On a waste water treatment plant is known that the water follows a processes in series in which there are eliminated elements such as solid, fats, sands, matter organizes, muds, etc … …
The first process and very importantly it is the elimination of big and heavy solids or other elements like sand, stones, etc …. The bivalve Spoon CP is an equipment of hydraulic, simple operation of handling, simply to support with big resistance and hardiness, this equipment avoids big problems especially with the coarse screen that we can find in a waste water treatment plant for the separation of solids.
Usualy before this goes a pumping or before a course screen, in the mentioned well there are retained the elements bad for the automatic screen, such grids as bottles, woods, dead animals, wheels, bricks, stones, etc …. In the communication of this well and the later process usually goes a manual vertical screen of light beetween the bars around 80 and 100 mm, with this way all the solids with big sizes are eliminated by the bivalve spoon CP, also to indicate that big size sands or stones, etc …. Speed decant and eliminates the process by mediation of the bivalve spoon CP, this type of residue is very bad for the coarse screen and step screenn becouse the sand, the stone are material very abrasive and that improve the wear of the mobile pieces.
The spoons bivalve CP normally are operated by manual way once a day, so that means that you decrease, closing and elevation, the bivalve spoon CP, the spoon will be the whole day in the top part in what we will name ” “DRAINED” “, the following day previous new operation, the solid that remains in its interior would be directed the container totally exempt from water.
These equipments are made by capacity / volume, the smaller model is for a capacity of 100 liters and the bigest is for 2500 liters, they are made normally of Carbon Steel, but they can be made of stainless Steel by costumer request.
