New ISTC Publication: Softener Feed Water Reduction

Download the document.

 

Abstract: Founded in 1915, Carus Corporation is an environmental services company located in LaSalle, Illinois that manufactures a range of products for municipal and industrial markets. The site currently uses approximately 1,360 gallons of water per minute daily. This is equivalent to 1,958,400 gallons per day or 675 million gallons per year, based on 345 days of operation. In 2014, they were charged $0.798 per 100 cubic feet of water used, including the city′s 5% utility tax. In 2015, the company began a new water contract with the city that increased their water usage rate to $1.145 per 100 cubic feet. If they continue to use water at their 2014 rate, they would spend $1,033,725, which as an increase of $312,962. Their goal was to develop a plan to reduce current water usage by utilizing spent non−contact cooling water from their crystallizer hot well to feed their water softeners in the boiler house. Previously,they had used raw city water to feed the softeners, which consume approximately 100 gallons of water per minute. Factoring in the increased cost of the new contract, they saved $86,600 to $120,200 per year and reduced their water usage by 56.6. to 65.6 million gallons.

Locating sustainability information using ISTC’s LibGuides

LibGuides is a web 2.0 platform that librarians use to create topical guides to help their users find information. It combines the best features of social networks, wikis, and blogs into one package. Librarians can incorporate RSS feeds, video, web links, bibliographic citations, search boxes, and other finding aids.

 

LibGuides also allow librarians to create polls and allows users to comment on specific resources and tools within each guide. Users can also sign up to receive e-mail alerts when new content is published, either for particular topics/keywords or for a specific librarian. The guides created by ISTC’s Sustainability Information Curator are available here.

 

Some guides of particular interest include:

 

 

New ISTC Research Report: Advanced Separation Systems for Adsorption and Filtration of Environmental Contaminants

Download the document.

As regulations governing environmental water pollution are enacted, the demand for improved remediation technologies and related materials must be addressed. Some of the most problematic pollutants are the volatile organic contaminants (VOCs) because of their high mobility through soils and into aquifers, and their resistance to biodegradation. Some of the most ubiquitous of these chemicals include trichloroethylene (TCE), chloroform, and methyl tert-butyl ether (MTBE) due to their prolific use in the metals finishing, dry-cleaning, water treatment and reformulated gasoline industries.

In the present study, activated carbon fiber assemblies (ACFAs) were developed and tailored to adsorb these contaminants and improve upon the current industry standard of activated carbon granules (ACGs) while remaining cost competitive. These new materials have higher surface areas, faster adsorption rates due to improved contact efficiencies, and in situ regeneration capability through electrical resistance heating when compared with ACGs.

Advantage is taken of flexible fabrication techniques to tailor porosity and surface chemistry for the specific removal of TCE, chloroform and MTBE from water. The surface area, microporosity, and surface chemistry of ACFA coatings were monitored through the use of TGA, BET N2 adsorption, elemental analysis, and XPS equipment while aqueous VOC concentrations were analyzed using a purge & trap GC. Static and dynamic adsorption evaluations displayed a major improvement over ACGs and the contaminated ACFAs also demonstrated the ability to be regenerated under relatively mild conditions.

Study Finds Biomass Gasification Ash Is Right Stuff for Strong, Light Masonry

BGAbrickAsh produced from biofuel production by biomass gasification is suitable for use in bricks and concrete and lowers costs, according to a recent technical report published by ISTC.

 

Biomass converted to biofuels grew 500 percent in the U.S. between 2002 and 2013. Biomass gasification ash (BGA) from the conversion process costs $80 a ton to landfill and ash amounts will continue to increase when the U.S. Environmental Protection Agency stabilizes agricultural markets with strong Renewable Volume Obligations under the Renewable Fuel Standard. So it is beneficial to explore utilizing BGA for useful products instead of landfilling.

 

Coal ash has long been effectively used as a raw material in brick and concrete production. High unburned carbon in ash adds to the firing energy of bricks in a kiln. Coal ash also has high lime content which gives it self-cementing properties that can substitute for some cement in concrete production.

 

Researchers at ISTC, a unit of the Prairie Research Institute at the University of Illinois at Urbana-Champaign, and Eastern Illinois University (EIU) found BGA shares these traits, allowing cheaper manufacture of standardized quality masonry products using the waste BGA.

 

For brick making, 5-18 percent BGA replaced clay and shale. The best results were seen with ash replacement of 5-10 percent. In this range, bricks were lighter in color and weight, but still met ASTM standards for compression strength of several grades of bricks.

 

Concrete mixes replacing 10-20 percent of Portland cement with BGA showed minimum compressive strength typical of 3,000 psi grades. The work was conducted at ISTC labs by Vinod Patel, B.K. Sharma and Wei Zhang and at EIU labs by Peter Ping Liu and Mori Toosi. The BGA was supplied from EIU’s Renewable Energy Center.

 

“This offers the potential for renewable biofuel production becoming a sustainable energy source if the byproducts can be beneficially utilized avoiding costly landfills,” said Patel, a manufacturing engineer at ISTC’s Oak Brook office.

 

As per an economic analysis considering materials and transportation, a cement company replacing 20 percent of the 6,675 tons of cement it uses annually with BGA would save nearly $155,000. The ash producer would save an additional $107,000 by avoiding landfill fees.

 

“That is in addition to energy savings of 1,906 MMBTUs and reduced CO2 emissions of 1,336 tons,” explained Toosi, a Professor at the School of Technology at EIU.

 

In a case study for a brick producer making 120 million bricks annually, 10 percent BGA use could cut production costs by $153,000. BGA suppliers could save $2.4 million by avoiding landfilling fees.

 

Experimental data also suggested that ash of small particles (0.150 mm and 0.075 mm) might increase concrete strength above 4,500 psi, even at 20 percent addition of BGA.

ISTC publishes Billion Gallon Water Challenge updates

As population increases, the demand for clean, fresh water will also rise, making existing supplies a very precious resource in Illinois and other parts of the US. ISTC seeks to help businesses, industries, communities, and the general public with water conservation measures such as:

  • Using water more efficiently
  • Reuse of water
  • Finding new ways to keep our water resources as clean as possible

ISTC has set a goal of conserving one billion gallons of water in Illinois. It is funding projects and conducting its own research along with other scientists, industry and other experts that will be looking for:

  • Improved treatment of wastewater
  • Reuse of process water in factories
  • Novel recycling methods
  • Other significant water-saving measures

To date, there have been three case studies published as a result of these efforts. They are:

An Updated Look at PCBs in Illinois Published by University of Illinois Prairie Research Institute

The Prairie Research Institute has published An Updated Look at PCBs, a report stemming from the Sept. 17 scientific workshop on “PCBs and Their Impact in Illinois”.  The one-day workshop on the University of Illinois Chicago campus gathered leading authorities on the history and science about the persistent pollutant.

 

PCBs (polychlorinated biphenyls) are a class of synthetic chemicals widely used in industry as a coolant and electrical insulator. The report, videos of panel presentations, and other useful information are available for viewing on the PCB workshop website.
