Investigation of the influence of <i>Ceratophyllum demersum</i> to refine diluted compost latex

Abstract

ABSTRACT:Water pollution has always been a major problem in the environment. Polluted water is harming for human health and need to clean water from pollution factors. One of the economic and rapid methods for elements removal is displacement metals by biosorption. The purpose of this study was refining diluted compost latex by Ceratophyllum demersum that was diluted 200 times with distilled water. Diluted compost latex (DCL) accompany with aquatic plant Ceratophyllum demersum was located in bottles which were 6 liter in four replication. The experimental performed at the open air of Khorasgan (Isfahan, Iran) University area for 18 days without aeration. Result of Chemical oxygen demand (COD) indicates that the COD was decreased from 728 mg/L to 189.5 mg/L. Also, this investigation was demonstrated that the amount of ammonium in diluted compost latex was decreased from 60 meq/L to 13.33 meq/L. The amount of nitrate in diluted compost latex has decreased from 90 meq/L to 26.66 meq/L, and the amount of Phosphorous was declined from 1.2 meq/L to 0.21 meq/L. EC of diluted compost latex was reduced from 1.02 ds/m to 0.74 ds/m. All of the consequences which were mentioned indicated that this aquatic plant (Ceratophyllum demersum) is one of the best natural ways to refine Polluted water. @ JASEM

Phytoremediation of Physico-chemical Parameters in Wastewater Effluents from Car Wash Bays in Yenagoa Metropolis, Nigeria

“…Meanwhile the measured DO in the L. Minor treated wastewater sample was lower than the findings reported by [34] in their study of the use of duckweed in the treatment of wastewater from washing of Sisal fiber. The increased percentage values of DO concentration in C. Demersum treated wastewater sample confirmed the findings of [32]. More so, the increase in the level of DO in the E. Crassipes treated wastewater sample was lower than the percentage values achieved by [30].…”

“…More so, nitrate bioremoval efficiency of E. Crassipes observed in this study was higher than the findings reported by [31], [25]. The nitrate removal efficiency of C. Demersum was in consonant with the findings of [32].…”

Treatment of leachate solid wastewater and protein-rich biomass production using Ceratophyllum demersum (Linnaeus, 1753)

“…18 The NH4±N value in our study decreased from 476.2 mg/L to 18.03 mg/L. Foroughi 17 reported that the NH4±N concentration in wastewater decreased from 60 mg/L to 13.33 mg/L within approximately six days, and Foroughi et al 15 found a reduction in NH4±N concentration from 135 mg/L to 29.16 mg/L. All these studies observed a decrease in NH4±N concentration after treatment.…”

“…15 There are numerous studies on the use of C. demersum in wastewater treatment. [15][16][17][18][19][20] The present study aimed to determine the treatment efficiency, growth performance, and protein values of the biomass obtained through the phytoremediation method using Ceratophyllum demersum with municipal leachate wastewater.…”

Bacterioplankton from Two Hungarian Danube River Wetlands (Beda-Karapancsa, Danube-Drava National Park) and its Relations to Environmental Variables

“…Macrophyte cover in %, the highest in summer in MDU, was related positively to the temperature (R Sp = 0.48), negatively to TN (R Sp = -0.55) and conductivity, but very weak negatively only to the quantity of the attached bacteria (r = -0.18, p = 0.17, not significant). Ceratophyllum demersum increases the dissolved oxygen and decreases COD and the pollution in the water and can be an effective biosorbent for phosphorus, ammonium and nitrate (Foroughi, 2011). Most probably such processes might have happened in Riha oxbow with dominance of this macrophyte species, reflecting with lower bacterioplankton development.…”
