Hoffland Environmental, Inc. (HEI), an employee owned company,
was founded in 1978 with the purpose of providing the design
and installation of wastewater treatment equipment to the
metal finishing industry. The need for a competent, reliable
contractor was apparent due to the demand of the new emerging
governmental environmental regulations within that industry.
HEI has successfully developed a library of knowledge on
the economical treatment of toxic
heavy metals, oil & grease, toxic hydrocarbons,
suspended solids,
and animal waste.

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
SCADA
systems 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., Master lock, 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,
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. Hoffland Environmental,
Inc. has the ability to post treasury rated performance
bonds, provided by independent insurance agencies, for all
major projects. Hoffland Environmental, Inc., with its Professional,
Chemical, Environmental, Mechanical, and Electrical Engineers,
has been designing ground water, industrial wastewater,
and remediation projects for over twenty-five years.
HEI provides innovative and economical solutions to the
treatment of heavy metal waste containing lead, arsenic,
mercury, copper, nickel, chromium, or zinc. Cyanide, phenol
and chromate wastes are economically treated to regulatory
limits. Many times the metals are removed to less than detectable
levels. Suspended solids are readily removed, concentrated
and compacted to transportable solids. The hazardous waste
may be economically dried further to reduce the disposal
cost.
HEI manufactures its patented (US Patent No. 4747691 and
4952066) Polymixer
to dilute, rapidly mix, and in-line age the polyelectrolyte
providing a fully activated polymer. Since the polyelectrolyte
is fully activated, less polymer is required and the unit
provides a positive pay back in less than one year.
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. HEI has been granted US Patent No. 6054044 for
this unique process.
For the large CAFO (OVER 1000 ANIMAL UNITS) Ph is more
economical to concentrate and digest the solids with mesophilic
anaerobic bacterial cultures. The methane by-product is
used to produce electricity for sale and heat the rector
to sustain the mesophilic microbes. The treated anaerobic
digester effluent is furth4er processed under aerobic conditions
to remove the remaining BOD and nitrify/denitrify the nitrogen
containing compounds. This technology provide a net positive
return on the capital invested in the wastewater treatment
equipment.
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
- Electrodepositos, S.A. DE C.V., Naucalpan, Edo.
- Tubos De Acero De
Mexico, Veracruz
- Recubrimientos Metalicas, Col. Aragon
- Mexinox, S.A. DE C.V., San Luis Potosi
- Chrysler, Mexico City, Mexico
As the new millennium commences, HEI has expanded to mainland
China by opening a sales and engineering office in Beijing.
HEI has supplied several wastewater treatment facilities to
China's metal finishing and petrochemical industries. The
new office will provide engineering, start-up supervision,
and service to our existing customers and supply a more responsive
service for our future customers.
Licensed manufacturers operate in Brazil, Argentina, Chile,
Singapore, and Taiwan.
HEI designs, engineers, manufactures, and installs complete
industrial wastewater treatment facilities. A complete system
may include the following sub systems:
HEI systems are in operation in these industries:
Aerobic
Biological Oxidation
