Compliance with Duraflow
The Duraflow microfiltration module is the lynchpin of a total wastewater treatment system that meets today's dual priorities of high compliance at high throughput.

In this example, wastewater is collected in the wastewater feed and equalization tank (1). It is pumped at a set flow to each of two reaction tanks (2) in series where Duraflow precipitants and coagulants are fed to precipitate the contaminants into particles. The water then flows by gravity to the concentration tank (3), which is the feed tank for the microfiltration system (4).

During filtration, back-pressure forces some of the water through the microfiltration modules' membranes as solids are swept along back to the concentration tank (3). The water that passes through the membranes is collected via the outer shells of the modules and flows to the final neutralization tank (5) for pH adjustment and discharge or flows to an RO for recyling.

As solids accumulate and concentrate in the concentration tank they must be wasted periodically either directly to a filter press or to a sludge holding and thickening tank and then to a filter press (6).
