Wash systems have become super important for maintaining clean roads and minimizing the spread of pathogens. The fact that they are often fully automated makes the process even simpler. But before you prepare to set up and operate these systems, you must consider the following: What happens to the wastewater? Whether you’re working on a construction site, driving along a strip mine, or transporting livestock and poultry, wash systems will generate grey water, sludge, and solids that have been removed from the vehicles. That’s where a solids separator comes in.

So what is a solids separator, and what is its function? As the name implies, it separates the solid materials (soil, rocks, etc.) from the water. This allows for a much easier disposal of both the water and the solid pollutants. Of course, failure to remove the solid waste also comes with its own consequences, including an increased potential for groundwater pollution, a build up and inevitable blockage in wastewater lagoons, and a persistent unpleasant odor.

There are multiple ways of constructing a solids separator, each with their own equipment and process. Let’s take a look at some examples:

• Sedimentation. Sedimentation is a passive process by which the grey water enters a special structure called a settling basin. In these, the solid material is allowed to settle to the bottom of the tank while the clear water slowly flows into a drainage pond.
• Evaporation. Evaporation of grey water can occur naturally (especially if you live in a warm climate) or by aid of special heating equipment. During this process, any solid materials are left behind as the purified water is evaporated into the atmosphere.
• Separators. Separators can be as passive or mechanical as you choose. Some separators are simply composed of screens through which grey water passes, catching large debris and other solid materials. Others involve heavy machinery that pump and press and whisk the water through a series of chambers to remove any sediment.
• Flocculation. Chemicals may be added to the water that will encourage sediments to cling together, making them much easier to capture and remove.

Here at Neptune Wash Solutions, our wash systems come with their own solids separators. We use flocculent to drop solids quickly and efficiently, ensuring that your tires are spic and span before heading out on the roads.
