A Combined Vermifiltration-Hydroponic System

Insufficient treatment of hog farm effluents has been reported for common technologies, and vermifiltration is considered a promising treatment alternative that, however, requires additional processes to remove nitrate and phosphorus. This work aimed to study the use of vermifiltration with a downstream hydroponic culture to treat hog farm effluents. A treatment system comprising a vermifilter and a downstream deep-water culture hydroponic unit was built. The treated effluent was reused to dilute raw wastewater. Electrical conductivity, pH, and changes in BOD5, ammonia, nitrite, nitrate, phosphorus, and coliform bacteria were assessed. Plants were monitored throughout the experiment. Electrical conductivity increased due to vermifiltration; pH stayed within a neutral to mild alkaline range. Vermifiltration removed 83% of BOD5, 99% of ammonia and nitrite, and increased nitrate by Citation: Ispolnov, K.; Aires, L.M.I.; 11%. -

NFPA 70®-2020 Edition National Electrical Code® TIA Log No.: 1598 Reference: 406.9(C), Exception No. 2(new) Comment Closing Date: August 23, 2021 Submitter: Kerry Stackpole, Plumbing Manufacturers International (PMI) www.nfpa.org/70 1. Add a new Exception No. 2 to Section 406.9(C) to read as follows: 406.9 Receptacles in Damp or Wet Locations. … (C) Bathtub and Shower Space. Receptacles shall not be installed within a zone measured 900 mm (3 ft) horizontally and 2.5 m (8 ft) vertically from the top of the bathtub rim or shower stall threshold. The identified zone is all-encompassing and shall include the space directly over the tub or shower stall. Exception No. 1: In bathrooms with less than the required zone the receptacle(s) shall be permitted to be installed opposite the bathtub rim or shower stall threshold on the farthest wall within the room. Exception No. 2: In a dwelling unit, a single receptacle shall be permitted for an electronic toilet or personal hygiene device such as an electronic bidet seat. The receptacle shall be readily accessible and located on one of the following: (1) The wall behind the toilet but not behind the tank (2) The opposite side of the toilet from the bathtub or shower Substantiation: It is quite common for a toilet to be located next to a bathtub or shower in a residential bathroom. The existing text in NFPA 70 could prevent the installation of a receptacle that is necessary for the operation of an electronic toilet (also known as a “smart toilet”) or personal hygiene device (e.g., electronic bidet seat) where a toilet is located within 3 feet horizontally of a bathtub or shower. -

At that time pit latrines were known for their bad smells and uncontrolled fly breeding. They were both unpleasant to use and posed a serious health hazard. People often preferred to use the bush as a toilet. This may have been OK in remote areas and in the dry season. But in more densely populated areas and during the rains, such a method was undesirable. The Blair Latrine has been used by the Ministry of Health in its rural sanitation programme since 1975. The Blair Latrine was designed and developed at the MOH’s Blair Research Laboratory. The first experimental ventilated pit latrine was built in 1973, and after two years of testing, it became available for use by the Ministry of Health in May 1975. At that time details of this research and development were sent to South Africa and Botswana, where similar toilets were also constructed. Over 500 000 Blair latrines have been built in Zimbabwe since 1975, serving over 3 million people. The Blair Latrine later became known as the VIP (Ventilated Improved Pit Latrine).

The Cultural and Environmental Unsoundness of the Chinese Public Squatting-Type Toilet: a Case Study Toward a Sustainable Excreta Treatment System
Environ. Eng.

According to the adequate environmental management in Yanbian Korean Autonomous Prefecture (YKAP), northern China, this culture may be comfortable to the people of China, yet uncomfortable to the non-Chinese. We conducted a series of field surveys and individual interviews (Chinese n = 1000 and non-Chinese (foreign visitors) n = 100) on several aspects of the public squat toilet: structural properties, waste disposal methods, important factors, and overall satisfaction level. The significant factors in response to the public squat toilets were cleanliness, odor, toilet paper, temperature, soap, other facilities, and presence of cubicles. These factors should be the policy priorities of local government. In addition, 66.2% of Chinese and 91% of foreign visitors desired type E toilets (two full-height partition walls per cubicle, with a door). The results illustrate the nature of a sustainable and aesthetic approach to the culturally and environmentally sound management of various types of public squat toilet in YKAP. The government needs to focus on the future-oriented and excreta treatment management of the sustainable toilet culture for the residents of, and visitors to, YKAP. -

Sustainable Sanitation – a Case Study in Yasmine and Awda Informal Settlements (Lebanon)
Master's Thesis 2019 30 ECTS Faculty of Environmental Sciences and Natural Resource Management Sustainable sanitation – A case study in Yasmine and Awda informal settlements (Lebanon) Elisa Winger Eggen Master of Science in Water and Environmental Technology (M-VM) PREFACE This MSc thesis is my final work of the Master of Science in Water- and Environmental Technology at Norwegian University of Life Sciences (NMBU). The research is based on fieldwork undertaken from the 27th of January until the 3rd of March 2019 in Bekaa Valley, Bar Elias, Lebanon, aimed to find sustainable sanitation solutions in two refugee camps. The study has been carried out in close collaboration with Norwegian Church Aid (NCA), International Orthodox Christian Charities (IOCC) and Multiconsult. My motivation for this thesis was based on a desire to choose a research topic that could be meaningful for others, and my interest in water and sanitation in developing countries. I sincerely hope this will contribute to improvements and implementation of a holistic sanitation system which will benefit the people in the studied camps. Ås, May 14th, 2019 Elisa Winger Eggen I II ACKNOWLEDGEMENTS Working on this thesis has been exciting, challenging and educational. There is a lot of effort invested in the final version of the thesis, and the learning process to this point has been invaluable. Many have contributed to this work, whom I will like to thank; First and foremost, my deepest gratitude goes to my main supervisor, Professor Petter D. Jenssen, for his enormous inspiration, engagement, valuable feedback and support along the way. I would also like to thank Tor Valla (Multiconsult), Ioannis Georgiadis (NCA) and Manfred Arlt (NCA) for introducing me to this project in Lebanese refugee camps, where my education would be relevant and applied in practice.
