SASOLBURG. – Sasol and General Electric (GE: NYSE)’s GE Power and Water have together developed new water technology that will clean waste water, while also providing biogas as a by-product for power generation. This new technology, known as Anaerobic Membrane Bioreactor technology (AnMBR), will be further developed at a new demonstration plant at Sasol’s R&D Campus at its Sasol One Site in Sasolburg.

“This is another exciting technological innovation that will further entrench our position as a world-leader in gas-to-liquids (GTL) technology and synthetic fuels production. While sophisticated water treatment technologies are already employed at Sasol’s major operations, this particular development will enhance our efficiency even further,” said Ernst Obersholster, Sasol Group Executive for International Energy, New Business Development and Technology.

“GE is excited to be partnering with Sasol on this initiative that further outlines our commitment to supporting the sustainable development of South Africa with advanced infrastructure technologies, services and solutions. This partnership demonstrates what the private sector can achieve by working together for the benefit of growing the economy and making the economy competitive,” said Tim Schweikert President and CEO for GE South Africa.

AnMBR involves anaerobic micro-organisms that can live in environments devoid of oxygen, such as sediment layers on floors of lakes, dams and the ocean. These organisms are almost ubiquitous –  found in the human digestive system, under the earth’s surface, deserts and mountain peaks, to name a few. Sasol currently uses aerobic microbes to treat GTL and coal-to-liquid (CTL) effluents in ORYX GTL, Qatar and Synfuels, Secunda facilities.

One of the by-products from the Fischer-Tropsch (FT) process is an effluent stream rich in organic acids and alcohols. Traditional (aerobic) treatment technologies treat this effluent by converting the organics to carbon dioxide. The benefit of the AnMBR is that the micro-organisms convert these organics into a methane rich bio-gas which can then be used for power generation. This then results in an overall efficiency improvement in the GTL process. By converting the effluents to a valuable product (power) there is a resulting improvement in the GTL value proposition. Another benefit of the AnMBR is that it produces almost 80% less waste biosolids than the previous generation process. The treatment of GTL-derived effluents is complex and challenging. Sasol pioneered the treatment of effluents from the GTL process in Ras Laffan, Qatar, where effluents are treated and recycled for use as irrigation water in the city of Ras Laffan. Sasol’s second generation offering, which is currently being designed for the US GTL facility, is the aerobic Membrane Bioreactor (MBR). The AnMBR helps maintain Sasol’s leadership position in this field by converting wastes into value-adding products. Micro-organisms break down complex organics, such as proteins and carbohydrates, through a process called hydrolysis, to simpler building blocks, such as sugars that provide food for the micro-organisms. The waste produced is bio-gas, which can be used as feedstock to generate power.

“The organics in wastewater generated from our operations have proven to be the ideal food, or substrate, for Anaerobic micro-organisms,” said Thulani Dlamini, Executive Manager Research and Development at Sasol Technology. “We will now continue to explore and develop this technology further with the potential for commercial application to our future GTL facilities.”

Sasol has been developing the technology for a number of years with promising results. The partnership with GE is aimed at leveraging GE’s ecomagination-qualified ZeeWeed 500 membrane and decades of membrane bioreactor experience, and Sasol’s expertise in biological treatment of FT derived effluents. “The new AnMBR is one of the many solutions that can be developed in the Petrochemical and Refining environment to benefit all other industries” says Daniele Scenarelli, GE Account Executive for Sasol. “This strategic partnership, which was signed in 2010, symbolises a new way of doing business between customers and suppliers. It is a collaborative approach and a mutual commitment to technology development and innovation aimed to accelerate the commercialisation of this new technology.” Bench scale test work has been on-going for the past year with promising results and with the construction of a pilot plant at Sasol’s R&D facilities this improves the potential for commercialisation of this technology.

It is anticipated that the technology will be commercially ready early in 2015. Sasol will have exclusive rights to apply this technology to FT-based plants whilst GE will have the right to market the technology for other industrial uses.

This Boeing 737 is a landmark in Midvaal and can be seen when travelling on the R59.

It’s a marketing strategy to attract clients by using the remains of an old Boeing 737 – complete with cockpit.

Motorists travelling on the R59 at night say they cannot miss the lights inside the cockpit and on the side of the plane – giving them the impression that a plane has just landed there.

Sheldon Mandy, director of the company, said this is just the beginning of great things to come. “We want to make the area look like a first class, five-star business,” he says.

Motorists will have to wait to see the beauty of the buildings once they are finished with the construction in December. Sheldon said he got the idea from his father, Neville Mandy founder of ‘Natures’s Choice’ that started in Heidelberg in 1987.

For a long term project, said Mandy, they want to invite learners from local schools to enjoy lunch in the plane.

“When you sit inside the plane, you can feel the vibration of the engines mounted on the wings.

“The seats inside the plane were changed and a table brought in to make it look like a boardroom.

“We bought the complete Boieng 737 from the airport. It took hours transporting the Boeing to our facility. The green and red lights have been donated by a local electric company,” concludes Mandy.

