Tracking the tiniest cracks – with H2O wastewater treatment. Heavy use, material fatigue and material faults can cause tiny cracks in plastic and metal parts. These are so small that they are invisible to the naked eye. But they can still be relevant to safety, e.g. on the wings of passenger jets. That’s why these parts are regularly checked for micro cracks. One way of doing this is the dye penetration process, where the part to be checked is first thoroughly cleaned. Applying a special dye and using a suitable developer, the tiniest cracks become visible on the surface, enabling defective parts to be easily identified and replaced. If the crack check reveals no problems, the transfer agents are washed and approved for further operations.

Packaged-food producers frequently use and then must discard large batches of cooking oil used in their process. Usually they drain most of the oil directly from equipment, but they must remove residual oil by regularly washing fryers, ovens, conveyors, and other machinery.
The oil mixes with the wash water and becomes part of the plants wastewater stream. Having oil in wastewater complicates the wastewater-treatment process by making it more expensive, more time-consuming, and less effective. Additionally. as with other manufacturers, packaged-food producers want to reduce waste and decrease the environmental impact of operations. That is why removing used oil and solids from wastewater before it is discharged is a priority.

Direct reuse of wastewater in the product is not on the menu in the food and beverage industry, but the reuse of water for other purposes (e.g. washing) is now a priority. Most major F&B companies have made commitments to reduce their water consumption per unit of product, and reuse is an important part of the strategy for achieving this. Furthermore much of the growth of the industry is in emerging markets which typically have more limited, lower quality water resources than developed countries, creating water treatment challenges. In developed markets, emerging concerns about pharmaceutical by-products and other trace contaminants making their way into the product have lead to greater use of desalination technologies on the process water side. Value from waste propositions such as energy recovery, water reuse (not within the product) and materials recovery ensure that investment in water technology benefits the bottom line.

Welding fumes & gases are Unbreathable. Nonetheless, welding is perhaps the most common industrial process and necessary anytime the joining of metals is required. Regardless of the welding equipment type or technology, the simple process of melting metal and filler materials creates poisonous fumes and gases. ? Different types of welding processes present unique challenges to adequately handle airborne fumes. Robotic welding equipment and other automated welding systems produce a high volume of welding fumes and sparks and need to captured by a heavy duty robotic welding hood. Moreover, manual stick welding typically produces a high volume of smoke and often requires a self-cleaning fume extractor to avoid overwhelming the filters.? Lighter duty applications like MIG welding generally produce less particulate and light-duty TIG welding generates the least amount of smoke. It is important to not only consider the type of welding process but also the work piece material in order to select the correct filtration media for your application. HEPA filters are recommended for stainless steel welding, Nanofiber filters for Aluminum and parts containing higher levels of Manganese. Polyester filters are appropriate where rust inhibitor, lubricants and coatings create an oily smoke as these filters can be washed in water. Diversitech offers a complete line of fume collection machines from compact welding fume extractors to central welding fume filtration systems. We specialize in engineered solutions and our engineering team is experienced in selecting the best equipment and filter media for your particular application. We can present you with detailed technical drawings demonstrating several potential layouts and solutions including costing, installation and start-up expenses. ??
