Stronger separation, better process support 

In water and wastewater treatment, effective separation starts with how well fine suspended matter can be gathered and removed. When particles remain dispersed, they can affect clarification, sludge handling, downstream efficiency, and overall treatment control across industrial and municipal systems. 

Calflock Flocculants are designed to support these challenges with solutions that help fine particles bind into larger, removable flocs. As part of Caldic’s broader water treatment offer, Calflock supports treatment performance with a practical view of process conditions, operating priorities, and application fit. The current water treatment scope includes flocculants within a broader portfolio for water treatment, wastewater treatment, process water treatment, and related treatment support.

How Calflock supports treatment

Flocculants support separation by helping fine particles gather into larger and more stable flocs. This creates a stronger foundation for treatment steps such as clarification, sedimentation, filtration, and sludge handling. By improving how suspended matter comes together and can be removed, flocculants help support more controlled treatment performance across water and wastewater systems where separation efficiency is an important part of the overall process.

More than chemistry alone

Choosing the right flocculant depends on more than chemistry alone. In practice, treatment goals, solids load, sludge characteristics, handling requirements, equipment setup, and operational priorities all influence what the right fit looks like. 

Across the flocculants category, the main decision factors often come down to ease of use, application fit, safety, sustainability, and cost in use. These same priorities also connect naturally to Caldic’s broader water treatment focus, which includes process optimization, sludge management, water recovery and reuse, energy efficiency, and regulatory support.  

That is why Calflock is best understood not only as treatment chemistry, but as part of a broader operational conversation around performance, process support, and long-term treatment priorities.

Why choose Caldic

Caldic supports customers with flocculant solutions that connect treatment chemistry with practical operational needs. Our role goes beyond supply alone. We help customers approach treatment performance with a broader view of clarification, sludge handling, process support, and wider operational priorities. 

By combining category knowledge with a broader water treatment perspective, Caldic helps customers navigate treatment needs with greater clarity across industrial and municipal systems. This creates a more connected approach to performance, process support, and longer-term treatment priorities. 


Part of a broader water treatment offer

Calflock is one part of Caldic’s wider water treatment platform. The broader portfolio also includes coagulants, bioaugmentation products, biocides, oxidants, antifoams, ion-exchange resins, membranes, filtration aids, adsorbents and activated carbon, regeneration chemicals, inhibitors, and performance additives. This broader scope helps customers address treatment needs with a more connected view of process performance, operational efficiency, and treatment priorities.  

Caldic’s water treatment scope also covers physico-chemical treatment, biological treatment, sludge management, pretreatment, effluent polishing, process optimization, regulatory and permit support, water recovery and reuse, waste management, energy efficiency, and contaminant management.
