Pharmaceutical wastewater

Ebook "Green technologies for wastewater treatment: Energy recovery and emerging compounds removal" evaluates water management together with energy use. The strong effects that the release of emerging pollutants such as endocrine disruptors (EDCs), pharmaceuticals and personal care products (PPCPs) have in wastewater reuse applications are examined, as well as the need to optimize the energy consumption in wastewater treatment.

In this study, a simple, selective, and accurate analysis method was developed for the simultaneous determination of anti-inflammatory drugs (paracetamol and diclofenac) existing inlet and outlet of the wastewater treatment system. This method used solid-phase extraction (SPE) and reversed-phase high-performance liquid chromatography with a photodiode array detector (HPLC-PDA).

Water treatment has been an essential issue with the increasing population over 40 years. Researchers center on the major organic pollutants, such as dyes, pesticides, and pharmaceutical products. Photocatalytic degradation is one of the promising methods for aquatic organic pollutant treatment. Over the years, scientists have been working on developments for photocatalysts to enhance their pollutant degradation performances.

Many pharmacologically active compounds are chiral species, and their therapeutic or toxicological effects might differ between isomers. Herein, we develop a fast and sensitive chiral analysis methodology for the determination of eight pharmaceuticals, considered as emerging environmental pollutants and belonging to two different chemical classes, in wastewater and sludge samples.

In this work, we review various PhCs detected in water treatment plants. We propose that fungi, particularly white-rot fungi (WRF), can be used for their bioremediation and describe the main mechanisms used for degrading this type of emerging pollutants; however, we also highlight the need to prospect for new fungal models.

The bioaugmentation for removing the pharmaceuticals in municipal wastewater by Trametes versicolor and Aspergillus luchuensis using fluidized bed pelleted bioreactor was studied. To find the optimal performance of bioaugmentation by both fungi periodical biomass volume, 10 and 50 g per 1.25 L bioreactor, were tested.

In this study, natural clinoptilolite was modified by saponin and Brij 35 surfactants to remove diethylstilbestrol (DES) from wastewater in batch and continuous systems. The optimum pH, amount of adsorbent, contact time, and temperature were 11, 10 g/L, 12 h, and 35°C, respectively, for the process. The equilibrium data agreed well with the Langmuir isotherm for natural clinoptilolite (NC), natural clinoptilolite modified by Brij 35 (NC-Brij), and natural clinoptilolite modified by saponin surfactants (NC-saponin) compared to other isotherms.

Spirulina is noticed for great applications on food supplements, animal feeds, pharmaceutical, cosmetics, biofuel, fertilizer, etc. Spirulina cultures in wastewaters could enhance the feasibility of commodities due to its ability to reduce the cost of biomass production and remove pollutants in wastewaters. This study investigates the effects of wastewater pretreatment using various aeration periods (i.e. from 3 to 7 days), the supplement of bicarbonate and N:P ratios on the growth of Spirulina sp. to produce protein-rich biomass. The work showed that Spirulina sp.

Nowadays, synthetic dyes are widely used in textile, leather, cosmetics, paper, food and pharmaceutical industries instead of natural dyes due to its availability, stability, low cost and color intensity which emerges a new problem of residual color in the discharged effluent. Improper discharge of dye effluent in aqueous ecosystems is aesthetically unpleasant and impedes photosynthetic activity reducing sunlight penetration, dissolved oxygen concentration and water quality in total.

Wastewater of Sao Thai Duong Pharmaceuticals & Cosmetics Factory contains high concentration (more than 1000 mg/l) COD and BOD. Besides, some persistent substances are also found such as surfactants, emulsion oil and ammonium. Especially, the quite low BOD/COD ratio of 0.3 makes the treatment process of organic matters more complicated. Furthermore, the troublesome settlement of oil emulsions inhibits the wastewater biological treatment process which results in difficulties for selection of a stable and sustainable technology.

Distillery is one of the most highly polluting and growth oriented industries in India with reference to the extent of water pollution and the quantity of wastewater generated. Apart from distilleries, fermentation industries, sugar mills, pharmaceutical companies and other molasses based industries are also responsible for contamination and generation of waste water. The distillery waste water contains dark brown colored recalcitrant compounds collectively termed as melanoidin polymers. These polymers cause oxygen depletion and increase BOD.
