How about this kind T1?

The given diagram gives data on the removal of salts and impurities from sea water to make it drinkable. What stands out from the graph is that the main stage of the process is explained more in detail.
Firstly, saltwater from the sea is flowed to the initial stage called pretreatment filter. In this stage divided from saltwater filter backwash is re-directed to the sea. Afterwards, water is forced to pass through membrane at high pressure where in turn seawater concentrate is pumped simultaneously with filter backwash to the sea.
Post treatment, in which water is treated with lime, chlorine and fluoride, is the next stage after which water is amassed in storage. Then water reaches its final stage-integrated water supply system.
As about the membrane, whose holes are drilled so accurately that only water molecules can pass through, it returns molecules of impurities and salt to the pipe back to the intake source.

Hello!

Generally a good report. You have included the required information. There are some mistakes. For example, the second sentences can be removed/changed. It is not really relevant as a key point. Grammar and vocabulary are both good and any mistakes do not interfere with meaning.

All the best,
David

If i remove the second sentence there will be 120 words in total.

Hello!

Yes, so you'd need to find ways to add extra words to your report, for example by adding a summary of the main parts of the diagram. It can be done!

All the best,
