The water purification process removes harmful contaminants and unwanted material from a source of water. Contaminants may include hazardous chemical agents, organic and inorganic compounds, metals, mineral deposits, and organisms like parasites, bacteria, and fungi. Water purification aims to remove as much foreign material from the water source as possible, making it suitable for human consumption or use.
Commercial water purification also includes advanced purifying methods such as distillation and deionization. With the distillation process, the contaminated water is turned into vapor, then condensed back into liquid form as the contaminants fall out in the process. Deionization involves removing dissolved concentrations of salt and other material from the water source using specialized equipment.
The United States is known for its standard of living, due in part to the implementation of residential water purification standards that ensure clean drinking water. Numerous industries rely on commercial water purification, such as the medical sector, food and beverage production, pharmaceutical manufacturing, chemical engineering, and many more.
Water Purification Treatment Steps
Most commercial water purification processes follow a four-step method for purifying a water supply:
- Coagulation and flocculation
The first step involves isolating foreign matter in the water and making it more manageable. Dirt particulates pick up a negative charge as they move through the water. Adding a positively charged chemical agent to the water supply begins the purification process by neutralizing the dirt’s negative charge, causing it to coagulate into a larger mass known as “floc.”
Unlike individual dirt particles, the resulting floc is much heavier, so clumped material drops out of the water and settles at the bottom. This step is called “sedimentation,” and it naturally follows flocculation.
Coagulation and flocculation take care of most contaminants, but leftover particles or harmful bacteria such as E. Coli may survive the process. Additional filtration passes the water through a series of filters made out of sand, gravel, and charcoal to remove any remaining debris.
The final decontamination step will eradicate any remaining bacteria missed by the filters. Administering a safe ratio of chlorine will kill remaining organisms and prevent future bacteria growth. No matter how many filters the water passes through, decontamination remains essential because viruses, fungi, and bacteria are microscopic and may slip through.
Deionizer Systems to Purify Water
Deionization provides an extra layer of protection beyond the basic purification process. Through deionization, virtually all contaminants, including dissolved salts, are removed from the water. With many types of deionizing equipment and services on the market that offer a varying range of capabilities, the team at Reynolds Culligan often gets asked: What is the best water purification system for deionizing water?
The answer to that question depends on the scale of the job at hand. Reynolds Culligan offers two different deionization solutions:
- Culligan Premier Series Deionizer System. Our premier line of water purification systems can deliver ultra-purified water on an ongoing basis. Numerous industries contain applications that require “blank water.” Deionized blank water is 100% free from all contaminants. Our premier series offers full control over the deionizing process by allowing full resin tank customization. Users can create a combination of weak and strong base tanks suited to the specific application and choose between a manual and automatic regeneration process for additional control.
- Culligan Portable Exchange Deionizer (PEDI) System. Our line of portable exchange deionizers offers an ideal solution for creating ultra-purified water from remote water sources. Our PEDI systems use a combination of activated carbon and high-quality ion exchange to give you access to clean, purified water in remote locations where mobility is required.
