In many industrial sectors, the need to be able to unload solid material, fine grade or in lumps, into lorries or other vehicles with little or no dust, is satisfied by the loading bellows.

Manufacturing programme includes various types of loading bellows used in a range of sectors, such as the cement industry, for lime, gypsum, and premixed plasters steelworks, mining, chemical, power station sectors etc.

CS loading bellows: This equipment is used to load bulk materials, in powder or small lumps, from a silo or installation, onto a generally closed vehicle (lorry or rail wagon);

CSM loading bellows: This equipment is used to load abrasive bulk materials, in small lumps, from a silo or installation, onto a generally open vehicle (lorry or rail wagon) or discharged at a yard;

Hydrogen is a critical component in the manufacture of thousands of common products from plastic to fertilizers, but producing pure hydrogen is expensive and energy intensive. Now, a research team at Princeton University has harnessed sunlight to isolate hydrogen from industrial wastewater.

In a paper published Feb. 19 in the journal Energy & Environmental Science, the researchers reported that their process doubled the currently accepted rate for scalable technologies that produce hydrogen by splitting water.

The technique uses a specially designed chamber with a “Swiss-cheese” black silicon interface to split water and isolate hydrogen gas. The process is aided by bacteria that generate electrical current when consuming organic matter in the wastewater; the current, in turn, aids the water splitting process. The team, led by Zhiyong Jason Ren, professor of civil and environmental engineering and the Andlinger Center for Energy and the Environment, chose wastewater from breweries for the test. They ran the wastewater through the chamber, used a lamp to simulate sunlight, and watched the organic compounds breakdown and the hydrogen bubble up.

The process “allows us to treat wastewater and simultaneously generate fuels,” said Jing Gu, a co-researcher and assistant professor of chemistry and biochemistry at San Diego State University. The researchers said the technology could appeal to refineries and chemical plants, which typically produce their own hydrogen from fossil fuels, and face high costs for cleaning wastewater. Historically, hydrogen production has relied on oil, gas or coal, and an energy-intensive method that involves processing the hydrocarbon stock with steam. Chemical manufacturers then combine the hydrogen gas with carbon or nitrogen to create high-value chemicals, such as methanol and ammonia. The two are ingredients in synthetic fibers, fertilizer, plastics and cleaning products, among other everyday goods. Although hydrogen can be used as a vehicle fuel, the chemical industry is currently the largest producer and consumer of hydrogen. Producing chemicals in highly industrialized countries requires more energy than producing iron, steel, metals and food, according to a 2016 report from the U.S. Energy Information Administration. The report estimates that producing basic chemicals will continue to be the top industrial consumer of energy over the next two decades. “It’s a win-win situation for chemical and other industries,” said Lu Lu, the first author on the study and an associate research scholar at the Andlinger Center. “They can save on wastewater treatment and save on their energy use through this hydrogen-creation process.”

According to the researchers, this is the first time actual wastewater, not lab-made solutions, has been used to produce hydrogen using photocatalysis. The team produced the gas continuously over four days until the wastewater ran out, which is significant, the researchers said, because comparable systems that produce chemicals from water have historically failed after a couple hours of use. The researchers measured the hydrogen production by monitoring the amount of electrons produced by the bacteria, which directly correlates to the amount of hydrogen produced. The measurement was at the high end for similar lab experiments and, Ren said, twice as high as technologies with the potential to scale for industrial use. Ren said he sees this technology as scalable because the chamber used to isolate the hydrogen is modular, and several can be stacked to process more wastewater and produce more hydrogen. Though a lifecycle analysis has not yet been done, the researchers said the process will at least be energy neutral, if not energy positive, and eliminates the need for fossil fuels to create hydrogen. The researchers said they will likely experiment with producing larger amounts of hydrogen and other gases in the future, and look forward to moving this technology to industry.

Listeria monocytogenes is a bacterium which can give rise to food poisoning and so is a serious food safety concern in food production.

In 2015 according to Public Health England, there were 169 cases of listeriosis in England and Wales. This might not sound many, but the mortality rate for this pathogen is high at approximately 30% of cases.
The elderly and unborn / newly-born babies are most vulnerable to the disease. Listeria monocytogenes is the only member of the genus Listeria which is recognised as a human food pathogen. However, all Listeria species have the same growth requirements, and so the presence of a ‘non-hazardous’ Listeria can be indicative of the presence of Listeria monocytogenes.

Listeria is found in the general environment and so can be associated with any food that is grown in association with the soil (e.g. salad leaves). This bacterium can:

• Grow – albeit slowly – at chill temperatures and is especially a concern for chilled ready-to-eat (RTE) foods.
• Inhabit and persist in the food production environment. It thrives in conditions where there is plenty of water
• Produce protective mechanisms (for example ‘biofilms’) to help it survive.

These characteristics enable Listeria and Listeria monocytogenes to cross-contaminate foods that have undergone a process to eradicate vegetative pathogens (e.g. cooking), and so it can pose challenges to food manufacturers.

Where to look for Listeria
When monitoring for the presence of Listeria in a food production facility there are key areas to look at. Two of the most frequently contaminated are:

1. Drains are the prime place to look for this bacterium, because each time the production area is cleaned, residue leaves via the drains.
2. A close second on the list of places to look is ‘cleaning equipment’ such as brushes and squeegees, which are used as part of any clean-down process. Most, if not all, cleaning equipment will be used as part of routine cleaning.
