge footprint or extensive infrastructure investment. It could easily blend in with the surroundings without damaging the landscape. And its plug-and-play design meant it could be up and running in very little time.
The client needed a solution with a high recovery rate that featured low energy consumption and required minimal use of chemicals. The system had to be quiet, have a small physical footprint, and a low ecological impact. A "smart" intake and discharge capability was needed to minimize impacts associated with intake suction and to diffuse the brine as much as possible.
The process flow treats a 35,000ppm TDS seawater feed with:
- Disc filtration
- Reverse osmosis
- Remineralization to drinking water quality
The installation of three Nirobox units was designed to have a total capacity of approximately 1,500 m3/d of drinking water. The system was started up only eight months after it was ordered, with a plan to gradually increase reliance on the system with the approach of tourist season.
Fluence was able to help Reserva Conchal quickly secure a reliable, cost-effective, and energy-efficient source of water without disturbing the local environment.
