“…Since then, James et al [102] tested SW as an amendment material for peat and sand beds in order to: (i) increase the performance for phosphate removal and (ii) lengthen the service life of such beds. The evidence that SW amended peat/sand beds are sustainable systems for phosphate removal was subsequently described some 15 years later by Erickson and colleagues [117][118][119].…”

“…Admittedly, some relevant peer-reviewed articles have been overseen by the used search procedures [151][152][153][154][155][156][157][158]. Academic thesis [117], technical reports [159,160] and patents [161] do exist as well but are not considered herein because they have also not specified key issues addressed in this review. This section will corroborate the argumentation from Section 4.2 by giving a short comment on each table.…”

“…SW was chosen as a suitable Fe 0 material because of its wide commercial availability at relatively low cost and its high surface area with little resistance to fluid flow [102,118,149]. Due to the high levels of variability of both steel wool (SW) samples and contaminated water sources, only a systematic sequence of experiments can determine whether a SW specimen is suitable for water defluoridation.…”

“…The next section will discuss methods to test commercially available SW [117][118][119]132,133] as a suitable fluoride filtration technology. If this operation is successful, such filtration systems will be able to be manufactured in the developing world using commonly available tools [39,78,79,81,85,134,135].…”

“…Here, iron oxides are progressively generated in the system [102,[116][117][118][119], making the efficiency of a Fe 0 filter highly dependent on its physical design (e.g., Fe 0 reactivity, filter bed length, flow velocity). As a sinuous and tortuous material with, therefore, significant intrinsic porosity (available voids which can be used to accommodate the expansive Fe 0 corrosion products), steel wool (SW) can be considered a suitable candidate for use as a filter material [73][74][75]90,120,121].…”

Since the realization in the 1930s that elevated fluoride concentrations in drinking water can have detrimental effects on human health, new methods have been progressively developed in order to reduce fluoride to acceptable levels. In the developing world the necessity for filtration media that are both low-cost and sourced from locally available materials has resulted in the widespread use of bone char. Since the early 1990s metallic iron (Fe 0 ) has received widespread use as both an adsorbent and a reducing agent for the removal of a wide range of contaminant species from water. The ion-selectivity of Fe 0 is dictated by the positively charged surface of iron (hydr)oxides at circumneutral pH. This suggests that Fe 0 could potentially be applied as suitable filter media for the negatively charged fluoride ion. This communication seeks to demonstrate from a theoretical basis and using empirical data from the literature the suitability of Fe 0 filters for fluoride removal. The work concludes that Fe 0 -bearing materials, such as steel wool, hold good promise as low-cost, readily available and highly effective decentralized fluoride treatment materials.

This paper presents the results of using a pilot-scale-constructed wetland as a tertiary system to simulate the treatment conditions of wastewater effluents from the metal-mechanical industry, aiming to achieve the Brazilian legal standards of phosphorus and nitrogen emission. The macrophytes were placed in 1 m 3 polyethylene tanks, daily estimating the treatment of 2 m 3 of effluents. The effluents were circulated in a horizontal subsurface flow through a porous matrix of thick sand and gravel, in which the roots of the macrophytes of the species Reed (Scirpus sp.) and Cattail (Typha sp.) were fixed. Monitoring of the pilot plant was performed through a battery of physical-chemical and biological analyses. Despite the load variations and operational problems, the system presented a positive degree of pollutant efficiency removal, especially for phosphorus (73% medium), TKN (61% medium), and NH 4 -N (56% medium). Peak results were achieved during the last 3 months of monitoring. The chemical analysis of the support layer, plus the root system and aerial portion of the plants, revealed that these wastes could be used as fertilizer.
