China Drinking Grade Polyaluminium Chloride Manufacturers, Suppliers and Factory

Product Overview

Ecolink Drinking Grade Polyaluminium Chloride (PAC) is an inorganic polymer coagulant synthesized via a controlled spray-drying process, specifically engineered for municipal potable water purification and industrial process water intake. Utilizing high-purity calcium aluminate powder and high-grade hydrochloric acid feedstocks, this grade delivers a higher effective polymeric aluminum content and a tightly controlled heavy metal profile compared to standard industrial alternatives.

The mechanism relies on rapid charge neutralization of colloidal impurities, instantly forming dense, high-molecular-weight aluminium hydroxide flocs that sweep out suspended solids, natural organic matter (NOM), and fine turbidity. It functions effectively across a broad temperature and pH spectrum, lowering residual dissolved aluminum levels while optimizing flocculation kinetics in rapid-mix settling basins.

Key Features

High Active Alumina Content (>= 30%):

Delivers higher net coagulation efficiency per unit weight, directly lowering annual chemical consumption and reducing sludge dewatering volume.

Spray-Dried Micro-Particle Morphology:

Hollow spherical micro-structures dissolve completely in cold water within 3 minutes without mechanical aggregation, preventing feeder-line clogging.

Strict Heavy Metal Control:

Multi-stage purification during synthesis maintains toxic element profiles well below WHO drinking water guidelines and NSF/ANSI Standard 60 benchmarks.

Wide Operating Envelope:

Maintains rapid floc formation across raw water temperatures ranging from 2 deg. C to 35 deg. C and a pH range of 6.0 to 8.5.

Low Residual Aluminum:

Minimizes dissolved aluminum carryover into finished municipal drinking water networks, preventing downstream scaling in distribution pipelines.

Applications

Municipal Potable Water Treatment:

Primary coagulant for surface water (rivers, lakes, and high-turbidity reservoirs) and groundwater purification in municipal water treatment plants.

Desalination Pre-treatment:

Removes suspended solids, colloids, and organic foulants prior to reverse osmosis (RO) membrane systems, controlling the Silt Density Index (SDI).

Beverage & Food Processing Intake:

Clarification of raw water intake for food and beverage manufacturing plants requiring strict chemical purity.

Swimming Pool Water Filtration:

Rapid turbidity reduction, color removal, and suspended solid aggregation in municipal aquatic complexes.

Product Selection Guide

Matching polymer chemistry to raw water parameters ensures optimal cost-per-cubic-meter performance:

Raw Water Source & Temp ---> Jar Test Evaluation ---> Select Basicity & Al2O3 ---> Plant Trial

Surface Water (T < 10 deg. C, High Turbidity): Choose 30% Spray-Dried PAC (Basicity 65% - 85%). Rapid dissolution prevents feed-line scaling during cold-weather operations.

Low-Turbidity, High-Organic Water: Choose PAC combined with Polyacrylamide (PAM) co-dosing. Jar testing is recommended to determine optimal charge neutralization ratios.

Corrosive / Low-Alkalinity Water: Choose Higher Basicity PAC (80% - 90%) to minimize raw water pH drop during hydrolysis, protecting pipeline integrity.

Manufacturing & Quality Control

Ecolink operates an ISO 9001-certified chemical synthesis facility utilizing automated reaction systems and specialized spray-drying towers.

Frequently Asked Questions

Q: What is the shelf life of Drinking Grade PAC powder, and how should it be stored to prevent caking?

A: The shelf life is 24 months when stored in unopened, original packaging in a cool, dry, and well-ventilated warehouse. Pallets must be kept off concrete floors and protected from high humidity and direct moisture exposure to preserve free-flowing powder characteristics.

Q: How does spray-dried PAC differ from roller-dried or liquid PAC in municipal water plants?

A: Spray-dried PAC forms hollow spherical particles that dissolve rapidly and completely in cold water without leaving insoluble grit. While liquid PAC eliminates on-site dissolution, high water weight increases long-distance shipping costs. Spray-dried powder delivers the lowest active-ingredient transport cost per dry metric ton.

Q: What is the recommended stock solution concentration for dosing systems?

A: A stock solution concentration of 5% to 10% (weight/volume) is standard. Dissolve the solid powder into clean dilution water under continuous mechanical agitation for 10-15 minutes until fully solubilized before feeding into the flash mixing basin.

Q: Does your Drinking Grade PAC comply with NSF/ANSI Standard 60 or equivalent regulatory frameworks?

A: Yes. Our production quality parameters conform to AWWA B403 and GB 15892-2020 standards for drinking water treatment chemicals. Third-party testing certificates verifying compliance with heavy metal limits are available for tender submissions.

Q: What is the typical Minimum Order Quantity (MOQ) and production lead time for full container loads?

A: The standard MOQ for ocean freight export is 1 20-foot container (20 metric tons). Dispatch lead time ranges from 7 to 12 calendar days following confirmation of payment terms or Letter of Credit (L/C).

Q: Can you customize basicity or particle size distribution for specific municipal treatment plant specifications?

A: Yes. Our reaction parameters and spray-drying atomization nozzles can be modified to manufacture custom basicity profiles (ranging from 45% to 85%) and specific bulk densities to meet specialized plant engineering requirements.
