What Customers Say Regarding Leachate Management:“It just keeps coming!”

Trends Impacting Leachate Management- Rising cost of leachate management

- More uncertainty than ever before (regulatory, technical, community)

- More POTW risk than ever before

- Tightening POTW regulation

- Leachate impact on POTW treatment (visibility, strength, ammonia)

- Emerging contaminants of concern

- Continued diligent regulator enforcement

- Less recirculation / more dewatering

- Solid waste characteristics changing impacting leachate quality and volume

- Continued demand for renewable energy and CHP

- Managing in conditions of uncertainty


Concept of Operation: Brine Concentration Methods

Thermal Brine Concentrators

Feed

Heartland Concentrator™

Hot Gases

Feed

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.
