KemSep C-9014 and KemSep C-9015 are PolyDADMAC (polydiallyldimethylammonium chloride)-based cationic organic coagulants developed for water treatment and solid–liquid separation applications. These products are characterized by high cationic charge density and are primarily used as charge-neutralizing agents to remove suspended solids, colloidal particles, natural organic matter, emulsified oils, and color-causing compounds. They are commonly applied in municipal drinking water treatment, municipal and industrial wastewater treatment, sludge conditioning, papermaking, mining, oil and gas, textile processing, food manufacturing, and other industrial clarification systems. PolyDADMAC products such as KemSep C-9014 and KemSep C-9015 are widely recognized for water treatment and sludge dewatering applications because of their strong coagulation performance and compatibility with other treatment chemicals.

Municipal drinking water treatment

One of the most important applications of KemSep C-9014 and KemSep C-9015 is the purification of raw water used for municipal drinking water supplies.

Surface water from rivers, reservoirs, and lakes commonly contains:

• Fine suspended solids
• Natural organic matter
• Humic substances

These contaminants remain dispersed because they possess negative surface charges.

KemSep C-9014 and KemSep C-9015 rapidly neutralize these charges, allowing particles to form microflocs that are subsequently enlarged during flocculation and removed through sedimentation and filtration.

Major benefits include:

• Reduced turbidity.
• Improved color removal.
• Enhanced algae removal.
• Better removal of natural organic matter.
• Longer filter operating cycles.
• Improved drinking water quality.
• Lower overall chemical consumption.
