Hi MartinLe,
After having achieved the discharge norms, the effluent from the wastewater treatment plant can be considered fit for secondary use. After treatment the potential harm causing elements that remain in treated water are pathogens. Chlorination helps in making water pathogen free thus...
Hi all,
Can anybody help out about this:
What are the Wet Utility (Storm Water Drainage, Water Distribution and Wastewater Collection Network) Design Guidelines that are followed in Norway?

Having the crown of the force main below the invert of the outgoing sewer shall have the following issues:
1. Sewage could turn turn septic if it stands within the main/manhole idle (i.e. which will happen during the lean hours). Moreover it shall also start depositing the particulate matter...
The details are as follows:
1. Service (Fluid) : Untreated Sewage (Wastewater)
2. Size of the pipe : 180 NB
3. MOC : HDPE
4. Flow / Velocity : 12 l/s / 0.7 metres per second
4. Length : 2000 meters
5. End Connection : Open to Atmosphere
6. Profile: Indicative (See attached)
I hope I have...
I have worked with Bentley's WaterGEMS for the last 5 years and in my experience I have found the software easy to use moreover the software is well equipped with everything that is needed out there in the job. However I cannot offer you the difference between the two, because I have not used...
Thank You LittleInch.
The fluid velocity within the underwater conduit is around 0.7m/s.
The main issues are:
1. The incoming flow at the particular pump station is low.
2. We have very less chance of reducing the diameter.
In this case is there a way out of the removing the air within the...
I am in need of urgent help.
Can anyone please tell me how is the air removed from a offshore pipeline?
The air that gets accumulated within a pipe pumping liquid and since the pipe being below over the sea bed how do we remove the accumulated air from it?
For instance if the pipe is above...
Hi
I have modeled a FCV in EPANET to control the flow at a desired value but I am receiving a head loss of 18 meters after FCV.
Can anyone help me in reducing this pressure drop/ head loss across the FCV? I am working in EPANET.
Thanks in advance.

Usually the Material Of Construction (MOC) for used for Sluice Gates in wastewater treatment plant are as follows:
1. Untreated Wastewater - SS 316 (MOC)
2. Primary Clarified Wastewater - Cast Iron (MOC)
3. Treated Wastewater - Cast Iron (MOC)
4. Sludge Streams - SS 316 (MOC)
In addition to...
Over a period of time the sludge/settle-able matter shall settle and solidify due to surcharge. This will result in septic conditions and shall also reduce the pipe opening which will result in choking of connecting sewer. Though all other connections are high enough than the main line but if...
Check whether the source water contains nutrients (Nitrogen & Phosphorus). Presence of excess nutrients with sunlight causes algal growth.

Yes, indeed as said above refer the Code because every pipe manufacturer has to adhere to the prescribed codes. Moreover the Code clearly explains the topic, needed values and everything in regard. The Code to be selected depends upon the region wherein you are working. If there are no region...
I have to model a water pumping main from point A to Point B with Pump C and Pump D operating in parallel. Can anybody help me by confirming that we could model model parallel pumps in EPANET?
