Diatomaceous Earth Filter Equipment: Choosing The Right Solution
Diatomaceous earth filter equipment is a precision filtration system that uses diatomaceous earth as the core filter medium, widely applied in food and beverage, pharmaceutical, chemical, and water treatment industries. Working Principle of Diatomaceous earth filtration Pre-coat Formation A layer of diatomaceous earth (typically 1-3mm thick) is pre-coated on the filter elements (filter plates/candles) to form an initial filtration layer. Dynamic Addition (Body Feed) Trace amounts of diatomaceous earth (called “filter aid”) are continuously added to the liquid during filtration to renew the filter cake layer and prevent clogging. Sieving and Adsorption When liquid passes through the porous diatomaceous earth layer, suspended particles are mechanically retained (sieving effect) and adsorbed (captured by the charged surface of diatomaceous earth). Advantages and Applications of Different diatomaceous earth filter Types Horizontal Plate diatomaceous earth filter Incorporating Swiss and Italian filtration technology with German manufacturing processes, this equipment features long filtration cycles, high efficiency, stable filtration quality, minimal filtrate loss, high automation, and comprehensive configuration. Primarily used for clarifying liquid products including baijiu, fruit wine, beverages, soy sauce, vinegar, pharmaceuticals. Candle Filter Featuring fully enclosed design and automatic control, this equipmen offers multiple cake discharge options (dry cake discharge or thick slurry recovery). Capable...
