In the department of Cauca, around 12, families currently reap the rewards of sisal cultivation. Washing the harvested sisal is a stage in the transformation process that contaminates large volumes of water.

This goes on to reach a natural water source, in this case the Las Margaritas river in Silvia, Cauca. With the above concern in mind, this study puts forward an alternative solution using Common duckweed Lemna minor.

Evaluation of the efficiency of the phytoremediation process on a pilot scale was decreto 3100 del 2003 out through the decreto 3100 del 2003 of such physicochemical parameters as BOD5, COD, TSS, nitrogen and phosphorus in the water.

The variable used was hydraulic retention times HRTwhich were eight and twelve days.

Results suggest that percentage removal by Lemna minor was highest with a HRT of eight days, reaching values of Introduction It is widely known that water is one of the most important natural resources for human life, not only for consumption but for carrying out different industrial and agricultural activities.

Decreto 3100 del 2003 very activities, however, are causing significant changes for the resource, resulting in a reduction in the quantity and quality of water available for humankind.

According to a report by the United Nations inColombia decreto 3100 del 2003 ranked 24 in a list of nations in water availability per capita.

Although at first glance it would seem high on the list, it is troublesome because in the late twentieth century it was ranked Number 4 Scientific and Decreto 3100 del 2003 Consultative Forum, A. In Colombia, some agricultural processes, such as the processing of coffee and to an even greater extent, the washing of the fiber of sisal Furcraea bedinghausii ; local names include fique, cabuya and penca.

The washing process demands large quantities of water. Sisal production involves everything from the sowing of the plant to extracting the fiber and is carried out by means of different steps.

decreto 3100 del 2003 These correspond to the cutting, removing the spines, pulping, washing and drying. The process that causes greatest impact to bodies of water is the washing stage, since more than 1, liters of water are required to wash Regarding the use of floating plants for wastewater treatment, various phytoremediation studies have combined to establish decreto 3100 del 2003 characteristics required by aquatic plants for use in wastewater treatment Delgadillo et al.

These include high productivity, high efficiency in removal of nutrients and pollutants, high predominance in adverse natural conditions and ease of harvest Rodriguez et al.

Studies carried out using Lemna minor show that it meets all decreto 3100 del 2003 these requirements and because of this has been widely used in wastewater decontamination systems Arroyave, Furthermore, good results were observed in research using Lemna minor as having great potential for the removal of cadmium, selenium and copper in contaminated wastewaters with these elements Zayed, ; likewise in the treatment of wastewater from pig farms in the Cauca Valley a decrease was reported in the biological oxygen demand along with a reduction in total suspended solids Chara, Up until now, despite searches of different scientific publishing media, no studies have been found that evaluate the use of duckweed as an alternative treatment for wastewater from washing sisal.

With all this in mind, the present study proposes an alternative treatment for wastewater from sisal fiber washing using aquatic plants since, as mentioned above, they are considered as an efficient and economical alternative National Planning Department, DNP, To carry out the biological treatment, a pilot trial was conducted at decreto 3100 del 2003 study site that took the wastewater from sisal washing in the village of Valle Nuevo in the municipality of Silvia Cauca decreto 3100 del 2003 the site was chosen because wastewater there is currently pouring into the Las Margaritas river, without any treatment, causing direct pollution, and some characteristics of eutrophication can be seen.

The effect of hydraulic retention times HRT of 8 and 12 days on the efficiency of removal of biochemical oxygen demand BOD5chemical oxygen demand CODtotal suspended solids TSSnitrogen and phosphorus was evaluated.

Methodology To decreto 3100 del 2003 the project objective, a sisal fiber producing farm was selected in the municipality of Silvia, Cauca, and a pilot plant Figure 1 was built on-site. Sedimentation time was similarly determined, in order to consider a primary treatment in the decreto 3100 del 2003 test assembly, specifically in tank 1 with a liter capacity Figure 1which would make it possible to control the presence of sedimentable solids present in this kind of wastewater, which eventually could be used in a composting process.

Sedimentation efficiency was calculated using a sedimentability curve, shown in Figure 2and applying Equation 1 Perez,where: Diagram of pilot plant Figure 2. Tank height and Vs: Once the settling time was established, the flow rate to be used in the trial decreto 3100 del 2003 determined.
