Biochar as a superior material for enhancing the performance and microbial diversity in biofilters treating greywater

Popis výsledku v původním jazyce

This research evaluated the efficiency of greywater treatment in biofilters amended by different additives: biochar (5 % and 10 % v/v), woodchips, crushed bricks, and limestone chippings. The effect of the additives on the removal of selected organic (benzotriazole, caffeine, diclofenac, DEET, methylparaben, and an anionic surfactant) and inorganic (boron, copper, nickel, and zinc) pollutants was tested. The biofilters provided almost complete removal of all organic pollutants, except for benzotriazole (38 %-49 %). This compound was 99 % removed only in biofilters with biochar. This enhanced removal stemmed from greater sorption capacity of the biofilters with biochar. The removal of metals was high (>90 %), however, boron removal was negligible. The treatment reduced the toxicity to negligible or stimulatory levels. Analysis of the prokaryotic microbiome showed a significantly greater diversity in the biofilters with 5 % biochar and with woodchips. The biochar amendment offers comparable treatment effect at both doses suggesting the application of the lower ratio in fullscale systems due to economic reasons. The use of biochar brings very important engineering added values, which are longevity and the ability to selectively retain organic contaminants, but not the nutrients. This may qualify the use of biofilters as an attractive pretreatment of greywater for irrigation purposes.
