Surface water are being contaminated by various toxic elements through anthropogenic activities and natural sources between residential and premises. Studies had shown that aquatic plants had its ability to improve water quality in purifying polluted surface water. Many studies had been introduced to treat the sewerage water and had been a cost to public to pay monthly. Thus, increasing living cost after water and electrical tariff. In this study, sewerage water at urban, rural, remote or even island could possibly use some aquatic plant as alternative sewerage water treatment. The objective of the study is to identify the effectiveness level of certain aquatic species suitable for sewerage water treatment. Some aquatic plants will be used in this study to identify the level of chemical absorption from wastewater. The testing plot located in a small basin with constant, controlled water flow from the sewerage holding tank. In this study, sewerage, water from Puchong Sewerage Treatment Plant had been used as a polluted source. The water quality at each basin will be monitored and recorded daily and end at a constant reading of water quality. From the study, it was found that certain aquatic species could absorb some chemical characteristic during phytoremediation processed as founded by many previous studies nationally and internationally. The treatment of sewerage sources for this study had been deteriorated over 20% from the sewerage characteristics using different types of species. This had identified that alternative wastewater treatment using some species could possibly treated the sewerage water within a period of time. Further study could be done for improving wastewater treatment timeframe either in a different scale or in an integrated mode of treatment in order to treat others characteristics sources of wastewater.
Periorbital cellulitis is an uncommon presentation to primary care and the emergency department. With multiple aetiologies, it is crucial that an appropriate history and examination are applied to identify the primary cause and initiate therapy in a timely manner.We present a 30-year-old male who presented with recurrent periorbital cellulitis treated repeatedly with antibiotics without consideration of the origin of the infection. Subsequent investigations discovered a widely dehiscent mucopyocoele of the frontal sinus that had been unrecognised and untreated. Once identified, the patient underwent functional endoscopic sinus surgery to clear the mucopyocoele and improve the drainage of the frontal sinus. Symptoms have not recurred since the surgical intervention.A poor understanding of the aetiologies of periorbital cellulitis and the related anatomy likely played a role in his delayed definitive management. Clinicians should be aware that in a patient presenting with periorbital swelling and erythema, consideration should be given to the possibility of underlying sinonasal pathology.
Industrial wastes had contributed to environment pollution. In particular, wastewater had been increasing in any country around the world, from agricultural sectors to commercial sectors. Wastewater treatment had raised overhead costs on operational and maintenance. Many studies had been done on finding alternatives for wastewater treatment. In general, a variety of wastewater treatment processes are employed which includes primary treatment, secondary treatment and tertiary treatment. In this study, three designed systems of tertiary treatment had been observed to evaluate wastewater quality reduction. A designed system had been selected to identify the treatment efficiency using the same treatment concept of phytoremediation. There are three designs which are the large-scale design, medium-scale design and portable scale design. The differences among the designs are that the first large-scale design uses wastewater sources directed from a sewerage plant, while the second design with medium-scale uses groundwater water with nutrient loads from aquatic species. The third design with portable scale uses a customised aquarium method with conventional filtration. From the study, it was found that different solution design systems could perform treatments for different wastewater characteristics. The average range of treatment had been seen to reduce contaminated water quality between 10 to 60% on differences in water quality parameters. This identified that the constructed nature-based system (NBS) could possibly be performed as one of the wastewater treatments. Further study could be done for any sources of wastewater in future as an added value to the improvised existing design to improve surface water quality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
