The Bremen Overseas Research and Development Agency (BORDA) has a mission to improve the living conditions of disadvantaged communities and to preserve the environment through decentralized sanitation projects. As part of this mission, the Agency has developed modular, decentralized, and cost-effective wastewater treatment service packages that they have termed ‘DEWATS’ – decentralized wastewater treatment systems, which, with the help of funding agencies, are being installed throughout Asia and Africa.
The Lao People’s Democratic Republic is a country surrounded by China, Vietnam, Thailand, Cambodia and Myanmar. In 2005, Lao PDR was below average in establishing sanitation access as compared to other Southeast Asian countries. In a study conducted by a Multiple Indicator Cluster Survey in 2006 (MICS III), it reflected a 44.8% coverage for those with improved sanitation (or 48% cited by the UNICEF/WHO Joint Monitoring Program) as compared to the 67% average for all the Southeast Asian countries. In the same study, there are at least fifty-two percent (52%) of the Lao population without access to sanitation. This data equates to over three million Laotians living without improved sanitation - without an easily accessible, private and safe place to urinate and defecate. Furthermore, the growing population of Lao PDR needs to be taken into consideration while looking at the efforts to increase sanitation coverage.

    Wastewater treatment is a vitally important process. Just ask The Township of Edwardsburgh/Cardinal’s Assistant Chief Water and Sewer Operator, Eric Wemerman. “For a community to keep everyone’s trust, you want to make sure you’re operating a good system.” Eric continues “It’s important for health reasons, when people flush their toilets you need to get that away and be treated so there’s health reasons why we treat everything. And environmental too, because what we...

    The aim of this study was to assess the efficacy and effluent quality of a pilot-scale intermittently aerated and fed, externally submerged membrane bioreactor (MBRes) treating municipal wastewater. The effluent quality of the MBRes was evaluated regarding system ability to comply with the Greek legislative limits for restricted and unrestricted wastewater reuse. The average permeate flux was 13.9 L m−2 h−1, while the transmembrane pressure remained above the level of −110 mbar. Experimental data showed that...

    In this study, anaerobic granular sludge (AGS) was used as a novel adsorbent for hexavalent chromium (Cr (VI)) removal from aqueous solutions. Factor experiments were conducted to find out the effects of different variables on the biosorption process. Among these terms, the impact of three main independent variables (contact time, initial pH and AGS dosage) on the removal efficiency of Cr (VI) was modeled using a well-fitting polynomial equation (R2 = 0.9044), by conducting 20 batch experiments designed by a...

  • Pulse electro-coagulation application in treating dibutyl phthalate wastewater

    Pulse electro-coagulation (PEC) was applied to treat plastic factory wastewater in this study. One representative plasticizer molecule was chosen for the synthetic wastewater: dibutyl phthalate (DBP). Experiments demonstrated that PEC exhibits superior economic efficiency and removal efficiency compared to traditional electro-coagulation in wastewater treatment. Experimental data also indicated that at a given current density, compared with the aluminum electrode, the iron electrode could more efficiently remove...

  • Partially aerated submerged fixed-film bioreactor for simultaneous removal of carbon and nutrients ...

    Influence of aeration rate and COD:N:P (C:N:P) ratio on the performance of an upflow partially aerated submerged fixed film (UP/ASFF) bioreactor for simultaneous carbon and nutrient removal from high-strength nitrogen wastewater was investigated during 6 months. Airflow rates at three levels of 1.5, 3, and 4.5 L/min and C:N:P ratios at four levels of 450:300:10, 450:150:10, 450:100:10, and 450:75:10 were selected as the two main input factors. All experiments were performed at constant chemical oxygen demand...
