Wedgewater Polyurethane Sludge Drying/Filter Bed System

Product Description

The Wedgewater� Filter Bed System�is the result of intensive research, rigorous field testing, and years of experience in screen and filter design and manufacture. It offers highly cost-effective sludge dewatering, with significant advantages over both slow, space-consuming sand drying beds and costly, energy-intensive mechanical dewatering units.
This unique system�is composed of interlocking *2� x *2� high-density polyureth-ane filter modules. Practically indestructible, these panels shrug off the effects of sun and environment, are corrosion and abrasion resistant, nonconductive and virtually maintenance free.
Each module features �a special non-clogging orifice design, *2% open area, and�built-in underdrain which insures continuous dewatering. Integral, molded-in structural elements allow the panels to easily support small front-end loaders for sludge cake removal. The interlocking panel modules make setup and panel replacement a snap � without tools!
�All Types �of sanitary sewage and water treatment sludges are efficiently dewatered�by Wedgewater� Filter Beds. The system also effectively dewaters most biological and chemical industrial sludges. It is suited to both indoor and outdoor applications. Unaffected by wide variations in concentration, the system can dewater a 1% aerobically digested sludge one day, followed by a 5% primary sludge the next. Even the most dilute sludges can be economically concentrated.
The filtrate extracted �by the process is of a high quality, usually less than *0 ppm�suspended solids, with low BOD and COD levels. The filter panel design maintains sludge porosity, prevents media blinding and maintains filtrate drainage at the optimal rate. The high capture rate and unusually clear filtrate allow many plants to discharge the effluent directly into tertiary processes.
After dewatering,�the sludge is left suspended on a dry media. The circulation of�air both above and below the layer of sludge speeds drying. The sludge cake can then be easily removed with mechanical loaders.
