An ash-slurry geotextile bag PAM RFQ should cover the combined slurry, chemical and fabric system. A polymer that produces clear water in a jar may not give acceptable drainage or solids retention through the selected material. Buyers need evidence from the proposed bag system and a plan for the filtrate, not two separate quotations that assume the other component will solve the problem.
Describe the solids and handling duty
Identify whether the feed comes from a settlement basin, cleanup wash water or another contained process. Record ash, mineral and organic contributions where known, together with solids concentration and pumping requirements. Do not assume that polymer treatment changes the waste status of the collected material.
Request candidate grades from Xinqi Polymer using this feed description. Anionic PAM information may support a mineral-rich shortlist; different concentrated sludges can require a separate assessment. Any alternative chemistry needs the same environmental and product review rather than automatic acceptance.
Test with the intended fabric
Ask the bag supplier for a suitable bench or pilot method using representative slurry and the proposed fabric. Record untreated performance and candidate dose response, filtrate quality, drainage and solids retention. Keep the preparation recipe, mixing and observation period constant enough to make comparisons meaningful.
Assess whether promising early drainage persists as solids accumulate. A short clean-filtrate interval may not represent the loaded system. Include the operating limits and filling guidance supplied by the equipment provider; chemical selection does not authorise improvised filling pressures or supports.
Account for collected liquid and solids
Specify containment beneath the system and the approved route for filtrate. Clarify who provides monitoring and decides whether liquid can be reused, retreated or released. Include removal of the dewatered contents and used bag material in the scope, rather than leaving an unspecified disposal obligation at the end of the project.
Compare complete usable capacity
Evaluate chemical use, bag demand, operating time and waste handling against the amount of solids successfully managed. Separate laboratory screening from field acceptance. A complete purchase connects the accepted polymer, fabric and feed range with documented responsibilities for installation, operation and closure.
Connect the offer to the operating evidence
Review Ash-Laden Runoff Sludge Dewatering After Emergency Treatment for the related field or process question. Include those conditions when requesting product information or a quotation, and agree the evidence required before releasing a routine order.
