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.
