Hi, I use a software called SIMBA, you might also want to check it. It looks like they have some license for study purpose or demo which might be sufficient for some cases.

Visio P&ID is to draw documents.
'Activated sludge expert' appears to be discontinued.
I think your best bet is the *non-free* software from EnviroSim Associates, PetWin.
Failing that you can try using the municipal wastewater treatment plant software, but be aware that they are set up for a different system - no sulphides, little handling of inhibition, ...

Hi Atiq
Trust you are keeping well.
I would suggest you VisioP&ID Process Designer software.
Below is the free trial version link

Hi Atiq,
As you know there are many processes to treat those effluents. If you want to use activated sludge as a process of treatment you can use a free software named "activated sludge expert".
Published by OTMAN AIT IHIA, Engineer, Researcher at Mohammadia School of Engineers
as Gary says, you need to know the composition of the wastewater first, and then you should pay attention to the available pretreatment processes. To mention API or Tilted Plate separators with coalescing material, followed by a DAF with emulsion breaker dosing should remove the bulk of your organic load and reduce the needed volume for the biological treatment and oxygenation capacity. Note that you may need to dose nutrients N&P for a balanced activated sludge process.

the Activated Sludge Expert from the German DWA (former ATV) is typically designed for domestic or household sewage , so not really suited for refinery wastewater. And it's not free.

Hello Atiq, there are a number of options or combinations of processes to treat refinery wastewater. Typically one should understand inflow loading by characterisation, só sampling and testing of content as well as quantification of flow volume per day
once this is determined the target treated effluent quality should be determined, for example discharge to sea or environment, recycling on site or tertiary re-use
once this is available a process configuration can be established and modelled and relevant software can be identified
biological activated sludge or any attached growth process basic design modelling can be established on empirical design criteria in the form of a spreadsheet

I have also collected target effluent quality parameters except fresh inffluent analysis. slugde remove from the steam and discharge into the sea

I am waiting fresh waste water analysis. however, five streams of waste water available 1- desalination plant rejection / brine water , 2- spent caustic from merox unit , penex and CCR , 3- Primary cooling water from process area , 4- Oil water effiuent comes from various streams like process area, utilities and common facilities. 5- sour stripping water from CDU De-salter / Brine

All the biochemical components of the urine plus the methanation released by the decomposition of organic matter generate gases which rise from the bottom of the tanks. Just stir the effluent to kill this process
There is no anaerobic process in a fully Aerobic tank containing H2o water (one hydrogen molecule for TWO MOLECULES
OXYGEN)
It is impossible that a state without oxygen can be created in a completely Aerobic environment which is more in motion.
