Zhongnuo Water Treatment designed and supplied a 4 m³/h Reverse Osmosis (RO) Water Treatment System for a food processing plant in Malaysia. Using municipal water as the feed source, the system provides stable, hygienic, and high-quality purified water for food production, ingredient preparation, equipment cleaning, and utility applications. The automated RO system helps improve product quality, reduce operating costs, and ensure continuous production.

• Maintaining consistent water quality for food manufacturing.
• Removing chlorine, hardness, suspended solids and dissolved salts.
• Ensuring 24/7 continuous water supply.
• Meeting food industry hygiene requirements.
• Reducing operating and maintenance costs.

Municipal Water  ->  Raw Water Tank  ->  Raw Water Pump  ->  Multi-media Filter  ->  Activated Carbon Filter  ->  Water Softener  ->  Brine Tank  ->  5 μm Cartridge Filter  ->  High-pressure Pump  ->  Reverse Osmosis (RO) System  ->  Pure Water Tank  ->  UV Sterilizer  ->  Water Supply System  ->  Food Production Water Points

The system integrates pretreatment, reverse osmosis, UV sterilization, and PLC automatic control into a compact skid-mounted design. It delivers stable purified water while minimizing operating costs and maintenance, making it ideal for food processing facilities.
