A successful air stripping as pretreatment step was performed by Zhang et al. to increase the methane yield from AD of piggery wastewater. The ammonia stripping pre-treatment showed that the removal of ammonia seemed to be dependent on pH and aeration rate, and particularly, it could be an option at alkaline pH levels to prevent digester failure during anaerobic treatment of raw piggery wastewater.

VaSA for, Ammonia, Recovery from, Wastewater., Vacuum Stripping and Absorption (VaSA) couples vacuum thermal stripping and, acid absorption, to pull, ammonia, out of ammonia-rich wastewater (e.g., anaerobic digestate, landfill leachate, and source-separated urine) to form, ammonium, sulfate granules, a sellable nitrogen fertilizer and reagent-grade chemical.

Recently, a process of vacuum thermal stripping coupled with acid absorption was invented to recover ammonia from digestate and ammonia-rich wastewater (Ukwuani & Tao 2016). It appears to be the most efficient ammonia recovery process, stripping ≥93% of ammonia out of dairy manure digestate and swine manure in 1–3 h ( Ukwuani & Tao 2016 ; Zhang et al. 2017 ).
