HEAVY METALS WASTEWATER REMEDIATION
This technology was developed by Ural Process Engineering Company (UPEC)
for remediation of industrial wastewater from heavy metals. A proprietary process of AC current coagulation (US Patent No.6,077,416)
is used to effectively remove and recover heavy metals from industrial wastewater. One of immediate applications is in chromium
removal from wastewater effluent of tanning facilities and electroplating shops. In a partnership with the Brookhaven National
Laboratory, a validation of the technology was completed, funded by the U.S. Department of Energy grant. A prototype industrial
unit was placed in one of tanning facilities in the United States. Other heavy metals removal, such as arsenic, copper, cadmium,
zinc, etc. is possible with minor modifications to UPEC equipment. Ural Process Engineering Company is our partner on this
We are looking to partner with water treatment equipment manufacturer or an engineering firm in the US
or in Europe for commercialization of this technology.

New Technology for Tannery Wastewater Treatment

Heavy metals in certain
industrial wastewaters are a constant problem. Current methods used to treat industrial effluents are relatively cumbersome
and expensive. As a rule, when metals such as chromium, arsenic, copper, etc. are involved, the dewatered sludge has to be
deposited into a landfill at a substantial cost to the industry.
In the tanning and leather finishing industry, chromium
contamination is of particular concern. An average tannery may expend a considerable amount of resources for wastewater treatment.
Additional costs involve disposal of other chromium contaminated solid waste, such as leather shavings and trim. Development
of a successful technology to treat the tannery wastewater combined with effective solid waste disposal may provide the tanning
industry in the US and other countries with the needed boost they need to stay in business and continue to operate profitably.
basic concept for the treatment technology is in utilization of an electrocoagulation process originally invented by UPEC
(Ural Process Engineering Company) in Russia. In this process substantial improvement of heavy metals extraction from wastewater
is accomplished by applying AC pulsed current to electrodes of a special design. Electrode materials are usually made of scrap
aluminum and/or duralumin and steel (iron). The rate of decontamination is a factor of 5 to 10 better then with other coagulation
methods. The method is effective not only for removal of heavy metals, such as Co, Cr, Cu, Zn, Cd, As but it is also effective
in removal of organic pollutants. The method is covered by a US patent with another application recently submitted to the
US Patent Office.
were undertaken jointly by UPEC and Fenix Technology to determine applicability of the UPEC electrocoagulation process for
tannery wastewater treatment. The work was performed at the Irving Tanning Company in Hartland, Maine in cooperation with
the Brookhaven National Laboratory (this work was partially funded by the US Department of Energy). In addition, a similar
technology was already implemented by UPEC in Russia for treatment of wastewater at a copper electroplating facility, where
the copper content in wastewater was successfully reduced to levels below 0.1 ppm. Earlier, UPEC developed a similar process
for copper removal from a major copper smelter in Russia.
Many tanneries are currently utilizing local municipal wastewater
plants to treat their effluent and then to deposit the resulting sludge into landfills at a considerable cost. An average
tannery may spend approximately $10 to $15 per 1,000 gallons for treatment of discharged wastewater and waste disposal.
Further, the tannery will have to dispose of other chrome bearing solid wastes (leather shavings and trimmings). This comprises
a substantial cost component of the operations for many tanneries. Considering that the tanneries in the United States are
running at a very slim profit margin, the environmental cost could often be the last straw in making the tannery profitable
or to break-even. Reducing this cost to about $7-8 per $1,000 gallons would significantly improve their balance sheets
and provide additional incentive to keep the operation in the United States (many companies are opting to close their plants
and move them offshore).
Currently, there is no other practical alternative for the solid waste disposal other than
the landfill. The costs of landfill are increasing globally and, in particular, constraints regarding chrome content in many
countries render this waste as special incurring higher disposal costs. The success of UPEC wastewater treatment
technology is highly dependent on effective removal of chromium compounds and organic contaminants from wastewater an on utilizing
filtered solids removed from the wastewater and processing them in a way that would eliminate the need for the costly landfill
disposal. This is the second component of this technology that is currently under development.

Wastewater Electrocoagulation Industrial Prototype
Technology for production and application of sodium ferrates
UPEC in collaboration
with FENIXTEC and funding from the US Department of Energy (2006-2008) has developed cost effective technology for producing
industrial quantities of materials in the family of sodium/potassium ferrates that are effective in reducing heavy metals,
specifically arsenic, from drinking water and industrial wastewater, as well as in removing other contaminants and for sanitizing
wastewater and drinking water. Ferrates are the most
potent oxidizing agents known. We perfected the manufacturing process and designed equipment to produce it in industrial qunatities
as well as developed a technology that allows to make a more stable product.
This material can be added
in relativley small quantities (from 1 to 100 mcg/l) to water or wastewater and it works within seconds removing heavy metals,
phosphates and sanitizing from various forms of bio-contaminants. Ferrates could replace chlorines as disinfecting
agent for tap water without any side effects of chlorine. In recent tests addition of FernelTM would
effectively reduce E-coli forms from 106 to under 100 level in seconds.
material developed is trademarked as FernelTM and is covered by US and Russian patents. We have finalized the equipment
design for production of FernelTM and are currently negotiating strategic partnerships for introducing FernelTM
technology worldwide. UPEC is currently producing commerical quantities of Fernel for various applications. Samples
of FernelTM are available for testing.
