Types of DI Water Systems

Deionized water (DI Water System) refers to water that has had all its ions removed. An essential part of creating deionized water is a deionization machine. Several kinds of machines make deionized water.

• Small Capacity Portable DI Water System

  A portable deionized water system produces small quantities of deionized water on demand, typically ranging from a few liters to around 20 liters per hour. It does this using mixed-bed resin canisters that combine both cation and anion exchange resins into a single bed. This setup maximizes the removal of ionic impurities, resulting in water with minimal conductivity. Portable deionized water systems are commonly used in applications like laboratory work, automotive, and electronics. The key advantage of portable systems is their ability to produce deionized water on-site, reducing the need for costly and time-consuming water delivery services.

• N Autodiionization Water System

  An Automatic DI Water System is distinguished from manual systems by its autonomous operation and efficient continuous water supply production. As the name implies, it operates without any manual intervention. The system can produce deionized water continuously and efficiently without stopping or shutting down, thanks to automatic controls. This automatic water production is made possible using mixed-bed resin tanks with automatic refill controls, inline conductivity monitors, and automatic controls. The tank fills and empties as the water flows through it based on continuous inline conductivity monitoring. The system runs without operator intervention thanks to automatic replenishing controls that are based on the water's conductivity. The accurate control of ion exchange resins in this way guarantees a steady supply of deionized water and high resin efficiency.

• Large Capacity Automatic DI Water System

  A Large Capacity Automatic DI Water System shows how well they can deliver deionized water for industrial and commercial purposes. These sophisticated systems use a mixed-bed of cation and anion exchange resins to provide large quantities of deionized water quickly and reliably. Due to their automated resin replenishing mechanism, which decreases downtime by guaranteeing that the resin beds are constantly active, the systems are extremely productive. The resin beds can easily be recharged thanks to skid-mounted big capacity automated DI water systems, which are built for adaptability and convenience. In addition, the systems have inline conductivity monitoring, which ensures that the water output continuously meets the necessary purity levels. Large capacity automatic DI water systems provide dependable, cost-effective solutions for businesses, laboratories, and other organizations that rely on a consistent supply of deionized water.

• N Mixed Bed DI Water System

  Both cation and anion exchange resins are included in a unique arrangement known as a mixed bed in mixed bed deionized (DI) water systems. To remove both positively and negatively charged ions from the water, the resins interact with the water in a single container. This setup improves ion-exchange efficiency and produces a higher quality of deionized water with low conductivity. Because of their compact size and constant resin usage, mixed-bed DI water systems are useful for a range of uses, including laboratories, power plants, semiconductor manufacturing, and boiler feed water treatment.

• N Reverse Osmosis + DI Water System

  Combination Reverse Osmosis + DI Water Systems use deionization following reverse osmosis (RO) water filtration as a final polishing step. They provide the highest level of water purity possible using double filtration. The removal of dissolved solids and contaminants from the water is accomplished through ion exchange in the deionization process following the reverse osmosis filtration, which eliminates inorganic ions and a majority of contaminants. By combining the two technologies, these systems provide water of unparalleled purity ideal for critical applications such as laboratory research, medical facilities, and industrial manufacturing processes.

Specification and maintenance of DI water system

Specification

The following specifications are crucial when choosing the DI water system.

• Sizes and Flow: The deionized water system components available for commercial use range from 100 liters (26 gallons) to 500 liters (132 gallons) in tank size. The flow rates for the system range from 300 to 500 gallons per hour (GPH).
• Filtration: Different types of filters are used in the deionized water system, including particulate filters, carbon filters, and reverse osmosis membranes. Each employs a distinct method to eliminate impurities and enhance water quality.
• Purity: The conductivity of the deionized water system indicates the extent of ion removal. A lower conductivity signifies higher purity, often measured in microsiemens (µS). High-quality systems can produce water with a conductivity as low as 0.055 µS, which corresponds to resistivity over 18.2 megohm-cm.
• Pumping systems: Please remember that the deionized water system operates at high and low pressures. High-pressure pumping systems work to force the water through the reverse osmosis membranes. They use centrifugal pumps or diaphragm pumps with a permanent magnet motor. Low-pressure systems use gravity and have float valves or a solenoid to create the flow.
• Separators and Strainers: In a deionized water system, strainers are used to prevent any contaminants from moving into the ion-exchange resin tank. The separator is a device to allow a service technician to remove only a part of the water from the tank.

Maintenance

A deionized water system needs continuous maintenance to produce the required high-quality water. The following components will require a maintenance schedule:

• Pure Water Systems: In a deionized water system, the two primary maintenance tasks include the replacement of filters following a prescribed schedule and periodic sanitization, including disinfecting the storage tank and transferring lines.
• Water Softener: Hard water with calcium and magnesium ions can damage the deionized water resin. Water softeners utilize sodium to reduce the hardness level and allow the water to pass through the deionized water system. Cleaning salts help regenerate themselves, including sodium chloride and potassium chloride. They are often referred to as brine solutions.
• Carbon Filter: The carbon filter in a deionized water system absorbs chlorine before it damages the reverse osmosis membranes. An upstream sediment filter removes large particles. Carbon filters eventually become saturated and must be replaced.
• Reverse Osmosis (RO) Membranes: Impurities removed from water collect on the RO membranes. Regular flushing cleans the membranes and removes the impurities that have recently built up. Sanitizing the deionized system also sanitizes the RO membranes. If there are high turbidity or total dissolved solids in the incoming water, pre-treatment before reverse osmosis is essential.
• UV Lamp: In some deionized water systems, a UV lamp kills bacteria or other microorganisms. Maintaining the lamp requires periodic cleaning to remove mineral buildup.
• Flow Regulator: A flow regulator maintains the water flow through the deionized system. It is essential to check it periodically to ensure it is functioning properly and to replace it if it is damaged.
