Opis:
The present paper discusses the quality fluctuations of leachate from municipal landfill in Gdansk (Poland) over the last 5 years and the evaluation of a wetland system designed for treatment of the leachate. The research has been conducted during a 5-year period. The constructed wetland for leachate treatment was built in 2001; it consists of 2 horizontal subsurface flow reed beds, working in parallel. In the period 2005–2006 it underwent modernization due to unsatisfactory treatment results caused by bed clogging. After the modernization the treatment effectiveness is satisfactory. The effluent from bed I met Polish outflow standards, while in the effluent from bed II COD, total N and TSS exceeded the required concentrations. In spite of this, pretreatment of leachate (iron removal) should be quickly introduced to protect the system against the reoccurrence of clogging problems.

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.

Opisane w artykule badania prowadzono w okresie pięciu lat. System hydrofitowy zbudowany w 2001 roku do oczyszczania odcieków ze składowiska składa się z dwóch poziomych złóż o przepływie podpowierzchniowym, w układzie równoległym. W 2005-2006 roku wykonano modernizację układu ze względu na problem z zatykaniem się złóż. Efektywność oczyszczania po modernizacji jest zadowalająca, odpływ ze złoża I spełnia polskie normy, natomiast w przypadku złoża II zaobserwowano przekroczenia ChZT i zawiesiny ogólnej. W celu uniknięcia zatykania się złóż należy zastosować wstępne oczyszczanie odcieków.

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 (XS – 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 (SI – 27 mg O2/l, XI – 83.33 mg O2/l). More than 80% of total COD was as biodegradable fractions (SS + 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 (SI + XI).

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:
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.

W artykule przedstawiono opracowanie statystyczne zawartości azotu ogólnego w złożu hydrofitowym oczyszczalni. Wyniki badań materiału filtracyjnego wykazały, że największą zawartością azotu charakteryzowała się powierzchniowa warstwa gruntu do 20 cm głębokości. Kumulacja azotu ogólnego malała wraz z penetracją w głąb złoża oraz w kierunku odpływu ścieków z oczyszczalni.
Removal of nitrogen from constructed wetlands depends on many physic-chemical and biochemical conditions, deposit and environmental factors. The paper contains the results of statistical analysis the accumulation of total nitrogen in the soil. The results of the research have indicated that the highest content of nitrogen was observed in the surface layer of the soil at a depth of up to 20 cm. The content of total nitrogen has dropped with the penetration depth and towards the sewage flow from the constructed wetland.

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:
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:
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.

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.

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.

Problem oczyszczania ścieków bytowych na obszarach niezurbanizowanych należy uznać za aktualny i wymagający rozwiązania w najbliższych latach. W pracy porównano wyniki uzyskane podczas eksploatacji urządzeń (złóż biologicznych z wypełnieniem z tworzyw sztucznych) z pracą obiektów hydrofitowych. Podejmowane działania potwierdzają, że zarówno konstrukcje konwencjonalnych urządzeń mechanicznych oraz nowe konfiguracje systemów hydrofitowych stanowią interesujące rozwiązania dla małych ilości ścieków wytwarzanych na obszarach niezurbanizowanych.
The disproportion between water supply and newly constructed sewer systems have been still increasing. Although, the number of people connected to the sewer system is still increasing but compare other EU countries it is unsatisfying.
