Sewage treatment is the process of removing contaminants from wastewater, primarily from household sewage. It includes physical, chemical, and biological processes to remove these contaminants and produce environmentally safe treated wastewater (or treated effluent). A by-product of sewage treatment is usually a semi-solid waste or slurry, called sewage sludge that has to undergo further treatment before being suitable for disposal or land application.
- Eliminates or reduces need for toxic and expensive chemicals
- Reduces sludge production and handling
- Reduces BOD, COD, TSS - within Pollution control board norms
- Reduces aeration requirement
- Treated water can be used for irrigation
Initial dosage is 50ppm which is to be applied on a daily basis for 7-10 days.
Then you can evaluate and apply according to your desired COD & BOD level.

| Precautionary statements - response |
IF SWALLOWED: Rinse mouth. Do NOT induce vomiting. IF ON SKIN (or hair): Take off immediately all contaminated clothing. Rinse skin with water/shower. IF INHALED: Remove person to fresh air and keep comfortable for breathing. Immediately call a POISON CENTER or doctor/ physician. IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Immediately call a POISON CENTER or doctor/ physician.
Wash contaminated clothing before reuse. Absorb spillage to prevent material damage. |

| Eye Contact |
Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Get medical attention immediately. |
| Skin Contact |
Wash off immediately with plenty of water for at least 15 minutes. Use a mild soap if available. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention immediately. |
| Inhalation: |
If inhaled, If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a physician. |
| Ingestion: |
If swallowed, do not induce vomiting. Allow victim to rinse his mouth and then to drink 2-4 cupfuls of water. Never give anything by mouth to an unconscious person. Call a physician. |
| Notes to Physicians | Treat symptomatically. |

| Flamibility | Not Flammable |
| Suitable extinguishing media | Use extinguishing measures that are appropriate to local circumstances and the surrounding environment. |
| Protective Equipment | Use personal protective equipment. |
| Hazardous combustionproducts | May release hazardous gas |
| Advice for firefighters |
Wear self-contained breathing apparatus. Wear full protective equipment. Because fire may produce toxic thermal decomposition products, wear a self-contained breathing apparatus (SCBA) with a full face piece operated in pressure-demand or positive-pressure mode. |
| Specific extinguishing methods |
Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations. In the event of fire and/or explosion do not breathe fumes. |

| Personal Protectiv | Wear appropriate PPE Kit |
| Spillage |
Leaks may be located by spraying the area with ammonium hydroxide solution which forms a white fume in the presence of sulfur dioxide. |
| Enviromental Precaution |
Do not allow contact with soil, surface or ground water.If the products get into drains, inform the relevant authorities immediately. |
|
Methods and materials for containment and cleaning up |
Stop leak if safe to do so. Contain spillage, and then collect with noncombustible absorbent material, (e.g. sand, earth, diatomaceous earth, vermiculite) and place in container for disposal according to local / national regulations (see section 13). Flush away traces with water. For large spills, dike spilled material or otherwise contain material to ensure runoff does not reach a waterway. |

| Advice on safe handling |
Do not ingest. Do not get in eyes, on skin, or on clothing. Do not breathe dust/ fume/ gas/ mist/ vapors/ spray. Use only with adequate ventilation. Wash hands thoroughly after handling. |
| Storage |
Do not store near acids. Keep out of reach of children. Store in suitable labeled containers. Store in areas, away from heat and moisture and protected from physical damage. Segregate from acids and oxidizers. |
| Advice on general occupational hygiene |
Wash hands after use. Do not to eat, drink and smoke in work areas. Remove contaminated clothing and protective equipment before entering eating areas. |

| Engineering Control |
Provide general or local exhaust ventilation systems to maintain airborne concentrations below OSHA limits . Local exhaust ventilation is preferred because it prevents contaminant dispersion into the work area by controlling it at the source. |
| Personal Protection |
Eye protection : Wear eye protection/ face protection. Gloves should be discarded and replaced if there is any indication of degradation or chemical breakthrough. Skin protection : Personal protective equipment comprising: suitable protective gloves, safety goggles and protective clothing |
| Respiratory protection |
Follow OSHA respirator regulations (29 CFR 1910.134) and, if necessary, wear a MSHA/NIOSH-approved respirator. Select respirator based on its suitability to provide adequate worker protection for given working conditions, level of airborne contamination, and presence of sufficient oxygen. For emergency or non-routine operations (cleaning spills, reactor vessels, or storage tanks), wear a SCBA. Warning! Air-purifying respirators do not protect workers in oxygen-deficient atmospheres. |
| Hygiene measures |
Handle in accordance with good industrial hygiene and safety practice. Remove and wash contaminated clothing before re-use. Wash face, hands and any exposed skin thoroughly after handling. Provide suitable facilities for quick drenching or flushing of the eyes and body in case of contact or splash hazard. |

It may, in acidic solutions, release toxic and hazardous fumes of sulfur oxides, including sulfur dioxide. Acute poisoning from sulfur dioxide is rare because the gas is easily detected. It is so irritating that contact cannot be tolerated. Symptoms include coughing, hoarseness, sneezing, tearing, and breathing difficulty. However, workers who cannot escape high accidental exposure may suffer severe pulmonary damage which can be fatal. Contact with powdered potassium, sodium metals, alkali, and oxidizing agents produce violent reactions. Reacts with water and steam to form corrosive sulfurous acid. Reacts with chlorates to form unstable chlorine dioxide |
| Hazardous Decomposition |
Decomposition products may include the following materials: |
| Condition to Avoid | Avoid excessive heat, or open flame. |
| Polymerization | Will not occur. |

| Route of Exposure | Inhalation, Eye contact, Skin contact |
| Eye Effects (rabbit) | Not available. |
| Skin Effects (rabbit): | Not available |

Prolonged or repeated exposure may cause dermatitis, and sensitization reactions. Exposure to asthmatic, atopic and sulfite sensitive individuals may result in severe bronchoconstriction and reduced levels in forced expiratory volume. Acidic decomposition of sodium sulfite may release toxic and hazardous fumes of sulfur oxides, including sulfur dioxide, which may cause permanent pulmonary impairments from acute and chronic exposure. |
