TL;DR: Low cost, scalable, air cathode bio-electrochemical reactor, constructed by adopting a trickling filtration approach (TrickBER) and operated in continuous mode, was found suitable in simultaneous electricity generation during continuous wastewater treatment and, in the future, could be used in small/cottage industries.
Abstract: Bioelectrochemical systems such as microbial fuel cells are novel systems; those directly transform the chemical energy contained in organics of wastewater into electrical energy by the metabolic a...

TL;DR: In this article, a bio-trickling filter system for removing odor and VOC (volatile organic compound)s is provided to improve removing efficiency of bad smell and V OCs by improving problems of excessive growth of bacteria and pressure loss.
Abstract: PURPOSE: A bio-trickling filter system for removing odor and VOC(volatile organic compound)s is provided to improve removing efficiency of bad smell and VOCs by improving problems of excessive growth of bacteria and pressure loss. CONSTITUTION: A moisture provider provides moisture to air and polluted gas. A simple mixing chamber comprises a filling unit and a mixing chamber. Bacteria and nutrient source are provided to each mixing chamber. Injection devices like spray nozzle induce decarbonization. A biofilter having bacteria attached to adsorbent removes the polluted gas.

TL;DR: In this paper, the authors investigated the treatment efficiency of conventional trickling filter (CTF) and cascade cum-training filter (CCTF) for treatment of domestic wastewater for a period of four months under temperature range of 21-48°C.
Abstract: 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/m3 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/m3.day). Hence, the CCTF system has higher potential for efficient removal of organic and inorganic contaminants from the wastewater in developing countries.

TL;DR: In the early 1900s, two continuous processes were developed to increase the amount of wastewater that could be treated and decrease problems associated with clogging, and these processes continue to dominate wastewater treatment systems to the modern day.
Abstract: Microbiological systems for the treatment of wastewaters were developed around the late 1890s,
initially for treatment of human waste and later for treatment of industrial wastes. The first treatment
systems were run in “batch mode”; wastewater was held in reactors containing rocks. Although the
microbial nature of the process was not clearly understood initially, it is now known that microbes
grow in biofilms attach to the rocks, utilize carbon and nitrogen compounds in the waste as a food
source, and thus reduce the oxygen demand the wastewaters would exert when released to the
environment. To increase the amount of wastewater that could be treated and decrease problems
associated with clogging, two continuous processes were developed in the early 1900s — trickling
filters [1] and activated sludge [2]. These processes continue to dominate wastewater treatment
systems to the modern day.
