This spring, an ESMIL rotary drum screen was installed at the facility of one of the UK’s leading producers of jams and fruit-based food products. The supplied unit was an RDS 0610 model with a 2 mm screen opening, designed for outdoor installation.
The Role of Drum Screens in Food Processing Wastewater Treatment
Process wastewater generated during fruit and vegetable processing contains high concentrations of suspended solids and debris such as seeds, peels, pulp, and fruit residues. Effective removal of these contaminants at the mechanical treatment stage is essential for the stable operation of downstream treatment processes.
The ESMIL drum screen installed at the facility is responsible for removing these solids before the wastewater enters subsequent treatment stages. The 2 mm screening surface effectively captures the fine particles typically found in wastewater generated during jam production.
The unit was designed to handle a flow rate of 20 m³/h and process up to 1 tonne of screenings per week.
Self-Cleaning System for Stable Operation
Due to the nature of wastewater generated in the food industry, mechanical screening equipment can be exposed to the accumulation of solids and the risk of screen clogging.
The ESMIL drum screen is equipped with a scraper mechanism and a spray nozzle cleaning system that continuously remove accumulated solids from the screening surface. This helps maintain stable and uninterrupted operation, which is particularly important in food production facilities.
ESMIL Drum Screens for the Food Industry
ESMIL drum screens are designed for the preliminary mechanical treatment of wastewater generated by food processing plants. Typical applications include:
- Meat processing facilities
- Dairy plants
- Fruit and vegetable processing plants
- Beverage production facilities
