HEI operates its own engineering and manufacturing facility in Conroe, Texas. The engineering offices incorporate the latest computer aided design equipment. The manufacturing facility includes steel fabrication to 20 tons with a maximum height of 32 feet, and complete sandblasting and coating equipment. A machine shop is maintained for the smaller sophisticated components. A complete electrical assembly area is utilized to manufacture both conventional systems and computerized modules with CRT displays. |
Adequate area is available to assemble and test skid mounted systems. A bench scale laboratory test facility is provided to custom design equipment to meet the customer’s specifications. Modem access computers are utilized to monitor and reprogram SCADA systems.
From the first clarifier sold in 1978 to present, where HEI has completed a turn-key project requiring over 125 major pieces of environmental remediation equipment, HEI still operates under its original directive ... "We shall design, build and install each piece of equipment as if we were going to use it ourselves." With its in-depth process knowledge of wastewater treatment engineering, in-house manufacturing and project management background, the company has a significant competitive advantage in bidding complete environmental equipment packages and turn-key plants. |
|
The company has the capabilities to assume total process responsibility, feasibility studies, design engineering, fabrication, installation, and start-up of environmental projects requiring any or all of the above major functions. There are over 500 projects completed for such major corporations as Hughes Tool Co., E-Systems, American Airlines, TWA, Douglas Aircraft, Burlington Industries, Shell Oil, Caterpillar, Ford Motor Co., General Motors, General Electric, Nissan, Outboard Marine Corp., Masterlock, Fairchild, Lockheed, Phillips, U.S. Corp of Engineers, U.S. DOE, U.S. Army, U.S. Navy, and FAA.
|
In addition to the U.S., the company has supplied equipment to Argentina, Mexico, Canada, Sweden, China, Taiwan, Philippines, Egypt, Germany, India, Hong Kong, Puerto Rico, United Kingdom, Turkey, Iran, Venezuela, Indonesia, Singapore, Ukraine, Israel, Brazil, Belarus, and Russia. |
Remediation equipment is manufactured as individual pieces of hardware or may be skid-mounted preassembled units with interconnecting plumbing and electrical wiring completing the factory assembled system.
To date, the largest contracted turn-key project was valued
at $33 million. |

One of the main themes at HEI keys upon process needs for resource recovery equipment. Our Alert 2000, is such an item used to recover valuable metals. The zero discharge system provides reuse of purified water with zero liquid discharge.
Zero discharge equipment utilizes conventional precipitation, followed by membrane separation equipment to produce a reusable high quality water. The customer may reuse the treated water directly back in their process line. The waste dissolved salts is evaporated to highly concentrated brine for disposal or solidification. The precipitated and compacted solids are dried to further reduce the volume of waste.
HEI developed the use of double pass reverse osmosis systems producing 2 - 3 micro siemen purity water for NOx abatement in gas fired turbines. The high purity water is produced without employing mixed bed de-ionization equipment, the use of chemicals, or generation of waste chemicals.

Hoffland Environmental pioneered the treatment of waste from CAFO's (Concentrated Animal Feeding Operations) by economically removing the waste solids and biologically treating the remaining liquids. Nitrification/denitrification microbial cultures are utilized to remove the high levels of nitrogen. The treated water, free of nutrients nitrogen and phosphorus, may be utilized for irrigation without over-nitrifying the soil. In 1994, HEI established an engineering and sales office in Minsk, Belarus operating as AETE (American Ecological Technologies and Equipment) to serve the industries through the CIS (former USSR). Turn-key facilities have been installed for:

HEI holds all required licenses in Russia to import, manufacture, and install wastewater treatment equipment.
In 1990, HEI established a strategic partnership with ACS Medio Ambiente, Mexico City to provide industrial wastewater treatment equipment for Mexico and Central America. ACS maintains a facility for engineering, sales, manufacturing and installation of HEI’s standard equipment. Major projects have been completed for:
- Nissan, Mexico City Mexico
- Chrysler, Mexico City Mexico
- Tubos De Acero De Mexico, Veracruz
- Recubrimientos Metalicas, Col. Aragon
- Mexinox, S.A. DE C.V.,San Luis Potosi
- Electrodepositos, S.A. DE C.V., Naucalpan, Edo.
Licensed manufacturers operate in Brazil, Argentina, Chile, Singapore, and Taiwan.
