The environment pollution becomes a big problem around all over the world, which resulted from many resources like water sanitation, smoke …..etc .To find the solution and to decrease the pollution, the scientist and civil engineering create many methods to treat and reuse the wastewater, one of these treatment process is Trickling filter, which is a biological treatment process. The most widely used design for many years was simply a bed of stones.
Treatment of waste water, in addition to strong management will enhance the public health and environmental, the objectives of this project are: Predict waste water flows of Arraba town, Design waste water treatment plant for Arraba, Decide on optimal reuse of treated wastewater and sludge, and Design a model of T.F.
The methodology was collecting the required data from statistics and documentation from the Municipality of Araba ,in order to be able to design a wastewater treatment plant, that include the dimensions of treatment units, drawing general layout of plant, drawing the profile, and section of the units, also a Trickling filter model was designed theoretically, in order to an attempt to understand the behavior of T.F in Palestinian conditions.
The impact of engineering solutions are as following: Economical aspects by offers many jobs, new water resource will be available, and the resulted sludge could be used as fertilizers. Environmental aspects by Protect the wildlife, and reduce the pollution of groundwater, in addition to many benefits aspects, finally we recommend to find the source for funding the project.
water is necessary to all living beings. Water is used for a lot of aspects of life, like drinking, washing, industry, irrigation... etc. so It is natural that the use of water will produce wastewater, As a result it Should be considered a safe way to treat it, because it is complex compound has a negative effects in human health, animals and plants, from this point of view construction of wastewater treatment plant (WWTP) the safe way to treat it.
Arraba town does not have infrastructure for WWTP. Apparently, the construction of WWTP is essential and vital for this city which has a considerable population size, In addition the wrong way of disposal of wastewater by collecting it in the cesspits, leading to dangerous affects in groundwater.
It is fundamental to begin the design of WWTP is a determination of design capacity, that includes: 1.selection of deign period 2.estimation of population growth 3.estimation of wastewater flows, and other parts
Objectives
Treatment of waste water coupled with robust management will enhance the public health and environmental.
Objective of this project are to :
1. Predict waste water flows of Arraba.
2. Design of waste water treatment plant for Arraba.
3. Decide on optimal reuse of treated wastewater and sludge.
4. Compare between a model of Trickling filter and theoretical equation of Trickling filter.
Study Area
Arraba is Palestinian town located about 13 km southwest of the city of Jenin, and it has a population around 12,000 people, and it is rising from the sea level about 340 meters, the total Municipal area is 45000 dunums of which an area 2500 dunums is considered to be built area.
Conclusion and Recommendations
- We designed a waste water treatment plant for Arraba.
- The treatment method was Trickling filter .
- There is potential for reuse the treated water.
