TRIDAIR HORIZONTAL HYDRAULIC™
NATCO’s Tridair™ Horizontal Hydraulic Induced Gas Flotation (IGF) Unit is an oil/water flotation unit that is equipped with advanced features to ensure high efficiency operations and low operating costs.
In the IGF, oily water flows through four flotation cells, separated by over/under baffles to a clean water chamber. Some of the water is re-circulated back to one or more Radial Eductors™ located in each cell, which induce gas at controlled rates. The unique Radial Eductor design ensures even dispersion of the gas bubbles throughout the cells. By controlling the volume and rate of gas induced, the proper bubble size for efficient gas/contaminant interaction is produced.
Dispersed oil and suspended solids accumulate on the surface of the liquid, where they are removed.
The cylindrical profile delivers a very important advantage over conventional designs. The shape ensures a smooth flow path for the gas bubbles into the water, unlike conventional rectangular tanks, where eddy currents can develop leading to poor performance.
NATCO’s Horizontal Hydraulic IGF is designed to meet stringent discharge levels and allow highly efficient removal of insolubles and solids, while preventing emissions of VOCs and other explosive gases.
NATCO’s Horizontal Hydraulic IGF units remove both free oil and dispersed oil. They are effective in treating industrial waste water effluents from production sites, refineries, petrochemical, chemical, and natural gas processing plants, removing 95 — 98% of all free or dispersed hydrocarbon 3 — 5 μm and larger.
