High Efficiency Package Biological Wastewater Treatment Plant

The ELIQUO HYDROK Hybrid Submerged Aerated Filter (HY-SAF) offers a power efficient, robust, small footprint biological wastewater treatment solution individually designed to achieve the final effluent consent standard required.

HY-SAF package treatment works are suitable for treating municipal wastewater for 100-3,000 PE (Population Equivalent) and industrial effluents - offering a complete turnkey package. With no moving parts in the main tank, the HY-SAF is simple to operate and low in maintenance. In order to minimise power costs, we incorporate control software linked to a highly efficient motor control centre, this ensures effective and accurate blower/air control delivery whilst maintaining the most efficient treatment process conditions.
