  • Processing cooling tower blowdown to produce fertilizer
    Patent number: 11897791
    Abstract: A blowdown water stream from a cooling tower is contacted with an ion exchange resin packing, such that at least a portion of the phosphorus from the blowdown water stream adsorbs to the ion exchange resin packing to produce a water stream that has a phosphorus content that is less than a phosphorus content of the blowdown water stream. A regenerant stream is contacted with the ion exchange resin packing, such that at least a portion of the phosphorus that has adsorbed to the ion exchange resin packing, desorbs from the ion exchange resin packing to produce a spent regenerant stream. The spent regenerant stream, a first reactant stream including magnesium ions, and a second reactant stream including ammonium ions are flowed to a reaction vessel. The spent regenerant stream, the first reactant stream, and the second reactant stream are mixed to produce a product that includes struvite.
