best Eco-friendly and economical method of waste water treatment.this technology no need add any chemical to remove the pollutant from waste water. this method is very useful for small towns, villages, bungalows, hotels and nallha system.
Conclusion:
As per our Tested samples Turbidity, Hardness, BOD, COD, Nitrate, Phosphate,etc get Redused and DO increased.
2. Concentration of COD was high of dairy waste water.
3. The Reactor was found to be very effective for sewage treatment.
4. Turbidity of domestically and dairy waste get removed about 88.63% and 44.89% respectively.

WASTE-WATER TREATMENT BY USING ROOT ZONE TECHNOLOGY AKSHAY SHINDE
INDEX INTRODUCTION WHAT IS EXACTLY AIMS AND OBJECTIVES TYPES OF PLANTS PROPERTIES AND NECESSSITY OF MATERIAL PROCEDURE AND METHODS RESULTS AND DESCUSSION APPLICATION AND FEAUTURE SCOPE CONCLUSION
INTRODUCTION
INTRODUCTION: Root zone technology is effective technology called Decentralized Wastewater Systems (DEWATS) It was developed in 1970s in Germany and has been successfully implemented in different countries mainly in Europe and America. The root zone wastewater treatment system makes use of biological and physical-treatment processes to remove pollutants from wastewater. Due to its natural process, there is no need to add any input such as chemicals, mechanical pumps or external energy. This reduces both the maintenance and energy costs.

What is exactly ? It is the set of technologies / methods based on various mechanisms associated with root-zone of different plants . This system leads to be- Decontamination, destruction, containment of Pollutants .
aim: To cheak the feasability of root zone technology for treatment of wastewater without any priliminiry treatment. objective: Analysis of waste water at inlet and outlet with DO, COD, BOD, Nitrate, Phosphate by laboratory test

Turbidity test (domestic VS Dairy) Inlet vs outlet Turbidity domestic Vs Dairy waste
Hardness test (domestic VS Dairy) Inlet vs outlet Hardness test domestic Vs Dairy waste
Total Solids test (domestic VS Dairy) Inlet vs outlet Total solids test domestic Vs Dairy waste
DO test (domestic VS Dairy) Inlet vs outlet DO test domestic Vs Dairy waste
BOD test (domestic VS Dairy) Inlet vs outlet BOD test domestic Vs Dairy waste
COD test (domestic VS Dairy) Inlet vs outlet COD test domestic Vs Dairy waste
Nitrate test (domestic VS Dairy) Inlet vs outlet Nitrate Test domestic Vs Dairy waste
Phosphate test (domestic VS Dairy) Inlet vs outlet Phosphate Test domestic Vs Dairy waste
Applications Bathroom water recycling. Treatment of polluted streams, nallas, rivulets and water-bodies ( floating beds may be recommended. Use recycled water for flush, dish washes, watering for plant.
Future scope No treatment facility or treatment method is available for nallaha But the root zone technology. Best suitable for villages, small towns and cities. Decentralized waste water treatment method. Locally available material can be used and not required skilled labor for construction. No mechanical equipment's are required for operation.
Advantages of this treatment method Roots of plants provide favorable environment for bacteria Diversity thereby reducing pollutant loads. Least consumption of electricity. Use of gravity for water flow. Complete biological and Eco friendly method of treatment. No foul odor is released.
Conclusion: As per our Tested samples Turbidity, Hardness, BOD, COD, Nitrate, Phosphate,etc get Redused and DO increased. 2. Concentration of COD was high of dairy waste water. 3. The Reactor was found to be very effective for sewage treatment. 4. Turbidity of domestically and dairy waste get removed about 88.63% and 44.89% respectively.
