Augmented growth of haematococcus pluvialis using nutrients from post hydrothermal liquefaction wastewater (PHWW)
… recycled nutrients from the post HTL wastewater (PHWW) or other wastewater sources for growing algae can reduce costs and synthetic nutrient inputs, which improves the sustainability of algae cultivation operations. In the first part of this work, we determined an appropriate dilution of PHWW to …

Treatment of post hydrothermal liquefaction wastewater and suitability for hydroponic lettuce production
… post-hydrothermal liquefaction wastewater (PHWW), has the potential to be used as a means of providing nutrients and water to crop production systems. In order to effectively used in food production, PHWW as a crop fertilizer has to be established as being productive and safe. The literature …

Improving integrated systems for algal biofuels and wastewater treatment
… of municipal wastewater and post-HTL wastewater (PHWW), which is an important step in the E2-Energy system. During 800 days of operation covering a range of operating conditions (15-20 day SRT, 1% to 4% PHWW loading rate, with and without GAC), the PBR supported stable and efficient removal of …

Improving algal biofuel production through nutrient recycling and characterization of photosynthetic anomalies in mutant algae species
… for biofuel production. The post-HTL wastewater (PHWW) accumulates most of the nutrients from the incoming biomass and this can subsequently be fed back to the algae culturing system to recycle nutrients for multiple cycles of algae growth. A series of algae cultivation and hydrothermal conversion …

Adsorbent-based algal cultivation system to facilitate integration of algal biofuel production with wastewater treatment
… continuous recycling of HTL aqueous product (PHWW). The system without adsorbents had a significant reduction of biomass productivity when the PHWW concentration in the influent was above 1.5%. In contrast, the system with adsorbents had increased biomass productivity when PHWW added. The …

Hydrothermal processes to recover energy and nutrients from liquid portion of swine manure
… oil production, but the post HTL wastewater (PHWW) was still high in organics, thus a secondary process of catalytic hydrothermal liquefaction (CHG) was used to mitigate the high COD level, and recovery the energy from the organics in forms of biogas. Another approach was to directly treat the …

The co-cultivation of rice and algae to improve process economics for algal biofuel production
… rice yield. LSD analysis showed that the Swine/PHWW Plus Plastic treatment was statistically different compared to the baseline treatment of Water Plus No Plastic while HSD analysis determined it was not statistically different. Overall, it was determined that yields were at worst the same while …
