Post-Removal of Phosphorus from Biologically Treated Wastewater and Recovering It as Fertilizer. A Pilot-Scale Attempt—The Project PhoReSe

Published: April 30, 2024

The major issue of raw materials depletion and more specifically phosphorous (an important fertilizer) has currently become an emergent aspect, due to expected problems, needing immediate handling. This was the reason for implementation PhoReSe project that aimed remove recover phosphorus from secondary (biologically treated) effluent a municipal wastewater treatment plant (WWTP “AINEIA”, located near Thessaloniki, N. Greece), treating wastewaters nearby touristic area. Regarding supplementary removal recovery options, two methods mainly examined, initially in laboratory scale (batch experiments), i.e. (1) adsorption phosphorous, (2) chemical precipitation phosphorus. Both further applied pilot-scale, by performing onto AquAsZero commercial sorbent, which is mixed manganese iron oxy-hydroxide, followed implemented after de-sorption process previously saturated adsorbent. final precipitate this procedure examined as alternative/supplementary fertilizer, returning with way into natural cycle. These experiments, successfully set basis larger-scale relevant application similar WWTP facilities.

The use of Chlorella vulgaris in reducing the organic load of poultry slaughterhouse wastewater: Modeling and optimization of influential factors in the process

Environmental Health Engineering and Management, Journal Year: 2024, Volume and Issue: 11(2), P. 147 - 159

Published: June 4, 2024

Background: Wastewater from poultry slaughterhouses is a serious environmental threat if they are incompletely treated. Recently, the utilization of microalgal species has gained significant attention for treating such wastewater. Chlorella vulgaris one most efficient microalgae slaughterhouse wastewater due to its exceptional capacity N, P, and chemical oxygen demand (COD) removal. This study aimed investigate impact initial total nitrogen concentration, phosphorus, photoperiod, cultivation time on reducing organic load enhancing production biomass in Methods: Samples were collected effluent underwent qualitative analysis. C. was cultivated BBM culture medium. Experiments designed using response surface method. The experiments then carried out obtained data subjected analysis variance (ANOVA), resulting fitted models removal production. Numerical optimization performed optimize COD increase algal biomass. Finally, validated. Results: results demonstrated that quadratic model good fit data. In optimal conditions, including TN=600 mg/L, TP=34 duration=15 d, photoperiod=12.6 hr, efficiency 93.88% 92.37%, respectively. Conclusion: exhibits potential effluent. Also, substantial generated, which can be used various areas as livestock feed sanitary uses.
