Ensure Biosolids And Sludge Stay Separated

Posted on

Waste producers have been trying to find more ways to make waste recyclable and reusable to conserve space in landfills and reduce air pollution. One of the methods that producers now use is separating sewage into biosolids and sludge. This helps reduce what has to be totally thrown out or incinerated, but for industries that produce and separate out biosolids, those and sludge must be kept separate, both for the integrity of the biosolids and the safety of those working with them.

Differences Between Biosolids and Sludge

Biosolids are the materials strained out of sewage that can be reused in different ways, such as on land. Biosolids have been treated to reduce pathogens and turn waste into what is essentially an organic substance that can be used as a form of fertilizer, for example. Biosolids are when produced correctly, not toxic, although they're not materials that you'd want to stand around in, of course. Sludge, on the other hand, is the true waste that can't be reused. By separating biosolids from sludge, though, the amount of sludge that needs disposal is substantially smaller. Because regulations for land application require the biosolids to meet high standards, you do not want to mix biosolids and sludge at all.

Sludge Safety Issues

Sludge, which can contain components called grit and screenings, can be very dangerous. This is true sewage, and there is a reason cities move sewage sludge away from populated areas. Exposure to grit and screenings can lead to health problems, as evidenced by testimony from a sludge trailer driver who had to haul a combination of biosolids, grit, and screenings and who had to clean out the trailer without much safety gear. Her health deteriorated badly over the course of her employment. For this reason, you do not want to send sludge back out with biosolids, and anyone at your facility who handles sludge needs complete protective gear. And, you want your trailer service to do the same.

Clean Trailers From a Hauling Service

Rather than get a trailer or two for your own company, ones that you'd be responsible for in terms of cleaning (and that could break down, leaving you with only one trailer for hauling both types of waste), contract with a dump trailer service. Arrange for separate, clean trailers for biosolids and sludge, and ensure that the company provides its workers with appropriate safety gear when handling the materials and cleaning the trailers.

If you can keep the biosolids from your facility separate and acceptable per land-application standards, you'll do the environment and society a great service. With the help of a hauling service with clean trailers, you should be able to provide good biosolids easily. Contact a company like Duffield Hauling INC for more information and assistance.
