Abstract
The production of human-produced wastes is increasing with the growth of the world’s inhabitants. As a result, the sustainable management of huge amounts of waste is becoming an increasingly challenging task. One of these challenges is the solid waste produced by the increasing number of water treatment plants (WTPs). This paper is reviewing and proposing a recycling system which may have a technical and economical feasibility for Oman and GCC. The Proposed Recycling system for dry waste from Water Treatment Plant (WTP) in this paper is expected to be able to operate in Omani operation conditions and GCC. It has been patented as a utility model. The assumed feed for the purpose of presenting economically viable case is assumed to be around 100 tons/day. This assumption could go higher depends on the demand.
Highlights
The quantity of worldwide wastewater has been increasing rapidly in the last decades due to the rapid population growth and, increased water use for various purposes

The published data by National Centre for Statistics and Information (NCSI), GCC Statistical Centre (GCC-STAT) and International Energy Agency (IEA) (IEA, 2019) all assumed that the growing consumption of water and the increased need for freshwater affect electricity production in Oman, which has been growing steadily from 2008 onwards and which is 3 times higher than in the rest of the world
Summary
The quantity of worldwide wastewater has been increasing rapidly in the last decades due to the rapid population growth and, increased water use for various purposes. Tanks with sewage water from residential areas and manufacturing facilities quickly become overloaded, and more sewage treatment plants are needed. If wastewater is not treated properly, it may leach to ground waters The consequence of it is the reduction in quality and quantity of food, reduced plants’ growth and uptake of nutrients, physiological and metabolic processes. Current wastewater treatment plants are not designed to remove micro-pollutants such as antibiotics and antibiotic-resistant bacteria and genes. These biological components might end up in the wastewater treatment plant effluent, as they are not fully removed by current treatment technologies As a result, they may reach surface water, groundwater and potentially, drinking water. In order to assess the available methods for sludge utilization and choose the most suitable one, it is necessary to consider current trends in Oman
