Abstract

The present study depended on (54) samples of water, nunicipal wastewater (39) samples Tigris river water (north, middle and south) of Mosul city (9) samples and water supply treatment plants (Al-Maa Al-Muwahad & Al-Danadan) (6) samples.
Analytical results showed the LAS concentration in nunicipal wastewater samples may vary between (0.67-2.5)mg/L and in Tigris river water (north, middle and south) was found (0.01, 0.35 & 0.9) mg/L respectively. The concentration of some heavy metals (Cu, Cr, Pb, Mn & Fe) was measured using atomic absorption spectrophotometer for the river raw water samples and water supply treatment plants samples. The removal affinity percentage of heavy metals (Cu, Cr, Pb, Mn & Fe) was calculated.
Study's results indicated decreasing in heavy metals removal efficiency with increasing in detergents (LAS) concentration in Tigris river water, this improved (LAS) acts as a dispersion factor for heavy metals in wastewater which prevents its sedimentation and removing.
In order to decrease the environmental and health dangers of detergents pollution, wastewater curing by using a special unit of treatment (suggested by the investigators) with four types of granular activated carbon (GAC) which prepared by investigators (research under edditing) as adsorbent for LAS molecules.
Study's results show the dependent method suitibility in reducing detergents pollution percentage by 84% as a maximum. The ability of LAS uptake from river wastewater by using sulfurized and phosphorized GAC obtained from Molasses was found to be (80.3-84.4%), by using sulfurized and phosphorized GAC obtained from asphalt was found to be (30-69%) at special laboratory condition (temperature 25oc and constant pH), that showed a high affinity of LAS molecules toward sulfurized GAC more than phosphorized GAC.
