Abstract:

Water treatment plant (WTP) residual discharge is considered a pollutant and requires treatment to prevent negative impacts when released to the environment. As regulatory requirement becomes increasingly strict, WTPs are required to find suitable methods for the treatment of sludge residuals. Wastewater treatment plants(WWTP) provide existing treatment methods to remove contaminants from WTP residuals. A case study on the Carbondale Water Treatment Plant (CWTP) and receiving Carbondale Southeast Waste Water Treatment Plant (SEWWTP) provided an opportunity to quantify potential negative imp

Abstract:

As estações de tratamento de água de abastecimento (ETAs) têm a finalidade de fornecer água potável. Neste processo de tratamento de água são gerados resíduos, os quais historicamente têm sido lançados em cursos de água, aumentando o nível de degradação destes. O presente trabalho teve por objetivo avaliar o impacto do lançamento desses resíduos numa estação de tratamento de esgoto (ETE) com reator anaeróbio de fluxo ascendente e manto de lodo (UASB), buscando estudar uma alternativa para a disposição adequada desses resíduos.

Abstract:

Pharmaceutical residues are passing our wastewater treatment plants and flowing out in to the nature. The medical substances are built to affect different processes in our bodies, but also affect other species and increase the risk of developing multi resistant bacterial strains, not curable with antibiotics. This has made wastewater treatment plants (WWTPs) interested in investing in pharmaceutical removal. This study describes what criteria that are important to consider when choosing technology for pharmaceutical removal, and presents a model for the WWTPs to use when choosing pharmaceutica

Abstract:

The provision of clean drinking water typically involves treatment processes to remove contaminants. The conventional process involves coagulation with hydrolysing metal salts, typically of aluminium (‘alum’) or trivalent iron (‘ferric’). Along with the product water this also produces a waste by-product, or sludge. The fact of increasing sludge production — due to higher levels of treatment and greater volume of water supply — conflicts with modern demands for environmental best practice, leading to higher financial costs. A further issue is the significant quantity of water that is held

Emerging organic contaminants (EOCs) have been the focus of global environmental research for over three decades. EOCs have caused widespread concern due to their extensive use.

However, there is limited knowledge about their unintended effects in the environment. To address the occurrence, distribution and fate of EOCs in the environment, efficient and reliable analytical methods are needed. The relatively low concentration,

Abstract:

The David L. Tippin Water Treatment Facility (DLTWTF) serving the city of Tampa, Florida is an advanced drinking water treatment facility consisting of coagulation/flocculation, ozonation, granular activated carbon biofiltration, and disinfection by chloramine. New regulations and the recent economic crisis pushed the facility to investigate methods to decrease costs and meet regulatory requirements easier. The two major issues identified as priorities for investigation were the optimization of the biofiltration system and the use of a novel process to reduce the formation of bromate during oz

Abstract:

Chlorine dioxide (ClO₂) was included in the Spring Hollow Water Treatment Plant (Roanoke County, Virginia) to oxidize manganese and iron, prevent tastes and odors, and avoid the formation of excessive halogenated disinfection by-products. A state-of-the-art, gas:solid ClO₂ generation system manufactured by CDG Technology, Inc. was installed at the plant and is the first full-scale use of this technology in the world. The ClO₂ generator produces a feed stream free of chlorine, chlorite ion (ClO₂⁻), and chlorate ion (ClO₃⁻), resulting in lower by-product concentrations in the treatment system

Abstract:

Water treatment residue (WTR), a by-product of the water treatment process, consists primarily of precipitated hydroxides of the coagulants used in the water treatment process, along with sand, silt, clay, humic compounds, and dissolved organic matter. It is usually disposed of by landfill, a technology with numerous problems that include dwindling landfill capacity, extensive dewatering requirements for the WTRs, high costs of transportation, and potential liability for landfill clean-up. Therefore, land disposal (or land treatment) presents a popular alternative disposal method based on the

Abstract:

Water treatment residues (WTRs) are the by-product from the production of potable water. They consist mainly of the precipitated hydrous oxides of the treatment chemicals, and materials removed from the raw water. This study investigated the range of treatment processes and residues produced in South Africa, and two WTRs were selected for testing on selected soils and mine materials. A questionnaire was developed and sent to water treatment authorities across South Africa. Information on the treatment chemicals, dosages, volumes and current disposal practices, and a sample of WTR from each tre

Countries such as Canada have set the drinking water standard for aluminum content. The United States Environmental Protection Agency included aluminum in the list of National Secondary Drinking Water Regulations, of which many states have implemented. Currently, Taiwan does not include aluminum as a regulated parameter in the drinking water standards. The Shan-Shang water purification plant treats raw water ob

According to the statistical data, the probability of raw water turbidity lower than 15 NTU in Ping-Jan Water Treatment Plant was 63%. However, raw water turbidity might higher than 10,000 NTU due to typhoon events. By changing the location of collecting raw water, the probability of turbidity over 10,000 NTU reduced from 4 to 1%.

The impact of drinking water containing aluminum caused a great concern because of its impact on human health. Government regulations increase the drinking water standards especially in Taiwan. Taiwan Water Corporation is currently active in the improvement of water purification plants for each region and reduction of aluminum content in drinking water.As a result, alternative method was used for the water purification.Instead of using an aluminum based
