“…Interception and biofiltration of surface and subsurface runoff using sedimentation ponds, bottom dams, two-stage ditches, controlled drainage and constructed wetlands (LR MK, 2014) can supplement good agricultural practices to reduce rates of nutrient losses from agricultural lands (Tanner, Nguyen & Sukias, 2005) The same attention should be focused also on water collected at farmyards. Constructed wetlands may play an important role in reducing nutrient loads to receiving waters (Tuncosiper, 2009;Valkama et al, 2017). Constructed wetland is a well-known nutrient reduction measure as it is a low cost (Heistad et al, 2006) and low maintenance technology used for wastewater treatment around the world (Neralla et al, 2000;Vymazal, 2002), lately this measure is also recognized in Latvia.…”

A pilot-scale horizontal subsurface flow constructed wetland was installed at the farm Mezaciruli, Zalenieki county, Jelgava region, in the middle part of Latvia, in August 2014 to improve stormwater quality collected from the farmyard and demonstrate applicability of constructed wetland as a convenient treatment option for contaminated surface runoff. The examined water treatment system consists of a sedimentation pond as a pretreatment plant, a water pump, a water distribution well, and a horizontal subsurface flow constructed wetland with the surface area of 160 m 2 . During the observation period of 27 months (2014 -2016) water quality parameters such as total suspended solids (TSS), nitrate nitrogen (NO 3 -N), ammonium nitrogen (NH 4 -N), total nitrogen (TN), orthophosphate phosphorus (PO 4 -P), and total phosphorus (TP) were monitored and nutrient removal efficiency of the system was examined. Water samples collected at the inlet and outlet were compared. Monitoring results obtained during this study show that on average concentrations of TN and TP were reduced by 22% and 80%, respectively. However, nitrate -nitrogen concentrations on average increased by 10%, as during the time period from June, 2015 to March, 2016 reduction in NO 3 -N concentrations was not observed.

“…Hybrid sub-surface CW system achieved purification and removal INTRODUCTION Constructed wetlands (CWs) have shown their ability to remove large amounts of organic material, nitrogen and phosphorus from wastewater of various origins (Tanner et al, 1995;Tunçsiper, 2009;Justin, et al, 2009;Hilley et al, 2003). They are considered to be cost-effective and simple in design and operation (Hunt et al, 2009).…”

“…According to some authors (Tunçsiper 2009;Tegegne et al 2008;Ouellet-Plamondon et al 2006), it occurs due to lower aeration horizontal flow, because aerobic condition is important for the nitrifying bacteria action to promote nitrification.…”

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.
