Almost all human activities will produce biological wastes in many forms. It could be in the form of human waste or other waste materials containing infectious microorganisms. Such wastes must be treated lest they cause serious diseases. Various sanitation ways have proved useful when it comes to safeguarding the public’s health against diseases related to biological wastes. With a much understanding of how one can prevent disease transmission, it has become easier to implement effective management methods of handling contaminated waste. Here are some of the conventional measures applied to safeguard the public’s health.
1. Disposing of Human Waste
Factually, human fecal matter causes disease outbreaks like dysentery, typhoid, ascariasis, and polio, to mention a few. Human excreta have a high pathogen concentration, which easily pollutes food and water supplies. Some essential principles, like providing a physical barrier, can be used to reduce such cross-contamination.
Physical barriers applied in sanitary sewer systems include pipes and pumps, which transports pathogen-overloaded sewage to a treatment plant. Immediately the waste touches the sewer treatment plant; numerous mechanisms will minimize the likelihood of the waste causing diseases. Even medical waste disposal involving elements like syringes, blood, and other body fluids should be appropriately discarded to keep the environment safe from disease spread.
2. Sewer Treatment
When treating the sewer, there has to be biological degradation of the organic matter. Human pathogens can’t survive under the physical and biochemical conditions involved in the degradation process. This will significantly reduce the amount of viable pathogenic microorganisms that remain in the treated waste. The degraded organic load in the sewer from the sewage treatment plant undergoes a final process before it is let out into the surroundings. The final step is chlorination, ultraviolet exposure, as well as ozonation, which ensures pathogen buildup in the waste reduces to the satisfactory level. When the pathogens reduce, the environment will be safe not only humans but also for animals..
3. Disposal methods
Any solid waste and refuse generated by humans is polluted with biological elements. Such elements usually cause infections in man. When it comes to storage and disposal transport, the barrier system helps serves as protection of individuals handling the waste. Also, plastic waste storage bags or enclosed refuse vehicles offer barriers to reduce the likelihood of waste material contaminating the environment. Solid wastes get disposed of directly in sanitary landfills. The first step is to treat it by incineration to minimize its volume. Sanitary landfilling protects the health of the public.
The Bottom line
Whether it is medical waste disposal or human excreta disposal, it has to be done in the right way. As discussed above, also medical waste like contaminated syringes, blood, and other body fluids need proper disposal to prevent disease spread into the environment. Involving long-standing sanitation principles is useful when it comes to controlling all threats to general public health. This means applying special waste packaging techniques or on-site decontamination to minimize pathogen buildup to tolerable levels.
