Utilización de columnas verticales de filtración de manta y arena como pre-tratamiento de un sistema de filtración lenta
(2012-07-09)
Slow sand filtration is an efficient water treatment technique used for treating surface water with relatively low levels of contamination. Despite the slow sand filtration at pathogen, algae and cyanobacteria removal ...
Removal of anti-inflammatory compounds by ecological filtration
(Iwa Publishing, 2014-01-01)
The use of the slow sand filtration, better known as ecological filter was tested to removal of anti-inflammatory compounds from water, (i.e. Diclofenac, Naproxen and Ibuprofen). The treatment system consisted of pre-filtration ...
Perdas de carga em filtros rápidos de fluxo ascendente e descendente
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Civil, 2018)
The following study of the head loss in filters, whether of upstream or downstream flow, is of main importance in the projection and mainly in the operational control of such units in a water treatment plant (WTP). However, ...
The challenge of improving the efficiency of drinking water treatment systems in rural areas facing changes in the raw water quality
(2021)
Safely managed drinking water for all is the United Nations Sustainable Development Goal 6.1. Achieving this goal is a challenge in rural areas. A strong partnership between users of a water treatment system was critical ...

(Academic JournalsVictoria IslandNigéria, 2010)
Optimization of water use in a rapid filtration system: a case study
(2020)
The objective of this research was to reduce water use during the operation of anthracite-sand filters used for treating drinking water. The variables that affect the saturation of the filter bed were evaluated, using ...
Removal of color in water supply using electrolytic process and direct filtration
(Univ Catolica Pereira, 2017-01-01)
In this research the color removal through electrolytic process, followed by direct filtration with six different doses of Al-2(SO4)(3) for the Parana river potabilization in Ilha Solteira-Sao Paulo was evaluated. The ...
Desempenho de sistema de dupla filtração para clarificação de água
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Ambiental, 2019-11-12)
With the frequent difficulty both due to lack of water availability and quality, new treatment technologies aimed at ensuring water quality in supply and better use of water resources have been the target of research and ...
Occurrence of PPCPs in a Brazilian water reservoir and their removal efficiency by ecological filtration
(2019-07-01)
The presence of PPCPs (Pharmaceuticals and Personal Care Products) in water sources and drinking water has concerned researchers in recent times. This study was carried out to evaluate the occurrence of 6 PPCPs (namely ...
