Frequently Asked Questions
How much wash water can the system recycle?
The system is designed to recycle up to 80% of the water used for washing back into the PET bottle washing line. Actual recovery depends on feedstock contamination, evaporation losses, and how dirty the incoming bottles are — heavily soiled material typically requires more fresh-water makeup.
How does the water filtration system work?
It filters the wash water coming off the PET bottle washing line and returns the cleaned water to the process, closing the loop. The system is engineered specifically around the flow rates and contamination profile of ASG’s washing line, so filtration stages match what the line actually produces.
Why recycle wash water instead of discharging it?
Recycling up to 80% of wash water sharply cuts fresh-water consumption and wastewater discharge, which lowers utility bills and eases environmental permitting. It also stabilizes the wash process, since returned water is already conditioned for the line rather than varying with the municipal supply.
What happens to the remaining 20%?
The balance is lost to evaporation, moisture carried out with the washed flakes, and the concentrated sludge or reject stream removed by the filtration stages. That reject stream is far smaller in volume than discharging the full wash flow, making disposal or further treatment much cheaper.
What maintenance does the system need?
Filtration stages must be cleaned or replaced on a regular schedule, and operators should monitor water quality in the return loop. As with any wash-water circuit, keeping up with filter maintenance protects both the recycling rate and the downstream washing equipment.
Can this system be added to an existing washing line?
It is designed specifically for ASG’s PET bottle washing line, so integration is straightforward on new builds. For retrofits, the engineering team can assess your line’s water flows and layout to determine how the filtration system ties into your existing tanks and plumbing.
