Products & Services
Seven product lines, from coagulation to lake restoration
We match the chemistry to the water, not the other way round. Any grade below can be quoted together with a jar test report on your own sample.
02Flocculant
Cationic Polyacrylamide (CPAM)
Charge density from 10% to 60% for organic sludge. Cake moisture below 60% on belt presses, centrifuges and screw presses, with flocs that resist shear.
Technical data →03Coagulant
Polyaluminium Chloride (PAC)
High basicity inorganic coagulant working across pH 5.0–9.0, including cold low-turbidity water. Fast floc formation and short settling time.
Technical data →04Decolorant
Decolorizing Flocculant
Captures the chromophores of reactive, acid and disperse dyes as well as lignin. Colour removal above 95%, with COD and turbidity reduced in the same step.
Technical data →05Defluoridation
Fluoride Removal Agent
Holds effluent fluoride below 0.5 mg/L from feed concentrations of 10 to 2000 mg/L, with about 40% less sludge than lime precipitation.
Technical data →06Restoration
River & Lake Remediation Agent
Mineral-based in-situ treatment for black-odour water bodies and contaminated sediment. Visible improvement in colour and odour within 48 hours.

Every formula starts with a real sample of your water
Why Zhengjia
We sell the result,
not the drum
The same chemical dosed differently can double your cost per cubic metre. We test first and quote second, so what you buy is a working dosage, not a guess.
Free jar test on your sample
Send 2–5 L of water or a sludge sample. A bench report with chemical combination, dosage and expected outlet values comes back within five working days.
Dosage design and commissioning
Make-up concentration, dosing point and control range are set against your plant — on site or by remote support — until the outlet runs stable.
Export documents, OEM and stable supply
COA, MSDS, TDS, packing list and certificate of origin with every lot. Private label, custom bag design and mixed containers on request.
Export & OEM
Built for buyers outside China
From bag design to the bill of lading, the shipment is prepared the way an importer needs it — not the way a domestic order is packed.
Packaging
- 25 kg PE-lined PP woven bags
- 750 kg jumbo bags
- 200 L drums / 1000 L IBC for liquids
- Neutral print or private label
Loading
20–22 MT of powder per 20 ft FCL, palletised or floor loaded. Liquid orders are planned by drum or IBC to stay inside weight limits.
Lead time
7–15 days for production after deposit. Stock grades are dispatched within 5 days; samples leave in 48 hours.
Documents
COA, MSDS, TDS, packing list and certificate of origin with every lot. Third-party inspection can be arranged before shipment.
Payment
T/T with 30% deposit, balance against copy of B/L. L/C at sight accepted for established buyers.
Ports & terms
Shipment from Qingdao, Shanghai or Tianjin. FOB, CIF and CFR quotations on request.
