Indion - Lamella Clarifier
From Drinking Water Treatment - Clarification
The INDION lamella clarifier provides an effective answer for the clarification of water and waste water. The lamella clarifier achieves solid-liquid separation by directing the liquid between a series of inclined plates called lamella. The settling surface of each plate is equivalent to its horizontal projection. Lamellas are normally spaced approx. 50 mm apart, with the result that large settling surfaces are concentrated within a relatively small floor area.
Product Details
Stacking the inclined plates results in the separator having up to ten times the clarification area of a conventional circular settling tank occupying the same floor space. In other words, for the same liquid flow, the lamella clarifier would occupy 1 /l 0'' of the floor area of a conventional clarifier.
A number of standard sizes are available, sizes designated by the settling area. The capacity for each size depends on the type of solid being separated and can be determined experimentally using settling tests.
Application
- Ash/scrubber waste treatment
- Brine clarification
- Clarification of water
- Coal and other mineral separation
- Filter backwash water recovery
- Food and dairy processing and waste treatment
- Iron removal
- Metal hydroxides separation
- Mill scale separation
- Municipal water and waste treatment
- Phosphorous acid waste treatment
- Plating and finishing waste treatment
- Semi-conductor process waste treatment
- These are the major applications. However, lamella clarifiers can be used in almost every industry for solid-liquid separation.
