BLU ACH POWDER & LIQUID

Aluminum Chlorohydrate (ACH) Powder & Liquid for Water Treatment

High-Basicity Coagulant for Drinking Water, Industrial Wastewater and Sludge Treatment in Russia & CIS

Bluwat Aluminum Chlorohydrate (ACH) is a highly concentrated, pre-hydrolyzed aluminum-based coagulant designed for municipal and industrial water treatment. With high alumina content and 80–85% basicity, ACH provides efficient destabilization of suspended solids, colloids, color-causing substances and selected organic contaminants.

Available in both powder and liquid forms, BLU ACH is suitable for water treatment plants and industrial facilities across Russia, Kazakhstan, Uzbekistan, Belarus, Armenia, Azerbaijan and other CIS markets.

Product Overview

Aluminum Chlorohydrate is one of the most concentrated products in the polyaluminum coagulant family. Its high Al₂O₃ content and high degree of neutralization help provide effective coagulation while causing less change to the treated water’s pH than many conventional aluminum salts.

BLU ACH is available in two main water-treatment grades:

ACH Powder: white powder with Al₂O₃ content above 46%
ACH Liquid: clear, colorless liquid with Al₂O₃ content above 23%

Both forms have a typical basicity of 80–85%. Powder ACH is often selected for long-distance transportation and flexible inventory management, while liquid ACH is suitable for facilities requiring convenient preparation and continuous dosing.

Why Choose Aluminum Chlorohydrate?

High Active Aluminum Content

ACH contains a high concentration of Al₂O₃, allowing treatment plants to introduce more active coagulant material with a smaller product volume compared with lower-concentration aluminum coagulants.

High Basicity

With a basicity of 80–85%, ACH is highly pre-neutralized. This helps reduce the amount of alkalinity consumed during coagulation and generally produces less disturbance to the treated water’s pH.

Broader Operating pH Flexibility

ACH can provide effective coagulation over a broader pH range than many traditional metal-salt coagulants. This can be valuable where raw-water conditions change seasonally or industrial wastewater composition varies between production batches.

Efficient Turbidity and Color Removal

The highly charged aluminum species destabilize fine suspended particles and colloids, supporting faster floc formation and improved clarification.

Potential for Lower Treatment Dosage

Due to its high Al₂O₃ content and basicity, ACH may achieve the required treatment result at a lower product dosage than conventional aluminum salts. Actual dosage depends on the water characteristics and must be established through jar testing.

Suitable for Multiple Treatment Objectives

ACH can be evaluated for turbidity, color, phosphorus, selected heavy metals, organic matter and sludge-conditioning applications.

Main Applications in Russia and CIS Markets

1. Drinking Water Clarification

ACH can be used as a primary coagulant in drinking-water treatment to remove:

Suspended solids
Fine colloidal particles
Turbidity
Natural color
Selected organic matter

Its relatively small effect on treated-water pH can be useful when source-water alkalinity is limited or when seasonal water quality changes require more stable coagulation control.

For drinking-water applications, the final grade, dosage and regulatory suitability must be confirmed according to local requirements.

2. Municipal Wastewater Treatment

In municipal wastewater systems, ACH may be used for:

Primary clarification
Turbidity reduction
Phosphorus removal
Sludge thickening
Sludge-conditioning and dewatering support
Treatment of variable influent loads

ACH may be used alone or evaluated together with a suitable polyacrylamide flocculant to improve floc size and solid-liquid separation.

3. Industrial Wastewater Clarification

BLU ACH is suitable for evaluation in industrial wastewater containing suspended solids, emulsified impurities, color or organic contaminants.

Relevant industries across Russia and the CIS include:

Mining and mineral processing
Metallurgy and metal finishing
Chemical manufacturing
Pulp and paper
Oilfield and refinery-related water treatment
Textile and dyeing operations
General manufacturing wastewater

Because industrial wastewater composition varies significantly, laboratory testing is required before full-scale use.

4. Heavy-Metal Removal

ACH can support the coagulation and separation of precipitated or particle-associated metals. It is normally incorporated into a complete process that may include:

Chemical precipitation or a specialized heavy-metal precipitant
pH adjustment
ACH coagulation
PAM flocculation
Sedimentation or dissolved air flotation

ACH alone should not be assumed to remove all dissolved or complexed metals. The complete treatment process should be designed according to the metal species and wastewater chemistry.

5. Phosphorus Removal

ACH provides aluminum species that react with phosphate and support its removal through precipitation and coagulation. It can be applied in municipal and industrial systems requiring lower effluent phosphorus.

The optimum dosing point should be selected according to the treatment process, phosphorus level and biological system requirements.

