Environmental Load-Out Systems

As biosolids use and disposal alternatives evolve and grow in economic benefit, Storage and Loading Systems are increasingly a key process in the Sludge Treatment phase of a plant. Highly automated, enclosed Storage and Loading Systems are very efficient in terms of operations staffing and haulage equipment utilization. Direct contact between operations personnel and potentially unsafe bulk materials is reduced or eliminated. Totally enclosed Storage and Loading Systems improve plant air quality and reduce odor emissions. Process flexibility to Sludge Treatment and disposal is created with innovative control systems which positively impact capacity requirements for costly processing equipment.

KWS Environmental has developed a line of Storage and Loading solutions for any plant size and budget and can work with customers to develop an economical solution for specific operating circumstances (e.g. haulage costs, hauler equipment type and load capacity, desired load times, goals for extent of operator involvement during loading, etc).

Industry Solutions
Environmental Load-Out Systems - KWS Manufacturing

1 – Single Conveyor

A common application for disposal of sludge and grit/screenings is loading residuals into dumpsters or trucks for haulage to disposal. For many applications, a single inclined screw conveyor is a cost-effective and maintenance-free solution.

5 – Pivoting Distribution Conveyor Arrangement

A common application for disposal of sludge and grit/screenings is loading residuals into dumpsters or trucks for haulage to disposal. For many applications, the use of a pivoting screw conveyor for loading dumpsters or trucks is advantageous when compared to other conveying technologies.

6 – Live Bottom Storage Arrangement

Larger plants produce a high volume of residuals that may require temporary storage before load out. Temporary storage allows the system to operate while awaiting trucks or dumpsters to be positioned. For many applications, the use of a storage hopper with live bottom is advantageous compared to other loadout technologies.
