Oneka Iceberg-class

Oneka Technologies turns seawater into fresh water in an innovative and sustainable way by harnessing wave energy. The Iceberg-class unit was developed to deploy commercial-scale projects for coastal communities, industries and resorts. One unit can provide water for 100 to 1500 people per day depending on consumption. Oneka’s water quality is adjusted to meet the World Health Organization standards and/or local water standards. The production capacity is 30-50 m³ (8k-13k US gal)/day/unit (The production depends on wave height. The optimal quantity of buoys is calculated in order to meet water needs.) Dimensions: 5 m x 8 m (16 ft x 26 ft). Weight: 11,000 kg (23,000 lbs).