Nature’s Choice is presently Africa’s largest and South Africa’s leading health food distributor, with over 500 outlets and stockists throughout the country, Africa, and a growing number of trading partners overseas.

VANDERBIJLPARK. – ’n Waterwolk se sproei wat op hulle gesigte neerreën, is iets waaraan Shanté Bukes se teenstanders maar aan gewoond sal moet raak.

Wanneer sy op haar waterponie klim, verander dié beeldskone blondine van Vanderbijlpark in ’n vuurvreter-mededinger… Dit het die wêreld se bestes onlangs in Amerika, Arizona op Lake Havasu City op ’n harde manier geleer toe sy as wêrelkampioen tydens die IJSBA Jet Ski World Finals gekroon is.

Sy het in twee klasse: amateur runabout stock en women’s runabout stock deelgeneem. Sy is in laasgenoemde afdeling as die wêreldkampioen aangewys.

In ’n waterponiewedren is spoed nie alles nie, vernuf en jakkalsstreke is die giftigste pyle in jou koker. Vra maar vir Shanté se teenstanders wat geen teenvoeter vir haar wêreldklas loopgraaftegniek om voor te kom en voor te bly, gehad het nie.

Die oud-leerling aan die Hoërskool Transvalia en tans eerstejaars B.Com.-student aan die NWU is uitgeslape op die water.

In die tweede ronde van die wedren het haar teenstanders kragte saamgespan om haar hok te slaan, maar daar het weer dadels van gekom.

“Ek skoei my lewe op Filipense 4:13: “Ek is tot alles in staat deur Hom wat my die krag gee,” sê Shanté. As ’n selferkende adrenalien verslaafde het sy in 2010 aan waterponie-wedrenne begin deelneem. Vele mans is in dié proses rooigesig gelaat. Sy het Suid-Afrika al twee keer in Thailand by die Kings World Cup verteenwoordig en haar nuwe wêreldkroon gaan nogal mooi by haar Protea-kleure pas.

Vaalweekblad het in 2010 die eerste keer oor haar berig toe sy tweede tydens die gewilde Ice Block-wedren geëindig het en in die proses ’n voormalige wêreldkampioen laat bloos het.

“Ek floreer as daar adrenalien betrokke is,” het sy destyds te kenne gegee.

Volgens haar ouers kom haar liefde vir spoed en avontuur al van kindsbeen af. “Sy het natuurlike aanvoeling en talent vir die sport. Sy het sommer die tweede wedren waaraan sy deelgeneem het gewen,” het haar pa, Johan, gespog.

Wanneer sy nie op die water is nie, is sy besig om haar vlieglisensie te verwerf.

Wat haar onmiddellike toekomsplanne betref, gaan sy in Desember in Thailand wéér aan die Kings World Cup deelneem. Die deelnemers daar moet maar solank hulle lywe vet smeer en uitkyk vir die waterponie waarop nr.72 pryk.

We have all heard the saying so many times before: An apple a day keeps the doctor away. And with good reason as apples are beneficial in maintaining your health.

The phytonutrients in apples can help you regulate your blood sugar. In addition, the polyphenols in apples have been shown to lessen absorption of glucose from the digestive tract; to stimulate the beta cells of the pancreas to secrete insulin; and to increase uptake of glucose from the blood via stimulation of insulin receptors. All of these mechanisms triggered by apple polyphenols can make it easier for you to regulate your blood sugar.

The whole food form of apples is also important if you want full satisfaction from eating them. Researchers have recently compared intake of whole apples to intake of applesauce and apple juice, only to discover that people report less hunger (and better satiety, or food satisfaction) after eating whole apples than after eating applesauce or drinking apple juice. But especially interesting was an additional finding about calorie intake following apple consumption.

When healthy adults consumed one medium-sized apple approximately 15 minutes before a meal, their caloric intake at that meal decreased by an average of 15%. Since meals in this study averaged 1,240 calories, a reduction of 15% meant a reduction of 186 calories, or about 60 more calories than contained in a medium apple.

For these researchers, “getting ahead” in calories with a net reduction of 60 calories was a welcomed outcome of the study, and an extra benefit to their study’s primary conclusion -the importance of whole apples (versus other more processed apple forms) in helping us manage our hunger and feeling more satisfied with our food.

Scientists have recently shown that important health benefits of apples may stem from their impact on bacteria in the digestive tract.

In studies on laboratory animals, intake of apples is now known to significantly alter amounts of two bacteria (Clostridiales and Bacteriodes) in the large intestine.

As a result of these bacterial changes, metabolism in the large intestine is also changed, and many of these changes appear to provide health benefits. Several anti-cancer studies show daily intake of this fruit to provide better anti-cancer benefits than lesser amounts. So there may be some truth to that old phrase.

It is recommended that everyone eat at least 2-3 whole fresh fruits per day, or the equivalent of 2-3 cups’ worth of fresh fruit.

Within this framework, if apples are a type of fruit that you strongly prefer, there would be nothing wrong with consuming one on a daily basis, and you may get some special health benefits by doing so.
