ZeeWeed* Membrane Bioreactor (MBR): an innovative solution for wastewater treatment in the food & beverage Industry

The food and beverage industry is faced with the challenge of managing large volumes of wastewater generated from various processes, such as cleaning, rinsing and product processing. This wastewater often contains high levels of organic matter, suspended solids and other contaminants, making it crucial to implement effective treatment solutions that not only meet environmental regulations but also promote water reuse and sustainability.

ZeeWeed Membrane Bioreactor (MBR) is a cutting-edge wastewater treatment solution developed by Veolia Water Technologies & Solutions, a global leader in environmental services, that combines the power of biological treatment with advanced membrane ultrafiltration, offering a comprehensive and reliable solution tailored to the unique needs of the food and beverage industry.

How it works?

At the core of the ZeeWeed MBR system lies the suspended growth bioreactor, where microorganisms break down organic matter and contaminants present in the wastewater. However, unlike traditional activated sludge processes, the ZeeWeed MBR employs best-in-class membrane ultafiltration units, featuring robust braided PVDF hollow fiber membranes.

These membranes act as a physical barrier, allowing only the treated water to pass through while retaining the activated sludge and other suspended solids within the bioreactor. This results in an exceptionally high-quality effluent, with very low levels of suspended solids, bacteria and other contaminants, making it ideal for water reuse or discharge into sensitive receiving waters.

One of the key advantages of the ZeeWeed MBR technology for the food and beverage industry is its compact footprint and modular design. The submerged membrane configuration, where the membrane modules are immersed directly in the activated sludge tank, minimises the overall plant footprint, making it easier to integrate into existing facilities or new construction projects.

Moreover, the ZeeWeed MBR system is designed to handle varying wastewater flows and loads, a common challenge in food and beverage processing operations. Its flexibility, modularity and scalability ensure efficient treatment, even during peak production periods or when dealing with fluctuating wastewater characteristics.

ZeeWeed MBR key advantages

1. High-quality effluent
   The ZeeWeed MBR system produces exceptionally high-quality effluent with very low levels of suspended solids, bacteria and other contaminants. This makes it suitable for applications where stringent discharge standards or water reuse requirements need to be met.
2. Compact footprint
   The submerged membrane configuration, where the membrane modules are immersed directly in the activated sludge tank, results in a compact footprint. This allows for easy integration into existing facilities or new construction projects with limited space.
3. Modular and scalable design
   The ZeeWeed MBR system is designed with a modular and scalable approach, enabling it to accommodate varying wastewater flows and loads. This flexibility is particularly beneficial for industries with fluctuating production levels, such as the food and beverage sector.
4. Robust membrane materials 
   The ZeeWeed membrane modules are constructed using durable materials like polyethylene or polyvinylidene fluoride (PVDF), which are resistant to chemical and biological degradation, ensuring long-term performance and reliability.
5. Advanced cleaning mechanisms 
   The system incorporates advanced cleaning mechanisms, such as air scouring, suction relaxation and periodic backwashing, to mitigate membrane fouling and maintain consistent filtration performance over time, reducing maintenance requirements and operational costs.
6. Water reuse and recycling 
   The high-quality effluent produced by the ZeeWeed MBR system enables water reuse and recycling opportunities, contributing to water conservation and resource efficiency.
7. Reduced sludge production 
   Compared to conventional activated sludge processes, the ZeeWeed MBR system typically produces less sludge, resulting in lower sludge handling and disposal costs.
8. Proven technology 
   The ZeeWeed MBR technology has been successfully implemented in numerous wastewater treatment projects worldwide, demonstrating its reliability and effectiveness across various industries and applications.
9. Sustainable solution 
   By enabling water reuse, reducing sludge production, and minimising the environmental impact of wastewater discharge, the ZeeWeed MBR system aligns with sustainable practices and contributes to a circular economy approach.

Summary

By implementing the ZeeWeed MBR technology, food and beverage companies can not only meet stringent environmental regulations but also achieve significant cost savings through water reuse and recycling. This sustainable approach aligns with the industry's growing focus on reducing its environmental footprint and promoting circular economy principles.
