Processing of the liquid fraction

Adsorption / Ionic exchange

Adsorption / Ionic exchange

Objective

Capturing waste water nutrients by adhesion to a surface

Inlets

Wastewater and other liquid streams rich in phosphate and/or ammonium. In ion exchange, phosphates can be adsorbed on a medium that favors the exchange with other ions such as Cl-.

Efficiency

Not available

Weaknesses

It is necessary to use chemical reagents (NaOH or brine) to regenerate the adsorbent agent;
During regeneration, it is not possible to desorb 100% of retained nutrients;
Susceptible to biofouling;
It requires a low concentration of suspended solids in the influent water to avoid clogging;

Products
