Commercial RO System Buyer's Guide

 In commercial operations, water quality plays a vital role in the quality of production, operations and services in many industries. Commercial reverse osmosis (RO) systems, as a highly efficient water treatment equipment, can remove harmful substances such as impurities, salts, bacteria and viruses from water, providing a high-quality water source for commercial premises. However, with so many brands and models of commercial RO systems on the market, choosing the right system has become a challenge for many commercial users. Below is a detailed overview of the key aspects of choosing a commercial RO system.

Clarify water demand

 Different commercial scenarios have vastly different water quality and quantity requirements. For example, hotels and restaurants need to provide clean and safe drinking water for their guests, and at the same time meet the water needs of kitchen cooking and dishwashing; while industrial manufacturing companies may have extremely high water purity requirements for critical parts of the production process, such as electronic chip manufacturing and pharmaceutical production.

 When determining water demand, it is important to take into account the peak hours of daily water consumption and average water consumption. This can be done by counting the water consumption records over a period of time, or by estimating based on factors such as the size of the commercial premises, customer traffic, number of employees, etc. For example, a hotel with 200 rooms is expected to use about 200 liters of water per day for drinking and washing in each room, and with the addition of water used in public areas, kitchens, etc., the total daily water consumption may reach thousands of liters. Clear water demand is the basis for choosing the right commercial RO system, only an accurate understanding of the required water quality and quantity, in order to select the system to meet the actual demand.

Examining system performance indicators

Desalination rate

 Desalination rate is an important indicator of the RO system's ability to remove salt from water. Generally speaking, the desalination rate of commercial RO system should reach more than 95%, and for some industries with very high requirements on water quality, such as electronics, pharmaceuticals, etc., the desalination rate even needs to reach more than 99%. A high desalination rate ensures that the treated water meets specific industry standards and usage requirements.

Water yield

 Water yield refers to the qualified amount of water that the RO system can produce per unit of time. It is important to select a system with the appropriate water yield based on the water demand identified earlier. If the water production is too small, it cannot meet the peak demand of water in commercial premises, which will lead to water stress; while too large water production will lead to waste of equipment investment and operation cost. At the same time, it is also necessary to pay attention to the changes in water production under different working pressures and water temperatures to ensure that the system can operate stably under various working conditions.

Recovery rate

 Recovery rate refers to the proportion of raw water converted into produced water by RO system. A higher recovery rate means more efficient use of water resources, less wastewater discharge, and lower operating costs. Generally speaking, the recovery rate of commercial RO system is between 50% - 75%, but the specific recovery rate should be reasonably selected according to the raw water quality and system design. If the raw water quality is poor, containing a large number of impurities and salts, too high a recovery rate may lead to clogging of the membrane element, affecting the service life and performance of the system.

Focus on the quality of the membrane element

 The membrane element is the core component of the RO system, and its quality directly affects the performance and service life of the system. High-quality membrane elements should have good desalination performance, high water yield and strong anti-pollution ability.

 When choosing a membrane element, it is important to understand its brand and model. Membrane elements of well-known brands usually undergo strict quality testing and market verification, and their performance is more stable and reliable. At the same time, according to the raw water quality and use requirements to choose the appropriate membrane model. If the raw water has a high content of organic matter, should choose a strong resistance to organic contamination ability of the membrane element; if the purity of the water requirements are very high, should choose a higher rate of desalination of the membrane element.

 In addition, but also focus on the service life of the membrane element and replacement costs. Generally speaking, the service life of the membrane element in 2 - 5 years, but the actual service life will be affected by the raw water quality, operating conditions and other factors. When selecting a system, it is important to understand the replacement cycle and price of the membrane element in order to rationalize the cost in the subsequent operation process.

Evaluate system stability and reliability

 Commercial RO systems usually require continuous operation for a long period of time, so the stability and reliability of the system is crucial. Choose products made by manufacturers with good reputation and rich experience, who have more specialized skills and experience in system design, manufacturing and installation to ensure the quality and performance of the system.

 Understand the system's fault alarm and protection features. A perfect commercial RO system should have a variety of fault alarms and protection features, such as high pressure protection, low pressure protection, overcurrent protection, water leakage alarms. When the system is abnormal
