Moringa oleifera (MO) is a multipurpose tree with considerable potential and its cultivation is currently being actively promoted in many developing countries. Seeds of this tropical tree contain water-soluble, positively charged proteins that act as an effective coagulant for water and wastewater treatment. Based on this, water quality of ''Sungai baluk'' river was examined before and after the treatment using MO seed. MO seed exhibited high efficiency in the reduction and prevention of the bacterial growth in both wastewater and ''Sungai baluk'' river samples. The turbidity was removed up to 85-94% and dissolved oxygen (DO) was improved from 2.58 ± 0.01 to 4.00 ± 0.00 mg/L. The chemical oxygen demand (COD) and biological oxygen demand (BOD) were increased after the treatment from 99.5 ± 0.71 to 164.0 ± 2.83 mg/L for COD and from 48.00 ± 0.42 to 76.65 ± 2.33 mg/L for BOD, respectively. Nevertheless, there was no significant alteration of pH, conductivity, salinity and total dissolved solid after the treatment. Heavy metals such as Fe were fully eliminated, whereas Cu and Cd were successfully removed by up to 98%. The reduction of Pb was also achieved by up to 78.1%. Overall, 1% of MO seed cake was enough to remove heavy metals from the water samples. This preliminary laboratory result confirms the great potential of MO seed in wastewater treatment applications.

Abstract:Laundry wastewater has simple characteristics in which the detergents compounds are the main constitutes. But these compounds have adverse effects on the aquatic organisms in the natural water bodies which received these wastes without treatment. Few studies were conducted on these wastes because it represent a small part of the total wastewater generated from different human activities. Moreover, the coagulation process for laundry wastewater might be effective to remove of detergents compounds. Therefore, in the present study, the efficiency of coagulation process by using chemical (ferrous sulphate) and natural coagulants (Moringa oleifera seeds) were investigated. The raw laundry wastewater samples were collected from laundromat located at Taman Universiti, Parit Raja. The characteristics of these wastes were determined and then the wastewater was subjected for the treatment process consisted of three units including aeration, coagulation and sedimentation process. The chemical and natural coagulants were used with four dosage (30, 60, 90 and 120 mg L -1 ) and the coagulation process was carried out at room temperature (25±2ºC) for one hour. The results revealed that the laundry wastewater have high concentrations of turbidity (57.8-68.1 NTU) and Chemical Oxygen Demand (COD) (423-450 mg L -1 ) with pH value between 7.96 and 8.37. M. oleifera seeds exhibited high efficiency for removal of turbidity (83.63%) with 120 mg L -1 of dosage, while 30 mg L -1 of FeSO 4 was the best for removal of COD (54.18%). However, both parameters still more than Standard B for wastewater disposal suggesting the need to increase the period of coagulation process with M. oleifera seeds or to subject of the treated effluents for a secondary coagulation process with natural coagulant products to improve the characteristics of laundry wastewater without a secondary products as that generated with the chemical coagulants.

Abstract. The consumption of water nowadays is increasing and the wastewater from variety of industry and domestic are increasing as well. If this wastewater is being untreated, it will be wasted and the chemicals inside the water especially heavy metal are harmful to the living organism. There are few conventional method used to treat the wastewater but most of them are costly, hence, natural coagulant is introduced in this study. One of the multipurpose tree Moringa oleifera, (MO) which is environmental friendly and low cost become a choice for removal of heavy metal from wastewater. The Moringa oleifera press cake (MOPC) are able to remove the heavy metal but the removal efficiency for different metals need to be investigated. Therefore, experiment on heavy metal removal by Moringa oleifera press cake was conducted. The wastewater samples and MOPC were collected from Balok River, Kuantan and Mitomasa Sdn. Bhd, Kuala Lumpur respectively. MOPC was immersed in distilled water to remove the oil and different concentration of MOPC solution were made. Jar test were carried out with different concentration of MOPC solution. The initial and final heavy metal (Fe, Cu, and Cr) concentration were measured by Atomic Absorption Spectrometer and the removal percentage was calculated. The MOPC removed 69.99% Fe, 88.86 % Cu and 93.73% Cr at optimum concentration of 10000 ppm, 5000 ppm and 15000 ppm, respectively. The MOPC also reduced 34.94% of COD and 81.6 % of turbidity. However, BOD of wastewater increased from 9.0 ppm to 18.3 ppm. The pH values was not changed with the addition of MOPC. The removal of heavy metal was increased proportionally with MOPC concentration until optimum removal was obtained.
