REWATEC ® SAF Sewage Treatment Plant 35 Population
Standard Features Include:• Integrated air Filter – draws in fresh air from the outside and flters any particles to protect the blower
• Pressure switch - air filter benefits from a pressure switch which monitors any pressure drop across the filter
• Blower pressure monitoring and protection – if a high pressure if detected, the blower will shut down and the alarm beacon will ash to notify the operator
• Automatic shut down and restart when high temperature is detected
Plant KioskREWATEC SAF products are provided with a mild steel kiosk. This kiosk houses the aeration blowers, timer valves and the electrical control panel.
The electrical control panel provides all the required electrical equipment for the starting, running and monitoring of the plant.
The control panel can be adapted to accommodate other mechanical and electrical devices associated with the plant, for example a final effluent pump station or UV disinfection.
The kiosk is fitted with an alarm beacon as standard and can be provided with telemetry for remote plant monitoring.
Other innovative features include thermostatic cut off controls and air filter monitoring to extend blower life.
How the REWATEC SAF WorksThe REWATEC SAF Treatment Plant comes in four variations, dependant upon population size and application parameters.
• Unitank (singular tank)
• Semi Modular Tank (two tank system)
• Modular (three tank system)
• Multi Stream Systems (bespoke application design)
The tank(s) form three treatment stages; primary settlement, biological treatment (biozone) and humus settlement. Flow through all of the treatment stages from inlet to outlet occurs through gravity and integral airlift.

From housing developments and other small scale projects right up to larger commercial applications including caravan parks, leisure facilities, hotels, schools, offices and industrial situations, the plant will serve a population from 30 – 600 PE as a single stream unit.
Larger populations can be accommodated with multiple stream plants.
Superior Technical Performance
The highly successful REWATEC SAF is designed and tested in accordance with BS EN 12566-3, the British Water Code of Practice for Flows and Loads as well as being CE approved.
In standard configuration the plant offers treatment better than a 20mg/L BOD:30mg/L SS: 20mg/L NHȝ effluent quality standard with options for 10 or 5mg/L NHȝ effluent quality and improved BOD and SS quality.
The REWATEC SAF Package Sewage Treatment Plant
Complete Below Ground Installation
Premier Tech Aqua has designed the REWATEC SAF to have a minimal visual impact on site location. This includes complete below ground installation, though the range is adaptable and can provide an above ground treatment solution when needed. The plant also offers a quiet, odourless operation which is assisted by a compact design with no below ground moving parts.
Low CostsThe REWATEC SAF offers superior technical performance at a competitive price, offering real value for money without compromising on quality. The plant is particularly quick and easy to install which results in low initial costs, but also uses reliable, cost effective and energy efficient blowers, for operation with an integral ow management system, providing an overall competitively priced product for the duration of its lifetime.
DesignPremier Tech Aqua has been the manufacturer
of hundreds of REWATEC SAF installations across the world and has pioneered the development of package sewage treatment plants.
The REWATEC SAF utilises a proven Submerged Aerated Filter (SAF) technology for optimum performance and dependability. The adaptable design offers the availability of pumped in effluent or effluent, deeper inverts and the availability of high nitrification options.
