You can define liquid waste as water that contains solid waste. The amount of dissolved waste should be less than one percent. How you dispose liquid waste will depend on how it impacts the natural environment. This kind of waste can contain highly dangerous dissolved salts and metals and they can also be hazardous in nature. After you have analyzed the nature of the liquid waste, to ascertain whether it is hazardous or not, you can dispose it in the following four methods -
This process involves removing the solid component from the water. You can, however, use this method only if the liquid waste is not hazardous. Sedimentation process involves a sediment basin. You will have to place this basin under a structure from where the liquid waste will flow out and the sediments in it would settle down in the bottom of the sediment basin. The remaining liquid would then be treated chemically or disposed. You will require a permit to carry out this method. It is usually used in construction sites.
Once you remove the sediments from the liquid waste, they are usually sent to the landfill or buried underground if they are hazardous. In order to avoid this, you can use the method of incineration. This process involves treating the liquid waste in high temperature. Two methods of treating liquid waste by incineration are fluidized bed furnaces and multiple hearth furnaces. If you want to treat your liquid waste through incineration, you will have to follow air pollution safety measures. The process results in the creation hazardous gases like carbon monoxide.
You can also use composting for disposal of liquid waste. This process changes the dissolved matter into highly nutrient fertilizer. With this process, you can change a waste matter into something that is rich in nutrients like nitrogen, potassium by eliminating the pathogens and disease causing germs from them. This compost because of its high nutrient content acts as good manure and fertilizers.
- Root Zone Treatment Method
You can use this method to treat liquid waste that you have gathered from places like the kitchen, toilet and bathroom. With this method you first use a sedimentation tank to separate the solid matter from the liquid waste, the water is filtered through gravel filtration and then at the polishing pond, the water is finally treated to remove the bacteria.
