The industrial leaf filter for chemicals has a durable and completely enclosed configuration. It is easy to automate and ensures clean operation, prevention of leaks, corrosion and operating difficulties. It provides a large filtration area for a relatively small vessel with quality filter leaves. It can be used for both primary filtrations involving high solid contents and also polishing filtration with low solids loads. It has high flow rates that requires filtration areas above 120m² but can also be used for smaller applications. Apart from chemicals it can also be used in edible oil refineries, food and beverage industries, pharmaceutical, petrochemical industry, etc.
