SERTAMVIS screw sieves can be installed the same way as SERTELNVB, either in a channel or within a stainless steel casing.

The sieve diameter is selected following the water flow rate to be treated and the grid slot. The standard diameters are: 300, 400, 500 and 600 mm. Then, following the depth of the channel and the desired discharge height, the correct length is defined. Useful length varies by 0.5 m stretch, from 1.5 to 7 m and more

From 0.5 to 2 mm openings, we use a half-cylindrical (225°) grid (Johnson's) with triangular section wires. For larger openings up to 15 mm, we use perforated metal sheet.

ECOTAMVIS has an unique diameter of 200 mm, length of 500 mm only, and is really specific for small units of treatment with low flow rates, we restrict its application up to 20 m3/h, as every economical model of our range of equipments.
Util lengths are limited as well, by 0.5 m stretch, from 1.5 to 4.5 metres maximum.

Common options : external casing for bypass with manual screen, association with ECOCOMP / SERCOMP / SERCOMP+ compactor and automatic bagging system.
