Introduction
According to the World Health Organization, there are diverse sets of waste streams that require appropriate management around the global communities. The essential point is to assess what type of waste that affects the environment. There is also need to understand every individual who is responsible for tracking as well as managing every waste stream in the society. Besides, during the management of waste stream, it is necessary to determine the volumes of each generated along with the associated costs in the process of the directorate (Treating hazardous liquid waste, 2012). It is not strange around the society to find that several people or no single individual have historically been responsible for tracking the particular waste stream. According to Savage (2013), some types of waste stream have particular regulatory needs in addition to the general regulation of wastes. Therefore, the primary target of this report is to describe hazardous liquid as a waste stream. The report also focuses on describing chemical and physical traits of dangerous liquid wastes, the most significant problems of m
anaging it, the regulations that apply to it, analyzing different technologies, and management techniques of hazardous liquid wastes. Finally, it makes the argument for the best course of action for managing hazardous liquid as the waste around the globe.
Chemical and physical characteristics of the hazardous liquid waste
Hazardous liquid wastes are always classifiable based on their biological, physical, together with chemical properties. These properties of these wastes generate materials regarded either to be toxic, reactive, corrosive, ignitable, radioactive, or infectious. Chemical characteristics of hazardous liquid wastes are that they are flammable, corrosive, reactive, or something explosive. Hazardous liquid wastes are also toxic or something poisonous to living things when they are applicable in any way to support life (Scotford, 2013). There are different types of ignitable forms of Hazardous liquid wastes. It comes in the form of liquid with the flash point that has the lowest temperature at which fumes above waste ignite at sixty degrees like alcohol, acetone, and gasoline. Conversely, physical characteristics of hazardous liquid wastes are diverse as it looks at the temperature, odor, and robust state. Hazardous liquid wastes may be solid as some contain particles of solid materials carried along in the flow. The particles carried in the flow maybe settleable solids or suspended solids. In most cases, settleable solids always sink to the bottom when the speed of flow reduces (carlini et al., 2013). However, suspended solids in v refer to the small particles that tend to remain in suspension in the liquid, as they did not dissolve in the wastewater but carried along with the fluid. The temperatures of Hazardous liquid wastes are warmer than the ambient temperature. Such cases a rise because warm liquid may be inclusive in the waste stream from various human activities like cooling of engines and showering. Besides, Hazardous liquid wastes can have an odor generated due to the generation of different gases as the result of biodegradation in the waste liquid.
Most significant problems with managing hazardous liquid waste stream
The significant problems with managing hazardous liquid wastes lie on the processes of collection, treatment, as well as disposal of such wastes. The problem occurs when the handling of these materials is not proper. Improper handling of these materials always causes the substantial harmful effect to human safety and health or the ecosystem. The problems of managing hazardous liquid waste arise due to inadequate transportation, storage, treatment, or removaloperations (Schlegelmilch et al., 2015). Improper dangerous liquid waste dicarding or storage of such wastes regularly contaminates the ground along with water with groundsupplies. Therefore, persons that reside in homesteads constructed near aged and abandoned sites of hazardous liquid waste disposal remain to be in danger location. To remedy the issues that exist and to avoid prospect harmful effects from dangerous liquid wastes, managements need tocontrol the exercise of managing harmful liquid trashes tightly.
Regulations that apply to Hazardous liquid wastes stream
All generators of wastes except households are require by regulations of every state to determine if any of their waste is problems with managing hazardous liquid waste stream. The generators have the laws of keeping records of their waste evaluations and other information utilized to determine the type of waste at least three years after shipping, treatment, storage, and disposal of waste. Therefore, the regulation lies much on proper management of hazardous liquid waste stream. These stated rules apply to all business operators, not just manufacturing sector. All facilities of activity must determine if the waste products that they generate during their operations is hazardous or non-hazardous (Siko, 2013). The regulation set by the health authorities’ advice the manufacturers to label containers that hold these dangerous liquid waste streams as hazardous waste. The labeled container should be placeable in the satellite accumulation area (SAA). The company must also evaluate the process to analyze the waste as the means of meeting HWHF that is a criterion for waste acceptance. The generator of the report must also submit a complete hazardous liquid waste disposal requisition that supports the documentation (Morrissey & Browne, 2014). Waste management staffs also have the mandate of evaluating the request for pickup for complete generator training, full details about the waste, complete generator data, and accumulation start date. All these regulations follow before the packaging and storage of waste that awaits disposal off site.
Treatment technologies and management techniques for the hazardous liquid waste stream
Management of hazardous liquid waste alters the unused materials into less risky or environmentally gentle liquidsby biological, physical, chemical, or process of thermal. These procedures go along with the dispersal or disposal of solid, liquid, or products of gases or remainders under controlled settings. Due to the broadly conflicting chemical along with physical traits of the risky liquid waste stream, technologies of treatment and management techniques are always careful in matching each type of waste (Scotford, 2013). The technology takes into consideration the nature of residues, the degree of hazard reduction needed along with economic conditions among other factors. Novel physicochemical processes during treatment have developed to use a combination of chemicals (Ikhlayel, 2017). The techniques often work by the aid of passage of the electrical current that the assistance in oxidizing and recovery constituents in the waste from aqueous solutions. Besides, the technologies in biological processes have resulted in systems that assist in permitting faster rates of degradation. It also allows the treatment of high levels of contamination by raising the temperature as well as improving transfer rates of oxygen in the liquid. All these treatment technologies and management techniques for the hazardous liquid waste aim at recycling and reusing the wastes.
Best course of action for managing the hazardous liquid waste
The use of technology that provides immediate and very high degrees of hazard reduction is the best action to take in the administration of hazardous liquid trash. The use of source segregation provides the simplest and probably the least costly approach to managing hazardous liquid waste. The action of using source segregation as a way of managing these wastes stops pollution of large amounts of non-dangerous trash by elimination of hazardous elements to form dangerous liquid dissipate. The firms should embrace such approach in reducing and managing the amount of waste that they generate (Hsieh & Erdogan, 2014). For instance, metal finishing rinse in clean water is renderable to be nonhazardous by separation of toxic metal. The used liquid in cleaning metal can then be disposable through industrial sewage systems as non-hazardous (Tsai, 2011). In conclusion, it is essential for every individual in the society to be responsible for keeping track of what type of materials is going into the waste container for various reasons. Managing hazardous liquid waste should be a personal and workplace safety issue. Therefore, keeping track of what goes in the waste container helps an individual along with institution in maintaining the environmentally sustainable place to support and maintain its objectives for operations.
