The occurrence and fate of five acidic drugs (Mefenamic acid, Ibuprofen, Ketoprofen, Diclofenac and Clofibric acid) were analysed in three sewage treatment plants (STP) over 4-7 consecutive days. The results point out that the five substances were persistent in wastewater effluents after municipal wastewater treatment. At the most, half of Mefenamic acid was eliminated. Ibuprofen was well remov...
Effect of Municipal Wastewater on the Accumulation of Heavy Metals Cadmium and Lead in Soil and Corn
Background and Objective: Using wastewater as a renewable water source to irrigate plants is a safe and effective solution. In contrast, the accumulation of heavy elements in soil and plants is one of the concerns of the use of wastewater in agriculture. This study was conducted to investigate the effects of urban wastewater use on the most important physiological parameters related to the grow...
The current paper assesses the reliability coefficients of fifty six low-cost, full-scale wastewater treatment plants, including nine different treatment technologies for wastewater reuse in aquaculture and agriculture in northeast Brazil. This was carried out with the aim to evaluate alternatives for sustainable wastewater reuse in communities experiencing water scarcity. The technologies eval...
introduction in the wastewater treatment industry, the general attentionis mostly paidto the effluent quality standards. regardless of energy consumption, the treatment plants have been designed based on experience rather than the latest scientific findings.the treatment plants are considered as a part of energy equipment which largely consumed electrical energy.thus, electricity is the great p...
Wastewater generated by domestic, municipal, and industrial sectors has been increasingly used, particularly in dry areas, to provide water and nutrients to agriculture, aquaculture, and agroforestry systems. While such use helps in income generation and livelihood resilience amid water scarcity, use of wastewater in untreated or inadequately treated forms may result in negative impacts on huma...
The increasing importance of environmental problems in the last decades, and the consequently stricter regulations adopted, require a holistic approach in control and operation of wastewater process, whose primary objective is to maintain a good state of the receiving waters. This paper reports the study focused on building a Fuzzy Logic Control for integrated wastewater systems. The control in...
Wastewater treatment plants affect the environment in many different ways. It can be assumed that the intensity and range of microbiological emission is the crucial factor in determining the range of restrictedusage zone. This paper presents emission levels of microbiological pollutants from the wastewater treatment plant in Bartoszyce, Poland. It is a new plant with multifunctional activated-s...
Decentralized water reclamation is emerging as a new paradigm that pairs local wastewater resources with local users; however, one of the challenges that must be addressed to advance its implementation is the low energy efficiency associated with small treatment plants and the lack of available small-scale energy recovery technologies. Gasification is a technology that could be used to convert ...
This study investigates the level of wastewater pollution by analyzing its chemical characteristics at five wastewater collectors. Samples are collected before they discharge into the Danube during a monitoring campaign of two weeks. Organic and inorganic compounds, heavy metals, and biogenic compounds have been analyzed using potentiometric and spectrophotometric methods. Experimental results ...
