How to Increase Your Removal Rates

You buy an oil skimmer that will get the job done the first time around!

Industrial wastewater pits are treacherous. Nasty, bubbling, caustic black ooze swirling about in water is something nightmares are made of. The thought of having to remove all of that nasty seems like a daunting task and for some plant operators, it is. Keeping the wastewater clean is crucial for steel mills. Contaminated water can result in sludge formation, producing environments for bacteria to grow and thrive, the production of rust and corrosion, and a list of other horrific things that will cause pain and misery to the equipment and application as a whole. Some facilities just need to keep the wastewater clean, while others need to keep it clean and reclaim the used oil. It’s a big job to take on and not all oil skimmers are cut out for the challenge.

The pit of dispair. Or just a normal day in a steel mill office.

Recently, we had a customer contact us about a steel mill operation that didn’t seem to be running as it should. Our salesman, John, visited the location to get a better understanding of what was going right or wrong. The company was using a competitor’s tube skimmer and this particular model was just not able to handle the grime and muck in a manner that was productive for the operators. The oil removal rates were low and recovery of the waste oil was not as efficient as they were hoping.

These are big tanks that need a big oil skimmer to tackle the jobs at hand, both cleaning the wastewater and a way to reclaim used oill. After going over the specifications of the tanks and getting a better understanding of what kind of results the plant operators were trying to achieve, John knew that the operation would benefit immensely from implementing a Model MB Oil Grabber.

The Model MB utilizes continuous belts and wipers to remove up to 200 gallons of oil per hour from the fluid surface. The belts, operating on a motor and pulley system, run through contaminated liquid to pick up oil from the surface. After traveling over the head pulley, the belts pass through tandem wiper blades where oil is scraped off both sides of each belt and discharged. The tail pulleys have flanges which allow them to roll freely on the inside of the belts without becoming dislodged. These lower pulleys require no bearings and do not need to be fastened to the tank. If turbulent conditions exist, an optional tether and cage assembly prevents the tail pulleys from being dislodged.

The Model MB was designed for applications like this. When removal capacities are not being achieved in an application, you bring out the heavy duty equipment. The Model MB is available in multiples of 2, 3, or 5 belts. Wastewater sumps, coolant sumps, outdoor lakes, ponds, or basins, underground tanks, food processing plants, parking lots, garages, service facilities, truck, locomotive, and other mobile equipment washing stations have all benefited from using the Model MB as a wastewater cleaning system.

This skimmer was built to last for years in harsh environments. It can handle temperatures up to 212°F and in pH levels ranging from 1-13. The belts are made up of corrosion-resistant steel, carbon steel, or a specially engineered polymer. The Model MB requires very little space in the tank or sump, easily mounts, and requires very little maintenance.

After replacing the former skimmers with the Model MB, the company reported the recovery rates are 4x higher than before.
