Containerized reverse osmosis

Types of Containerized Reverse Osmosis

The containerized reverse osmosis system is made up of various containerized RO water purifiers and a container. There are many types available in the following table:

• Flexible container

  A flexible container is a sizable, strong, and waterproof bag. It's the most practical and lightweight option.

• ISO Container

  An ISO container is built to steadfastly follow international shipping and trading norms, as its name implies. Because it's as massive as a whole shipping box, moving it is quite easy. This type of containerized reverse osmosis system has an extremely high level of robustness and is able to stand up to any weather or sea conditions. The characteristics of ISO containers make them ideal for sea or road transportation over long distances.

• Skid Container

  A skid container is mounted on a platform (known as a skid). Normally, it's designed to be brief and light, weighing about 1,000 kg. A container like this would be rigid enough to endure air freight or overland trucking operations. This setup would allow it to easily cope with any normal truck or airplane transport journey.

• Trailer Container

  A trailer container is mounted on a road trailer. The size is similar to a skid container. But the robustness of a trailer container is better than that of a skid container. It can be used to safely and steadily transport heavy goods.

• Walk-in Container

  A walk-in container allows personnel to enter and work within the system. Containerized reverse osmosis plants are often housed in a walk-in container for ease of maintenance and service.

Specifications and maintenance of containerized reverse osmoses

Specifications

• Water capacity: Containerized RO systems can handle different amounts of water, usually measured in liters or gallons per hour. The size of the system will determine how much water it can process.

Maintenance

Regular maintenance is required to ensure optimal performance as well as to extend the life of the containerized reverse osmosis system.

• Regular inspection: Users need to check components such as membranes, pumps, valves, and pressure gauges regularly. In this way, the early signs of damage, leaks, or malfunctions can be detected and addressed promptly.
• Pretreatment maintenance: Containerized reverse osmosis systems usually include pretreatment units such as multimedia filters or antiscalants. The efficiency of these pretreatment devices has a direct impact on the performance of the entire system. Therefore, regular maintenance of the pretreatment unit is necessary so that it can function properly.
• Cleaning of membranes: The membranes are at the very heart of containerized reverse osmosis systems. They are subject to fouling and clogging over time, which affects their filtration efficiency. Regular cleaning of the membranes is necessary to ensure stable and efficient operation. Appropriate cleaning agents and techniques should be used according to the type and fouling of the membranes.
• Replacement of components: Apart from the RO membranes, other components such as filters, pressure gauges, and valves also require periodic replacement and maintenance. Monitor the condition of these components and replace them as needed to ensure system reliability and accuracy.
• Record keeping: During the maintenance process, it is necessary to keep maintenance records. The records should include maintenance dates, details of maintenance and replacement, inspection results, etc. This helps to track system maintenance history and provides reference for future troubleshooting and optimization.

How to choose containerized reverse osmosis

• Water analysis:

  Perform a detailed analysis of the water business stakeholders intend to treat. Understand the volume, flow rate, and pressure requirements of the business applications. Consider the available space for the installation of a containerized RO system. Most systems are designed to be portable and fit into a standard shipping container or one with a custom-built frame.

• Flexibility and scalability:

  A containerized reverse osmosis system offers flexibility and scalability by providing the option to expand or contract the system as the business needs change. If the water treatment capacity required by the business is uncertain, it may be beneficial to invest in a containerized RO system that has the ability to be scaled up in the future.

• Modularization:

  In containerized reverse osmosis systems, the individual components, such as the pre-treatment unit, RO unit, post-treatment unit, storage tank, and pump, are typically housed in separate modules or containers. This modularization allows for greater flexibility and adaptability in water treatment solutions. It also facilitates easier maintenance and repair, as specific modules can be serviced or replaced independently if needed.

• Localization and unpacking:

  In some cases, it may be necessary to relocate the containerized RO system to a different operational site or unpack it so that the individual containers can be locally installed. In such situations, the localization and unpacking of the system is likely to involve more deployment and installation effort than returning the unit to a supply chain.

• Cost:

  Cost is the most crucial factor in determining business success or failure. Economies of containerization reduce supply chain costs through more efficient shipping and handling, but the cost of pre-treatment and post-treatment technology integrated with the RO may be high.
