Variable Depth Biological Treatment

ATLANTA, Sept. 27 /PRNewswire-FirstCall/ -- Perma-Fix Environmental Services, Inc. today announced that it has completed the construction of its new Bio-Fix process at its Ohio waste treatment facility, and that the facility has begun accepting commercial wastewater for treatment through this process.

The Bio-Fix process is a new technology developed by Perma-Fix that incorporates its patented variable depth biological treatment process with several proprietary water treatment processes to treat, highly organic, contaminated wastewaters, to remove the organic constituents. The process was developed to combine the advantages of physical and chemical treatment with the cost and efficiency advantages of biological systems.

Dr. Louis F. Centofanti, Chairman and Chief Executive Officer, stated that, "The industrial wastewater market is a multi-billion dollar market in the U.S. and our new Bio-Fix process is focused on the more heavily contaminated wastewater streams in this market, such as waste oils, phenols and "lean" waters. The new technology enables Perma-Fix to treat these difficult waste streams at much more competitive prices than traditional methods.

"The new process meets the EPA's new centralized treatment standards that go into effect in 2003. These tightened standards may impact the ability of certain competing treatment facilities to treat such waste streams."

Perma-Fix Environmental Services, Inc. is a national environmental services company, providing unique mixed waste and industrial waste management services. The Company has increased its focus on the nuclear services segment, which provides radioactive and mixed waste treatment services to hospitals, research laboratories and institutions, numerous federal agencies including the Departments of Energy and Defense and nuclear utilities. The industrial services segment provides hazardous and non-hazardous waste treatment services for a diverse group of customers including Fortune 500 companies, numerous federal, state and local agencies and thousands of smaller clients. The Company operates nine major waste treatment facilities across the country.

Gypsum Byproduct Used

CHARLOTTE, N.C. -- National Gypsum Company's Shippingport, Pa., wallboard plant has won the 2002 Governor's Award for Environmental Excellence. The award was presented at a special ceremony this morning at the Capitol in Harrisburg, Pa. National Gypsum is one of the world's largest producers of gypsum wallboard.

The Shippingport Plant uses byproduct gypsum from nearby First Energy's Bruce Mansfield Plant to manufacture wallboard. The byproduct gypsum is produced as the power plant scrubs its high-sulfur coal emissions.

Traditionally, the wallboard production process starts by crushing gypsum rock, heating it to remove moisture, and then adding water to form a stucco slurry. The stucco is sandwiched between two layers of paper and dried in a kiln, producing a durable wall panel with fire-resistant properties.

Instead of using gypsum rock, the Shippingport operates around the clock and uses 100 percent byproduct gypsum at a rate of 70-80 tons per hour. This material formerly was disposed of in First Energy's Little Blue Run landfill. The byproduct gypsum is transferred from the power plant to the wallboard plant by a 1.5-mile conveyor system.

As in other National Gypsum plants, the Shippingport operation recycles in several other areas as well. Waste wallboard goes back into the system, and trimmings from paper rolls are sent to the company's paper product plants for recycling. And, National Gypsum produces its wallboard facing papers from recycled paper at its four paper mills.

Process wastewater is recycled, resulting in zero discharge. All storm water generated at the Shippingport site is treated in sedimentation ponds prior to discharge. Dust collected in the facility's baghouse system is recycled into the process. The state-of-the-art baghouses are designed for particulate removal efficiency greater than 99.9%. Parts washing solvents used in maintenance activities, waste oils, spent vehicle batteries, and scrap metal are sent to third-part recyclers.

Headquartered in Charlotte, N.C., the company has a network of 31 plants in North America and employs approximately 2,700 employees.

The Largest in W. Hemisphere

Watertown, MA - The largest seawater reverse osmosis (SWRO) desalination plant in the Western Hemisphere has successfully started up in the first quarter of 2002 on the Caribbean island of Trinidad. The 109,000 cubic meter per day (29 million gallon per day) desalination plant is providing the Water and Sewerage Authority of Trinidad and Tobago (WASA) and the industries of the Point Lisas Industrial Estate with a guaranteed, high quality water supply.

