This has increased the risk of water pollution and reduced the quality of surface water, resulting in a shortage of clean water for the daily lives of people in the province. The article has studied the application of the MIKE11-ECOLab model and correlation analysis method to assess the current situation of the wastewater receiving capacity of the central river system in Nam Dinh province. At the same time, it also analyzes and predicts the wastewater receiving capacity of the central river system in the province according to the trend of socio-economic development.

The inefficiency of wastewater treatment plants (WWTPs) to remove contaminants of emerging concern (CECs) leads to their continuous release to the environment. Consequently, CECs are present at low concentrations in the treated wastewater (TWW), producing unpredicted and unwanted effects on living organisms as they are discharged into water receiving bodies.

Surface water from rivers plays a significant role in socio-economic development in Ca Mau province. It supplies freshwater for agriculture and aquaculture. Faced with the pressures of development, surface water quality in Ca Mau province has been being at stake. The aim of this paper was to assess the water quality status and wastewater receiving capacity of the main rivers of Ca Mau province.

A study was carried out from December 2016 to February 2017 with the aim of evaluating the effects of some coagulants (Aluminium sulphate, Moringa, Starch) on the effluent discharge of the Etoudi slaughterhouse and the Ako’o River which receives these waste products. Monthly water samples surveys were carried out on these two zones and physico-chemical analysis were done following the recommendations of Rodier and his collaborators.

To Lich River is well-known as a main drainage river and plays a vital role to the landscape distribution of Ha Noi city, which is currently polluted due to improperly untreated wastewater flow. Thanks to QUAL2K model, the variation of the river water quality has been forecasted by 4 particular scenarios. In the first scenario, the whole generated wastewater along To Lich River is not totally collected and treated. Scenario 2 is similar to scenario 1 except that To Lich River receives an addition of diluted water of 5 m 3 /s from Red River.

Every day, up to 750,000 cubic meters of wastewater in Ha Noi metropolitan areas is discharged directly into rivers and lakes, of which only 10 % is treated to the Vietnamese standards. According to the water drainage development master plan for the capital city of Ha Noi until 2030, the government aims at dealing with flood control and improving environmental sanitation for local residents.

Wadi El Raiyan is a great depression located southwest of Cairo in the Western Desert of Egypt. Lake Qarun, located north of the study area, is a closed basin with a high evaporation rate. The source of water in the lake is agricultural and municipal drainage from the El Faiyum province. In 1973, Wadi El Raiyan was connected with the agricultural wastewater drainage system of the Faiyum province and received water that exceeded the capacity of Lake Qarun. Two hydrogeological regimes have been established in the area: (i) higher cultivated land and (ii) lower Wadi El Raiyan depression lakes.

Industrial wastewaters from pig slaughtering plants (PSPs) generated in the slaughtering process could have an environmental impact, if discharged to a receiving water body without any treatment. In this study, a Chilean Thraustochytrid (TH) strain, a class of marine protist, was used for the bioremediation of piggery slaughterhouse wastewater (SWW). According to the physicochemical analysis of the residue, it was characterized by an initial chemical oxygen demand (COD) of 9610 mg L 1 , 18,625 mg L 1 of oil and grease, 1639 mg L 1 of total nitrogen, 149 mg L 1 of total phosphorus, and 82.

Oily wastewater discharged from machinery producing, mining, storage service, marine transporting... is one of the polluting sources to receiving waterbody. Adsorption onto carbonized material derived from agricultural by-products are proved to be the promising treatment for this type of wastewater.

The objectives of Alberta Environment’s approach to setting wastewater release standards are to ensure water quality objectives are maintained, that appropriate pollution prevention and control technologies are adopted so that substance releases to receiving waters are minimized. Two standards are developed to assess the limit that should be applied in an approval: one standard is based on best available technology economically achievable, and the second is based on maintaining water quality objectives. The technology-based standard is the minimum effort required. ...

Utilising spectrum on the digital terrestrial television (DTT) platform means that many localities across the UK will have a chance to receive local TV services. However, this will not be universal given inherent constraints with spectrum and the DTT platform. Instead, localities not reached by local DTT broadcasts will in the future be able to receive local TV through internet protocol television (IPTV) which most set-top boxes and television sets have or will eventually have the capability of receiving.

Another aspect to take into account in assigning priority is the geographical extent of the impact, i.e. whether a particular problem, for example caused by a discharge of wastewater, has only a local impact in an area of a few hundred meters along the river or whether there is an impact in the entire river system downstream of the discharge. The likely answer depends, for example, on the size of the discharge and the retention time in the receiving water bodies, the degradability of the pollutant, and the occurrence of sensitive species in the receiving water body. In addition, the...

The volume of texting among teens has risen from 50 texts a day in 2009 to 60 texts for the median teen text user. Older teens, boys, and blacks are leading the increase. Texting is the dominant daily mode of communication between teens and all those with whom they communicate. The typical American teen is sending and receiving a greater number of texts than in 2009. Overall, 75% of all teens text. Here are the key findings about the role of texting in teens’ lives: The median number of texts (i.e. the midpoint user in our sample) sent on a typical...

Compared to other ecosystems, wetlands have received an exceptional amount of attention. Wetlands are valuable as sources, sink and transformers of a multitude of chemical, biological and genetic materials. They stabilize water supplies, clean polluted waters, protect shorelines, and recharge groundwater aquifers. They have increasingly become recognized for their unique ecological functions in the environment and are the focus of increased research by scientists and study programs by schools, communities, and nature centers.

PBgC’s financial assistance is not automatic. a plan must follow certain procedures to obtain financial assistance. First, it must notify PBgC and the plan’s participants that it is insolvent. Second, it must inform participants of their statutorily guaranteed benefit levels. next, it must apply for financial assistance with the PBgC. PBgC must then verify the insolvency and determine the level of financial assistance it will provide. This level depends on the amount of contributions and withdrawal liability payments the plan is receiving, if any.
