Opis:: Textile industries are among the most environmentally unsustainable businesses, releasing large amounts of effluent that endangers ecosystem health. Constructed wetlands (CWs) are low-cost eco-technical treatments for industrial wastewater control. The CWs are self-contained remediation systems that do not require external energy and have basic mechanisms for pollutant removal, such as biological, chemical, and physical processes. For more than sixty years, constructed wetlands have been utilized to clean wastewater. Most applications have been developed to treat municipal or household wastewater, although CWs are now successfully used to treat a wide range of wastewater types. Constructed wetlands were also employed to treat textile industry effluents in the 1990s. The survey indicated that textile manufacturing wastewaters were treated using subsurface and surface-flow wetlands. Both horizontal and vertical flow systems have been designed within subsurface flow-created wetlands. In addition, many hybrid-built wetlands have recently been documented in the literature for textile industrial wastewater treatment. According to the survey, textile industrial wastewater is treated in constructed wetlands on all continents, and this research includes the data from 65 constructed wetlands in 21 nations worldwide. This paper examined the latest improvements and discoveries in CWs and the many types of CWs used for textile wastewater treatment. The paper also demonstrated state-of-the-art integrated technologies for improving the performance and sustainability of CWs, such as CW-MFC systems.

Opis:: Pollutant removal by the mechanism of constructed wetland has led to low cost, highly efficient wastewater treatment technology. Constructed wetlands (CWs) are artificial engineered systems that mimic like natural wetlands. CW’s have been used in previous research to treat a broad range of waste streams at large-scale for low-cost application in wastewater management. Generally, the most literature has targeted a particular class of mechanism or the other due to lack of generalized techniques for wastewater management using CWs. This work focuses on to introductory information and review on concept of CWs based on the latest mechanisms for the wastewater treatment to inspire economical and sustainable solutions to water based environmental problems. This research emphasis CW mechanism, construction, design, and applications of CWs as well as optimization of CWs for the treatment of wastewater. This review also highlights the study with different treatment stages of CWs for removing pollutants from different types of wastewaters.

Opis:: Increasing the demand for potable water, followed by the high quantity of discharged effluents linked with the water scarcity problems has necessitated giving more attention to improving wastewater treatment processes and operations. The constructed wetland has proven to be an excellent green sustainable technique for purification. This study aimed to examine the performance of four experimental free water surface constructed wetlands (FWSCWs) for the depuration of sewage effluents as a secondary treatment stage during winter season conditions. The objectives were to assess the raw and treated wastewater concentrations, evaluate the removal efficiency of chemical oxygen demand (COD), biological oxygen demand (BOD), nutrients, and total suspended solids (TSS) of each treatment line, and compare the impact of plastic rings (biofilm carriers) and Lemna minor L. with the presence of gravel bed on the treatment efficiency and bacterial growth, as well as assess the plant’s adaption and growth. The results showed that all treatment systems improved the water characteristics, and adding biofilm carriers enhanced the efficiency of water purification, especially BOD reduction. The combination of the plants, biofilm carriers, and gravel in the wetland filter significantly enhanced (ρ < 0.05) the treatment efficiency in terms of TSS, COD, BOD, Ammonia (NH3), Nitrates (NO3), and Orthophosphate (PO4) compared to the control treatment system (gravel bed). Plant growth was restricted in the presence of carriers in the system. Further study for examining the system performance under summer conditions, which may improve the nutrient reduction rates by biofilm carriers, is underway.

Opis:: Constructed wetland is considered an alternative for domestic wastewater treatment in cities. This study serves to evaluate the removal capacity and kinetics of TSS, COD, phosphate, and surfactant in domestic wastewater with several plants of Cyperus alternifolius, through the use of the constructed wetlands treatment. The overall objective of the study was to determine the ability of Cyperus alternifolius to remove water pollutants in domestic wastewater in several plants. The domestic wastewater was contacted in a batch system. The results indicated that CWs had a good performance on COD, phosphate, and surfactant with removal efficiencies of more than 80%, with a retention time of 8 days and 5 plants. However, the removal of suspended solids was found limited, as shown that the TSS removal efficiency was under 40%. The first-order equation of kinetics described the degradation of pollutants. The q1/2 values, which were defined as the average removal loading prior to the half of the pollutant concentration being removed and represented the removal capacity without limitation of pollutants concentration, were moderately increased with an addition to the number of plants.

