Design of aeration tank is already uploaded in the channel.. please go through the channel..and I will upload the design of equalization and tube settler soon..
Sir, many thanks for the video. I want to learn about design of Waste Water Treatment Plant i.e mathmatical calculation about flow, volume of respective tanks etc. Kindly guide me how to obtain this knowledge.
Sir, This calculation is limited for manual bar screen or we can use this for mechanical rake type bar screen. Also, please guide how to decide angle of inclination.
Hand cleaned racks are set usually at an angle of 45 to 60 degrees to the horizontal to increase the effective cleaning surface and facilitate the raking operations. OR you can use formula of head loss(in terms of angle of inclination) to calculate angle of inclination.
Dear Sir, Please could you explain me or design for Bar Space 5mm, Width of channel 500mm, Depth of Channel 1000mm Thank you and look-forward to hear from you, Regards, Vijay
Dear friend, We can design the screening unit depending upon the flow rate. Then, assuming the velocity of flow(0.6-1.2 m/s) through the screen and design flow rate, we can calculate the cross sectional area of screen( area through which sewage is flowing,it doesn't include diameter of bars). Then by assuming depth, calculate width( width through which water is flowing,it doesn't include diameter of bars) and then assume clear spacing and calculate the bars from the width of channel. Then, calculate total width of channel i.e. width + diameter of bar*number of bars. Also calculate length of screen by assuming angle of inclination (45-60). At last take check for head loss. In your questions, you have given bar space, width, and depth of channel. If all these value are given then why we are going for designing because these value depends on flow rate and velocity.. we can not assume all these value..we can assume only one dimension and rest of the dimensions we have to find. For this, refer this video or you can find the design guidelines in CPHEEO manual.
the last w2 is what at Q1=Q2?
Superb work..great guide for learners
Thanks 😊 keep watching 👍
Sir,
I have one dout, what is the value of 0.0729 in head loss calculation and why it's applying in head loss calculation
Sir,
Capital v is maximum through velocity of screen and the small v is minimum approach velocity of the screen.
Sir please make a vedio on design of equalization tank, aeration tank, tube settler
Design of aeration tank is already uploaded in the channel.. please go through the channel..and I will upload the design of equalization and tube settler soon..
Net width of the screen's unit is wrong , the unit of meter not for meter square.
How is clear spacing width equal to 5 when calculating approach velocity?
Clear spacing is assumed...
Isn't clear spacing is equal to 50mm?
Clear spacing depends on type of screen.
As per CPHEEO manual
For fine screen = 5 mm
For medium screen = 12 mm
For Course screen = 25 mm
Hiiii sir muje water treatment plant ki design karni hai but error aa rhi hai sir please help me sir 🙏🙏🙏🙏🙏
How can I contact you, I would like to take private class for design calculation of sewage treatment plant.
Sir, many thanks for the video. I want to learn about design of Waste Water Treatment Plant i.e mathmatical calculation about flow, volume of respective tanks etc. Kindly guide me how to obtain this knowledge.
Design of all treatment units are available on my channel.
Apki sceen bar design ka numericals atay hain mujhay samjha dain gi i have exam on Tuesday?
Can i solve to solid on same calculations?
Sir,
This calculation is limited for manual bar screen or we can use this for mechanical rake type bar screen.
Also, please guide how to decide angle of inclination.
Design guidelines are same but for ready to installed screening unit design criteria are generally as per the chosen manufacturer’s design standards.
Hand cleaned racks are set usually at an angle of 45 to 60 degrees to the horizontal to increase the
effective cleaning surface and facilitate the raking operations.
OR you can use formula of head loss(in terms of angle of inclination) to calculate angle of inclination.
Please provide a design for the Fine screen too
I will upload it soon 👍
Sir agr hami Peak demand = 258 M per day hoto
Flow rate increases ho jata h? To kesi design kr sakti h
Please guide how much % is considered for headloss calculation. What standard is considered for headloss.
Usually accepted practice is to provide loss of head of 0.15 m but the maximum loss with clogged
hand cleaned screen should not exceed 0.3 m.
👍👍
Why can't we apply Pythagoras theorem to determine inclined length
0.87 m (8:17)
Yes..it's meter not meter square 👍
👍
Thanks for watching..👍

Thanks for watching..
Bro the units of width is meters
Yes..it was mentioned by mistake..unit of L/W/D is Meter
Tq bro
Thanks for watching..👍
