“…Rapid urbanization led to a more concentrated release of wastewaters into the environment, which has significantly impacted humans and wildlife. Organic compounds and nutrients from municipal or industrial wastewater contaminate ecosystems, e.g., rivers, ponds, or even groundwater [1]. Low-cost wastewater treatment utilizing local materials can contribute to addressing this challenge, especially in developing countries.…”

Loofah Sponges as Bio-Carriers in a Pilot-Scale Integrated Fixed-Film Activated Sludge System for Municipal Wastewater Treatment

Fixed-film biofilm reactors are considered one of the most effective wastewater treatment processes, however, the cost of their plastic bio-carriers makes them less attractive for application in developing countries. This study evaluated loofah sponges, an eco-friendly renewable agricultural product, as bio-carriers in a pilot-scale integrated fixed-film activated sludge (IFAS) system for the treatment of municipal wastewater. Tests showed that pristine loofah sponges disintegrated within two weeks resulting in a decrease in the treatment efficiencies. Accordingly, loofah sponges were modified by coating them with CaCO3 and polymer. IFAS pilot tests using the modified loofah sponges achieved 83% organic removal and 71% total nitrogen removal and met Vietnam’s wastewater effluent discharge standards. The system achieved considerably high levels of nitrification and it was not limited by the loading rate or dissolved oxygen levels. Cell concentrations in the carriers were twenty to forty times higher than those within the aeration tank. Through 16S-rRNA sequencing, the major micro-organism types identified were Kluyvera cryocrescens, Exiguobacterium indicum, Bacillus tropicus, Aeromonas hydrophila, Enterobacter cloacae, and Pseudomonas turukhanskensis. This study demonstrated that although modified loofah sponges are effective renewable bio-carriers for municipal wastewater treatment, longer-term testing is recommended.

“…Dalam penelitian ini Moving Bed Biofilm Reactor (MBBR), dipilih dikarenakan menunjukkan potensi untuk efisiensi pengolahan yang tinggi tanpa memerlukan area yang luas atau perlengkapan pengolahan yang rumit (Ødegaard, H., Rusten, B., 1994). Selain itu, MBBR tidak membutuhkan area yang luas menghasilkan lumpur yang sedikit, lebih tahan menerima beban dengan COD yang tinggi, dan tidak membutuhkan backwash secara periodic (Borkar, A., Jensen, S., Bjerg, P., Christensen, T., &Nyholm, 2013). Penelitian sebelumnya telah membuktikan bahwa MBBR mampu mencapai hasil yang mengesankan dalam pengolahan limbah jenis tertentu, seperti limbah domestik rumah makan (Farahdiba et al, 2019).…”

“…Media jenis biocube atau spons memiliki penurunan total nitrogen yang lebih besar karena strukturnya yang berpori, memfasilitasi pertumbuhan biofilm tanpa hambatan. Media ini juga memiliki luas permukaan yang lebih besar, mendukung tingkat nitrifikasi yang lebih tinggi (Borkar, A., Jensen, S., Bjerg, P., Christensen, T., &Nyholm, 2013). Volume media berpengaruh pada luas permukaan media untuk menempelnya biofilm.…”

Leachate is a liquid containing extracted, dissolved, and suspended materials from waste in a landfill. Leachate from Klotok landfill contains pollutant loads that do not meet the water quality standards, necessitating treatment. In this study, parameters considered were COD, TSS, and TN. Anoxic-Oxic Moving Bed Biofilm Reactor (MBBR) was chosen due to its compact footprint, low sludge production, ability to handle high COD loads, and not requiring periodic backwash. Variations including media type, media volume, and Hydraulic Retention Time (HRT) were applied to reduce pollutant parameter concentrations. The experiment was conducted in batch-continuous mode. The derived parameter concentrations yielded promising results using a biocube/sponge media in the reactor, constituting 50% of the leachate volume, with an HRT of 45 hours. Upon continuous operation under the best variations for parameter reduction, COD, TSS, and TN values were achieved as 160 mg⁄L, 132 mg⁄L, and 31.5 mg⁄L, respectively. Meanwhile, the average removal percentages for COD, TSS, and TN were 87%, 50%, and 87% respectively. Additionally, microorganism identification was performed in the anoxic-oxic moving bed biofilm reactor, revealing the presence of microorganisms such as coliforms, Bacillus sp., and Pseudomonas sp.

“…There are several benefits of using biofilm system in wastewater treatment, as compared to suspended growth system (activated sludge for example), such as flexible procedures, smaller space demand, lower hydraulic retention time, increased resilience to changes in the environment, higher biomass retaining period, high active biomass concentration, as well as low sludge production [3,5,6]. The use of biofilm systems also enhances the control of reaction rate and population mechanisms [5,7].…”

A brief introduction of the long history of biofilm-based wastewater treatment is given together with basics of biofilm behavior and mechanisms in removal and transformation of pollutants. Moving bed biofilm reactor (MBBR) principles and applications of such are presented. Advantages and limitations of such solutions are given together with evaluations of emerging MBBR applications. The basis of biofilm processes and biofilm layer classification based on dissolved oxygen gradient is discussed. Organisms grow at the protected surface of the biocarrier where oxygen gradients create aerobic, anoxic, and anaerobic layers allowing simultaneous nitrification and denitrification in one MBBR (nitrification, nitritation, autotrophic, and heterotrophic denitrification). Combination of MBBR with activated sludge, continuous flow intermittent cleaning (CFIC®), and integration with anaerobic digestion increases the potential usage of MBBR for enhanced efficiency and energy recovery and is partly discussed as case studies (COD, ammonium, and solid removal). Biofilm thickness and scaling control can be crucial for MBBR performance. The type of carriers, filling degree, and operational conditions play a major role for process performance; hence, the effect of those parameters is presented.
