5 R- Reduce, Reuse, Recycle, Refuse, Recover

  1. 1. REFUSE, REDUCE, RECYCLE, REUSE, RECOVERY Akash Tikhe akashtk92@gmail.com
  2. 2. RECYCLING  Recycled water, is former wastewater that is treated to remove solids and certain impurities, and used in sustainable landscaping irrigation or to recharge groundwater aquifers.  Recycled water can be use for agricultural and landscape irrigation, industrial processes, toilet flushing, and to recharge ground water basins.
  3. 3. USE OF RECYCLED WATER  Agriculture  Landscape  Public parks  Golf course irrigation  Cooling water for power plants and oil refineries  Processing water for mills, plants  Toilet flushing  Dust control  Construction activities  Concrete mixing  Artificial lakes
  4. 4. REUSE  Water reuse describes the process whereby wastewater treated to an appropriate standard, is reused for a variety of beneficial purposes. The treated water ready to be reused is termed recycled or reclaimed water.
  5. 5. TYPE OF WASTEWATER FOR REUSE Greywater Bathroom, washbasin, laundry, kitchen waste Blackwater Toilet flushing toilet flushing clothes washing gardening suitable only for outdoor use i.e. groundwater recharge, fountains
  6. 6. REUSE OF GREYWATER
  7. 7. GREYWATER TREATMENT  The treatment may be biological, chemical or mechanical.  The qualities of treated water they produce can vary considerably, as well as their energy consumption and initial cost.
  8. 8. DISINFECTION  Disinfection is required for indoor re-use of greywater, which requires regular maintenance.  Chlorine is most commonly used for disinfection. However, it has adverse environmental impacts.  Alternatives disinfectant can be ultraviolet (UV) or ozone.
  9. 9. RELIANCE PETROLEUM LIMITED, JAMNAGAR Wastewater Reclamation Plant (capacity=48,000 m³/d) LTDS (oily condensates & contaminated storm waters) TDS <500 mg/l Chloride <300 mg/l HTDS (oily wastewater & contains dissolved salts such as NaCI, neutralized spent caustic and contaminated cooling water TDS – 1000 to 2000 mg/l cooling tower for local green belt development irrigation Cooling tower Primary treatment API-separator and dissolved air flotation for oil removal ASP & Biotowers with plastic packings Dual media FiltersGranular Activated Carbon Biological treatment Tertiary FiltrationAdvance treatment Effluent Treatment Plant
  10. 10. ADVANTAGES  Use less water resources.  Irrigate your gardens during drought water restrictions.  Cut down the amount of pollution going into our waterways.  Help save money on new infrastructure for water provision and wastewater treatment.
  11. 11. ISSUES  Reusing greywater for washing clothes may cause discoloration of clothing due to dissolved organic material. This can be avoided by installing an activated carbon filter.  It cannot be stored untreated for longer than a few hours as it begins to turn septic and smell.  It can contain significant numbers of pathogens which spread disease.  The mode of living in home i.e. holiday home that have intermittent use
  12. 12. ISSUES  Seasonal variation in generation of wastewater  In order to re-use greywater indoors for toilet flushing and clothes washing you will need to firstly:  Separate greywater and blackwater waste streams.  Install a greywater treatment and disinfection  Financial cost of installing and maintaining a re-use system
  13. 13. REDUCE  Take a short shower  Use appropriate shower head  Wash full load for laundry  Regular maintenance and repairing of water leakages  Choose recycled product  Avoid using dishwasher  Water the lawn early in the morning  Avoid using running tap in wash basin while brushing and shaving  Avoid unnecessary flushing
  14. 14. REDUCTION OF WASTEWATER IN INDUSTRIES Key steps of Wastewater Management Step 1: Analyze manufacturing processes; gain an understanding of how wastewater is produced. Step 2: Develop a pollution prevention program based on the gained knowledge from analyzing the manufacturing process. Step 3: Choice of candidate treatment technology for proper process control and waste minimization.
