Horizontal Belt Filters
Compositech has been manufacturing specifically designed horizontal belt filter stations in a myriad of configurations since 1991. Horizontal Belt Filters are used in applications where washing of the cake is crucial. They are widely used in the production of fine chemicals, the processing of silica and various minerals, flue gas desulfurization, phosphate rock beneficiation, and the processing of pharmaceuticals and pigments.
The horizontal belt filter is used as an extractor of moisture from a slurry. Cake washing is provided by multistage single run or counter current flood washing. The horizontal vacuum belt filter is capable of washing soluble components from the filter cake and reducing residual moisture to very low levels in the dry zone. The continual filtration process includes constant filter cloth washing to provide a clean cloth belt for every filter cycle. With this type of system, the entire process can be observed from feed to discharge. Horizontal belt filters require no tank so the inventory of the slurry is reduced to what is actually being filtered.
SL Chemifilter™ Horizontal Vacuum Belt Filter
Compositech produces a line of small and medium sized horizontal vacuum belt filters designed specifically for fine chemical filtration. Total active filtration area for our SL Chemifilter™ ranges from 2.5 to 100 square feet. These filters feature tubular frames for ease of cleaning and special chemical resistant materials are used in filter construction and for coatings. We use non-lubricated FDA approved polymer bearings, fully enclosed troughing supports, full coverage drip pans with flanged drains, and fully encapsulated drainage belts for our horizontal belt filters.
Compositech's 5500/4600 horizontal belt filters are designed for easy maintenance as the non-drive side of the frame is designed for easy removal of the drainage belt, pulleys and support decks without complete disassembly of the filter. The vacuum pan is easily accessible with a lowering mechanism. These filters are heavy duty designed for continuous operation and they can be totally enclosed for control of fumes and sprays, fitted with several cake washing options, designed to incorporate wash down systems, and fully coated with corrosion resistant materials or fitted with food-grade components as needed.
T-REX™ Horizontal Belt Filter
Our T-REX™ Horizontal Belt Filter is the largest filter of its kind. This horizontal belt filter, initially manufactured for flue gas desulphurization for TXU Energy, is a 4-meter wide modular system which can be sized and resized according to customer needs.
Each easily transportable module is 2.5 meters long and increases the filtration area by 10 square meters. To change the size of the filter, you simply add or remove modules.
