Premier Tech Water and Environment has enhanced their range of Rewatec submerged aerated filter (SAF) sewage treatment plants to combine energy efficiency with an exceptionally high wastewater treatment performance.
As part of the redesign, the Rewatec SAF now features an internal baffle in the primary chamber to assist with the removal of solids and organics, and to prevent potential blockages downstream.
A new pipe arrangement to optimise the level of oxygen induced into the biozone chamber, also improves the operational efficiency of wastewater treatment. Other unique attributes such a simpler manifold design and a new manifold extension kit increase the overall reliability of the plant, whilst also making it easier to install, commission, service and maintain.
All Rewatec SAF plants are supplied with a robust kiosk to house the electronic and mechanical components required to operate the system. Innovative features such as temperature and pressure alarms and air filter monitoring are included as standard, with options such as acoustic lining and GSM and/or BMS communication for remote plant monitoring, available upon request.
A variable speed three phase blower to increase efficiency, reduce energy usage, reduce costs and lower the overall carbon footprint, can be installed within the kiosk on all plants above 100 PE. An optional probe can also be supplied to regulate the air supply in the biozone chamber, again maximising energy efficiency whilst reducing cost for the end user.
Dr Evangelos Petropoulos, Premier Tech Water and Environment's senior technical engineer, commented:
“As an environmental company we have the moral obligation to protect our water resources and pass them to our children in a state better than that we had received from our ancestors. To ensure a more sustainable future, we continuously develop more efficient, more reliable, and easier to operate wastewater treatment systems. To further enhance this commitment and to provide the best-in-class product, we are proud to release our new generation of SAF wastewater treatment plants.
This is only possible due to the strong relationships we have with our customer partners, many of whom were heavily involved in every aspect of development. The feedback they provided in terms of technical requirements, operational efficiency, installation and design were all carefully considered. This has resulted in a highly efficient and highly reliable system that has surpassed their expectations.”
