“…Another way to chemically remove phosphorus from wastewater is to filter it through an active filter bed [11,12], which, using sorption [13] and ion exchange processes, retains phosphorus primarily in the form of phosphates. This method of phosphorus removal is used in wastewater treatment plants at the end of the process line when the wastewater is already free of organic pollutants.…”

“…In the literature, one can find publications in which various minerals and reactive materials were studied [14][15][16][17][18][19][20][21][22]. Among them, carbonatesilica rock (ophiolite) has also been mentioned as a sorbent with a high capacity to absorb phosphorus [12,18,[23][24][25].…”

“…It is produced by decarbonizing (high-temperature firing) the opoka, thereby making it a much more reactive material toward phosphorus than natural opoka [32]. Laboratory studies indicate that, with this material and a sufficiently long contact time, it is possible to remove more than 90% of the total phosphorus from wastewater [12]. In contrast, preliminary studies conducted on a full technical scale have shown a phosphorus removal efficiency of about 40% [18].…”

Chemical phosphorus removal in wastewater treatment plants can be carried out by precipitation with iron or aluminum salts or by filtering wastewater through a bed of active sorptive material. This work aimed to investigate whether using a meander flow filter filled with the sorption material Rockfos® would improve phosphorus removal efficiency in a selected wastewater treatment plant. Tests were performed under laboratory conditions using a model of a meander flow filter and a similar filter under field conditions at full technical scale. This filter was the final element of a hybrid constructed wetland located in the village of Białka in the municipality of Dębowa Kłoda in southeastern Poland. A laboratory model of a phosphorus removal filter with vertical incomplete baffles forcing a meandering water flow was constructed to determine the hydraulic conditions of the flow. After one year of operation, the filter with horizontal wastewater flow operating at its full technical scale (without meanders) was modified by inserting appropriate baffles that were analogous to those in the laboratory model. The analysis of the hydraulic conditions in the laboratory model showed that, under the assumed conditions, wastewater flows through the filter layer in a laminar motion, so such filters can be modeled using the Kozeny–Carman formula. It was shown that, after approximately a year of operation in a filter operating at full technical scale, before modification, dead spaces formed, thus causing the channel and primarily surface flow of wastewater. The phosphorus removal efficiency during this test period averaged 9.4%. After introducing baffles and forcing meander flow in the filter chamber, the efficiency increased to 40.6%. The results indicate that meander flow filters can improve phosphorus removal efficiency in small wastewater treatment plants.

“…Municipal and industrial wastewater is a carrier of many dangerous organisms and substances, which include parasites and pathogenic organisms [ 1 , 2 , 3 ], toxic substances and compounds disturbing the natural biological balance in treated sewage receivers by increasing the saprobicity and eutrophication of these waters [ 4 , 5 , 6 ]. Such wastewater can be neutralized by mechanical–biological or mechanical–biological–chemical methods of treatment with the use of activated sludge.…”

COD is an arbitrary indicator of the content of organic and inorganic compounds in wastewater. The aim of this research was to determine the effect of COD of industrial wastewater on the nitrification process. This research covered wastewater from acrylonitrile and styrene–butadiene rubbers, emulsifiers, polyvinyl acetate, styrene, solvents (butyl acetate, ethyl acetate) and owipian® (self-extinguishing polystyrene intended for expansion) production. The volume of the analyzed wastewater reflected the active sludge load in the real biological treatment system. This research was carried out by the method of short-term tests. The nitrification process was inhibited to the greatest extent by wastewater from the production of acrylonitrile (approx. 51%) and styrene–butadiene (approx. 60%) rubbers. In these wastewaters, nitrification inhibition occurred due to the high COD load and the presence of inhibitors. Four-fold dilution of the samples resulted in a two-fold reduction in the inhibition of nitrification. On the other hand, in the wastewater from the production of emulsifiers and polyvinyl acetate, a two-fold reduction in COD (to the values of 226.4 mgO2·dm−3 and 329.8 mgO2·dm−3, respectively) resulted in a significant decrease in nitrification inhibition. Wastewater from the production of styrene, solvents (butyl acetate, ethyl acetate) and owipian® inhibited nitrification under the influence of strong inhibitors. Lowering the COD value of these wastewaters did not significantly reduce the inhibition of nitrification.

La utilización de la microalga Chlorella vulgaris son una opción ecoamigable y rentable principalmente si se integra en la depuración del agua residual empleando la materia orgánica y nutriente presente del agua como medio de cultivo. Es así, que el objetivo en este estudio fue evaluar la eficiencia de remoción de materia orgánica mediante el uso de la microalga C. vulgaris en las aguas residuales municipales del distrito de Monzón (Huánuco). Para determinar la capacidad de remoción se empleó un sistema de crecimiento de cultivo llamado “Biorreactor” por un periodo de 17 días donde el análisis físico-químico de las muestras a tratar fueron antes y después del experimento, asimismo se monitoreó diariamente el crecimiento de la microalga a través de la cuantificación de peso seco, velocidad especifica de crecimiento, productividad, temperatura, pH y las lecturas de absorbancia. El experimento contó con tres unidades experimentales sin el agua residual y tres unidades con el agua residual a una concentración de 21%. Los valores de porcentaje de remoción para el DQO, DBO, fosfato y nitrato fueron -293.0%, 41.9%, 69.13% y -107 592%, respectivamente. Donde el valor negativo del DQO se relacionó con la descomposición de las microalgas viejas a través de las bacterias y la liberación de la materia orgánica (sustancias poliméricas extracelulares ) luego que las microalgas fijaran el CO2, y para el valor negativo de nitrato se relacionó con la presencia de bacterias nitrificantes (BN). Por otra parte, los metales pesados como Ni, Cr, Pb y Cd fueron ligeramente superiores al Límite Máximo-Permisible (LMP).En conclusión, se ha demostrado que, si es posible la biorremediación de aguas residuales municipales a partir del cultivo de C. vulgaris.
