Coagulants

Coagulants are often a critical chemical component in a water or wastewater treatment process applications. Zeroday’s complete line of Z Clear™ highly cationic (positive) charged organic and inorganic coagulant products provide various benefits depending on the treatment process application and solids-liquids conditions:

  • In treating basins and ponds,coagulates aggregate very fine particles that enhance settling.
  • Enhances flocculation performance.
  • Increases supernatant clarities by coagulating the fines into larger aggregates that allows flocculating fine particles flocculants cannot effectively settle.
  • Neutralizes particle surface cationic charge demand, reducing flocculant dose requirements.

Zeroday supplies a broad variety of coagulant chemistries and variants within each chemical family to allow effectively treating a wide range of substrates and particle types, all having different response characteristics, water chemistry conditions and process system.

  • PolyDADMAC (polydiallydimethylammonium chloride).
  • Polyamines (epi-dma condensates: epichlorohydrin dimethylamine).
  • PAC (polyaluminum chloride).
  • ACH (aluminum chlorohydrate).
  • Ferric chloride.
  • Alum (aluminum chloride).
  • Calcium chloride.
  • Blends of these products to provide optimum coagulation and flocculation performance.

Lab and plant testing can determine whether a coagulant is required and performance benefit to optimize a process and system.  Incorporating a coagulant in a treatment program can affect flocculant selection and typically requires a complete evaluation of the coagulant-flocculant treatment suite. Zeroday technologists provide complete coagulant-flocculant program evaluation and identification, treatment program qualification and implementation.
