Abstract
Most of developing countries often suffer from the absence of efficient institutions; lack of technological knowledge and empirical Know-How of wastewater treatment processes and their implementation; also inappropriate management practices. Trying to get some solutions of the wastewater problems in those countries, Natural Oriented municipal Wastewater Treatment and Reuse concept (NOWTR) will be implemented as a naturally oriented low cost technology for wastewater treatment and re-use, where the wastewater will be anaerobically treated using a natural UASB pond reactor (UCY Pond Type UASB-reactor) to win all of the anaerobic treatment benefits as winning of biogas as an alternative source of energy as well as less quantity of sludge with a very good stabilization status, and cost effective benefits as low capital, operation and maintenance cost. The treated wastewater will be naturally disinfected in polishing/disinfection pond at low cost manner by means of sunlight, then the produced disinfected treated wastewater will be re-used for the agriculture purpose as a potential to recovery of the high valuable nutrients in wastewater like Nitrogen, Phosphor, and Potassium which have an effective value for soil reclamation and its productivity improvement. Also the NOWTR Concept include an effective solutions of safe sludge hygienization and drying for disposal and/or re-use as a fertilizer to improve the soil reclamation.