With desalinated water now able to meet the region's burgeoning industrial requirements, WASA is able to provide fresh potable drinking water to its residential users. Recent reports had indicated that 23% of the island's population had received a water supply for 2 or fewer days per week and only 32% of the population had received water for 5-7 days per week.

Construction on the desalination plant began in 2001 as part of a joint venture between Ionics and its local partner, Hafeez Karamath Engineering Services Ltd. The plant is owned and operated by the Desalination Company of Trinidad and Tobago (Desalcott). Ionics served as the turnkey Engineering, Procurement and Construction (EPC) contractor to Desalcott. The joint venture company will provide water to WASA under a 23-year build-own-operate contract. The facility was built with funds from the owners' capital, bridge loan financing from Republic Finance and Merchant Bank Limited of Trinidad, as well as loan proceeds from Ionics.

According to data in the International Desalination Association's 2000 Worldwide Desalting Plant's Inventory Report, Ionics is the leading supplier of membrane-based desalination systems in the world. Ionics has built more desalting plants of a size greater than 100 cubic meters per day than anyone else in the business. Ionics has built, owns and operates numerous desalination plants around the world. In Curacao, for instance, Ionics recently signed a 10-year agreement with Aqualectra to expand the size of its existing seawater RO plant from 10,000 cubic meters per day to over 17,000 cubic meters per day. The 30,000 cubic meter per day desalination facility in Barbados, commissioned in early 2000, is delivering water to 20% of the island's population. This is the largest such brackish water RO plant in the Caribbean.

In addition to its landmark water desalination projects, Ionics is playing a key role in the rapidly growing area of water reuse. In 2001, an international consortium led by Mohammed Abdulmohsin Al-Kharafi & Sons and Ionics won the 27-year, $380 million contract for what will be the largest integrated membrane system in the world for water reuse. The Sulaibiya Wastewater Treatment Project is Kuwait's first wastewater build-own-operate project and will convert over 300,000 cubic meters per day (79 gallons per day) of wastewater into water for agriculture and irrigation.

Ionics, Incorporated is an internationally recognized leader in the treatment and analysis of water and wastewater. Founded in 1948, Ionics has over 50 years of experience in the design, installation, operation and maintenance of membrane-based water treatment systems. Ionics is the leading supplier of membrane-based desalination systems in the world. Ionics is also the world leader in the supply of ultrapure water systems for the microelectronics industry and in the measurement of total organic carbon, a leading water quality indicator.

Help Forum

People post their requests for help and offer their suggestions to others in our open forum.

Mr. Johnson wants a "dry" cake:

I am working on the design of a closed loop wastewater treatment facility for a pulp and paper plant in the United States. The objective is to get off the sewer discharge and reuse as much of the water as possible.

We have solved the water part of it and will be using a membrane system to recover 96% of the volume for reuse in the plant.  We are currently looking at options for the remaining 4% reject.  I am interested in ideas for the most appropriate dryer technology for this purpose.

We would like to make a dry cake with no effluent requiring treatment.  The process parameters are: 15 gpm (3.41 m3/hr), 43*C, 4% Total Solids.

Mr. Rahman needs help with digestion:

Part of my WWTP has anaerobic system. The system is used to reduce the COD level from 30-50K ppm to about 8Kppm of COD.

Recently, from our observation, it seems that the system is not performing as what it should be. The output reduction now is less than 15% compared to last time about 80-85%.  It really is a puzzle. Anyway, can anyone who has experience running the Anaerobic system share their experience or advise the best way to tackle this issue.  Even we control the pH to be about 6.8-7.1

I suspect is that there is a short-circuit in the system, therefore, the bugs are not really in contact with the waste water.

What is the latest technology in the market for the Anaerobic system ?  There was an advised to have a circulation system in the tank. Will this help ?  How frequent we need to reseed the bugs ? 1 year ? 2 year ?
