The Effects of Supporting Electrolyte type and Concentration on the Phosphate Removal from Wastewater By Electrocoagulation With Aluminum Plate Electrodes

Abstract

In this study, The effects of type and concentration of electrolyte on phosphate removal from

wastewater by electrocoagulation with aluminum plate electrodes have been investigated.

Effect of supporting electrolyte type was investigated using NaCI , KCI, NaNO3 and Na2SO4. Although Na2SO4 is

optimal supporting electrolyte according to energy consumption, it is obtained higher removal efficiencies using

NaCI and KCI. It is determined optimal supporting electrolyte dosage using NaCI. Consequently, it can be said that

optimal electrolyte type is NaCI and optimal concentration is 5 mM.

Alüminyum Elektrotlar Kullanılarak Elektrokoagülasyon Yöntemiyle Atıksulardan Fosfat Giderimine Destek Elektrolit Tipi Ve Konsantrasyonunun Etkisi

Abstract

Bu çalışmada alüminyum elektrotlar kullanılarak elektrokoagülasyon yöntemiyle atıksulardan fosfat iyonlarının giderilmesinde kullanılan destek elektrolit türü ve konsantrasyonunun etkisi çalışılmıştır. Destek elektrolit tipi araştırılırken NaCI , KCI, NaNOand NaSO kullanılmıştır. Enerji tüketimi açısından NaSOen uygun destek elektrolit olarak görünmesine rağmen NaCI ve KCI ile elde edilen giderme verimleri daha yüksektir. En uygun destek elektrolit NACI ve en uygun destek elektrolit konsantrasyonu 5 mM olarak tespit edilmiştir
