Gravity Feed Installations

Quarry

Quarry

The drainage water from this stone and sand quarry water contained suspended solids (clay particles) which needed to be removed for the water to be in compliance. The run-off water is channeled through a series of ditches and eventually runs out of a 16" steel pipe. Water flows from the bottom of the pipe through a flexible 2" line into the Wheel Treater. To keep rocks and debris from clogging the line, a screen was attached to the line opening. In this installation, run-off water is discharged intermittently. The Wheel-Treater responds to the discharge by pumping a Chemstream coagulant into the water, which keeps this pond very clear and in compliance.

This mine drainage water contained high levels of dissolved iron. Water flows from the bottom of a drainage pipe through a flexible 2" line into the Wheel Treater. The natural water flow powers the Wheel-Treater to pump AMDTreat 252 into the water. This installation also includes an aeration trough to mix and aerate the water. The addition of AMDTreat 252 combined with the aeration trough significantly reduces dissolved iron, bringing the drainage water into compliance.

Pump Feed Installations

When these lined ponds were constructed, the mine discharge pipe was laid in a position just above the liner. In this example, an elbow and riser pipe were installed in order to flood-feed the Wheel-Treater's intake manifold. Many pump feed installations have been configured in this same way because it's very dependable and reliable. When water is pumped from the mine or pit, it flows to the top of this piping configuration. Water then flood-feeds the Wheel-Treater. A gate valve is used to throttle the water flow so that the Wheel-Treater's pump RPM drives the peristaltic pump at an appropriate speed. This pump speed insures that the correct amount of EverFloc is dispensed.

In this installation, a Wheel-Treater Jr. is used to dispense Chemstream AMDTreat 252, which is an enhanced 25% caustic soda product. The water flow is elevated so that it water can be gravity fed to the Wheel-Treater's intake. This is similar to the elbow and riser but with a more gradual pipe elevation. This mine's drainage is acidic with dissolved metals as well as suspended solids. The pond retention is adequate for AMDTreat to take care of the total treatment objective which is to precipitate iron, manganese, and clarify the water.
