“…Low hydraulic load resulted from the fact that the sewage, which supplied the bed was characterized by the high content of organic substance in comparison with typical municipal sewage for which the trickling filter operating parameters were established [Daigger & Boltz 2011, Ali et al 2017. The average pollutant load of SS VF was 90.9 gO 2 m -2 d -1 for BOD 5 and 115.2 gO 2 m -2 d -1 for COD.…”

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 BOD 5 , 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 BOD 5 m-2 d-1 , 0.57 kg COD m-2 d-1. The load of SS-VF was on average 0.09 kg BOD 5 m-2 d-1 and 0.12 kg COD m-2 d-1. The obtained results of hybrid treatment permitted to discharge the sewage to the receiver.

“…Currently, multifarious methods (i.e., coagulation, ionexchange, chemical precipitation, occulation, bioreactors, photo-catalytic degradation, trickling lters, electrochemical oxidation, activated sludge, adsorption and membrane ltration) have been developed and somehow optimized to treat toxic dyes from water/wastewater. 13,14 Despite this dedication, there is still a demand to remove these hazardous dyes, because most of the tested technologies are not environmentally friendly and are expensive. 15,16 Among them, adsorption is considered comparatively superior in terms of high efficiency, low cost, easy installation and easy operation over other technologies.…”

“…The treatment systems compatibility and combined sewers systems (for domestic and industrial effluents) are also the major problems in the development of WWT systems (Miller-Robbie et al 2017). These problems can be minimized by designing the WWT system according to the characteristics of existing wastewater streams, intended use of treated wastewater and receiving environmental conditions (Ali et al 2017). The suspended growth-based activated sludge WWT is the most conventionally used technology in developed and industrialized countries for removal of dissolved organics.…”

“…However, it is required to enhance the quality of treated effluent when required additional removal of carbonaceous and nitrogenous compounds and pathogens to meet strict permissible limits (Zhu and Rothermel 2014). It was also observed that these systems fail to provide desired level of treatment efficiency at low or high temperature conditions (Ali et al 2017). So, hybrid trickling filter systems are needed to correlate the microbial dynamics structure with organics digestion, nitrification, denitrification and phosphorus removal.…”

Optimization of operational parameters of wastewater treatment system using the modeling technique may lead to enhance the system's operational and treatment efficiency. The present research was carried out to investigate the treatment efficiency of conventional trickling filter (CTF) and cascade cum trickling filter (CCTF) for treatment of domestic wastewater. Both the systems (CTF and CCTF) were operated for a period of four months under temperature range of 21-48 °C. The maize cob (MC) and date palm fibre (DPF) were used as biofilm support media. Biological oxygen demand (BOD) reaction kinetic model was developed and evaluated for optimization of BOD removing efficiency of CTF and CCTF. The removing efficiency of CTF and CCTF has increased with increasing operational time from 12 to 48 h. The CCTF showed 3-25% higher efficiency in removing organic matter, nutrients and sulphates compared to CTF regardless the supporting media. Similarly, MC showed 3-8% higher removal efficiency of the tested parameters compared to the DPF as supporting media in both CTF and CCTF systems. The BOD reaction kinetic model estimated the optimal volumetric design BOD loading rates (Bvd) of 1.5-2.1 kg BOD/m 3 day for designing efficient trickling filter systems. The CCTF with MC media was found efficient than other reactors due to highest BOD removal efficiency (91.8%) and good capacity to treat high BOD load (2.1 kg/m 3 . day). Hence, the CCTF system has higher potential for efficient removal of organic and inorganic contaminants from the wastewater in developing countries.