Opis:: This study aimed to assess the efficiency of Nerium oleander in removing three different metals (Cd, Cu, and Ni) from simulated wastewater using horizontal subsurface flow constructed wetland (HSSF-CW) system. The HSSF-CW pilot scale was operated at two hydraulic retention times (HRTs) of 4 and 7 days, filled with a substrate layer of sand and gravel. The results indicated that the HSSF-CW had high removal efficiency of Cd and Cu. A higher HRT (7 days) resulted in greater removal efficiency reaching up to (99.3% Cd, 99.5% Cu, 86.3% Ni) compared to 4 days. The substrate played a significant role in removal of metals due to adsorption and precipitation. The N. oleander plant also showed a good tolerance to the uptake of Cd, Cu, and Ni ions from water. The highest removal of the heavy metals indicated that the HSSF-CW would be a promising technology for heavy metal contaminated wastewater as well as in electroplating and manufacturing industries.

Opis:: High effectiveness of organic pollutants and nutrients removal is achieved in biological wastewater treatments plants – in case of proper exploitation of these objects. Nitrogen and phosphorus transformation or removal depends on many physic – chemical and biochemical conditions, deposit and environmental factors. A rule for treating wastewater consists in decomposition of organic compounds included in wastewater in water-soil environment. Removing contaminations is performed as a result of sorption of contaminations, bio-chemical oxidation-reduction reactions and biological activity of soil microorganisms and hydrophyte flora. The research has been carried out in the constructed wetland in Małyszyn (1300 EP). The treatment plant operates in horizontal system, with under-surface flow of wastewater.

Opis:: In Poland, as well as worldwide, an increase in craft beer production can be observed. In the last several years, more than 150 of such breweries have appeared and according to Polish Brewery Association, their number might ultimately reach 500. Many of them emerge in the areas with no access to a central sewerage system so they have to solve the problem of waste management on their own. The article presents the results of research on the possibility of using a hybrid system for biological treatment of sewage from craft breweries. The sewage came from a craft brewery Waszczukowe located in the Podlaskie province. A laboratory scale model consisted of a trickling filter (TF) (research model Gunt CE701e) and vertical flow constructed wetland (SS-VF). Innovative filling (Certyd produced by LSA company) of TF and SS VF was applied. The conducted study included determining the changes in the sewage parameters during hybrid treatment, as well as TF and SS VF efficiency separately. The aim of the research was to show the possibility of treating sewage to a point when it was possible to discharge it to a receiver, in compliance with the Polish legal regulations. The research results might be used in designing a treatment system or sewage pretreatment in craft breweries. The average efficiency of TF operating with 100% recirculation was 76% for BOD₅, 80% for COD, 26% for TN and 34% for TP, while the total treatment efficiency of a hybrid system (TF and SS-VF) was 98%, 98%, 72% and 77%, respectively. The load of TF during operation with recirculation was on average 0.38 kg BOD₅ m^-2d^-1, 0.57 kg COD m^-2 d^-1. The load of SS-VF was on average 0.09 kg BOD₅ m^-2 d^-1 and 0.12 kg COD m^-2d^-1. The obtained results of hybrid treatment permitted to discharge the sewage to the receiver.

Opis:: The hydraulic performance of constructed wetlands is often compromised by hydraulic problems. Therefore, the development of an appropriate simulation model to reliably predict how various modifications of bed design and configurations might affect performance will facilitate the design of efficient systems. The aim of this research work is to determine distribution of residence time in a field-scale horizontal subsurface flow constructed wetland with Palm Kernel Shell as substrate. The governing equations of flow in porous media and transport of diluted species were solved using COMSOL Multiphysics 5.3a. The result was validated using experimental data and the model result showed good agreement with a correlation coefficient of 0.99. Alternative wetland designs were assessed for the same flow conditions. The results revealed that a two cell wetland improved short-circuiting flow paths.

Opis:: This paper presents the results of research on the impact of the composition of wastewater discharged from a hybrid constructed wetland wastewater treatment plant on the quality of water in the Urzędówka River, a right tributary of the Wyżnica River. During the years 2011-2013, samples of treated wastewater and water from the river were collected (upstream and downstream of the wastewater discharge point) and subjected to physicochemical analysis and, in 2013, also to microbiological analysis. The study showed that the treated wastewater outflowing from the treatment plant did not have any negative influence on the quality of the water in the receiver. Water from the Urzędówka River met clarity standards for class I waters; only the concentrations of total phosphorus and nitrate nitrogen exceeded the limit values for water clarity class II. The studies have shown that waters from the Urzędówka River upstream of the treatment plant contained a huge concentration of E. coli bacteria, fecal coliform bacteria and fecal enterococci, which indicates the impact of other sources of microbiological pollution.
W pracy przedstawiono wyniki badań dotyczące wpływu ścieków odprowadzanych z hybrydowej oczyszczalni hydrofitowej na jakość wód z rzeki Urzędówki, prawostronnego dopływu rzeki Wyżnicy. Próby ścieków oczyszczonych oraz wód z rzeki (powyżej i poniżej miejsca zrzutu ścieków) do analiz fizyczno-chemicznych pobierano w latach 2011-2013, a do analiz mikrobiologicznych w 2013 roku. Na podstawie wyników badań stwierdzono, że ścieki oczyszczone, odpływające z gruntowo-roślinnej oczyszczalni nie miały negatywnego wpływu na jakość wód odbiornika. Wody rzeki Urzędówki odpowiadały I kasy czystości, jedynie zawartość fosforu ogólnego oraz azotu azotanowego przekraczała wartości graniczne określone dla II klasy czystości. W wodzie z rzeki przed zrzutem ścieków oczyszczonych notowano wysoką liczebność bakterii grupy coli i coli typu kałowego oraz enterokoków kałowych, co wskazuje na oddziaływanie innych źródeł zanieczyszczeń mikrobiologicznych.

