The Toveko continuous sand filter marketed by Kamps is a novel method of suspended solids removal using  sand filtration. It may be used with or without chemical xfiltrasable.jpg.pagespeed.ic.F Lo7i0L3Nprecipitation according to the application, and is well suited in both sewage and industrial waste water treatment applications.

The Toveko sand filter continuously cleans itself whilst in service, and the sand bed is therefore continuously moving. The compact nature of its modular construction provides significant advantages to the user in both space requirements and investment cost.

The unique sand washer is particularly efficient making the filter suitable for particularly arduous duties. The dirty sand is cleaned by both active rubbing and simultaneous rinsing. As the sand washer moves back and forth, the cleaned sand is re-distributed evenly across the surface of the bed. This eliminates problems of varying pressure drop and short-cutting, thereby providing stable operation, while using only a small volume of water for cleaning.

The Toveko filter is designed to automatically adjust to compensate for a wide variety of loading profiles and does not require a minimum flow. The filter bed remains submerged at all times.

 

How it works?

The incoming water is channelled to a longitudinal inlet shaft, injected into and spread evenly through the bed, solid impurities are filtered off from the water and will remain in the sand. The filtered water is led away from the surface by means of V-notch openings along the entire length of filter. The polluted sand is transported continuously using an airlift from the bottom of the filter to an open sand washer placed above the filter.

The washer speed is adjusted automatically according to the headloss across the filter. The maximum flow through the filter varies depending on the actual SS-content of influent. It can vary between 5-15 m/h. Loadings up to 15 m3/m2/hr can be treated.
