The technical-study for waste water treatment plant

According to the laboratory analysis and jar test for preceptation type for waste water sample,we notice the following problems:-

1-increasing the cod parameters

2-increasing the mineral parameters as(CUPPER)

3-increasing the turbidity,colour intensity,odour

4- little increasing of oil,grease

So from the above parameter,we suggested the waste treatment steps to be compatable with environmental rules as 44/2000.

Operating steps

Collect water inside the tank assembly first passage of water through the 10-lane gradual rises and traveling at 30 km / h on the degree 55-56 degree for pollutants large and medium-sized sedimentation and water remains inside the tank for 6 hours of deposition before moving to the next step

The pumps lift the water deposited from the top two thirds of the tank to pull part of 50 cubic meter to the chemical treatment tank

The mixer start to work at 400-600 rpm just the waste water inside the tank,so the first chemical (co aggultant=poly aluminum chloride) in liquid state is adding for 10 min at effective ph=4-5,so the ph will deacreasing from 12 to 4.5 to precipitate the large and medium moles directly to the bottom of tank.

So the second chemical ll adding which is (the floculltant=hydrated calcium hydroxide) in liquid phase is adding for 10 min too at effective ph=11,so the ph ll increasing from 4.5 to 11 to precipitate the small moles by collecting firstly at the surface of the water and at definite molecular weight ll precipitated to the bottom of the tank.

So the third chemical ll adding (the clarifiring=inionic polymer) in liquid phase for 10 min to moderate the ph =8.5-9 achieving the clear crystal for water and extra precipitation to the sludge in liquifing pase=35% as small cake

So we stop the mixer to achieving the high level of sedimentration to separating the clear water than the sludge cake

This small cake of sludge is sucking by sucking screw pump to the sludge collecting tank

So the third step ll start from raising the treated water from the chemical treatment tank to the biological tank to make the flotation by air in the presence of chemical active sludge media to breaking all of chemical group which remain without any reaction in the chemical treatment step,so that ll be taking 30 min.

After the end of aeration and flotation,the sludge ll sucking to the sludge collecting tank and the treated water ll raising to the forth step of treating=physical treatment step by movement the water with velocity-25-30 km/hrs through physical chamber one from the top and another time from the bottom,so go to the lamella plate sheet to decreasing velocity to 10-15km/hrs to make high precipitation to the water make our parameters at80-90% in low levels at normal values we need

So the sludge is sucking to the sludge collecting tank

After complete clearfing of water in physical treatment step the water is raising to the final filteration step which consistes of (sand/gravel/active carbon/zeolite) to adapted the ph and temp.,and cod,bod,complete removal of heavy metals and oil,grease,colloidal dissolved solids,odour and colour that ll achieving by bed depth of each media and good specification

to make an extra-filteration,absorption and adsorption at retention time for passing the water inside the medias

The treated water is collecting in the treated water tank ready to go inside the R.O UNIT or direct reused in agriculture or machine cooling

The sludge is ready to treated to sucking and dewatring out side the unit or reused by your team in work shope again

The retention time of treating through the suggested waste water treatment plant for every 10 cubic meter of waste water=3 hrs treated in 4 steps of treatment methods

The treated water ll be=8cubic meter of every 10 cubic meter achieving the total treated water=120cubic meter/150 cubic meter /day

The suggested sludge in 35% liquid phase=2cubic meter/10 cubic meter/hrs=30 cubic meter/150cubic meter /day
