Hydrok redesign the SAF Package Biological Treatment Plant Traditional SAF (Submerged Aerated Filters) have long been accepted as a cost effective biological treatment solution within the UK Water Industry and industrial applications alike. However, they can suffer from two problems – the biological media can be prone to clogging, and they are generally power hungry. In essence, SAF design has remained very much unchanged over the last 20 years or so.
efficiencies compared to traditional block media and coarse aeration.
With this in mind, Hydrok and Atac have taken a fresh look at the design of SAF’s in light of the technology now available within the wastewater treatment industry. The outcome of their review led them to develop and design a new type of Package Treatment Plant called the Hydrok/Atac HY-SAF - a hybrid package SAF that can be used as a permanent or temporary hire solution.
In order to minimise power costs, control software is 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. This results in power savings of up to 35%, compared to conventional SAF units, and with no moving parts in the main tank, HY-SAF is simple to operate and low in maintenance.
The Cleartec Biotextil media, unlike traditional block or random packed media, does not retain sludge and dead biomass which can reduce the effective surface area and treatment efficiency. All solids are kept in suspension to be passed on for downstream settlement. As a result, there are no blockages, and no need to de-sludge the SAF cells.
At the heart of HY-SAF are the Hydrok IFAS (Integrated Fixed-Film Activated Sludge) modules combining highly efficient Aquaconsult AEROSTRIP fine bubble diffusers with well proven IoW Hydrok HY-SAF 26/1/12 Cleartec Biotextil media which1/2pg offers far greater
