The document describes root zone wastewater treatment technology. It aims to analyze wastewater treatment without preliminary treatment using this method. Various plants used include reeds, cattails, and canna lilies. Laboratory tests on influent and effluent showed reductions in turbidity, hardness, BOD, COD, nitrates, and phosphates of 50-90%, and increased dissolved oxygen. The system was effective at treating domestic and dairy wastewater without chemicals or energy inputs, making it suitable for decentralized use.

4. 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.

24. 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.
25. Future scope
1. No treatment facility or treatment
method is available for nallaha But the
root zone technology.
2.Best suitable for villages, small towns and
cities.
3.Decentralized waste water treatment
method.
4.Locally available material can be used and
not required skilled labor for
construction.
5.No mechanical equipment's are required
for operation.
26. 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.
27. Conclusion:
1. 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.
