Hello  Thank you, for ​the suggestion ​ ​​please check ​​​the flowing , ​​​which may be ​​​useful ​ ​ ​ the source of ​​​​water is due ​​to ​​a ​​buffering ​​​​process carried ​​​​out to ​cation ​​​​exchange ​ ​​​Ca++ with K+ ​​in ​​a natural ​​grow ​​Medea (​​Coconut ​Peath )​​ . ​ ​ ​ ​ Ca++ is ​​​​introduced as ​​​​Ca(NO3)2 . Pls ​​​​check the ​​​​results of the ​​​​analysis. ​ We have carried our trial to substitute the Ca(NO3)2. We used CaCl2 & Ca(OH)2 , but the cation exchange rate was not satisfactory. ​ In addition to ​K+ there is Ca++​ and Na+ in ​​considerable ​amounts in the effluent . ​ However pls ​check bellow ​the current ​analytical ​report. We will ​be doing a ​fresh ​assessment ​ of the ​effluent again ​with mote ​details on the ​Cations present.​ will let you ​Have that as ​well, soon.​  ​ Water volume 800-1,000m3/d​  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
