Textile is an industry in which dyeing, bleaching, printing and finishing grey fabrics uses large amounts of water. Treatment of this textile wastewater is difficult due to the variety of materials and processes used. Membrane distillation allows to significantly reduce water consumption in textile factories, moving towards zero liquid discharge.
The global production of produced water by the oil & gas industry is estimated at 250 million barrels per day. This produced water contains several organic and inorganic components, which creates the need of a complex design of cost-effective, flexible and low-footprint treatment plants to separate the oil and to obtain a water effluent with sufficient quality for further treatment, discharge or reuse.
In many off-grid locations generator sets are used to provide electricity. In these applications there is also a need for fresh water. Generator sets produce exergy waste heat. Membrane distillation can consume this waste heat as input thermal energy for the process. Providing both a cooling source for the generator sets and clean water.
Sources of clean water in small rural communities in remote sunny locations, not connected to the water and/or electricity grid, are becoming an increasing scarcity. These communities are in dire need of potable water. Combining the thermal power of the sun with membrane technology Aquastill provides clean water for these locations.
