Ensuring high-quality treatment of industrial effluents is the number one task at any enterprise. We offer you to ensure the safe operation of your enterprise by installing an industrial wastewater treatment system, the most efficient of which is the Sengilei flotation device.
"Sengiley" is a wastewater treatment plant that is installed at industrial enterprises for wastewater treatment and purifies wastewater from various types of pollution:
Treatment of industrial effluents with the Sengilei flotation device has a number of advantages:
The principle of operation of the Sengilei flotator:
The basic principle of operation of the flow-through flotator "SENGILEY" is to saturate a certain part of the purified water with air and then mix it with the purified water in the flotation compartment 1.
The pressure flotation process consists of two stages: at the first stage, the water is saturated with air using pressure, at the second stage, the dissolved gas is released under atmospheric pressure. As a result, due to the formation of numerous air bubbles on the surface of pollution, the formation of flotation complexes occurs. They rise to the surface of the liquid, thereby forming flotation sludge.
The recirculation process leads to the fact that purified water (in the amount of 30-50% of the total volume) enters the saturation system. In it, the process of dissolving air in a liquid begins. Further, by means of the injection system, saturation water, already saturated with air, enters the tank of the skimmer, after which it is distributed throughout the flotation zone. In the process of getting into the zone of abrupt discharge, air comes out of the water in the form of microscopic bubbles. They mix with contaminated waste water, after which they adsorb elements of coagulated contaminants on the surface (oil products, suspensions, fats, etc.).
During the movement of water in the flotation compartment, sedimentation occurs, here heavy mineral impurities sink to the bottom of the flotator in the form of sediment and collect in the conical part, and small air bubbles float upward along with adhering elements of pollution, as a result of which a layer of foam forms on the surface - flotation sludge.
After that, complexes with a low lifting force in conjunction with a water flow are supplied to the thin-layer clarification unit 8. Here, in confined conditions, the process of coalescence of air bubbles occurs, as a result of which the lifting force of these complexes increases.
At the final stage, the purified water is supplied to the overflow pocket and is discharged through the nozzle 6.
The foam generated in the process of water purification contains particles of contamination - it is removed from the surface of the skimmer using a scraper conveyor, dumped into a sludge pan and removed through a branch pipe 5 into a special storage device.
Sediment settled to the bottom from the conical part 32 is regularly removed using a tap and a pipe 4.
The process of commissioning the Sengiley system:
Maintenance process of the Sengiley system:
The equipment should be inspected daily in order to detect the presence of malfunctions and any damage in time.
Check the operation of the air supply and recirculation pump daily.
It is necessary to remove sediment from the cone part of the skimmer on a daily basis in order to prevent its compaction.
Every two days, it is necessary to check the correct operation of the motor-gearboxes of the scraper system, as well as control the speed and correct rotation of the scrapers.
The bearings of the saturation pump shaft should be lubricated with a special compound once a week.
When the unit is operating in auto mode, the degree of tension of the chains of the scraper mechanism should be checked at a frequency of at least once a week. If slack is found, it is necessary to tension the chains using a tensioner to prevent skewing of the shafts of the sludge remover and other problems in the operation of the system.
Once or twice a year, you need to rinse the skimmer tank with clean water, as well as clean it from dirt and grease.
