“…used in the present study is more than that reported in the literature. Gani et al [7] revealed that B. braunii reduced BOD, COD and TN in the greywater in Malaysia by 82, 88 and 52%, respectively, as well as the resulted reported by Gokulan et al [29] who found that Botryococcus sp. reduced BOD and COD in greywater from Men hostel by 66.7 and COD 85.6%, respectively.…”

“…Conversely, utilization of ammonia is associated with the releasing of [27]. The reduction obtained here is more than that reported by Gani et al [7], where the maximum reduction of TN from household greywater in Malaysia by B. braunii was 52%. These differences might be due to the starvation process conducted in the current work which induced the microalgae growth and thus the reduction efficiency.…”

“…The main consideration in the phycoremediation process is to use indigenous strains which have the ability to survive and compete with other indigenous microorganisms in the greywater such as bacteria. Botryococcus braunii, Scenedesmus dimorphus, Spirulina sp., Chlorella vulgaris and Phormidium sp., have high effectiveness because they have the ability to tolerate hard environmental conditions [7]. One of the effective techniques to improve the phycoremediation efficiency is using starved microalgae, in which the activated algae is obtained from the sludge thickness stage where hyper-concentrated algal cultures are available, and then subject to the starvation process by the drying at room temperature.…”

The present study aimed to investigate the potential for application of phycoremediation system using Botryococcus sp. for the treatment of bathroom greywater at village houses. The greywater samples were obtained from four houses. The treatment system was conducted at ambient temperature for 21 days. Botryococcus sp. (Accession No. JQ585723.1) was inoculated into the greywater in a dry mass (0.3 mg L -1 ). The results revealed high effectiveness of the treatment system. The maximum reduction of biological oxygen demand (BOD 5 ) from four types of greywater ranged from 85.3 to 98%, while was between 71.22 and 85.47% for chemical oxygen demand (COD) after 21 days. The reduction of nitrate (NO 3 -) appeared rapidly within 18 days of the treatment period with 98% of the reduction efficiency. Reduction of ammonia (NH 3 ) and orthophosphate (PO4 3-) was recorded after 21 days with the efficiency ranged from 86.21 to 99 and 39.12 to 99.3%, respectively. The high removal percentage of potassium (K) (97%) recorded within 3 days, while calcium (Ca) reduction (95%) was noted at the end of the treatment period indicating the high applicability of phycoremediation system to be used in the village houses. Moreover, the system is easily implementable, very low cost where no energy is required, eco-friendly and has no toxic by-products.

The performance of Scenedesmus sp. in the phycoremediation of domestic secondary effluents and the high-quality production of the effluents for safe disposal are investigated in the current work. An indigenous strain of Scenedesmus sp. is obtained from a sludge thickness basin at a wastewater treatment plant. The characteristics of this microalgae are identified using a molecular analysis based on 18S ribosomal RNA sequences. The phycoremediation process is conducted in a photoreactor tank (5 L) with five different concentrations of Scenedesmus sp. (between 10 5 and 10 6 cells mL À1 ). The reactors are then placed outdoors (exposed to natural environmental conditions) for 8 days. The Scenedesmus sp. had the ability to remove 91.86%, 98.15%, and 93.11% of total nitrogen (TN), total phosphorus (TP), and total organic carbon (TOC), respectively, and reduce biochemical oxygen demand (BOD), chemical oxygen demand (COD), and total suspended solid (TSS) by 86.5%, 69.9%, and 76%, respectively, at a concentration of 10 6 cells mL À1 . Moreover, the increase in the pH value during microalgae activity contributed to the increases in nutrients and characteristics percentage removal. The treated secondary effluents generated from the phycoremediation process after 8 days met the EQA 1974 (Regulation 2009) sewage sludge (standard A) in terms of TN and TP but is still not under the permissible limits for BOD, COD, and TSS. In conclusion, an indigenous Scenedesmus sp. is efficient in enhancing the quality of secondary wastewater to meet the standards required for reuse or safe disposal.

“…This sustainable technique had been applied and studied widely using different type of wastewater such as domestic wastewater, greywater, dairywater, piggery wastewater and textile wastewater [12]. Microalgae growth is able to remove phosphorus and nitrate while able to present itself as an alternative to avoid water contamination [13].…”

Abstract. The common sources of water pollution in Malaysia are domestic sewage and industrial waste. Therefore, domestic wastewater quality effluent should be improved before discharged through the outlets. The alternative method of treatment uses microalgae for water remediation which is known as phycoremediation was applied. This technique is to remove or reduce nutrients and harmful pollutants in domestic wastewater. Thus, objective of the present study is to bioremediate the physiochemical and heavy metal from domestic wastewater using freshwater green microalgae Botryococcus sp. A photobioreactor is used to treat the wastewater by employing the microalgae Botryococcus sp. as a vital part of the treatment system. The results show that several nutrients have been reduced successfully such as phosphate and total phosphorus of 100% removal, inorganic carbon of 99% removal, total carbon of 42% removal, and nitrate of 10%. The most prominent heavy metal content that has been removed is Aluminium of 41%. At the same time, the growth of microalgae Botryococcus sp. in this wastewater has achieved the maximum value at Day 4 with 2.58 x 10 5 cell/ml only. These results show the potential of Botryococcus sp. cultivation as an alternative method to treat domestic wastewater and any other biotechnology works in the future.
