Years of extensive research by Sperry testing laboratories have resulted in innovative engineering, design and manufacture of wastewater treatment/sludge disposal equipment for countless industrial applications. Their products include:
- Filter Press
- Filter Press Plates
- Sludge Dryers
FILTER PRESS
The primary application of a filter press is to separate solids from liquids. The product to be gained from the filtration process can be the liquid or filtrate (as in fabric processing), the solid or cake (as in metal hydroxide removal), or both (as in distillery applications). Regardless of application all Sperry Filter Presses are designed with three essential customer objectives in mind:
- To meet filtration requirements
- To minimize capital investment costs
- To minimize operating costs
Models include:
- Model 1200mm Fully Automatic Filter Press
- Automatic Press
- "E" Press
FILTER PRESS PLATES
Plate configuration--the selection of the correct filter element--is absolutely critical to filtration applications. Among determinant factors in plate configuration are cake thickness and filtration area, the temperature of the filtrate, the need for temperature control, volatility of the filtrate, viscosity, and so on.
Models include:
Flush Plate and Frame
When the central application is clarification of the filtrate, flush plate and frame is the configuration of choice.
Recessed Plates
When cake is the desired end-product, recessed plate configuration is generally used.
Leakproof Plates
Leakproof plates are a special gasketed type of recessed plate. Imperative in the filtration of volatile or hazardous materials, they are often used to reduce product loss or simply to effect a cleaner environment.
Lug-Style Plates
Lug style plates are used when the application demands frequent changes of filter media, and minimize labor in that they eliminate problems of media alignment.
SLUDGE DRYERS
Models include:
Sperry's SPERRYMAX(r) Filter Press Sludge Drying System
Sperry's SPERRYMAX(r) Filter Press Sludge Drying System eliminates secondary operations and product variations with repeatable moisture levels from cycle to cycle. Pathogens, air pollutants, and disposal costs are greatly reduced, and rapid heat transfer rates reduce the drying cycle.
Sperry's HYDRYMAX(r) Sludge Dryers
Sperry's HYDRYMAX(r) Sludge Dryers are designed to meet your needs. Waste solids are reduced to a powder dry residue. Complete dehydration results in bulk weight and volume reduction of 75 percent and more. Immediate substantial savings are realized through lower disposal/handling costs. Additional long term benefits can be realized through reduced RCRA liability/responsibility. Minimum controls required.
