Siemens Water Technologies’ Memcor CP II ultrafiltration membrane system for industrial and municipal plants reduces membrane array footprint by up to 50 percent compared to previous Memcor membrane arrays, the company says.
The modular, rack-based system is designed to lower installation and operations costs and is scalable to meet a wide range of plant capacities for new installations and major upgrade applications, according to Siemens.
Up to 28 L40N-type membrane modules constructed of durable materials and reusable housings can be combined on a single MemRack unit, which integrates feed, air, filtrate and waste headers into one assembly. The fully assembled, self-supporting racks are then manifolded together to form functional arrays. Piping connections on the ends of the racks further facilitate installation.
The company says the MemRack array’s design also optimizes hydraulics for minimal pressure loss to improve fluid distribution resulting in more stable filtration. Siemens says these arrays can fit in standard-size shipping containers for deployment anywhere in the world.
The core of the CP II system is the L40N membrane module. The L40N utilizes the latest family of Memcor ultrafiltration membrane fibers that more than double the surface area of previous Memcor modules. Introduced in 2010, the “N” fiber delivers enhanced abrasion resistance and better performance to end users, the company says.
The CP II process design shortens backwash duration compared to earlier Memcor CP units to increase system up time and productivity, Siemens says. Side and top module access points, unique to the CP II system, permit in-place service which eliminates the need to remove modules for easier maintenance.
The Memcor CP II system can be supplied as a complete system or as MemRack arrays and L40N modules only.
