DDi
Every factory makes something.
We can also say a factory produces products.
Makes something = Produces products
To produce something, a factory uses water.
The water can be used:
To clean the factory
To clean the products
As part of the product
To cool the product or machinery
To drink or prepare beverages, such as
tea and coffee.
Sanitation
Once water is used, it becomes an effluent. An effluent is used
water that the factory must get rid of.
When used water is cleaned up for re-use, we say it is
treated for recycling.


There are laws that forces factories to clean
up their effluents before it is discharged into
rivers, lakes, the sea or any other water
source. This law is there to protect the
environment.
If the water is part of the product, e.g. in a cool drink
factory, we cannot re-use the water.
If the water is used to clean the factory or the products, it forms a
soapy effluent, that the factory can dispose of or that the factory can
re-use if they can clean it up a bit.
Sometimes they do not need to clean the effluent, if it is not smelly.
They can e.g. re-use cooling water over and over, since it is not
contaminated with anything and gets recycled through pipes all the
time.
