Content 01For Long-Term, Reliable Use of Our Products
AMCON products are engineered with a focus on safety, performance, and ease of maintenance.
Because water treatment equipment is typically operated for many years after installation, dependable after-sales support plays an essential role throughout its service life. We are committed to helping our customers keep their equipment operating in optimum condition for as long as possible.
Sludge Treatment Equipment (Sludge Dewatering Presses, Sludge Thickeners, and related equipment)
Product Warranty
AMCON Sludge Treatment Equipment is backed by a two-year product warranty. An extended warranty of up to four years is also available as an option.
Repair & Maintenance
If equipment issues arise, we respond promptly to help minimize the impact on your operation. Our service extends beyond replacing parts. We carefully inspect sludge condition, flocculation performance, and the condition of the sludge cake, then fine-tune operating parameters on site. By listening to our customers and understanding their operating conditions, we provide engineering recommendations and technical support focused on the most appropriate solution for each application.Because maintenance work on Sludge Dewatering Presses are generally performed at the installation site, rental replacement equipment is typically not required during repair or maintenance.
*For some products, on-site maintenance may not be possible depending on the scope of work or the available maintenance space.



Preventive Maintenance Service (Fee-Based)
Routine inspection and maintenance performed at the appropriate intervals help extend equipment service life while preventing sudden declines in treatment performance. Our annual preventive maintenance service helps keep your system operating reliably and consistently.
Service Scope


The following inspections are performed once a year as part of the preventive maintenance service.
- Inspection of overall equipment operation
- Inspection of motors, pumps, and other drive components
- Operational adjustment
- Inspection of wear parts
- Performance assessment (throughput, moisture content, and solids recovery rate)
- Maintenance inspection report

Product Warranty
A one-year product warranty is provided for the following Industrial Water Treatment Equipment: sand separators, iron and manganese removal filters, rapid sand filters, activated carbon filter for dechlorination, ion exchange water softener, and activated Carbon Filtration Systems for COD Removal.
Repair & Maintenance
If equipment issues occur, we respond promptly to help minimize the impact on your operation. Our support goes beyond replacing faulty components. We assess raw water and treated water quality, review operating conditions, and evaluate the condition of the filter media to identify opportunities for improvement. Based on the conditions at your site, we provide engineering recommendations and technical support tailored to your application.
Preventive Maintenance Service (Fee-Based)
Routine inspection and maintenance performed at appropriate intervals help extend equipment service life while preventing sudden declines in treatment performance. Our monthly preventive maintenance service helps keep your system operating reliably and consistently.
Service Scope
The following items are inspected during the monthly preventive maintenance service.*The inspection frequency may vary depending on operating conditions and equipment usage.
- Filtration flow rate
- Inlet and outlet pressure
- Chemical dosing settings
- Chemical dosing pump operation
- Chemical tank level
- Residual chlorine concentration
Filter Media & Activated Carbon Replacement Service
Regular inspection and replacement of filter media and activated carbon are essential for maintaining the performance of Industrial Water Treatment Equipment. Over time, filter media gradually accumulate contaminants and deteriorate, resulting in reduced filtration and treatment performance. If left unaddressed, this may lead to deteriorating water quality, increased differential pressure, more frequent backwashing, and other operational issues.
After evaluating operating conditions and the condition of the filter media, we provide a comprehensive replacement service covering everything from filter media replacement to the disposal of used filter media.
Our Services Include

Vacuum Removal of Filter Media
Loading Filter Media
- Replacement and disposal
Service includes filter media replacement as well as the removal and disposal of used filter media. - Water quality verification
Water quality can be checked before and after replacement. - Replacement for existing Industrial Water Treatment Equipment
Filter media replacement is available for existing systems upon request. Appropriate filter media are recommended based on the raw water, application, and treatment objectives.
