MANUFACTURER · ZHENGZHOU, HENAN, CHINA
Polyaluminium chloride and polyacrylamide for water plants, industrial effluent and mining. Grade selected from your water analysis, certificate of analysis with every batch, export packing prepared to your order.
PRODUCTS
Coagulation and flocculation are different jobs. We make both, so the two stages can be matched to the same water instead of being bought from two suppliers.
A pre-hydrolysed inorganic coagulant. It neutralises the charge on colloids and bridges them into flocs that settle quickly, without changing the pH of the treated water much.
A high-molecular-weight flocculant. Long polymer chains bridge small flocs into large, dense aggregates, which speeds up settling and improves sludge dewatering.
WHY KAIMILA
Both product lines are made in our own plant in Zhengzhou. You deal with the producer, so grade changes, packing and delivery dates are decided by the people who make the product.
Al2O3 content, basicity, pH, insolubles and moisture are tested lot by lot. The certificate ships with the goods and can be checked against your incoming inspection.
Send pH, turbidity, alkalinity, COD or fluoride level and we run a jar test to recommend a grade and a starting dose, instead of quoting a generic product.
25 kg bags with PE liner, 1000 kg jumbo bags, 25 L drums and 1000 L IBCs. Palletised or floor-loaded, with marks and labels prepared to your order.
APPLICATIONS
Eight industry groups, each with its own dosing pattern and its own failure modes.
Coagulation and flocculation for raw water clarification and for tertiary treatment of municipal sewage.
Colour, turbidity and suspended solids removal in mixed industrial effluent, including parks with multiple discharge sources.
Anionic PAM for tailings thickening and supernatant clarity; PAC ahead of it to destabilise fine clay.
Retention and drainage aids, plus white water clarification and sludge conditioning.
Decolourisation of dyeing effluent, where cationic PAM is often used together with PAC.
Produced water treatment and drilling wastewater clarification.
Clarification of process water and wash water, and dewatering of organic sludge.
Two-stage fluoride removal for battery, PV and semiconductor wastewater.
SELECTION
Most dosing problems come from using one product for the other one's job.
| Question | PAC (Coag Aqua) | PAM (Floc Aqua) |
|---|---|---|
| What removes turbidity and colour? | Yes — primary coagulant | No — works after coagulation |
| Typical dose | 10 – 50 mg/L | 0.1 – 2 mg/L |
| Main mechanism | Charge neutralisation, sweep floc | Polymer bridging |
| Feed order | First, fast mix 1–2 min | Second, slow mix 10–15 min |
| Sludge dewatering | Conditioning aid | Main reagent (cationic) |
| Overdose risk | Re-stabilisation, higher sludge | Filter blinding, viscous water |
RANGE
Standard range below. Other grades and blends can be produced to order.

| Polyaluminium Chloride (PAC) | Industrial 28 % (GB/T 22627) / drinking water 29 % (GB 15892) | Powder / liquid | 25 kg bag, 1000 kg jumbo, IBC |
| Polyacrylamide (PAM) | Anionic, cationic, non-ionic | Powder / emulsion | 25 kg bag, 750 kg jumbo |
| Defluoridation reagent | Selected per fluoride load | Powder | 25 kg bag |
| Composite carbon source | COD-equivalent blends | Liquid / powder | IBC / 25 kg bag |
HOW WE WORK
pH, turbidity, alkalinity, COD, fluoride, temperature and daily flow. A photo of the plant helps too.
We test candidate grades at several doses and send you the settling curves with a recommended starting point.
Start with a few tonnes or a pallet, run it on site, and adjust the dose with our technical team.
Fixed grade, batch COA, and a delivery schedule that matches your consumption.
Jar tests run in our laboratory on customer samples. The settling curve and the recommended dose come back with the quotation.
PAC is an inorganic coagulant. It neutralises the surface charge of colloids so that they can gather into small flocs. PAM is an organic flocculant with very long molecular chains that bridge those small flocs into large, fast-settling aggregates. In most plants PAC is dosed first with rapid mixing, and PAM is dosed second with gentle mixing.
A trial order can start at 1 tonne for powder grades, or one pallet. Full container loads are 25 tonnes floor-loaded or about 20 tonnes palletised for a 20 ft container. Mixed containers with PAC and PAM are possible.
Yes. We send 1 – 2 kg samples of the recommended grade so that you can run a jar test in your own laboratory. Please share the water analysis first, because the sample has to match the grade, not just the product name.
Commercial invoice, packing list, bill of lading, certificate of analysis for the batch, and the material safety data sheet. A certificate of origin can be added when your customs or a letter of credit requires it.
FOB Qingdao, Shanghai or Ningbo, and CIF or CFR to your port. Payment is normally 30 % deposit with the balance against a copy of the bill of lading, or an irrevocable letter of credit at sight. Production takes 7 – 15 days after the deposit, depending on grade and quantity.
Our standard range is produced to the industrial grade specification GB/T 22627-2022. If your project needs a grade for potable water supply, tell us the required standard and the destination country at the enquiry stage, and we will confirm what documentation we can provide for that order before you commit.
pH, turbidity, COD or fluoride — one page is enough to start. We reply within one working day.
