Summary:

Traditional oil, gas, and mining industries rely heavily on the use of water as a means to aid in the recovery of natural resources. Often times these activities, either through mechanical shear or chemical additives, enhance the colloidal suspension of well dispersed, fine materials such as clay, ore, fine sand, and silt. Re-use of the resulting produced water can be difficult unless the suspended solid material is quickly and efficiently removed. A new water treatment technology, ATATM, has been developed that is capable of rapidly separating clays and other fine particulates from waste streams. The process immediately liberates clear water for reuse and aggregates the suspended solids making them well suited for dewatering and disposal. Applications in traditional oil and gas as well as mining markets offer benefits including efficient use of water resources and rapid reclamation of disturbed land.
