US 8,147,697 B2 · Apparatus and process for desalination of brackish water

Abstract

Water from underground and other sources of water are brackish and not suitable for human consumption. Naturally present dissolved chemicals in water make it brackish. The precipitants and dissolved chemicals need to be separated from water to make it consumable. A combination of aeration systems, filtration systems, crystallizers and hydrophobic membrane carrying filter are used to desalinate the brackish water. Solar energy and ceramic filters are used as add on to existing technology. Various heat exchange apparatus are used for energy conservation and efficient processing of water in a feasible way. The disclosure enables to purify water and provide a useful technology to eradicate water scarcity.

Dependent claims

An apparatus, comprising:

an aeration system having a conical vessel, a smooth inner surface and a scrubber to separate a precipitating particle from a brackish water;
a filtration unit to remove a suspended particle in the brackish water and sending a filtered water for further processing;
a distillation system to process brackish water, wherein the distillation system is at least one of a vacuum membrane distillation system, a membrane distillation system, a direct contact membrane distillation and a membrane distillation bioreactor;
and
a crystallized unit connected to at least one of a membrane filtration system and a heat exchanger to collect at least one of the suspended particle and a concentrated particle for making an adsorbent.
