WATER & WASTEWATER ASIA July / August 2018 76 F I RS T L I NE i s a l ead i ng F i b reg l ass Reinforced Plastics (FRP) pressure vessel and cartridge housing manufacturer with over 50 years of experience in FRP pressure vessel eng i neer i ng. I t has recently supplied 406 pieces of First Line FRP pressure vessels to Shangdong Bohui Pa p e r wa s t ewa t e r recycling and zero liquid discharge project with a 30,000 m 3 /day capacity. It is considered one of the largest zero liquid discharge projects in the market and is successfully in operation since March 2018. The 406 pieces of First Line FRP pressure vessels consisted of 126 pieces from the F80-1800S-7 model (8-inch diameter, 7 element long, 1800psi) and 280 pieces from the F80-1200S-6 model (8-inch diameter, 6 element long, 1200psi). With an engineering team from the prestigious Harbin Institute of Technology, First Line has been focusing on research and development of high polymer materials, pressure vessel structure and resin system design. Over the years, First Line has developed into one of the largest ROpressure vessels and cartridge housings producer in China, with accredited certifications from ASME, NSF, ISO9001, SGS and CE. First Line has delivered over 300,000 pressure vessels to more than 32 countries, supplying to major industries such as power generation and electronics as well as for municipal sectors such as water and wastewater First Line Pressure Vessels EuroTec Cartridge Filters treatment applications. C o m m i t t e d t o innovation & excellence, First Line undergoes r i g o r o u s q u a l i t y c o n t r o l s t a n d a r d s with no compromise on high quality raw material selections and using state of the art equipment to produce RO pressure vessels, ca r t r i dge hous i ngs and cartridge filters of the highest quality. An extensive product portfolio includes: • F i r s t L i n e RO p r e s s u r e vessels come in different sizes: 2.5-inch, 4-inch and 8-inch diameters, one to eight elements long, 150 to 2000 psi operating pressure and multiple side ports of up to four ports. • EuroTec cartridge housings can house a full line of cartridge filters ranging from 20-inch to 120-inch long. They can also load multi- elements of up to 54 filters into a single housing with side and end connection type. • EuroTec cartridge filters come in both pleated & nylon filter types with 4-inch and 8-inch diameters and a rating ranging from 1 micron to 100 micron-- catering to superior high flow and backwash capabilities. • Maxflow purification system is an innovative pre-engineered smart rack system design, connecting FRP headers to the cartridge housings, hence eliminating the need of using couplings and adaptors for significant cost savings.
