When you’re grinding and polishing concrete, the process can be completed wet or dry. Wet is often preferred, if only because it has been around longer than dry grinding. Water is used during the wet process, cooling the diamond tooling and acting as a lubricant. While it limits exposure to dangerous dust particles, the wet process leaves a slurry paste.
Many industries, like stone, concrete, glass and tile, and petroleum, struggle to deal with their wastewater. It isn’t uncommon for them to rely on ineffective methods, like coagulating chemicals and vacuum systems, rather than something more effective like a filter press or other water filtration system. The idea of investing in a filter press also brings along with it fear
Have you ever heard the term, “mothballing”? If you refer to Dictionary.com, it will define the act of mothballing as to “stop using (a piece of equipment or a building) but keep it in good condition so that it can readily be used again.” Essentially, it is the act of keeping broken, unusable equipment in a corner where it collects
From January 22-25, we attended the World of Concrete conference in Las Vegas at the Las Vegas Convention Center. The informative seminars began on January 21 and lasted throughout the conference. At our booth, we discussed our state-of-the-art portable concrete slurry water filtration system. Not only did we enjoy the time at our booth, we had the chance to meet
Are you in the concrete industry? If you answered yes, then that means you also have wastewater and you’re going to need a way to dispose of it. It should go without saying, but that disposal site should not be down the drain untreated, casually dumped into a nearby freshwater resource, or left for absorption into the ground. Unlawfully dumping
Have you ever wondered (or feared) what would happen if you illegally dumped wastewater? Unfortunately, water pollution violations aren’t uncommon. Punishments range from civil to criminal violations that can lead to jail time. The decision is often dependent upon whether or not defendants understood that their behavior violated the federal Clean Water Act (and continued to act despite this). The
You might know that discharging waste into a storm drain is morally wrong, but did you know that it’s also very illegal? It’s important to understand the distinction between a storm sewer/drain and a sanitary sewer. The sewer contains underground pipes that carry water from your home (sinks, showers, toilets) to a wastewater treatment plant. At the plant, the
It might seem like a question with a clear answer: why do we recycle wastewater? Even though the answer seems obvious, we still don’t rely on recycling water like we should. Too often we use water without thinking about what happens when we’re done with it. Where does the water go from the bathroom sink after you wash your hands?
So you’ve run your cement wastewater and slurry through a filter press to clean it, and it’s ready to be reused or dumped—WRONG! You’re on the right path by making sure it’s clean and by not dumping wastewater, but you need to make sure the pH balance of the water is at the appropriate level. This is especially important when
If you’re in the concrete industry, you have wastewater (and in wet processes, slurry) and it needs to go somewhere. That somewhere should NOT be down the drain untreated, or thrown into a nearby body of water, or absorbed into the ground. Doing so subjects your business to fines, and it hurts the earth’s resources. We all need to take
