Heartland Water Technology

Heartland uses mechanical vapor recompression thermal evaporation to treat high-salinity industrial wastewater. The process evaporates water and crystallizes dissolved solids, producing distilled water and dry salts — achieving zero-liquid discharge without chemical pretreatment. The technology is designed to handle feedwater that would foul or clog membrane-based systems.

Heartland targets industrial sectors with challenging wastewater streams: power generation (coal and natural gas flue-gas desulfurization blowdown), oil and gas (produced water from hydraulic fracturing), mining (mine water and tailings), and industrial manufacturing (chemical and pharmaceutical process water). The common thread is high salinity, variable flow, and tightening discharge regulations.

Heartland is an industrial technology company that designs, builds, and sells water treatment equipment, not an investment firm. It does not manage third-party capital, make financial investments, or operate as a family office or asset manager. Its revenue comes from equipment sales, installation, and service contracts — not from deploying an investment pool.

Heartland's thermal evaporation systems can handle higher total dissolved solids (up to saturation) than reverse osmosis, which typically tops out at 70,000–80,000 ppm TDS. The thermal approach also handles variable feedwater quality and high silica or hardness levels that would scale membranes. However, thermal systems consume more energy per gallon treated, making them best suited for high-salinity streams where RO is not viable.

Zero-liquid discharge (ZLD) means all wastewater is treated on-site so no liquid effluent leaves the facility. Regulators in the US (EPA Steam Electric Effluent Guidelines), China, and parts of Europe are tightening discharge limits for mercury, selenium, and total dissolved solids, pushing power plants and industrial facilities toward ZLD. Heartland's systems provide a path to compliance while recovering water for reuse and producing dry solids for landfill or potential resource recovery.
