. Because of increased water circulation within a factory, the quantity of the effluents also is reduced. Effective, specialized pre-treatment can be used, sometimes with the regeneration of some substances, which further reduces the pollutant load to the effluent or city wastewater treatment plant....
Transboundary economic value decay was reflected on lower households' annual WTP values for the restoration of the tropical out-of-the-country (US$ 124.15–238.30) than temperate out-of-state (US$ 131.70–256.79) forested watershed ecosystems. Bequest and existence were the non-use value ...
Water that has been treated at the water treatment plant (WTP), situated in the southern part of the city, is transported to the city through several main pipes. These main pipes include: Main line No. “0”, with a diameter ranging from Φ 1200 to 800 mm, made of steel. Mains No....
Agricultural wastewater reuse can be classified into direct and indirect wastewater reuses [13]. Direct wastewater reuse refers to the method whereby irrigation water is supplied directly from the wastewater treatment plant (WWTP), while indirect wastewater reuse is a method where effluent from the WWT...
On the other hand, in the mixed water treatment plant (surface and groundwater) in WTP “Mosina”, backwashings are treated in the coagulation and sedimentation processes [16]. The choice of backwashing management method and the method of their pre-treatment should be selected on the basis of...
WTS was generated during the decanting and filter-washing steps of a water treatment plant (WTP) located in the state of São Paulo (Brazil). The WTP produces approximately 15 m3/s of drinking water [45], comprising the following processes: coagulation, flocculation, decantation, filtration, ...
In the water treatment plant itself, the sludge can be used to assist in the coagulation/flocculation process, allowing savings to be made in the use of the coagulant applied in the WTP [72]. A study carried out in a laboratory setting used material recovered from alum sludge treated with ...
Its supply network starts from Tailem Bend township and extends up to Keith with the treatment plant (WTP) located at the Tailem Bend township. On the way from Tailem Bend to Keith, the Tailem Bend–Keith (TBK) distribution system supplies drinking water in many intermediate locations ...
