Rules apply to
all persons who generate, collect, receive, store, transport, treat, dispose or handle biomedical waste in any form
Prescribed Authority for enforcement of the provisions of the rules
State Pollution Control Board
Responsibilities of Occupier Take all steps to handle wastes properly without causing any adverse effect to human health and the environment
Obtain authorization Submit annual returns Maintain records Report accidents
Occupier of a health care institution - Person who has control over that institution and/or its premises
Why Biomedical Waste goes untreated?
Pollutants are invisible Authorities are overburdened with
their prime duties Lack of awareness Lack of training Lack of dedicated manpower for
waste management
The purpose of legislation is to
1. To prevent the spreading of infection
2. To prevent the reuse of disposable items discarded from the hospitals

If a container is transported from its originated premises to any waste treatment facility outside the premises, it shall also carry information prescribed in schedule 4 apart from a label prescribed in schedule 3.
Biomedical waste shall be treated and disposed in accordance with schedule 1 and in compliance with the standards in schedule 5.
Every occupier has to obtain authorization of state pollution control board under biomedical waste rules.
Every occupier/operator shall submit an annual report to the prescribed authority in for 2 by 31 Jan every year including details on categories and quantities of biomedical waste handled during the preceding year.
Every authorized person shall maintain records related to generation, collection, reception, transportation, treatment, disposal of biomedical waste in accordance with these rules and guidelines.
When an accident occurs at any institution for biomedical waste treatment or during its transportation, the authorized person shall report the accident in Form 3 to the prescribed authority.

IMPACT OF THE POLLUTANTS ON ENVIRONMENT
Parameter Impact on Environment
1.Odour Poor apetite for food, lowered water consumption, impaired respiration, nausea and vomiting, mental perturbation ,deterioration of personnel and community pride, interfere with human relations, discourage capital investment, lower socio-economic status and deter growth.
2.Colour Inhibits penetration of light to water limiting photosynthesis by microorganisms and thereby adversely affecting natural oxygenation of water.
3.Turbidity Inhibits penetration of light to water limiting photosynthesis by microorganisms and thereby adversely affecting natural oxygenation of water.
4. Total dissolved solids (inorganic)
Inhibits penetration of light to water limiting photosynthesis by microorganisms and thereby adversely affecting natural oxygenation of water.
5. Suspended solids Aesthetically displeasing and provided adsorption sites for chemical and biological agents. Organic solids may be degraded, biologically, resulting in objectionable by-products. Biologically active (live) suspended solids may include disease-causing organisms as well as organisms such as toxin- producing strains of algae.
6. pH Alter the concentration of hydrogen ion in the receiving water body.
7. BOD Deplets dissolved oxygen from water causing danger to aquatic life.
8. COD Depletes dissolved oxygen from water causing danger to aquatic life.
9. Chloride Bitter taste, Free chlorine toxic to fish and other aquatic life.
10. Sulphate Products H2 SO4 which is corrosive.
11. Phosphate Overgrowth of objectionable plant forms (eutrophication), may bring about oxygen depletion in water.
12. Nitrogen Nitrate poisoning can cause death,’blue body’ syndrome (methamog lobinemia)
13. Oil and grease Interfere with the biological life in the surface waters and create unsightly floating matter and film, cut off sunlight from water limiting photosynthesis by microorganisms and thereby affecting the natural oxygenation of water.
14. Pathogenic Organisms Cause disease of gastro-intenstinal tract such as typhoid and paratyphoid fever, dysentery, diarrhoea and cholera.
METHODS AND EQUIPMENTS FOR WASTE WATER TREATMENT

To remove organic matter biologically
Trickling filters, activated sludge process , fluidized bed bio-reactors, rotating biological contactor, aerated lagoon
b. AnaerobicAnaerobic lagoon, anaerobic contactor and filter, anaerobic fluidized bed bioreactor
