Water Treatment is a broad term that is used to describe the processes that are used to make water more acceptable for the end use, whether it be for industrial, commercial, medical, or personal use.  The purpose of water treatment is to remove contaminants of the water, or to reduce the concentration of certain contaminants or elements in the water.  The purpose of this processing is to make the water more desirable and acceptable for end use. 
Water treatment may be used to make water suitable for use in industrial applications, such as cleaning or cooling equipment, Open Loop HVAC Systems, and more.  It may also be used to make contaminated water suitable for personal use, such as shower water, doing laundry, washing dishes, or even drinking water.  All water used in hospitals and for medical application must be purified in order to avoid contamination or transmission of disease or other undesirable elements.  No matter what the end use of the water is, water treatment is usually a necessary and vital stage in preparing it for use. 
There are many different types of water treatment, and there are a variety of factors that will determine the type of water treatment necessary.  These factors include, but are not limited to:

  • The condition of the water to be treated

  • The amount of contaminants present in the water

  • The type of contaminants present in the water

  • The purpose of the water after treatment

The condition of the water to be treated:
            While all water has the potential to be clean, potable water, some water requires more processing than other water.  For example, wastewater requires much more treatment that both grey water and rainwater.  Water that has a high amount and a variety of suspended solids requires a greater amount treatment than water with light sediment.  The condition of the water will determine the type of treatment that will be used, and it will also determine the source of water to be used.  While all water has the potential and ability to be cleaned and treated, it is best to use a water source that will require the least amount of treatment to make it suitable for it’s end purpose. 


The amount of contaminants present in the water
            When creating a water treatment system, different treatment technologies can be used based on the type of water to be treated.  One factor in determining the type of treatment technology to be used is the amount of contaminants present in the water.  In the case of water that has a low concentration of contaminants, and where the contaminants are very small, it may be more cost effective to use a type of membrane filtration without pre-treatment.  But, when the water to be treated has a high amount of suspended solids and contains many larger particles and contaminants, these would likely clog a membrane filtration system quickly, which will require more frequent replacement of the filters, which will create higher operating costs.  One possible solution in this situation might be to install a pre-treatment filter that will remove the large contaminants and can be cleaned and re-used.  This would leave the membrane filtration system to remove only the smaller particles, allowing it to last longer before it needs to be replaced.  While this specific type of water treatment may not be the right fit for all applications, Purewater has the experience and the knowledge to create a custom water filtration system that will be cost-effective, efficient, and will meet your specific needs. 


The type of contaminants present in the water
The specific type of contaminants in the water to be treated is an important factor to consider when creating a water treatment system.  For example, a reverse osmosis or membrane filtration system will remove suspended solids, but may not do a sufficient job of disinfecting bacteria in the water.  For water with a high bacteria content, it may be necessary to add ultraviolet (UV) disinfection before the water goes through a reverse osmosis filter. 


The purpose of the water after treatment
Another important factor to consider when creating a custom water treatment and filtration system is the proposed end use of the water.  If a client is looking for a system to treat water that will be used for washing clothes, shower water, or other similar uses, it is important that this water go through certain treatments that make it safe for human use.  While the water is not intended for human consumption, it may need to meet a certain standard of cleanliness and safety.  On the other hand, if the water is intended to cool industrial equipment or it is being used in an open loop HVAC system, the focus of the water treatment system will be in removing suspended solids that could damage the equipment or create mineral buildup.
