I have seen some water treatment plants located many kilometres away from the catchment areas, I have also seen others located within the catchment areas. Some treatment plants use chemicals for purification, others don't. what determines this.
many factors can determine the site of the WTP .
1- the cost
2- the source of water and the best location along the river. if ground water, best aquifer can determine the site of WTP.
3- other environmental and geographical conditions also play a vital role.
the degree of contamination of the water determines the type of treatment. and also, the cost.
1. It should be along the flow (level).
2. Near to an industry
3. At a distance from the community
4. Accessible
5. Large enough with the possibility of extension in future.
6. Sludge treatment and disposal facility.
Type of treatment plant
1. Primary (Physical)
2. Secondary (Biological)
3. Tertiary (Chemical)
These various options purely dependent on physical and chemical characteristics. Generally a good treatment plant consist of primary and secondary treatment facilities.
Area of a wastewater treatment purely depend on the flow rate (Volume/second or other units) the effluent drain and retention time.
Thank you so much for your feedback. I should have mentioned that I am looking at the Drinking/Domestic Water Treatment/purification Plant. Any resources towards this end would be very helpful.
Source of water such as river/bore wells/ catchment/ water shed should be closer to water quality treatment plant. First raw water is treated for water supply, and than treatment to make water for drinking purpose. This require water purification laboratory. After passing through water quality control ,make water to supply for drinking/domestic purposes.
This is a good question. The answers given by my colleagues Rami and Dr Virendrakumar are quite satisfactory.
Most important determinant is the source - the water supply should be obtained from most feasible source. Feasible means adequate protection by natural means- dilution, storage, sedimentation, sunlight, aeration which tend to have natural purification of in surface waters and in case of ground waters the natural purification by infiltration through soil and percolation should be available or adequate protection by treatment is any combination of the processes of coagulation,sedimentation sorption, filtration disinfection or other processes to produce water to meet the requirements of standard.
If the source is not adequately protected, the supply shall be adequately protected by treatment. frequent sanitary surveys should be made to identify health hazards.
Further the adequate capacity to meet the peak demands without development of low pressure should exist. Then the water treatment plant near such source should be located.
It has to be further seen that the point to treatment connection to the consumer service piping free flow should be available.
The selection of treatment train depends upon the quality and variability of the raw water source and the treatment objectives. A thorough survey of the quality and the quantity of all possible sources is the first and most important task for designing water supply processes.
Basically, the cost, proximity to the water source and the type of contaminants (Physical, chemical, biochemical or microbial) play dominant role in determining site and type of WTP.
Yes Short and sweet Dr Nyakno. I also support very much to the answer given by Dr K N Sheth
The following should be considered:
-Source of water should be closer to water quality treatment plant.
-Type of source
-The site should be accessible
-The site characteristics i.e. ground characteristics that will dictate construction of treatment facilities
-The cost
-Environmental aspects,-Sludge treatment
-The Method of supply- Gravity or pumping.
Thank you good people for your responses. I now have a better understanding. I really appreciate the comments and answers.
Dear wwt plant researchrs. Its indeed v educative. Adding to Dr Naffees Mohd. notings wil include a Pre Process Equalising chamber of apt size and inflow amd outflow duly arranged to takr care of physical particles..
At tthe end of process to slot in a phyto remedial pit for curing & polishing process if the effluent is for recycycling ie re use for irrigation etc.. The actual benfit of a wwt plant is proven when it is re used in communities.. w wshs ..
Very important is the location near to the waste water receiver, location in relation to the sewerage system, the quality of the ground, distance from buildings, distance from protected natural areas. The treatment technology depends on the source and composition of the waste water
Dear colleague
1- access to energy. 2- access to espesialist in wwt. 3- develpe for future
4- chemicals requrment. 5- odor problems 6- sludge removal
7- access to clean water 8- solid waste disposal 9- access to road, railroad, etc. 10- far from bulding or city 11- quality of tratment
12- reuse and recovery 13- lacal and international standard
14- the cost 15- operetion and maintenance of wwt
16- acess to new technology 17- persoal (staff) requirment
18- access to a big ground and usefull it. 19- suitable slope of the site.
20- attention to wind and speed wind and other environmemt problems
sorry, my recommends proposed suitable for wastewater treatment plant not water treatment plant.
1. At a distance from the place which people live
2. Large enough at the future.
3. the source of water and the best location at deep point far from the soil
4. study the degree of contamination at the point
and the results of degree of contamination is responsible for the type of treatment which used
