Power-thrifty SAFs perform

Premier Tech Water and Environment has enhanced its range of Rewatec 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. 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 componentry 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.

Uniquely engineered from robust GRP, the Rewatec SAF can cater for commercial businesses and residential communities with a population of up to 600 people. Bespoke designs are also available. Designed, manufactured and tested in accordance with EN12566-3 for plants below 50PE, EN12255 for plants above 50PE and the British Water Code of Practice for Flows and Loads, the Rewatec SAF is capable of meeting strict effluent standards that exceed UK environmental discharge requirements, for on-site applications that don’t have access to the main sewage network.
