Reverse Osmosis Desalination

According to the energy consumption status and characteristics of high pressure pump in Seawater Reverse Osmosis desalination unit of 2500m3/d and 5000 m3/d capacity, reasonable types of high pressure pump were chosen. Research on improving the efficiency of the two types of high pressure pump was made. Without affecting the pump reliability, structural optimization was made centering a round improving the energy efficiency or making efforts to improve energy efficiency. CFD technology was adopted in the fluid end design of the reciprocating pump and high efficiency hydraulic model chosen of the multistage centrifugal pump. For multistage centrifugal pump, several hydraulic models with good hydraulic characteristics were chosen. Numerical method was used in the performance prediction and modeling. Test results show that the optimized reciprocating pump efficiency reaches 93.36% and the multistage centrifugal pump efficiency reaches 80%. This research provides theoretical guidance for reducing energy consumption of Seawater Reverse Osmosis (SWRO) and improving the efficiency of high pressure pumps.

Aplikasi teknologi membran terutama membrane reverse osmosis lebih banyak digunakan untuk penyediaan air bersih. Sumber air yang layak dijadikan bahan baku adalah air payau dengan kandungan salinitas sekitar 1.000-10.000 ppm. Kelayakan dari pengolahan air payau lebih kepada sistem desain proses desalinasi. Tujuan dari penelitian ini untuk mengetahui pengaruh keterbatasan panjang ruang sistem desain desalinasi BWRO terhadap proses dan karakteristik produk yang dihasilkan. Penelitian disimulasikan menggunakan software CSM PRO 5,  kapasitas instalasi 500 m3/hari, dan recovery 75%.  Hasil penelitian menunjukkan bahwa terbatasnya panjang ruang, sistem desain dapat dirubah dari single stage ke double stage yang akan berdampak kepada besarnya tekanan High Pressure Pump (HPP) dan konsentrasi produk yang dihasilkan.

The Relationship

In order to reduce the investment cost and energy consumption of high pressure pump in Seawater Reverse Osmosis desalination project, a new type of multistage high pressure centrifugal pump with two ends of water-lubricated bearings supporting and axial suction was proposed after analyzing the structural feature of the high pressure pump. The numerical simulation method and mesh quality was improved, the pump performance was predicted and optimized. The relationship of the critical speed and logarithmic decay rate with stage was analyzed, and the relationship between the stage and efficiency of multistage pump was combined to analyze the optimal selection for the impeller stages of multistage pump. The experimental results of axial thrust were used to modify theoretical formula of axial thrust and accurately predicated the axial thrust at different operating conditions. A new balancing device with less leakage fluid, high balancing sensitivity and proper restoring force was designed to improve the reliability of axial thrust balancing device. The experimental results show that the efficiency of the new multistage high pressure centrifugal pump is 83.07% which is increased by 3.07 percents when the design flow rate is 220m3/h, and total Head is 620m. The new multistage high pressure centrifugal pump has been applied in the Chinese Zhoushan seawater desalination project, which runs with high efficiency and stability.
