Abstract

The main objective is to deliver a solution capable of achieving great energy savings in WWTPs with minimum costs. A new type of aeration system based on diffusers with high endurance and reliability made from corrosion resistant metals will be developed. Several fine bubble diffusers (with 0.3 0.5 mm apertures) will be realized with an unconventional method (electroerosion) and tested in laboratory conditions. After this stage, the best aeration system will be tested in situ in 4 WWTPs (2 in Romania and 2 in Turkey) and the efficiency of the dissolved oxygen mass transfer will be determined. The new type of diffuser will be tested in 2 Conventional Activated Sludge (CAS) WWTPs and in 2 WWTPs that has implemented the Moving Bed Biofilm Reactor (MBBR) technology. An ultrasound system will be mounted, on each aeration system, to prevent diffusers clogging. Furthermore, a new shape and material will be proposed for the realization of biofilm carriers to increase the biological treatment efficiency.

Needs Addressed

The power consumption in urban and industrial WWTPs has increased considerably during last decades due to the higher volume of treated wastewater. Energy consumption is the largest budget item of a European WWTP.

The energy demand in this sector will probably increase in the near future because of population growth and because of the need to comply with stricter European regulations in the field of water treatment, generating more energy intensive processes. Furthermore, the generation of greenhouse gasses (GHG) has become important for wastewater treatment. So, CEBIOTREAT is addressing to this general problem of power consumption in WWTPs and try to minimize the negative effects on the environment. Beside the power consumption, another widespread problem of the WWTPs with fine bubble diffusers is related to their maintenance.

Maintenance activities for elastomer diffusers should be monthly and yearly scheduled as follows:

  1. Monthly. Increase the air flow to the diffusers 2 to 3 times normal for about 15 minutes to blow out the biological growths that have accumulated around the diffuser orifices. As a result, the power consumption is greater.
  2. Yearly, or as conditions warrant. Diffusers that are allowed to remain in a defective condition reduce the diffusers’ effectiveness and will result in inefficient wastewater treatment. Also, an increased efficiency of the biological stage, due to the new biofilm carrier, will lead to a reduced footprint for the entire WWTP.

Estimated Results

  • 10 types of air diffusers (with 0.3-0.5 mm apertures) made from corrosion resistant metals
  • 1 ultrasound system to prevent diffusers clogging
  • 1 automation system
  • 1 new shape and material will be proposed for the realization of biofilm carriers to increase the biological treatment efficiency
  • 2 patent requests
  • 2 ISI articles published/accepted for publishing

CEBIOTREAT Project Objectives

The main purpose of CEBIOTREAT is to reduce the energy consumption in wastewater treatment plants (WWTPs) by 20% for conventional activated sludge WWTPs and by 40% for Moving Bed Biofilm Reactor (MBBR) WWTPs and to increase the efficiency of the biological stage.

A new type of aeration system based on fine-bubble diffusers with high endurance and reliability made from corrosion resistant metals will be developed.  The diffusers will be realized using electroerosion.  Also, CEBIOTREAT proposes a new automation solution for the aeration system, with mobile phone control. The diffusers will be designed to be use in all biological treatments, especially for the MBBR process, first developed in Norway (Ødegaard, 2013). The fine-bubbles diffusers will be also tested for conventional activated sludge WWTPs. The MBBR process needs a special aeration system because the biofilm carriers are floating inside the wastewater mass and butting the aeration system. More than that a new type of biofilm carrier will be designed and tested together with the new aeration system. The new biofilm carrier, proposed by CEBIOTREAT, will lead to an increase efficiency of the biological treatment stage.

In conclusion, the overall aim of CEBIOTREAT is to deliver a solution capable of achieving energy savings in WWTPs with minimum costs together with an increased biological treatment efficiency.
