“Voronezhsintezkauchuk” is one of the leading producers of high-quality rubber, latex and thermoelastolayer in Russia. A tour to its treatment facilities happened in April, 2011.
At the entrance.
Some treatment processes occur inside the building while others are carried out outdoors.
The complex has been designed for “Voronezhsintezkauchuk” solely and it doesnâ€™t apply to the municipal sewage system. One of its supply pressure lines is 700 mm in diameter (the second one is backup).
First of all, wastewater gets to its mechanical treatment department that includes 4 wastewater mechanical treatment units Rotamat Ro5BG9 by HUBER (3 working and 1 backup). The conveyer delivers waste and sand to the ground of solid domestic waste.
After that, this water goes to a sewage regulator. There are two of them here.
The sewage regulators are equipped with mechanical wastewater mixing systems of a capacity of 7,580 m3.
After that, the water is pumped to skimmers.
The skimmers are 4 flotation installations (3 working and 1 backup).
They are used for saturation and coagulant supply to remove latex and other suspended particles.
Pressure flotation is used to separate light suspended particles or emulsion from liquid phase by means of air bells and reagents.
They also use cationic flocculant, for example Zetag 7689 (about 0.8 g per 1 m3), to make flotation more effective and reduce reagent consumption.
In the sludge drying department.
