Please describe the process that generrates this wastewater and post a lab analysis.

Hello Orlando ..

the source of water is due to a buffering process carried out to cation exchange  Ca++ with K+ in a natural grow Medea.

Ca++ is introduced as Ca(NO3)2 . Pls check the results of the analysis.

 Conductivity:4800MicS/cm

COD:  1150

BOD:125

pH5.5-6.5

Chlorides659

Other parameters (Minerals, etc):

Nitrate as No3 : 1100 - 1750 mg/l
Nitrite as No2 : 30 - 60 mg/l

Our objective:  To remove NO3- to 30ppm or closer.

Discharge limits to achieve,

COD 400ppm / BOD 250ppm / NO3- 30ppm /
Cl- 600ppm ( as CL ) / Conductivity 2250MicS/cm
