1. Introduction. High-strength wastewaters produced in industries need intensive treatment before its safe disposal to the environment (Zhang et al., 2024, Maaz et al., 2024).Anaerobic processes are normally preferred in degrading the organics present in high-strength wastewaters (Song et al., 2024, Li et al., 2024).Biological treatment processes, however, are not considered for wastewaters

Wastewater treatment challenges in food processing
Wastewater generated from food production and agricultural activities is a major source of environmental pollution. It is also among the most difficult and costly waste to manage because food processing wastewater can contain large quantities of nutrients, organic carbon, nitrogenous organics, inorganics, suspended and dissolved solids, and it has high biochemical and chemical oxygen demands.

How to reduce COD in wastewater. Primary and secondary treatments remove around 75-85% COD, but the hard-to-treat COD remains. Typically, legislation for COD discharge is from below 120 mg/L in the EU to below 50 mg/L in China and therefore in order to meet regulatory standards, additional treatment is often required.

Get Price- How do you control Legionella in cooling water systems?
- Controlling the risk of microbial growth To reduce contamination by Legionella in cooling water systems and the risk of its dispersal into the air, attention must be paid to design, installation, operation, and maintenance.
- Are cooling towers prone to Legionella?
- Legionella risks are similar for open and closed-circuit cooling tower systems. Sediment and biofilm, temperature, water age, and disinfectant residual are the key factors that affect Legionella growth in cooling towers. All cooling towers use the evaporation of water to remove heat and release it into the atmosphere.
- How do you prevent Legionella in a cooling tower?
- Scale, corrosion, sediment controls, and system cleaning are critical for cooling tower operations and Legionnaires' disease prevention. Disinfectant residual should be monitored and adjusted by an automated system. Legionella can grow and spread in both open- and closed-circuit cooling tower systems. Use this document to:
- What if Legionella is detected in bleed water storage system?
- The appropriate interventions for unacceptable bacterial counts in the bleed water storage system are outlined in Appendix 3. If Legionella are detected in cooling tower at levels >10CFU/mL the supply of bleed water to the storage system shall cease until the levels in the cooling tower return to below 10CFU/mL.
