Abstract
This disclosure relates to systems and methods for purifying water, such as produced water used in fracking operations, by using an aqueous brine composition with a flocculant to separate and remove solids from the water. The aqueous brine composition can include a flocculant polymer that is partially hydrated in and suspended or dispersed in the aqueous brine composition. The aqueous brine composition can be added directed to the water without prior dilution, or with only minimal dilution.
Claims21
A method of purifying water, the method comprising:
- providing an aqueous brine composition that includes a flocculant polymer;
- adding the aqueous brine composition to a water stream that includes suspended solids;
- treating the water stream by causing the suspended solids to aggregate with the flocculant polymer;
- and
- separating the aggregated solids from the water stream to provide a purified water stream.
2 more elements
A system for purifying water that comprises:
- a water stream that includes suspended solids;
- a polymer injection system that includes:
- (i) a container with an aqueous brine composition that includes a flocculant polymer;
- and
- (ii) a dosing pump that is configured to receive the aqueous brine composition from the container and pump the aqueous brine composition through an injection port to add the aqueous brine composition to the water stream;
- and
- a separation unit that is configured to receive the water stream that includes the aqueous brine composition, cause the suspended solids in the water to aggregate with the flocculant polymer, and separate the aggregated solids from the water stream to provide a purified water stream.
