Pure water purification plant

Types of Pure Water Purification Plants

A pure water purification plant exists to provide safe drinking water for individuals and communities. However, within these plants are distinct systems that make them functional.

• Reverse Osmosis (RO) Systems

  Osmosis is the movement of solvent molecules through a semipermeable membrane from a low solute concentration to a higher solute concentration. Reverse osmosis is the opposite of osmosis. It is a water treatment process that removes impurities from water by pushing it through a fine membrane with the help of pressure. An RO system eliminates contaminants, such as salts, viruses, bacteria, and chemicals, from water. What makes reverse osmosis special in functioning as a water purification system is that it removes these unwanted substances while leaving only pure H2O behind.

• Ultraviolet (UV) Water Purification Plants

  UV water purification makes use of UV light to destroy bacteria and other pathogens in water. UV water purifiers come with a lamp placed inside a quartz tube, which radiates water with short wavelength light. The light rays disrupt the DNA structure of microorganisms like bacteria, viruses, and protozoa, preventing them from reproducing and causing disease. One interesting thing about UV water purification is that it doesn't alter the mineral content of water. For this reason, a UV system can be used as an addition to an RO water purification system.

• Ultrafiltration Water Filtration Plants

  Ultrafiltration is somewhat similar to reverse osmosis. However, it is a membrane filtration process with larger pore sizes than reverse osmosis. Ultrafiltration membranes remove suspended solids, bacteria, and viruses from water. It does this by allowing water and other small molecules to pass through the membrane while retaining larger molecules like pollutants and microbes. Ultrafiltration doesn't require high pressure like reverse osmosis. For this reason, it is often used to treat surface and groundwater containing high levels of dissolved solids.

Specifications & Maintenance

The specifications of the commercial pure water plants vary depending on the design, capacity, and the machines used.

• Capacity: The ability of the plant to produce pure water is directly linked to its size, machinery, and setup. Small-scale facilities can generate 500 liters of pure water every day. Meanwhile, big industrial plants have the capacity to produce tens of thousands of liters daily.
• Treatment Steps: A lot of steps are necessary to purify water, including pre-filtration, disinfection, reverse osmosis, post-filtration, UV sterilization, bottling, and labeling. Different types of filters, chemicals, and equipment are used for each step.
• Equipment: The type and size of the water purification plant will decide what sort of equipment it will need. This could include water tanks, filters, pumps, reverse osmosis membranes, UV lamps, and more. The quality and capacity of each piece of equipment will need to match the demands of the plant.
• Power Use: Plants that purify water use different amounts of power because of the motors, pumps, and other electric equipment they have.

Maintenance is critical to ensure the on-site water purification plant's consistent performance, longevity, and product safety. A few of the main tasks are as follows:

• Routine Checks: Daily checkups should be planned. During these routine checks, operators should look for leaks, strange noises, or obstructions in the equipment's work. They should also record the system's operating status, including water production volume, pressure, water quality testing results, etc., and keep the records for future reference.
• Parts Maintenance: Operators should clean and replace filters for pure water plants regularly. They should choose the proper cleaning solution and method, ensuring that all components are thoroughly cleaned.
• Lubrication and Maintenance: Keeping the moving parts of water purification systems well-lubricated is essential. The pumps, valves, bearings, and other parts are included. Operators should use the proper lubricants to minimize wear and tear and ensure smooth operation.
