Abstract
The present disclosure includes an embodiment to a method for treating water and/or a water handling system to decrease deposit formation and/or to remove a deposit. More particularly, to a method for treating water and/or a water handling system with one or more rare earths to decrease deposit formation and/or to remove a deposit. Struvite is an example of deposit material that can be removed and/or deposition inhibited by treating a water and/or water handling system with one or more earths.
Claims45
A process, comprising:
- contacting a rare earth-containing additive with a deposit material contained within a water handling system to one or both of remove the deposit material and inhibit deposition of the deposit material.
A process, comprising:
- contacting, within a water handling system, a rare earth-containing additive with a deposit material to form a deposit-laden rare composition and to one or both of remove the deposit from the water handling system and inhibit the formation of more deposit material within the water handling system.
A process, comprising:
- contacting a water handling system containing struvite with a rare earth-containing additive to form a rare earth composition comprising a component of the struvite and to one or both of remove the struvite from the water handling system and inhibit the formation of more struvite within the water handling system.
A system, comprising:
- a) a deposit-laden water handling system containing a deposit material adhered to a component of the water handling system;
- b) an input to receive a rare earth-containing additive, wherein the rare earth-containing additive is contacted with the deposit material to form a deposit-laden rare earth composition and to substantially remove the deposit material adhered to the component of the water handling system;
- and
- c) an output to output the deposit-laden rare earth composition and to form a deposit-free water handling system substantially lacking deposit material adhered to the water handling system.
