Abstract
A process for removing soluble and insoluble inorganic, organic, and microbiological contaminants from a fluid stream employing a pretreatment module, a post-treatment module, a recharge stream module or any combination thereof, and an ion exchange module, is provided. The process provided reduces the problems associated with ion exchange material fouling and increases contaminant removal capacity.
Claims66
A process for treating a fluid stream containing soluble and insoluble inorganic and organic chemical contaminants, microbiological contaminants, or combinations thereof to reduce the concentration of these contaminants comprising:
- passing the fluid stream into contact with a high pressure side of a module to reduce both soluble and insoluble contaminants and to convert soluble contaminants into other forms present therein, and to recover from the low pressure side of the module a treated stream;
- and
- passing the fluid stream into contact with a high pressure side of an ion exchange module to remove additional insoluble and soluble chemical and microbiological contaminants present therein, and to recover from the low pressure side a treated ion exchange stream.
The process of claim 42, wherein the treatment module contains one or more of the individual components contained in bone charcoal.
