Classification on waste based on the Shape or the Form Classification:
- “Solid waste”: solid waste is defined as the rest of the day to day activities of human and/or natural processes that shaped solid.
- “Liquid waste”: is the rest of the exiles the process of production or domestic activity in the form of liquid.
- “Gases Waste” is waste that utilize air as a medium. Naturally the air contains chemical elements such as O2, N2, NO2, CO2, H2 etc.
Solid waste is defined as the rest of the activities of human and/or natural processes that shaped solid. Or, solid waste is the waste that is solid composed of organic material and inorganic material that is considered no longer useful and should be managed so as not to harm the environment and protect the investment of development.
Then based on the Term Environment for the Management, solid waste is a material which is wasted or thrown away from the source of the result of human activity and natural processes that do not yet have economic value. Thus, the solid waste is the rest of the/a result of human activity, which is shaped organic and inorganic substances that can harm the environment so that the necessary management and processing. Solid waste can be generated from different types of activities such as residential, office, industrial, schools, markets and other public facilities.
Water quality management and water pollution control, explain the meaning of the waste that remains of a results business and or activities that are in liquid form. Understanding liquid waste other is the rest of the exiles the process of production or domestic activity in the form of liquid. Waste liquid can be either water and material waste another mixed (suspended) or dissolved in water.
Liquid waste is sourced from factories that typically use a lot of water in the system process. In addition, there is also a raw material containing water so that in the process of processing water must be disposed of. The water entrained in the process of processing and then discarded for example when used to wash the material before being processed further. Water plus certain chemicals are then processed and after it is removed. All types of this treatment resulted in the waste water.
The liquid waste is not handled or processed, may cause a great impact on environmental pollution and can be a source of disease for the community. Industry primary processing of forest products is one of the contributors of the liquid waste which is harmful to the environment. For major industries, such as pulp and paper industry, the technology of processing of liquid waste that it generates may already adequate, but not so for the industry of small or medium. In addition, domestic wastewater is usually not too concerned with whether whereas if allowed to continue in the long term can be a problem for the environment and public health. For example, waste water detergent rest of the laundry when left in the long term will be a source of environmental pollution and become a source of disease for the community. Given the importance and magnitude of impact caused by liquid waste to the environment, so it is important for the industrial sector and domestic to understand the basics of technology of processing of liquid waste.
Wastewater treatment technology is key in preserving the environment. Any kinds of processing technology of domestic waste water and industrial built to be operated and maintained by the local community. Processing technology selected must comply with the technological capabilities of the community concerned. Liquid waste processing can be grouped into three, namely: processing in biology, processing in physics, and processing chemicals.
The waste gas is waste that utilize air as a medium. Naturally the air contains chemical elements such as O2, N2, NO2, CO2, H2 etc. The addition of gas into the air that goes beyond the content of the air will naturally degrade the quality of the air. Waste gas that is produced in excess can pollute the air as well as can interfere with the health of the community. Contaminants through the air is classified into two parts, namely the particles and gas. The particles are fine grain and it may still be visible to the naked eye such as water vapor, dust, smoke, mist and fume. While pollution in the form of gas can only be perceived through the sense of smell (for gas specific) or a direct result.
The waste gas is discharged into the air typically contains material particles of solids or liquids is very small in size and lightweight so suspended with these gases. Material solids and the liquid is referred to as particulate matter. Such a waste gas that is produced by a plant can emit gases that form smog, particles as well as dust. If this is not captured by using a tool, then assisted by the wind will provide a range of pollution wider. The types and characteristics of each type of waste will depend on the source of waste.
