Rewatec - Moving bed biofilm reactor (MBBR) smaller, smarter plants

Wastewater treatment is a fundamental step in ensuring environmental water quality. To achieve this, plants with complex treatment processes are required. This often requires large volume tanks (footprints) with associated capital expenditure and is typically linked with elevated carbon emissions.

Generally, increased demand in water quality, leads to major expense from sizeable plants that effect both land and energy.

Footprint/Land optimization

Smaller plants would be a preferred option to minimize land utilization. Premier Tech Water and Environment (PTWE) were able to decrease the overall footprint by incorporating in-house bio-media to enable high bacterial concentrations in smaller volumes (both aerobic as standard, and anoxic when required (nitrates removal-total nitrogen)).

Specifically, a plant’s biozone can be reduced by up to 50%, reducing respectively not only the size of the installation, but also the investment of the land required (optimizing land-use).

Aeration optimization

The Rewatec MBBR arrangement can incorporate electro-mechanical equipment that optimizes aeration, resulting in an efficient and cost-effective operation. The end user should expect up to 50% reduced costs to their electricity bills. This cost reduction would not only enable a quick return on investment but will also assist in water sustainability by reducing the carbon footprint of the application. This add-on product is ideal for applications where the loading is expected to vary (i.e. holiday homes, caravan parks etc.).

Desludging optimization

The Rewatec MBBR arrangement can incorporate electro-mechanical equipment that also optimizes desludging. The plant can be desludged only when the level is high, rather than at specific time intervals. We provide a ‘technology’ able to reduce sludge frequency and inform the end-user when emptying is necessary. This not only reduces service costs, but also minimizes the operational carbon footprint of the plant.

* other plants of our range can have these probes as optional
