Abstract
Aim of the work
The work of this study is use the Down flow hanging sponge system
in treating groundwater for drinking purpose in the presence of new
Hydrazone chelator and its metal complexes to study their effects in
the treatment of heavy metal in the groundwater.
II- Introduction
This chapter includes an overview of previous researches for use
down flow hanging sponge in groundwater treatment and use of
Hydrazone chelator in heavy metals treatment and their application.
III- Experimental
This chapter contains the chemical and machines used in practical part
of thesis as follow:
1)The physic-chemical method measuring such as pH, temp., Total
hardness, calcium hardness, magnesium hardness, ammonia,fecal
coilform , total coliform and their heavy metal.
2) Preparation of the Hydrazone chelator and its metal
Complexes.
3) characterization of the ligand and its complexes
•Physical technique such as molar conductance and magnetic
Susceptibility.
•Spectral technique as IR, UV-Vis.
iv- Result and discussion
This chapter includes characterization of groundwater and use the sponge in treated it
and add the chelator to heavy metal treating where Downflow hanging Sponge (DHS)
system was module column consists of four identical segments connected vertically,
each segment will be equipped with 25 L of polyurethane foam (PF) warped with
plastic material randomly distributed in the whole reactor and ligand was prepared as
follow : 1)Tartaric acid was boiled in methanol for 1h add Five drops of Conc. H2SO4
were added, and reflux was contusions to 3h. 2) 1, 2- phenelyene diamine was added.
The solution was reflux with stirring for 3h. Cool to room temperature until a brown
precipitate is formed. The physic-chemical measuring of raw wastewater, primary
Effluent of DHS and their heavy metal at the condition:
A- At retention time 3h in absence of chelator.
B- At retention time 3h in the presence of 0.3 gm of chelator.
C- At retention time 3h in the presence of 0.6 gm of chelator.

-bis (2-aminophenyl)- 2,3- dihydroxy succinamide and its Metal
complexes have been synthesized by element analysis IR, UV-VIS spectra, magnetic
moment and conductance. Evaluate the pH, Temp,NO3,NO2 and fecal coilform
removal at different HRT’s in DHS system treating groundwater. The aim of DHS
system was achieved to produce suitable water for safe use for drinking purposes.
Based on these results observed that,
A- At retention time 3h in absence of chelator.
The experimental data showed that, The removal efficiency of TDS was
(27.11±12%).the removal efficiency of NO2 and NO3 (18.2±5%) and (15±5%)
respectively.
B- At retention time 3h in the presence of 0.3 gm of chelator.
The experimental data showed that, The removal efficiency of TDS was (48±12%).the
removal efficiency of NO2 and NO3 (30.2±5%) and (47±5%) respectively.
.
C- At retention time 3h in the presence of 0.6 gm of chelator.
The experimental data showed that, The removal efficiency of TDS was
(75.11±12%).the removal efficiency of NO2 and NO3 (62±5%) and (72%) respectively.
