Surface Water Treatment

Product Description
Surface water treatment process

The first step within any surface water treatment plant is to initiate coagulation which is the combination of coagulants such as polymers, chloride and sulfate in the water. This mixation targets the unwanted substances by making them join together and create larger substances called flocs. 
Once the process of coagulation is done, then water enters the next stage called flocculation. In this stage, the created flocs are forced to combine with each other and entangle other suspended solids, which creates an even larger and heavier substances that are targeted for removal in the next stage.

The next stage in surface water treatment is known as sedimentation, which slowly takes the flocculated water through a tank or basin while keeping the large flocs at the bottom of the system, where they will eventually be eradicated.

The sedimentation stage is important since it eliminates suspended solids from the water through the use of filters made of coal, sand, and other particles. The treatment in this stage also produces perfectly clean water due to the sharp decrease in turbidity.
Surface water treatment also incorporates carbon which eliminates certain chemical substances in a process called carbon absorption. To prevent unwanted contaminants being stuck in the small passageways between grains of sand, this process forces these contaminants to be attached to the surface of carbon and are effectively eliminated.

The final stage of surface water treatment is called the disinfection stage which includes the addition of chlorine, ozone water treatment and other disinfectants to remove microbiological organisms such as bacteria, viruses, parasites, etc. Throughout the surface water treatment process, a great deal of time is spent adding sufficient disinfectant to maintain a residual amount in the water to effectively remove all pathogens in the passageways.

Pure Aqua provides you with experts to ensure that the most quality surface water treatment and management is implemented and maintained. By providing a custom water purification process to manage your plants, there will be a 100% guarantee of safe and dependable water supply, and minimal operational cost to your plant.


Surface water are sources of water found on the earth’s surface such as creeks, rivers, streams, lakes, snow, ocean water, land consisting of marshes, etc. Surface water is generally lacking of mineral content, and is often referred to as “soft water.” This water is highly vulnerable to various pollutants including industrial wastes, pesticides, animal wastes, algae, and many other organic substances. The vulnerability of this type of water to contamination is so substantive that even surface water sources from seemingly immaculate mountain streams can be polluted with animal wastes, or other decay.

Surface water treatment requires a great deal of time and the incorporation of advanced technology in order to make surface water consumable. Surface water must go through a plethora of processes before it is made available to the public to consume.



Ultrafiltration is considered the most effective water treatment solution in regards to the production of purified drinking water from surface water. Our ultrafiltration systems consists of hollow fiber membranes (out-in technology) to filter surface water from turbidity, TSS suspended solids, ultramicroscopic particles, and biological microorganisms such as viruses, germs, bacteria, larvae, and protozoa.

UV water treatment systems

Another solution to treat surface water is by ultraviolet disinfection. UV water treatment systems incorporate special chambers for purifying surface water which are designed to deliver a dosage of UV light at certain flow rates. UV systems operate to its highest efficiency when the water is clear and free of particles. For this reason, surface water will need to go through some type of pretreatment system such as ultrafiltration or media filtration to ensure optimal UV treatment. UV water treatment systems entail less maintenance requirements and do not necessitate the addition of chemicals. UV systems also provide the usage of warning alarms to alert the user of equipment faults.
