Wastewater Treatment Products | Inorganic Coagulants

Efficient and Reliable Coagulation for Industrial Wastewater Treatment

Industrial wastewater often contains suspended solids, organic matter, and other contaminants that must be effectively removed before discharge or reuse. Without proper treatment, these pollutants can lead to regulatory violations, environmental harm, and operational inefficiencies. Coagulation is a critical step in wastewater treatment, helping to destabilize and aggregate fine particles for easier removal.

ETI provides high-performance inorganic coagulants designed to enhance solid-liquid separation, improve treatment efficiency, and ensure compliance with environmental regulations. Our advanced formulations are tailored for municipal and industrial wastewater systems, offering cost-effective solutions that reduce chemical consumption while maximizing performance.

The Importance of Coagulation in Wastewater Treatment

Wastewater generated from industrial and municipal sources contains a mix of suspended solids, oils, fats, heavy metals, and organic contaminants. Without proper coagulation, these substances remain dispersed in water, making sedimentation and filtration difficult. Implementing an effective coagulant program helps:

  • Reduce turbidity and improve water clarity
  • Enhance sedimentation and filtration efficiency, lowering treatment costs
  • Minimize sludge volume, reducing disposal expenses
  • Improve biological treatment performance by removing excess organic load
  • Achieve regulatory compliance for discharge limits on suspended solids and contaminants
  • Ensure ongoing regulatory compliance for discharging facilities


By utilizing ETI’s inorganic coagulants, facilities can enhance wastewater treatment efficiency while reducing environmental impact.
