Packaged Drinking Water Production Line & Production Process Guide
Packaged drinking water, represented by purified water, natural mineral water and spring water, is one of the most demanded beverage products worldwide with stable market demand. Zhonglian Machinery supplies fully automatic packaged drinking water production lines integrating water purification, sterilization, filling and packaging. With mature RO membrane treatment technology and reliable aseptic filling process, the lines are compatible with multiple packaging formats and cover capacities from small-batch to large-scale manufacturing, widely applied in water plants of all scales.
RO Reverse Osmosis Water Treatment Process Flow Chart
1. Raw Water Multi-stage Pre-treatment
Raw water passes through sand filtration, activated carbon filtration, ion exchange softening and precision filter. It removes sediment, chlorine and scale ions to protect the follow-up RO membrane.
2. Core RO Reverse Osmosis Purification
High-pressure multi-layer RO membranes filter heavy metals, salts, bacteria and organic impurities, desalination rate over 98%. Built-in CIP cleaning keeps long-term stable running.
3. Dual Sterilization & Terminal Fine Filtration
UV + ozone double sterilization eliminates microorganisms completely. Front-end security filter intercepts tiny pipeline impurities to guarantee sterile pure water storage.
4. Aseptic Storage & Supply for Filling Line
Sterile pure water is stored in sealed pure water tank, delivered via dedicated pipelines to filling equipment, avoiding secondary bacterial pollution before packaging.
