Liquid waste is any liquid like fat, oil, or grease (FOG), wastewater, liquids, sludges, hazardous household liquids, or used oil. These liquids that are or can be harmful or hazardous to human life or the environment are called liquid waste. They can also include discarded commercial products like pesticides, cleaning fluids, or the by-products of manufacturing processes.
There are rules and regulations relating to these types of waste as well as for generating, storing, transporting, treating, and disposing of any liquid and/or hazardous wastes. Liquid waste is a growing concern worldwide, and must, by law, be properly disposed of, usually by a licensed waste hauler. Keep reading to learn the proper ways to deal with different types of liquid waste.
1. Sewage, Sullage, and Runoff
Liquid waste disposal and management focuses on getting rid of the waste safely, with no impact on the environment or human health. The most common types of liquid waste are sewage and sullage. Sewage is wastewater made up of human waste, while sullage is any wastewater that comes out of other household activities like laundry, dishwater, and bath water.
Runoff is water that comes from any natural activities like water from dams and ponds, streams, and rain. Runoff can bring with it different types of waste including human, so it can be a health hazard despite its natural cause.
2. Human Waste Management
There are a variety of ways to dispose of human waste, but there are several conditions that must be met, such as: the method must not contaminate groundwater or surface water; the waste must not be accessible to flies; and the method must not be unsightly or leave a bad smell. For the most part, human waste goes into a septic storage system and is removed by professionals, or it is put through a municipal sewage system.
3. Industrial Wastewater Management
Any type of wastewater that comes from industries is called affluence. Affluence produced by industries has to meet certain guidelines set out by the country, province, and in some cases, municipalities. For example, there is a limit on how much of a certain chemical may be released into a body of water.
4. Runoff Management
Perhaps one of the most dangerous types of waste to ignore is runoff, since it has the worst consequences if ignored. These issues are typically dealt with by municipalities.
5. Collecting, Storing, and Treating Liquid Waste from Industry
There are different ways to safely collect, store, and treat liquid waste, and all vary depending on the location, application, and type of waste. Companies that produce a large amount of liquid waste have two options: pay to truck it away for treatment elsewhere, or pay to have it treated on-site and then transported elsewhere for disposal. Recent technologies have improved the treatment of liquid waste streams so that liquid waste can be turned into a solid for better disposal. This process can reduce risk and liability, improve on-site safety, reduce current costs of managing liquid waste products, and significantly reduce environmental impact.
Types of liquid waste from industry might include mud (water or oil-based) from wells, hydro excavations, remedial excavations, and more. Current technology is vastly superior compared to more traditional methods for treating liquid waste. Adding huge amounts of lime or fly ash to a liquid until it meets solids criteria for taking to landfill is both redundant and wasteful.
The best way to deal with your industry’s liquid waste is to have your liquid waste stream analyzed so the proper reagent can be used to solidify the liquids for transport and disposal.
