Cost savings

The installation of a Siljan PolySave gives the following advantages:

Lowered operational costs through reduced polymer consumption, valid especially when the following factors are fluctuating:

The use of Siljan PolySave will reduce the consumption of polymer with approximately 25-50%, as the operator often turns up the polymer dosage to be on the safe side, with as much as 20%. This has also been shown in practice.
The DS-content of the thickened sludge is more easily controlled, which in turn yields a higher average DS-content in a digester or de-watered sludge.
The sludge thickening system is shut down when the DS-content of the incoming sludge is below a set value, 0,5% as an example. When the DS-content rises above the set value the system is started up again. This function will save electric energy and reduce fresh-water as well as polymer consumption.
Reduces the amount of work for the operator.
Will give a more reliable unmanned 24 hour/day operation
