“…In Malaysia, palm oil millers use ponding systems to treat POME where N and P are removed by nitrification-denitrification and precipitation with metal salts, respectively. This step of nutrient remediation could be simplified using microalgae as those nutrients are assimilated by algal cells for their growth (Kamyab et al 2016;Cheah et al 2018). In addition, nutrients such as nitrate and ortho-phosphates that are not fully removed during anaerobic digestion can be treated in microalgae pond (Kamyab et al 2018).…”

The discharge of palm oil mill effluent (POME) without effective treatment is highly toxic to the environment and receiving waters due to its high chemical oxygen demand , biochemical oxygen demand and increased levels of suspended solids. The ponding system is regarded as a conventional method for the treatment of POME but requires long retention time and extensive treatment areas. Other processes, such as physicochemical treatment, have also been applied as tertiary steps to ensure lower toxicity of the POME discharge. More recently, phycoremediation, a new biological treatment method using microalgae, has been reported as having great potential in being a highly efficient method of reducing the environmental impact of POME. This paper discusses the feasibility of the above treatment methods of POME, including the potential of phycoremediation, with a focus on their application in South East Asia.

“…Microalgae naturally exist in many palm oil mill processes, phenomena known as "algae bloom," hence declining the water quality. Because POME consists of large amount of organic compounds and inorganic compounds which is hazardous to environmental health, microalgae have been suggested as a potential candidate to remove these pollutants and able to breakdown the organic compounds present in it [37,38]. Alternatively, culturing microalgae in wastewater offers an economy, which is alternative to the traditional types of wastewater treatment [39,40].…”

“…Alternatively, culturing microalgae in wastewater offers an economy, which is alternative to the traditional types of wastewater treatment [39,40]. In the meantime, microalgae can apply the nitrogen and phosphorus compound in wastewater to produce microalgae biomass for various kinds of lipid generation, which can serve as a substrate for biofuel production [38,41].…”

In recent decades, Malaysia has been known as one of the world's leading producers and exporters of palm oil products. Every year, the number of palm oil mills increases rapidly, thus increasing the capacity of fresh fruit bunch waste or effluent discharge. Based on the data from the Malaysian Palm Oil Board in 2012, Malaysia produced 99.85 million tons of fresh fruit bunch (FFB) per year. However, about 5-5.7 tons of water was required in order to sterilize the palm fruit bunches and clarify the extracted oil to produce 1 ton of crude palm oil resulting in 50% of the water turning into palm oil mill effluent (POME). POME is one of the major environmental pollutants in Malaysia. The characteristics of POME and its behavior, if discharged directly, in water are described in this chapter. The suspended solid and nutrient content in POME could be able to support the growth of algae. This chapter aims to demonstrate that POME could be used as a main source for algae production, and this effluent is one of the main environmental problems in the tropical region especially in Malaysia.

As an important way to promote economic growth and to improve ecological environment quality, industrial agglomeration strategy has been widely accepted and implemented in various regions of China. In theory, industrial agglomeration is conducive to reducing pollution emissions. However, this needs to be tested in reality. The purpose of this paper is to test the impacts of manufacturing industry agglomeration on the quality of water ecological environment in 17 prefecture-level cities downstream of the Three Gorges Dam. Therefore, a theoretical model was established to test the direct and indirect effects. Empirically, results show that the direct effect of manufacturing agglomeration on the quality of water ecological environment is −0.426, which provides statistical evidence for the important role of manufacturing agglomeration in improving the quality of water ecological environment. The indirect effect of manufacturing agglomeration on ammonia nitrogen (NH3-N) is 0.118% through technological innovation, the indirect effect on NH3-N is 0.114% through economic growth, and the indirect effect on NH3-N is 0.254% through industrial structure. Due to the low overall level of the manufacturing industry and its reliance on dirty technologies, the indirect effects of industrial agglomeration are not conducive to improving the quality of the water ecological environment. Therefore, it is necessary to establish a long-term mechanism to promote the evolution of the regional economy along a path that is conducive to the improvement of the water ecological environment.
