Phage Technology in Sewage Treatment

Human demand for safe drinking water is rising, but water resources worldwide are limited. In order to alleviate this difference, the effective treatment and reuse of wastewater have become more and more important. Wastewater is a hotbed of many pathogens and may pose a threat to human health through various water transmission channels. Therefore, there is an urgent need for a simple and effective method to monitor and treat wastewater. As a bacterial virus, phages are the most widely distributed and most abundant organisms in the biosphere. Because they can specifically infect bacterial hosts, they have recently been used as new tools to control water pollution. phages play an important role in monitoring pathogens, tracking pollution sources, treating pathogens, infecting cyanobacteria that form blooms, and controlling sludge expansion and biofilm pollution in wastewater treatment systems. Phages also have limitations in controlling water pollution, including phage-mediated horizontal gene transfer, the evolution of bacterial resistance, and the reduction of phage concentration.

Solutions

Our researchers can help you achieve greater success with wastewater treatment solutions. We have professionals who listen to your needs carefully, and they can provide you with comprehensive support before, during, and after your experiment. We can provide these solutions listed as follows:

  • Monitoring pathogenic bacteria in wastewater

In the electrochemical biosensor method, phages are immobilized on the surface of electrodes and used as biometric identification elements to detect bacteria. Phages are easy to obtain and are more resistant to harsh environments. More importantly, their high selectivity can distinguish living cells from non-living cells.

  • Monitoring viruses in water and wastewater

The phage indicators we used in monitoring viruses are mainly divided into three groups: E. coli phages, Bacteroides spp. phages, and Enterococcus phages.

  • Tracking human fecal source

We provide the source of fecal pollution identification, in order to accurately conduct risk assessments and specify management strategies.

  • Treatment of pathogenic bacteria found in wastewater

As safe, efficient, and low-cost biological control agents, phages can be used to treat specific pathogenic bacteria in sewage. we provide custom phages as biological control agents.

  • Controlling bloom-forming cyanobacteria

Flowering cyanobacteria produce cyanobacteria toxins, which are harmful to the surrounding wildlife and aquaculture animals. The cyanophage has strong specificity and high lysis efficiency. Therefore, Creative Biolabs provides the discovery, separation, and purification of cyanophage for cyanobacteria.

  • Treatment of activated sludge bulking and foaming

Creative Biolabs provides phage-based technology to deal with the sludge bulking and foaming problems

  • Treatment of biofilm pollution using phages

The existence of bacterial biofilms causes the net flow rate of wastewater through the membrane surface to continuously decrease, and we attempt to apply our knowledge and technologies to solve this problem.

Water Quality Parameters Evaluation

We will evaluate the water quality parameters such as pH, temperature, turbidity, fecal coliforms, dissolved oxygen, total phosphates, biochemical oxygen demand, and total solids, and then make a design for your sewage treatment.

Our Technologies

  • Electrochemical impedance spectroscopy (EIS) is a commonly used method for phage-based electrochemical detection of bacteria.
  • The phage-based electrochemiluminescent biosensor will be applied in pathogenic bacteria monitoring.

Creative Biolabs can meet the needs of customers by providing sewage treatment solutions on time and on budget. We have in-depth knowledge and experience of the tools and processes involved in the phage projects. Our skilled and dedicated scientific researchers ensure that the most suitable methods and techniques are selected for your project. If necessary, please feel free to contact us.
