Low Profile Air Strippers

Maple Leaf offers several technologies for stripping VOC's from water and the treatment of off-gas.

For low flow rates EnviroMaster Multi-Stage Aeration units are available which utilize efficient air flows to strip volatiles from water in multiple stages. Manufactured by Maple Leaf and utilizing industry standard Rotron blowers, these treatment units are available as stand alone or as part of a complete remediation package.

For higher flowrates Maple Leaf utilizes low profile air stripper packages built around Carbonair's exclusive STAT series air strippers and Rotron blowers. These units feature rapid installation, easy winterization, easy maintenance and small footprint. With their efficient design, these units minimize air flow while maximizing VOC removal.

In Carbonair's STAT units, the water and air are contacted in step-wise fashion on multiple trays. The water enters at the top and flows across each tray. The air passes upwards through openings in the trays, then bubbles through the water to form "a surface of foam" which provides extreme turbulence and excellent volatilization. Since the water in Carbonair's STAT units flows horizontally across each tray, the travelling path length of water and the required removal efficiency (up to 99.99%) can be achieved by increasing both the number and length of the trays.

Options:
		Off-gas carbon absorption
		Off-gas catalytic oxidation (BTEX and chlorinated VOC's)
		Well pumps and level controls
		Humidity control and winterization
		Control panel with optional off-site monitoring

Vapour Liquid Separator

 The VL series of vapour/liquid separators are constructed of epoxy coated steel with PVC internals for maximum durability at a reasonable cost. The VL series has a wide range of operating flow rates and sizes and can be adapted to many operating conditions.

The VL200 is the most popular model with flowrate capability to 350 cfm. Each VL200 can be equipped with a vacuum relief valve and a positive air shutoff device that closes off airflow through the separator when the water level in the separator reaches a high level. This device does not shut the blower down, however the vacuum relief valve opens to allow inlet air to the blower. A high level switch is available as an option to allow the blower to be shutdown on high level.

Other models are available up to 10,000 cfm.

Options:
		Internal sump pump with level control (non x-proof)
		High level switch (explosion proof)
		Water Treatment System
		Air Treatment Systems

Pricing (VL200)
		Base Unit:
		Vacuum Relief
		Mechanical high water protection:
		Electrical high level switch(x-proof):
