“…In general, the design and size of a test station used in a technological investigation depends on the purpose and object of a study, including the characteristics of the investigated processes, systems or equipment [1][2][3][4][5][6][7][8][9][10][11][12].…”

The purpose of pre-design technological investigations is to define the water treatment technology for a new or existing water treatment plant. The investigation is performed on model-scale equipment, making sure that the results can be extrapolated to the technological scale. The investigation should allow for the determination of unit process parameters and ensure the desired outcome i.e. treated water meeting the applicable quality standards. Indirectly, the investigation results can also be used as a basis for defining the estimated scope of the investment, the costs of its execution and the future equipment operating costs. Technological investigations are carried out on the grounds of existing or future treatment plants in order to take into account the variable composition and quality indicators of the raw water to be treated. The pilot station, being the main element of the technological investigation, should be designed, built and operated with a view to the possibility of formulating further design guidelines after the study is completed. In this article, the authors share their experience related to the configuration of a pilot station used in an investigation of a groundwater treatment technology.

“…However, these aforementioned methods are expensive. They could result in metabolites that can potentially be more harmful than the parent organic chemicals [1] [30] [31]. Additionally, the chemical contaminants in the wastewater have been shown to enter surface water through combined sewer overflow during wet weather conditions.…”

Pharmaceuticals have been detected nationwide in different environmental matrices including wastewater effluents and surface water. In recent studies, pharmaceuticals have also been found in aquatic plants, fish tissues and plasma of shark bulls. Pharmaceuticals that were detected as indicated in published literature, included steroids, prescription drugs such as antibiotics, anti-depressants, anti-inflammatory drugs, hormones and over the counter (OTC) drugs. We conducted a monitoring study to detect the presence of pharmaceuticals in East fork of the Stones River located in Rutherford County in Middle Tennessee. East Fork Stones River is a six (6) order river that drains a large portion of Rutherford County including Murfreesboro, Tennessee. Grab water samples were collected from Stones River for three seasons: (summer and fall of 2014 and 2015 and winter of 2015 and 2016) each year. Water quality parameters were also determined in situ using Eureka Water Probes TM multi-parameter sondes. Water samples were analyzed for the presence of pharmaceutical compounds using GC-MS. Chemical Abstract Service Registry Numbers (CASRN or CAS) for detected pharmaceuticals were identified. Pharmaceuticals detected included those used for treatment of chronic alcoholism (Disulfiram: CAS # 97-77-8), a compound (Thiazolidine: CAS # 504-78-9) in the drug Thiazolidinedione which is used for the treatment of type II diabetes, a compound associated with the prevention of anti-inflammatory conditions (Methyl palmitate: CAS # 112-39-0), and emollient in skincare (Undecane: CAS # 1120-21-4). While the quantitative concentrations of these drugs were not determined in this study, their qualitative presence in surface water is noteworthy.

“…Based on advanced oxidation processes (AOPs), quantities of processing technics have been studies to degrade ATZ, such as ozonation, photocatalysis, activation of hydrogen peroxide, persulfate (PS) and peroxymonosulfate (PMS) [6][7][8][9][10][11]. Among these treatment processes, activations of PS and PMS are more excellent than others.…”

In this work, molybdenite was used as a catalyst to activate peroxymonosulfate (PMS) for atrazine (ATZ) degradation. First, the effects of molybdenite dosage (0.05-0.30 g/L), PMS dosage (0.02-0.15 mM) and the initial pH (3.0-11.0) in the aqueous solution on the ATZ degradation were investigated in the molybdenite/PMS system. The maximum degradation efficiency of ATZ (95.0%) after 10 min treatment was obtained at the molybdenite dosage of 0.2 g/L, PMS dosage of 0.08 mM and initial pH of 6.4. The control experiments suggested that molybdenite, which activate PMS had better performance than commercial molybdenum disulfide. It was found that the degradation efficiency of ATZ under the optimal parameters was only 41.2% in the commercial molybdenum disulfide/PMS system. The free radicals in the molybdenite/PMS system were studied by quenching experiment. The results showed that both SO4• and HO• were existed in the molybdenite/PMS system. In general, this study provided a natural catalyst for PMS activation and would urge us re-evaluate the capacity of natural materials as catalysts.