Opis:: The purpose of the presented research work was to find out COD fractions in raw wastewater and during treatment with constructed wetland (CW) system. The tests were performed in CW system with average flow of about 4 m³/day. In raw wastewater the highest concentration of fraction in organic suspended solid easy biodegradable (X_S – 250 mg O₂/l) was observed. The same situation was with dissolved organic easy biodegradable matter (SS – 250 mg O₂/l). Lower quantity of non-biodegradable fractions dissolved and in suspended solids were observed (S_I – 27 mg O₂/l, XI – 83.33 mg O₂/l). More than 80% of total COD was as biodegradable fractions (S_S + X). After treatment with CW system the highest concentration was observed for dissolved non biodegradable fraction (SI – 27 mg O₂/l). Lower concentration was for biodegradable fraction in suspended solid (XS – 3.33 mg O₂/l). More than 89% of total COD was in biological non-biodegradable fraction (S_I + X_I).

Opis:: During the last 30 years the increase of interest in low-cost decentralized and small wastewater treatment plants (WWTP) is observed in Europe. For this purpose, sand filters, stabilization ponds, mini reactors with activated sludge, trickling filters and treatment wetlands are used. Among the listed facilities, treatment wetlands (TWs) offer effective and reliable treatment efficiency, being at the same time low-cost and simple in operation. This is a sustainable treatment technology which does not generate secondary sewage sludge. In the paper, design concept and performance of nine TWs constructed in 2009 for single-family households in Kashubian Lake District is discussed. The treatment efficiency of three different TW configurations is compared. The findings of the study provide a basis for future design and implementation of TWs in agricultural areas.

Opis:: Przedstawione w pracy badania dotyczą oceny efektywności działania przydomowej oczyszczalni ścieków ze złożem hydrofitowym w Zwierkach. W ściekach pobranych z poszczególnych etapów oczyszczania wykonano analizy BZT5, ChZT, form azotu i fosforu. Na podstawie uzyskanych wyników stwierdzono dużą skuteczność usuwania BZT5, ChZT, azotu amonowego i fosforanów. W pracy zaproponowano także zastosowanie ekologicznego rozwiązania systemu grzewczego oraz redukcję kosztów poprzez modernizację systemu przygotowania ciepłej wody użytkowej w klasztorze w Zwierkach. Założenie przewiduje wspomaganie procesu przygotowania ciepłej wody użytkowej od kwietnia do września za pomocą systemu solarnego w układzie pośrednim, a tym samym częściowe zastąpienie energii pozyskiwanej ze źródeł konwencjonalnych – w tym przypadku z paliwa jakim jest ekogroszek – energią słoneczną pozyskiwaną przez system solarny.
The study focused on the effectiveness of household sewage treatment plant in Zvierki. Were tested wastewater from the septic tank, the well with a diffuser, from the well of sludge, wastewater after filtration through filter with plants and the receiver of treated sewage – the pond. Checked the ability to remove a treatment with respect to BOD5, COD, ammonia nitrogen, nitrates and phosphates. Based on the results high efficiency removal of BOD5, COD, ammonia nitrogen and phosphate. Unfortunately, there was no reduction of nitrates – there has been a significant increase in this ratio from baseline. After comparing the final values to the limit values defined in the Polish legislation, it was found that the test treatment works in accordance with the requirements except for total phosphorus. Proposed reduction of costs through modernization of the domestic hot water in a monastery in Zvierki. The assumption provides support for the process of preparing hot water from April to September, with the solar system in the intermediate system, and thus the partial replacement of energy from conventional sources – in this case, the fuel which is coal – solar energy produced by the solar system.

Opis:: Constructed wetlands are artificial wastewater treatment systems consisting of shallow ponds or channels which have been planted with aquatic plants, and which rely upon natural microbial, biological, physical and chemical processes to treat wastewater. They typically have impervious clay or synthetic liners, and engineered structures to control the flow direction, liquid detention time and water level. Depending on the type of system, they may or may not contain an inert porous media such as rock, gravel or sand. Constructed wetlands have been used to treat a variety of wastewaters including urban runoff; municipal, industrial, agricultural and acid mine drainage. In this regard’s an attempted has been made to reduce the heavy metal present in waste water.
