Advanced wastewater treatment processes for groundwater recharge,especially processes to remove organic contaminants from secondary effluent of a sewage treatment plant were studied in this research.When the raw water was recharged directly through surface percolation without advance treatment,effluent of the...
In Nordic countries, on-site wastewater treatment systems (OWTS) are mostly used in sparsely populated areas and are regulated for the removal of phosphorus (Tot-P), organic matter (biological oxygen demand, (BOD7)) and total nitrogen (Tot-N). However, available reports, albeit commonly using...
发明人: PB Clark 摘要: A wastewater or effluent treatment apparatus comprising at least two adjoining compartments, means for fluid flow regulation between the compartments, an inlet and an outlet, wherein at least two of the compartments have different plan areas.收藏...
Therefore, the application of treated wastewater for agricultural irrigation has much potential, especially when incorporating the reuse of nutrients like nitrogen and phosphorous, which are essential for plant production. Among the current treatment technologies applied in urban wastewater reuse for ...
In the Netherlands interest in advanced treatment is increasing now that almost all wastewater treatment plants apply full biological treatment and nutrient removal. Membrane filtration of WWTP-effluent appears to be a very promising method to remove suspended solids and, in addition, bacteria and virus...

Wastewater treatment plant (WWTP) effluent has been identified as a potential source of microplastics in the aquatic environment. Microplastics have recently been detected in wastewater effluent in Western Europe, Russia and the USA. As there are only a handful of studies on microplastics in wastewate...
Results also showed that the increase of some of the undesirable parameters was not related to the operation of wastewater treatment plant. Therefore, in order to make the standard effluent, different methods may be proposed and the most practical and economical one is dilution by using 50% ...
The main purpose of this survey was to determine whether the Wisconsin Rapids Wastewater Treatment Facility, a POTW could accommodate the additional water usage and contaminant loadings that would be introduced as a result of this proposed processing plant. Also, other factors, such as water usage,...
