• Abstract

  Cyanobacteria are former organisms of blooms in springs of water catchment for human consumption and represent a serious concern for public health because they produce highly hydrosoluble cyanotoxins. The Ordinance Nº2914/2011 of the Ministry of Health banned the use of algaecides in waters used for human supply, because such products cause cell lysis and release high concentrations of mi…

• Abstract

  A protozoan with a high degree of dangerousness and very common in the larger world existing outbreaks is Cryptosporidium spp. And once their oocysts present in drinking water can cause damage to human health and animal. As the chlorination does not guarantee complete inactivation of these organisms is necessary for water treatment plants have effective treatment systems, especially durin…

• Abstract

  The slow sand filtration is a simple and efficient technology of treatment of water to rural and developing communities that lost their viability due to frequent worsening of water supply quality; the increase of amount of impurities in the water to be treated anticipates clogging of filters and reduces the operating time. This technology was recently improve by the use of non woven synth…

• Abstract

  It is proposed the characterization of a new screening experiment for protozoa samples (Giardia lamblia and Cryptosporidium parvum) using chemical probes and delayed fluorescence (DF) measurements, in portable devices able to work in the photon-count mode. The main goal is to distinguish the living from the dead (oo)cysts, when arranged in concentrated samples, and to compare with the res…

• Abstract

  The presence, in water, of organic compounds that present health risks, such as herbicides, has caused great interest in the technique of adsorption by activated charcoal. The activated charcoal (AC) is a microporous adsorbent which can be obtained from a variety of carbonaceous materials, its adsorbent power comes from its large surface area and from the presence of a variety of function…

• Abstract

  The concentration of heavy metals in water supplies has become a great concern of environmental and public health. It can cause serious problems on fauna, flora and humans. There are a lot of treatment options for heavy metals removal; nevertheless most of them present the disadvantage of requiring a chemical compound or a high technology process. In other hand there is the biosorption, a…
