Direct Contact“Concentrator”
• Feed water interior to tube bundles.
• Heat transfers across tube bundles.
• Tube bundles prone to fouling, rapid corrosion.
• Requires considerable high-alloy metals.
• Requires considerable pre-treatment and highly experienced water operators
• Requires a crystallizer to achieve ZLD
• No heat exchange surfaces or membranes to foul; low-cost materials.
• Direct use of waste heat (exhaust gases).
• Patented Gas-Liquid Section creates acres of surface area for rapid evaporation.
• Require little-to-no pre-treatment and anyone can be trained to operate
• Can deliver ZLD in a single unit operation … no crystallizer required

Heartland Concentrator™ Process FlowThe Heartland Concentrator™ is a rugged and cost-effective solution that can concentrate the widest range of challenging wastewaters all the way to zero liquid discharge (ZLD) in one-unit operation.
The Heartland Concentrator is a ‘direct-contact evaporator’ –where hot gases are mixed directly with feedwaters in Heartland’s proprietary Low-Momentum, High-Turbulence (LM-HT) process.
With only 2 moving parts, no heat exchangers or membranes to foul, low-cost materials of construction, little-to-no pre-treatment required, and ease of operation, Heartland can deliver zero liquid discharge (ZLD) in a single unit operation – with no crystallizer required.
