Wastewater Water Treatment

We have worked on a wide range of wastewater treatment processes around the world. Serval hundred aeration blower and full aeration systems have been designed using Rockwell, Siemens, Mitsubishi, Schnider, GE control equipment. The control systems include energy saving techniques and high availability to provide efficient, robust and reliable solutions.

 

Wastewater Processes:

  • Pumping station controls
  • Inlet and screening processes
  • Primary Settlement and desludging
  • Controls for activated sludge processes
  • Aeration and Blower Control
  • Sequential batch reactor (SBR)
  • Tertiary treatment including filters and UV systems
  • Sludge thickening and pressurization
  • Digestion processes
  • Thermal sludge dryers
 

Major projects Include:

 

Ringsend Wastewater Treatment Plant, Dublin, Ireland. Worked closely with the EPC contractor to complete this 200 million Euro project including the upgrade and replacement of the inlet works, automating the 4 Jenbacha gas engines to provide standby power including island mode. Upgrade three Swiss Combi thermal dryers after one of the dryers experienced a dust explosion. Ringsend Wastewater Treatment Plant, Dublin, Ireland.

Zandvliet sewage treatment works, Cape Town, South Africa.

 

Papermill effluent treatment plant, Tasmania.

 

Meary Veg thermal sludge dryer, Isle of Man. We implemented design changes and re commissioned a Vandenbroek thermal sludge dryer to implement safety systems and ensure the dryer met ATEX regulations. The control system was based on the Mitsubishi range of PLC and SCADA system.

 

Pyewipe Sewage Treatment and Thermal dryer, Grimsby, England. Design, develop, test and commission Allen Bradley PLCs and Intouch SCADA system for the sewage treatment, sludge treatment, digestion and thermal sludge dryer.

 

Peaceheaven Wastewater Treatment Works, Brighton – implemented a large Mitsibushi control system covering the powering stations and the Waste Water Treatment process. The SCADA system was implemented using the Wonderware Intouch SCADA package.
