Project Overview

In the food processing industry, water is one of the most important production resources. It is widely used for ingredient preparation, product processing, equipment cleaning, steam generation, and sanitation. The quality of production water directly affects food safety, product consistency, equipment reliability, and compliance with international food manufacturing standards.

Located in an area with limited freshwater resources, a food processing factory in Algeria relied on brackish groundwater as its primary water source. Due to its high salinity and hardness, the raw water could not be used directly in production.

To solve this challenge, the customer partnered with Zhongnuo Water Treatment to install an 8T/H (8m³/h) Brackish Water Desalination System. Utilizing advanced Reverse Osmosis (RO) desalination technology, the system converts high-salinity groundwater into high-quality purified water suitable for food production, helping the customer reduce water costs while ensuring stable and safe manufacturing operations.

The customer required low-conductivity purified water suitable for continuous production.

3. Continuous Production Requirements

The factory operates multiple production lines throughout the day.

The system needed to provide:

· Stable 8 m³/h water production

· Continuous 24/7 operation

· Stable water pressure

· Reliable water quality

without interrupting daily production.

4. Energy Efficiency and Low Operating Costs

The customer expected a desalination system featuring:

· High water recovery

· Low energy consumption

· Automatic operation

· Reduced membrane fouling

· Easy maintenance

to minimize long-term operating costs.
