Adsorption and Polishing Powdered, columnar, granular and impregnated activated carbon, ionexchange resins and specialty adsorbents. PAC and PAM are our core product focus. Grades, forms and specifications are selected for the intended application and confirmed through technical review and testing where required.

Project and Supply Support Product Selectton and Testtng We review wastewater or sludge characteristics, current product data, dosing conditions and equipment before proposing suitable grades. We support sample preparation, jar tests and comparative evaluation, with attention to dosage, effluent quality, sludge behavior and total treatment cost. PAM selection considers ionic type, charge density or hydrolysis, molecular weight and dissolution performance. Documentatton and Delivery We coordinate technical data sheets (TDS), safety data sheets (SDS), certificates of analysis (COA), product specifications, packaging information and export documents for the selected products. Supply execution includes production follow-up, inspection coordination, loading and shipment support. Product availability, documents and packing are confirmed with the selected manufacturing partner and for the destination. Supply Planning We support trial orders, routine replenishment, project purchases and alternate-source evaluation. Where feasible, an approved backup grade or source can help customers prepare for supply interruptions or urgent replacement needs. Full-container and mixed-product shipments can be discussed; mixed loading depends on chemical compatibility, transport classification, packaging and destination requirements. How to Start Share the product or application, current specification, quantity, delivery destination and required schedule. We can then discuss suitable grades, supporting documents, samples and commercial terms.
