Product Short Description

Product Overview

In reservoir water clarification, the practical objective is to manage changes caused by rainfall, turnover, algae growth and catchment runoff without sending unstable floc to filters. PAC-01 is used as a coagulant, not as a complete treatment system.

Its role is to aggregate suspended and colloidal material into floc that can be settled or floated before filtration. The grade is positioned for drinking-water and color-sensitive process-water applications, and its spray-dried form dissolves rapidly when the solution is prepared correctly.

Application Scenarios and Control Points

Relevant use cases include reservoir drinking-water plants, lake-water packages and seasonal intake systems.

Operators should follow turbidity, apparent color, algae carryover, floc buoyancy and filtered-water performance. These indicators show whether the treatment target is being achieved and whether the dose is creating unnecessary sludge or downstream carryover.

How Polyaluminium Chloride Works

PAC is a pre-hydrolyzed inorganic polymeric coagulant. After dispersion, its cationic aluminium species adsorb on negatively charged particles and reduce the electrical barrier that keeps them apart.

As hydrolysis continues, aluminium hydroxide floc provides a sweep-coagulation surface that captures fine particles. Separation performance therefore depends on product dose, pH, alkalinity, mixing sequence, flocculation time and the selected settling, DAF or filtration equipment.

Recommended Application Approach

How to Choose the Right PAC Grade

Choose PAC-01 because 0.1% maximum insolubles and white powder are useful for a clean clarification program. Start with the product specification, but make the final selection on representative water.

Compare at least three doses, include the current coagulant as a control and keep pH, mixing energy and settling time consistent. The TDS gives about 1–15 g/MT for solid PAC as a general reference; the optimum may differ with the water and must be confirmed by laboratory and plant trials.

Why Work With Bluwat Chemicals

Bluwat Chemicals has manufactured water-treatment chemicals since 2000. The company operates three production bases, exports to more than 80 countries and has served over 5,000 industrial customers. For reservoir water clarification, this experience supports grade matching, sample evaluation and communication between the buyer, sales team and technical team before scale-up.

Direct factory support includes batch COA, current TDS and SDS documents, packing checks and traceable quality control for the selected PAC grade. Buyers can compare PAC-01 with other PAC grades using actual water rather than relying only on product color or one headline parameter.

Packaging, Solution Preparation and Storage

Solid PAC is packed in a 25kg inner plastic bag with a polypropylene woven outer bag. Store the sealed original package in a cool, dry place away from heat, flame and direct sunlight.

Prepare a 2–20% solution before dosing, using clean water and sufficient mixing. Do not use wet, contaminated or severely caked material without evaluation.
