Literature Review on the Open Pond Sewage Paper
Mission and objectives
Morobe Development Foundation Inc. is a leading Community based Group base in Lae Morobe Province, Papua New Guinea who has the vision to help young people reach their full potential by utilizing their hidden talents in community development initiatives so they can realize their potentail and become a role model in the community. MDF was established to address a broader and more diverse range of objectives and work through the use of dance, music and drama, MDF’s primary aim is to ensure that women participate equally in decision making in any project undertaken, including projects related to Ending Violence against Women, and promoting Human Rights with a aim to support the Government and UN their Development Goals. MDF in collaboration with the United Nations Volunteering Program (UNVP) has also undertaken various scientific research studies related to the environment - forest cover loss, land use land cover change, the influence of various parameters on surface waters, and coastal shoreline turtle habitat loss. These projects included the participation of various experts and researchers from diverse fields across various countries across the globe - ranging from marine biology, biodiversity conservation, PNG community management, remote sensing, and land use policy among various others. MDF is managed by a management committee, which is made up of the Chairman, the Deputy Chairman, Secretary, the Treasurer, the Project Coordinator, Community Development Officer, and a male and female member of the foundation, and ensures that women participate equally in decision making. We at MDF assert that we have the required skill sets, knowledge, established international network, and the necessary foundational work to undertake projects successfully.
The production of waste is inevitable, and a considerable amount of the waste produced through anthropogenic activities end up as wastewater. Wastewater, which is generally categorized as either domestic or industrial, contains dissolved and suspended organic/inorganic contaminants, which can be removed through biological means. Wastewater management has become a major challenge in developing countries due to increased population growth, industrialization, urbanization, low levels of awareness, as well as poor technical knowledge. Wastewater stabilization ponds (WSPs) are used worldwide to treat wastewater. This is because they are cost-effective (in both construction and operation), and require less mechanical equipment, less skilled labour, and less maintenance during operation. WSPs can be single or multiple man-made bodies of water, examples of which include anaerobic, facultative, maturation (aerobic), aerated, and high-rate algal ponds. Within WSPs, wastewater and solid waste (septage, solid industrial, agricultural waste, etc.) are treated naturally using solar light, wind, and microscopic organisms such as protozoans and algae and are capable of lowering 90% of biochemical oxygen demand (BOD) and total suspended solids (TSS). The overall aim of this study is to help MDF develop a sustainable method using existing technology to capture sludge at the University of Technology Papua New Guinea WSPs, and to minimize total suspended solids (TSS), microbes and trace elements to EPA standard levels before discharge. This project will achieve the rehabilitation of the Unitech WSPs through the following objectives, i) obtaining real-time information on the ponds and their current wastewater quality, ii) usage of geobag technology to capture, dewater, and pump the sludge into a newly dug adjacent pond for rehabilitation, iii) analysis of polymer and caustic soda treated samples, and iv) analysis of water hyacinth (roots, stems and leaves) to estimate the bioaccumulation of trace elements (As, Cd, Pb, and Hg). The importance of this study and its proposed method is the hope that it will be able to encourage better decision making with regard to heavily contaminated water bodies and provide a more informed method of rehabilitating wastewater stabilization ponds.
MDF is looking for two (2) Online Volunteer(s) who are well versed in sewage pond monitoring and management. The Online Volunteer(s) will assist by carrying out literature review on existing sewage pond papers appropriate for a University of Technology Papua New Guinea and provide advice and recommendation based on findings on sewage pond monitoring, testing and management. The task includes reviewing sewage paper with a number of pages, paragraphs, lines, words and characters as 19, 602, 1,114, 6,168, and 33,362 respectively. Similarly, all volunteers are expected to review the whole paper and provide recommendation based on findings on sewage pond monitoring, testing and management. At the end of this assignment UNV will issued a certificate of appreciation in recognition to the online volunteer's contribution.
