Containerized Seawater Desalination in Cape Verde
Cape Verde, an island nation off the coast of West Africa, faces seasonal freshwater scarcity due to limited natural water resources and increasing residential demand. A local utility company partnered with us to deploy a containerized seawater reverse osmosis (SWRO) system to provide reliable potable water for domestic use.
The objective was to design a system that is modular, easy to transport, quick to install, and capable of operating efficiently in coastal environments with high salinity and variable power conditions.
Our Solution: Containerized SWRO System
We supplied a fully integrated, containerized seawater desalination unit, built and tested at our facility before shipment. Key features of the system include:
- ISO 40-foot container, corrosion-resistant stainless steel frame, insulated and climate-adapted for marine use
- Production Capacity: 10 m³/h (10,000 liters/hour) of potable water
- Seawater RO Membranes: High-rejection membranes designed for >35,000 ppm TDS
- Pre-treatment System: Includes media filter (sand or MMF), cartridge filter, and antiscalant dosing
- Automation: PLC control with HMI panel, optional remote monitoring
- Power Supply: Configurable for 380V/50Hz or other regional standards

Our 500 LPH Reverse Osmosis (RO) System is engineered to provide high-quality purified water for commercial applications. Designed with advanced RO technology, durable components, and a user-friendly interface, this system ensures consistent performance, low maintenance, and long-term reliability.
With its compact design and robust skid-mounted frame, it’s an excellent choice for businesses that demand efficiency and quality in water purification.
UV Water Sterilizer Systems are advanced water purification devices that utilize ultraviolet (UV) light to eliminate harmful microorganisms such as bacteria, viruses, and protozoa from water. These systems are highly effective, environmentally friendly, and do not require the use of chemicals, making them a popular choice for both residential and commercial applications. UV sterilizers are often used in conjunction with other filtration methods, such as reverse osmosis or carbon filters, to ensure comprehensive water treatment. They are easy to install, require minimal maintenance, and provide a reliable method for ensuring safe and clean drinking water.
A water softener is a specialized filtration system designed to remove hardness-causing minerals, primarily calcium and magnesium, from water. Hard water can lead to scale buildup in pipes, appliances, and fixtures, reducing their efficiency and lifespan. By using an ion exchange process, water softeners replace these hardness minerals with sodium or potassium ions, effectively softening the water.
Water softeners are widely used in residential, commercial, and industrial applications to improve water quality, enhance appliance performance, and prevent plumbing issues. Softened water also provides benefits such as better lathering of soaps and detergents, reduced soap scum, and improved efficiency of water heaters and other appliances. With their ability to extend the life of plumbing systems and reduce maintenance costs, water softeners are an essential solution for managing hard water problems effectively.
A Water Deionizer is a specialized water purification system designed to remove dissolved ions, minerals, and contaminants from water through an ion exchange process. It effectively eliminates both cations (such as calcium, magnesium, sodium, and iron) and anions (such as chloride, sulfate, nitrate, and bicarbonate), resulting in high-purity deionized (DI) water.
Our Two Bed Deionized System is a reliable and cost-effective water treatment solution designed to produce high purity demineralized water. Using separate cation exchange resin and anion exchange resin columns, the system effectively removes dissolved salts, minerals, and impurities from raw water.
