We manufacture flotation units for round basins. In model C, waste water that has been thickened with chemicals is stirred using the slow stirring device in the middle of the basin. Dispersion water is prepared by ejecting air into the water in the ejector unit. The water then flows into a pressurised tank where the air is dissolved over the required dissolution time. Dispersion water can also be prepared in a special pump that mixes air with water. In this case, the dissolution time of air is reached in the extended pipe with a volume designed to match the required retention time. Dispersion water is fed into a space located outside the stirring basin that houses the nozzle piping for the dispersion water. The slow stirring device and the surface sludge scraper are operated using a shaft system with central traction. The water for the preparation of dispersion water is taken near the exterior wall where the cleanest water is available, or from a purified water basin placed after the flotation process.
Our other round flotation unit is model R in which the fast mixing basin and stirring basin are located outside the flotation basin. Dispersion water is prepared using the same methods as in model C. Dispersion water is fed into the pipe between the stirring basin and the flotation unit and distributed evenly into the basin using the distribution device in the middle of the basin. Bottom sludge and surface sludge scrapers are operated using a shaft system with central drive. The water for the preparation of dispersion water is taken underneath the cone inside the flotation basin where the cleanest water is available, or from a purified water basin placed after the flotation process.
