“…Potato processing produces wastewaters with high starch content. This material is highly biodegradable, and has been the target of constructed wetlands treatment since 1990 (de Zeeuw et al, 1990). Kadlec et al (1997) discussed the use of pilot-and full-scale CWs to treat potato-processing wastewater (PPW) in Washington and Oregon and provided a basis for future design and construction of full-scale PPW-treatment CWs.…”

Constructed wetlands (CWs) for wastewater treatment are engineered systems that are designed and operated in order to use all natural processes involved in the removal of pollutants from wastewaters. CWs are designed to take advantage of many of the same processes that occur in natural wetlands, but do so within a more controlled environment. The basic classification is based on the presence/absence of wastewater on the wetland surface. The subsurface flow of CWs can be classified according to the direction of the flow to horizontal and vertical. The combination of various types of CWs is called hybrid CW. The CWs technology began in the 1950s in Germany, but the major extension across the world occurred during the 1990s and early 2000s. The early CWs in Germany were designed as hybrid CWs; however, during the 1970s and 1980s, horizontal subsurface flow CWs were mostly designed. The stricter limits for nitrogen, and especially ammonia, applied in Europe during the 1990s, brought more attention to vertical subsurface flow and hybrid systems. Constructed wetlands have been used to treat various types of wastewater, including sewage, industrial and agricultural wastewaters, various drainage and runoff waters and landfill leachate. Recently, more attention has also been paid to constructed treatment wetlands as part of a circular economy in the urban environments: it is clear that CWs are a good fit for the new concept of sponge cities.

“…Healy et al, 2007, recommended an organic load of <6 g BOD 5 m´2¨day´1 for surface flow wetlands [30], but at rates of 10 g¨m´2¨day´1, Healy and Flynn (2011) found removals of 95% from primary municipal wastewater and consistently good removals for loading rates of up to 40 g¨m´2¨day´1 [27]. De Zeeuw et al (1990) found that a COD loading rate of 54 g¨m´2¨day´1 had a removal of 48%, while at 12 g¨m´2¨day´1, there was 92% removal from 2000 mg¨L´1 industrial potato wastewater [31,32]. Therefore, increasing the size of the wetland could also increase the BOD 5 removal of our wastewater.…”

Many potato processors require on-farm washing of potatoes, creating large quantities of wastewater that requires treatment, starting in the fall until the end of the potato storage period in mid-summer. We studied the treatment of wastewater from a potato farm in Ontario, Canada, using a system of pretreatment (sedimentation, aeration) followed by a surface-flow wetland with a dense growth of cattails (Typha sp.). The raw wastewater had high average concentrations of 5-day biochemical oxygen demand (BOD 5 ; 1113 mg¨L´1), total suspended solids (TSS; 4338 mg¨L´1), total nitrogen (TN; 311 mg¨L´1) and total phosphorus (TP; 42.5 mg¨L´1). Due to high influent loads, the pretreatment was enlarged during annual sediment cleaning at the end of Year 1 (Y1), which increased the hydraulic retention time and delayed the seasonal onset of wetland loading from winter in Y1 to spring in Year 2 (Y2). Total concentration reduction for the treatment system (pretreatment + wetland) in Y2 was 96% BOD 5 , 99% TSS, 86% TN and 90% TP; and in Y1 was 79% BOD 5 , 97% TSS, 62% TN and 54% TP. Overall, the best treatment in both the pretreatment and the wetland was seen in spring months. The enlarged pretreatment system enabled seasonal loading of the wetland during the spring and summer, which facilitated improved treatment performance.
