从China供应商批发进口50% Liquid Aluminum Chlorohydrate Ach — FOB条款

50% liquid aluminum chlorohydrate (ACH) is a pre-hydrolysed polyaluminium coagulant supplied as a colourless, transparent aqueous solution for water and wastewater treatment. This listing from Twin International Co., Ltd. in Shanghai, China, carries CAS number 12042-91-0, HS code 3824909990, and EINECS 234-933-1, with the supplier noting conformance to USP-34 specification for the water treatment grade product. The 50% w/w concentration refers to the active ACH content, a standard commercial strength that allows direct dosing without the dissolution step required of solid alum alternatives.

The active component is a partially neutralised aluminium polymer with the general formula Al2(OH)5Cl, though commercial ACH contains a distribution of Al species ranging from monomeric to high-molecular-weight Al13 polycations. The colourless, transparent appearance indicates low iron and insoluble matter, critical for potable water applications where colour and turbidity must not be introduced. Typical manufacturing involves controlled reaction of aluminium metal or alumina with hydrochloric acid followed by partial neutralisation, with the 50% solution stabilised to prevent precipitation during storage. The supplier states applicability in municipal drinking water, urban sewage, industrial wastewater, and ancillary uses in paper, casting, and printing industries.

Buyers for this product are typically water treatment plant (WTP) operators, effluent treatment plant (ETP) managers, and industrial process engineers requiring consistent coagulation performance across variable raw water qualities. ACH offers advantages over traditional alum in cold-water performance and lower alkalinity consumption, though pH operating range and final aluminium residuals require monitoring. Trade terms, MOQ, and lead time from Twin International Co., Ltd. should be confirmed directly with the supplier, as these are not stated in the available listing data.

Twin International Co., Ltd. is located in the Jinqiao Export Processing Zone, Shanghai, China, with the registered address at No. 345 Jinxiang Road, Shanghai 201206. The supplier holds a Harbor trust tier on the platform, with a response rate of 0.00% and average response hours recorded as zero, which indicates no inquiry response data is currently available through this channel. Buyers should contact the supplier directly to assess communication reliability and commercial responsiveness before committing to orders.

The company positions itself as a supplier of water treatment chemicals, specifically offering ACH for municipal and industrial applications with stated conformance to USP-34. The listing indicates flexibility to customise specifications to buyer requirements. No information is provided about factory certification, production capacity, years in operation, or export history, and these gaps should be filled through direct due diligence. The supplier's location in Shanghai's export processing zone suggests access to port logistics, though this should be verified for bulk liquid chemical handling capabilities and hazardous cargo classifications.