6. TOC and Organic-Matter Reduction

ACH can help remove coagulation-sensitive fractions of total organic carbon and natural organic matter. Performance depends on the nature of the organic compounds, pH, alkalinity and competing contaminants.

7. Sludge Thickening and Dewatering

ACH can be used for sludge conditioning before thickening or mechanical dewatering. It helps destabilize fine particles and may improve the response to a downstream polymer.

Bench-scale testing should evaluate:

Floc structure
Filtration or drainage rate
Sludge-cake solids
Centrate or filtrate clarity
Total chemical consumption

8. Struvite Control

ACH may be evaluated as part of phosphorus-management programs intended to reduce conditions associated with struvite formation in wastewater and sludge-treatment systems.

How ACH Works

When added to water, ACH supplies highly polymerized, positively charged aluminum species. These species neutralize the negative surface charge of suspended particles and colloids.

The treatment process generally involves:

Rapid DispersionACH is mixed quickly into the water.

Charge NeutralizationPositively charged aluminum species destabilize negatively charged contaminants.

Microfloc FormationDestabilized particles begin to aggregate.

Floc GrowthGentle mixing or the addition of PAM builds larger, separable flocs.

Solid-Liquid SeparationFlocs are removed by sedimentation, flotation or filtration.

The final result depends on water chemistry, dosage, mixing energy and downstream separation equipment.

ACH Powder or ACH Liquid: Which Form Should You Choose?

Selection Factor	ACH Powder	ACH Liquid
Active Al₂O₃ content	Higher, >46%	>23%
Transportation	More concentrated for long-distance shipping	Higher shipping weight per unit of active content
On-site preparation	Requires controlled dissolution	Can be introduced through a liquid dosing system
Storage	Suitable for dry chemical storage	Requires compatible liquid storage tanks
Handling	Dust control and dissolution equipment needed	Pumping and transfer equipment needed
Typical preference	Importers, distributors and remote industrial sites	Plants with continuous liquid dosing systems

For northern regions and sites exposed to severe winter conditions, storage infrastructure should be considered carefully. Powder ACH may offer logistical advantages where suitable temperature-controlled liquid storage is difficult to maintain. Liquid ACH should be protected and stored according to the applicable product and local handling requirements.

ACH Compared with Conventional PAC and Aluminum Salts

Characteristic	ACH	Conventional PAC or Aluminum Salts
Al₂O₃ concentration	High	Usually lower, depending on grade
Basicity	80–85%	Generally lower, depending on product
Effect on water pH	Typically smaller	May consume more alkalinity
Product dosage	Potentially lower	May require a higher product dosage
pH operating flexibility	Broad	Product-dependent
Application	High-performance municipal and industrial treatment	General coagulation applications

The best coagulant cannot be selected from product chemistry alone. Raw-water quality, treatment targets, sludge production, alkalinity and total treatment cost should all be compared through controlled testing.

Frequently Asked Questions

Is ACH the Same as PAC?

ACH belongs to the broader family of pre-hydrolyzed aluminum coagulants, but it normally has higher alumina content and higher basicity than conventional PAC grades. It is often selected when concentrated active content and limited pH disturbance are important.

Can ACH Replace the PAC Currently Used in Our Plant?

Possibly, but replacement should be based on jar-test results. The dosage should not be converted directly by product weight because ACH and PAC may have different Al₂O₃ concentrations and basicity.

Does ACH Significantly Reduce Water pH?

ACH typically has a smaller effect on treated-water pH than less-neutralized aluminum salts. However, the actual pH change depends on dosage, raw-water alkalinity and other treatment chemicals.

Can ACH Be Used with Polyacrylamide?

Yes. ACH can destabilize suspended particles, after which a suitable anionic, cationic or nonionic PAM may be used to build larger flocs. Polymer type and dosage must be selected through testing.

Is ACH Suitable for Phosphorus Removal?

Yes. ACH can react with phosphate and support its removal by precipitation and coagulation. The required dosage depends on the phosphorus concentration and treatment target.

Can ACH Remove Heavy Metals?

ACH can help separate precipitated or particle-bound metals. Dissolved or complexed heavy metals may require pH adjustment or a specialized heavy-metal precipitant before ACH coagulation.

Which Form Is Better for Import into CIS Countries?

Powder ACH is more concentrated and may reduce transported volume per unit of active material. Liquid ACH offers simpler dosing for plants with suitable pumps and storage tanks. The best choice depends on logistics, storage conditions and daily consumption.

How Is the Correct ACH Dosage Determined?

There is no universal dosage. Selection should be based on jar testing using the actual source water or wastewater, followed by an on-site trial.
