The climatic changes that the middle Moulouya region of Morocco has undergone in recent years, demographic growth and development urbanization have led to a significant decrease reserves water can be mobilized for domestic agricultural uses. This deficit, between availability need water, will only increase with increasing needs consuming sectors. main objective is follow physical-chemical evolu...

Advanced oxidation processes like Fenton and photo-Fenton have been effectively applied to oxidize the persistent organic compounds in solid waste leachate and convert them to unharmful materials and products. However, there are limited data about application of Fenton-like process in leachate treatment. Therefore, this study was designed with the objective of treating municipal landfill leacha...

In this paper, results ofa new sand filter design were presented. The drawer compacted sand filter (DCSF) is a modified design for a sand filter in which the sand layer is broken down into several layers, each of which is 10 cm high and placed in a movable drawer separated by a 10 cm space. A lab-scale DCSF was designed and operated for 330 days fed by synthetic grey water. The response of draw...

Water is one of the world’s most valuable resources. However it is under constant threat due to urbanization, explosive population growth and pollution. The most promising efforts to stem water crisis are to treat the wastewater in a sustainable way and reuse for non-potable applications. Grey water (GW) being highly voluminous and relatively less polluted, recycling for non-potable uses like u...

introduction:expensive chemical tests are usuallyapplied to control the efficiency of wastewater treatment plants. however, the cost of measuring these parameters is one of the challenges of the wastewater treatment plants. using statistical methods has been evaluated for possibility of calculating expensive parameters by measuring the inexpensive parameters in this study. methods:initial sampl...

The state-of-the-art paper packaging biorefinery utilizes cellulose fibrous material from paddy straw and papaya latex to produce products. This in turn generate wastewater with high organic matter content that if disposed without treatment will pollute water bodies affect aquatic life below water. Therefore, comply “clean sanitation” (SDG 6) “life water” 14), this study assesses the efficacy o...

conclusions with the proper operation of wastewater the treatment plant and increasing the retention time, the removal efficiency of the detergents increased. in addition, according to the environmental standards for bod5, cod and the detergents, the results of the present study indicated that the outputs of these parameters from the sbr system were appropriate for agricultural irrigation. resu...
