Process water is a general term, and since each system can vary based on the water quality and the environmental regulations for its reuse, there is no universal treatment process. Nevertheless, basic requirements must be met when dealing with produced water. It is important for companies to understand these factors so that can be maximized while containing costs and complying with regulations.
Water, even if it’s occurring in nature, consists of a lot of minerals which can harm industrial pipes, boilers, etc. by causing corrosion, scale building, spotting on finished surfaces, precipitation in chemical products and other related problems. Thus the following water treatment techniques are used to maintain a long life for these costly equipment and produce ultra-pure water with higher specifications.
Demineralization & Reverse Osmosis Techniques.
Each Process consists of a set of stages each with a certain requirements and benefits according to the application
- Preliminary treatment or pretreatment is any physical, chemical or mechanical process used on water before it undergoes the main treatment process. During preliminary treatment :screens may be used to remove rocks, sticks, leaves and other debris; chemicals may be added to control the growth of algae; and also a pre-sedimentation stage can settle out sand, grit and gravel from raw water.
- RO stage As illustrated in the figure we tend to apply a very high pressure is applied to the concentrated solution, the water molecules are forced through the semi-permeable membrane and the in which bacteria, heavy metals, salt, bad mineral substances and other dissolved matter and chemical drugs are removed from water to be collected in tanks for use .
