Product Concept

PolyDADMAC, also known as PDADMAC or PDMDAAC, is a widely used cationic coagulant in water treatment. DA402 is engineered for operational stability and ease of use, making it a practical choice for automated dosing systems, continuous water treatment processes, and facilities with limited manual control.

DA402 is not designed only for treatment performance. It is also developed to help treatment systems run more smoothly, with easier dosage control and more consistent clarification behavior under daily operating conditions.

Why DA402 Is Easy to Use

Many treatment plants face common challenges such as overdosing or underdosing, fluctuating treatment results, and strong dependence on operator experience. DA402 is developed to reduce these operational problems.

Predictable Dosing Behavior

DA402 responds smoothly to dosage changes, making it easier to fine tune and control compared with more sensitive coagulant systems.

Stable Floc Formation

It supports more consistent floc size and reduces the risk of floc breakage, helping improve settling stability in continuous operation.

Low Sensitivity to Mixing Conditions

DA402 performs well even when mixing is not ideal, making it suitable for older treatment systems and facilities with limited equipment performance.

Performance in Automated Systems

Continuous Dosing Systems

DA402 helps maintain stable chemical feed and minimizes fluctuation in treatment performance during long operation cycles.

PLC Controlled Plants

Its predictable response curve makes it easier to integrate with sensors and automated control logic in PLC based water treatment systems.

Remote Operation Facilities

DA402 reduces the need for frequent manual adjustment and helps maintain more consistent output quality in remotely operated plants.

Key Benefits

Technical Specifications

Ideal Application Conditions

System Needs Stability

DA402 is recommended for municipal plants and industrial continuous systems where stable operation is a higher priority than aggressive treatment response.

Operators Want Simplicity

It is suitable for systems that need easier dosage adjustment and lower risk of operational error during daily treatment control.

Equipment Is Not Perfect

DA402 performs well in older dosing systems and installations with limited mixing efficiency, helping maintain acceptable treatment results under non ideal conditions.
