Product overview
Coagulants destabilise suspended colloids and dissolved organics so floc particles form and settle in clarifiers, dissolved-air flotation units and rapid sand filters. We supply two principal liquid grades for municipal potable-water plants, industrial wastewater pretreatment and process-water circuits: poly aluminium chloride (PAC) and ferric chloride (FeCl₃).
PAC is a partially hydrolysed aluminium polymer with Al₂O₃ content of 10–18% and basicity of 50–70%. It neutralises negative surface charges on clay, humic acid and micro-algae at dosages typically 30–50% lower than conventional alum, producing denser floc with less sludge volume. The liquid is straw-yellow to amber, stable for six months in HDPE storage and effective across raw-water temperatures from 4 °C upward — a key advantage over alum in cold-climate intakes.
Ferric chloride solution at 40% FeCl₃ contains 11.5% iron minimum with specific gravity 1.40–1.45. Fe³⁺ hydrolyses to form iron hydroxide floc that adsorbs colour, turbidity and phosphate. FeCl₃ is the standard coagulant for phosphorus-limited effluent discharge permits, hydrogen sulphide oxidation in lift stations, and textile or food-processing wastewater where acidic pH shift assists downstream activated-sludge biology. Both grades are produced at integrated chlor-alkali and water-chemical complexes on the Black Sea and in the MENA region.
Typical buyers include municipal water authorities tendering annual chemical supply frameworks, EPC contractors equipping new treatment trains, industrial parks dosing coagulants ahead of membrane pretreatment, and regional distributors stocking IBC parcels for service-contract maintenance. HS codes 3824.99 (PAC) and 2827.39 (FeCl₃). MOQ from 24 MT on FOB, CFR or CIF terms.

Loading ports & logistics
Liquid coagulants are corrosive Class 8 cargoes that require compatible containment and careful stowage planning. We coordinate three delivery modes matched to parcel size and receiver unloading infrastructure.
1,000 L HDPE IBC totes hold 1.1–1.3 MT net per unit and load into 20-foot containers (18–22 MT per box) or on flat-rack platforms for coastal feeder routes. Each tote is UN-certified for corrosive liquids with integrated pallet base and tamper-evident valve — the standard presentation for municipal tenders and distributor restocking from 24 MT upward.
200 L PE-lined steel drums suit plants with drum-crane unloading and limited IBC storage. Twenty-foot containers carry approximately 16–18 MT net on palletised drum stacks. Drum presentation is quoted separately from IBC pricing.
Bulk ISO tank containers with rubber or PE lining carry 20–24 MT per unit for parcels above 100 MT to large water-treatment complexes with dedicated corrosive-chemical unloading bays. FOB loading at Black Sea and MENA chlor-alkali terminals; CFR and CIF quotations add ocean freight and marine insurance. Typical lead time 10–20 days from contract execution to loading window. IMDG Class 8 documentation (UN 3264 for PAC, UN 2582 for FeCl₃) is mandatory on every consignment.
Packaging & documentation
Cargo ships in 1,000 L HDPE IBC totes, 200 L PE-lined drums or bulk ISO tanks — presentation quoted separately from the FOB coagulant price. Each lot is accompanied by a mill certificate of analysis showing active-ingredient content, basicity (PAC), specific gravity, insoluble matter and pH, plus a safety data sheet (SDS) per GHS, commercial invoice, packing list, bill of lading, IMDG dangerous-goods declaration and certificate of origin.
Third-party inspection (SGS, Bureau Veritas or equivalent) at loading can be arranged on buyer request. For potable-water applications, NSF/ANSI 60 or equivalent drinking-water chemical certification documents are available on selected PAC grades — specify certification requirement on the purchase order so the correct production line is allocated.
FAQ
When should a water plant choose PAC over ferric chloride?
PAC works at lower dosages on cold raw water and leaves less sludge volume than alum or ferric salts — preferred for potable treatment and high-colour surface-water intakes. FeCl₃ excels at phosphorus removal, hydrogen sulphide oxidation and colour reduction in industrial wastewater where acidic pH shift aids downstream biological stages. Many plants run PAC on potable lines and FeCl₃ on secondary clarifiers; we quote both grades on the same contract framework.
How are liquid coagulants shipped on export routes?
PAC and FeCl₃ move in 1,000 L HDPE IBC totes, 200 L PE-lined drums palletised into 20-foot containers, or bulk in rubber-lined ISO tank containers for parcels above 100 MT. Both products are corrosive Class 8 liquids — UN 3264 (PAC) and UN 2582 (FeCl₃) — and require IMDG-compliant packaging, placarding and compatible stainless or PE discharge fittings at destination.
What drives the indicative coagulant price per tonne?
FOB quotations reflect active-ingredient concentration (Al₂O₃ in PAC, Fe in FeCl₃), basicity index, alumina or iron feedstock cost at Black Sea and MENA chlor-alkali complexes, IBC versus drum presentation, and ocean freight to your discharge port. The USD 164–200/MT band covers current liquid-grade differentials; firm pricing is fixed at contract signing with mill certificate of analysis.
