4 Steps In Industrial Water Purification

Filtra-Systems knows what it takes to perform industrial water filtration. However, the full process can seem impenetrable to outside observers. To that end, here’s how a general industrial water purification system works.

Step One: Screening

Source water, either from a natural source or from an industrial one, will typically pass through a screen as it enters industrial filtration systems. This step is important because it keeps large material out of the water system, which can clog or otherwise disrupt the purification processes.

Step Two: Coagulation/Flocculation

The second step is usually the addition of chemicals to the water to be treated. This causes the formation of small yet sticky particles known as floc to begin forming. In turn this floc will attract larger and larger particles. This leads to the now-larger particulate to either sink to the bottom of the floc tank for conveyor removal, or rise to the top in order to be skimmed off.

Step Three: Filtration

Filtration is the critical part of the majority of industrial water purification systems. The water will be pumped through one of many different types of filters, leaving the accumulated floc behind in the filtration media. These filters, which can be made from cloth, crushed black walnut shell (BWS or NSF), sand, or carbon, trap and remove even more particulate as the water passes through them. For example, Filtra-Systems’ patented filtration processes involve the use of a bed of walnut shell media.

Step Four: Disinfection

The now-filtered water is then pumped into a closed tank where disinfectant chemicals such as chlorine are used to destroy any bacteria or other microorganisms that might have survived the filtration process. Other technologies include ultrafiltration (filters with pores of 0.2 micron or less), purification with ultra-violet light (UV), or reverse osmosis (RO).
