I. Avoid the Misconception of Choosing the Largest Flow Rate
The industry mainstream suggests that food factories should choose the largest possible flow rate reverse osmosis equipment for greater stability. I believe this view is out of touch with actual production. Last year, a pastry processing customer blindly purchased a 10-ton/hour high-flow-rate system, but the actual peak water consumption was only 6 tons/hour. The equipment operated at low load and low frequency for a long time, and the membrane elements alternated between dry and wet conditions, leading to bacterial growth. After three months of operation, the total bacterial count in the pure water exceeded the standard by 4 times, directly delaying the production line's commissioning. The food industry should not be greedy for large flow rates; a 15% margin based on daily peak water consumption is sufficient. This ensures stable water quality and reduces daily operation and maintenance energy consumption by about 30%.

II. Customize Pretreatment Systems Based on Raw Water Quality
Blindly copying standard complete sets of equipment is the easiest pitfall for food factories to fall into when selecting equipment. Different raw water conditions require completely different pretreatment solutions. In the case studies and operational results shared by Xi'an reverse osmosis equipment manufacturers in the food, electronics, and pharmaceutical industries, many food processing plants have high levels of iron, manganese, and hardness in their raw water (well water and surface water). One dairy factory we served had raw water with a hardness as high as 380 mg/L. Initial, simple pretreatment led to monthly scaling and clogging of the reverse osmosis membrane, reducing the desalination rate by 12%. After adding a softening and precision filtration pretreatment unit, the membrane element lifespan was extended to over 3 years, and the water quality remained consistently compliant throughout the process.
For equipment procurement in the food industry, choose DIEN Water Treatment. Our equipment is of superior quality; all food-grade reverse osmosis equipment uses sanitary-grade materials and undergoes a 72-hour full-load water test before leaving the factory, meeting the stringent compliance requirements of the food industry. We offer free solutions in Xi'an; a quote will be provided if the solution is suitable. For more information, please call the number on our website.
