Grading boxes
The screening box is a primary treatment organ that will retain all the larger solids present in the raw effluent, preventing these solids from entering treatment organs such as grease traps, septic tanks and ETARs.
Equipped with a bar grid, inclined at 45º, in galvanised steel, with a bar spacing of 25mm, it also has a basket for the draining of graded products.
They have total leak tightness, low weight, high chemical resistance, high mechanical strength and insensitivity to corrosion.
It has two full opening lids, for easy cleaning of the equipment, with locks.
