“…Around 90% of TSS removal had been obtained throughout the model operation time. This is consistent with other researchers' results [11,15]. The same mechanism of TSS removal could be considered for turbidity contaminant remediation.…”

Ramadi is one of the Iraqi cities which doesn't have a WWTP. The generated domestic wastewaters are treated by the individual septic tanks. Hence, most domestic wastewater is percolating into the subsurface water and groundwater causing their pollution. The tragedian water shortage scenarios predicted by other studies have motivated the looking for new water resources. The reuse of treated wastewater is one of these alternatives. Therefore, this study tries to investigate the feasibility of using such a cheap and easy controlled technique as a horizontal subsurface flow (HSF) for treating wastewater. A lab-scale reactor has been built up from acrylic, one half of its height was filled with soil that has been collected from a selected region. The reactor was charged with wastewater using batch feeding (30 L each run) and the study lasted for 3 months with an average of one run weekly including the acclimatization period. Results revealed the fairly contaminants’ removal, where the average removal efficiency of COD, BOD5, and TSS were 76%, 73%, and 90%, respectively. In conclusion, the HSF is a reasonable, low cost, less complicated treatment technology that could be adopted as an alternative water resource for irrigation of the green belt.

“…Green campus campaign has been introduced in NDUM campus as one of efforts to support sustainable development goal set by United Nation. Several studies have been performed to identify the potential of natural and environment resources in NDUM campus for further action including wetland [10], recycle waste [11], solar energy [12] and other study related [13].…”

Water has become a necessity in our daily life. The impact of unsafe water on the consumer is critically alarmed and has contributed human health problem. An alternative clean water sources as a water supply should be sustainable solution to overcome this problem. Malaysia is located at the equator to have rain and hot weather along the year. Therefore, the possible use of spring water as an alternative clean water source will improve the quality of water consumption especially for small community in rural area. The aim of this study is to investigate the performance of spring water sources located in National Defence University of Malaysia (NDUM) campus to support the Green Campus champaign. The spring water analysis was performed for various physicochemical during February 2020. Temperature, pH, electrical conductivity, total dissolved solid, total suspended solid and dissolved oxygen were measured to generate water quality index. The results demonstrated the water samples were found to be suitable for use were within permissible limits except pH were close to or exceeded the permissible limit of standards, which indicates that requirement of treatment prior to use. The outcome of this study may contribute to propose the new way of monitoring water quality in campus by using real-time system. In addition, the outcome also to provides the baseline information about water quality for the welfare of society, support the green campus campaign and that may also help in future water security and sustainability planning for the NDUM campus area.

“…Meanwhile, the optimum growth temperature for water lettuce was 21-30• C [5]. The temperature taken is in the range of a relevant temperature for plant-microbe growth in between 20-30 o C in the temperate regions [6]. Water lettuce and water hyacinth were cultivated in water culture at various pH values.…”

A man-made system that mimics the function and structures of natural wetlands is called constructed wetlands. It is able to treat sewage water with low technology, low energy requirements, affordable and easy to maintain. However, how it works in tropical climates is still unknown and there is a need to figure out the sustainability of floating plants in treating domestic sewage. This study aims to investigate the pollutant removal efficiency of two selected floating plant species, water hyacinth and water lettuce, in treating domestic sewage. The growth rate of both plants will be examined for the best-recommended plants in the constructed wetland systems for domestic sewage treatment. The data was collected through a pilot-constructed wetland in the USM, Engineering Campus that is integrated with two species of floating plants: water hyacinth and water lettuce. The parameters studied were chemical oxygen demand (COD), total suspended solids (TSS), and ammoniacal nitrogen (AN). The findings reveal that the removal efficiency of water hyacinth is higher for COD and TSS at 40.96 % and 43.94 % respectively compared to Water Lettuce with 26.86 % for COD and 17.79 % for TSS. However, Water Lettuce has a slightly higher removal efficiency of NH3-N at 26.52 % compared to Water Hyacinth at 24.35 %. In terms of growth rate, Water Hyacinth is lost to water lettuce, but they have higher biomass to uptake nutrients with just a small increment of area coverage. Therefore, water hyacinth is favourable to implement in floating plant-constructed wetlands as it needs less maintenance than water lettuce to achieve discharge with standard A for TSS and COD and standard B for NH3-N based on Malaysia Wastewater Effluent Discharge Standards.
