Guard Filter Systems
The complete absence of suspended solids is a fundamental requirement in a number of solid-liquid separation processes.
Particle fines can be found downstream a liquid filter due to inherent, poor solid retention or as a result of a failure or malfunctioning of the filter itself.
In order to prevent potential slippage of those particles to the next steps in the process, guard filters are most typically installed right downstream the main separation equipment.
DrM can offer various guard filter solutions either in combination with a main filter or as a stand-alone unit. Such guard filters can be backflushable metallic elements or replaceable cartridges. Based on given process conditions, such as solids load, flow rate, temperature, chemical resistance etc., DrM can evaluate both CAPEX and OPEX and propose the most economical technology.
