Membrane Bioreactors (MBR) have become the preferred method to treat wastewater when a high-quality effluent is required. Effective pretreatment of the influent to these systems is imperative to reduce or even eliminate the risk of damage to the costly membranes. Fine screening is the primary focus for many facility operators as it is the first line of defense for the MBR system and is responsible for maintaining the efficiency and operability of the system. Protecting delicate and expensive membranes from damage by hair, fibers, and other small particles is a key consideration when designing and operating a membrane process.
The global leader in fine screening and membrane protection.
MBR & Fine Screening Treatment Products
RotoSieve Drum Screens are an extremely effective and economical method to remove solids from wastewater, especially when an MBR system is involved. Screening out solid matter including hair/fibers from the wastewater will enhance the MBR treatment process and protect the membranes from damage. Several advantages provided by the RotoSieve design ensures a high performing and reliable MBR system:
- No vertical or slotted seals of any kind that would result in bypass – all flow must pass through a perforated hole to reach the downstream process. No seals that can fail resulting in membrane damage.
- Overflow bypass and alarm system detects and separates unscreened flow during an overflow or blinding event. Protects sensitive downstream processes like membranes from damage caused by unscreened flow.
- The innovative and proprietary drive system eliminates the need for trunnion wheels. This significantly lowers required maintenance and improves reliability.
- Guaranteed removal of all solids larger than the drum perforation.
- Highly efficient at removing small chain fibers and hair that damage membranes
- Guaranteed that no material will weave or staple into the perforated drum screen element causing permanent blinding.
- The RotoSieve can also perform double duty and screen recycled activated sludge (RAS). This helps improve the performance and operation of the MBR system in the long term.
- Unparalleled Experience – Thousands of installations around the world and hundreds of installations protecting various membrane systems.
Besides the RotoSieve Screen, other products can be packaged together to create a full pre-treatment/protection system for a MBR system. This includes the following:
- SCP Shaftless Screw Press – Screenings can be further dewatered and compacted using the SCP Shaftless Screw Press. The press catches the screenings straight from the RotoSieve and compacts, dewaters, and transports the screenings.
- SC Shaftless Screw Conveyor – If transportation is the only concern for the screenings, the use of our Shaftless Screw Conveyor fits the job.
- Grit Classifier – Remove grit/sand from the influent in low to medium flow applications to further protect your membranes.
- PTU Complete Plant – Include a RotoSieve screen with a PTU Complete Plant to have a turnkey fine screening, grit, and optional FOG removal system that provides effective protection of a MBR system in an easy to install package.

As the world population continues to grow, so does the demand for clean water. However, traditional wastewater treatment methods are not capable of keeping up with this increase in demand. This is where MBR treatment comes in – an innovative technology that holds great promise for the future of wastewater management and sustainability. In this blog post, we will explore everything you need to know about MBR treatment and how it can help us create a more sustainable future for generations to come. So whether you’re a curious citizen or an industry expert looking for new solutions, read on to discover why MBR treatment is shaping up to be one of the most important developments in modern wastewater management!
What is MBR Treatment?
The MBR treatment process is a wastewater management technology that uses anaerobic bioconversion to break down pollutants and convert them into harmless byproducts. The MBR process is considered to be more sustainable and environmentally friendly because it does not rely on the use of water or energy, and it can also be used in areas with limited resources.
The Advantages of MBR Treatment
The MBR treatment process is a newer and more efficient wastewater treatment technology that has many advantages over traditional wastewater management practices. MBR processes use anaerobic digesters to break down organic material, removing pollutants like nitrogen and phosphorus from the water. This system has several benefits that make it a popular choice for wastewater treatment:
MBR Systems are More Efficient than Traditional Wastewater Management Practices:
One of the main advantages of using an MBR system is that it is much more efficient than traditional wastewater management practices. Traditional wastewater management methods rely on stopping the flow of water once it reaches a designated body of water, like a river or lake. This approach requires large amounts of energy to stop the flow, which can be costly both in terms of money and resources. An MBR system, on the other hand, uses anaerobic digestion to break down organic material in the wastewater stream. This process not only removes large amounts of harmful pollutants like nitrogen and phosphorus, but it also produces methane gas as a byproduct. Methane is a powerful greenhouse gas that contributes significantly to climate change, so using an MBR system instead of traditional wastewater management practices can help reduce environmental impact overall.
