ChemTreat - Defoamers Plant
ChemTreat has a full product line for foam reduction and elimination in industrial water systems, and can provide a defoaming agent best-suited to optimize your system. We provide defoamer technologies to eliminate foam in boilers, cooling towers, and effluent systems, and ensure smooth operating conditions. The most common of these defoaming agents are surface tension reduction and bubble-wall destabilization products. Defoamer products consist of silicone, oil-based, ester-based, water-based, and polymeric constituents.
A Proven Process for Chemical Wastewater Treatment
Industrial wastewater treatment requires appropriate technologies as well as proper application. After performing a full system audit and all requisite testing, ChemTreat can customize a wastewater treatment process that optimizes chemical usage, effluent flow rates, and off-site treatment costs. We provide environmentally-efficient and sustainable treatment methods for effluent systems. We also have expertise in water reuse systems and zero-liquid discharge. ChemTreat will select the optimal organic and inorganic chemicals to reduce your discharge costs and optimize your effluent system.
Our wastewater specialists have experience with unique wastewater treatment processes for industries such as metals, oil and gas, automotive, food and beverage, mining, steel manufacturing, and pulp and paper processing. ChemTreat is committed to helping facilities integrate industrial wastewater treatment programs.
Oil Removal
Our industrial wastewater treatment programs offer a complete portfolio of surfactants, coagulants, and emulsion flocculants typically used in oil removal applications.
Emulsion Breakers
ChemTreat’s chemical treatment programs offer a complete portfolio of emulsion flocculants, which are suspensions of minute beads of high-molecular-weight polymer in water, emulsified in an oil carrier. The minute beads are approximately 1 micron in diameter and contain concentrated polymer dissolved in water. These concentrated polymer beads, or “hydrogels,” are dispersed in a carrier fluid of high-flashpoint mineral oil by means of a dispersing surfactant that keeps the hydrogels from coalescing into larger droplets. Because the hydrogels are of greater density than the carrier oil, they are prone to settle over time, resulting in concentrated polymer solids on the bottom of the container with a layer of oil on the top. This separation can develop faster if the droplets are large, so keeping the droplets small and well-dispersed is important in maintaining the product stability.
Emulsion flocculants are typically copolymers of acrylamide, a nonionic building block, and a charge-bearing monomer. In the case of anionic flocculants, the anionic charge is produced by co-polymerizing acrylic acid with the acrylamide monomer. The ratio of acrylic acid to acrylamide determines the degree of charge on the molecule.
In the case of cationic flocculants, the cationic charge is provided by co-polymerizing AETAC, a methyl acrylate-derived cationic monomer with the acrylamide monomer. The ratio of AETAC to acrylamide determines the degree of charge on the molecule.
Because the hydrogels are made up of tightly-coiled polymer chains, mixing energy and time are required to ensure full contact of the hydrogels with the water to enable the polymer chains to uncoil fully. The polymer chains may be cationic, anionic, or nonionic with varying charge weights. The charge on the chain helps uncoil the chain, so a higher-charged polymer will open faster than a low-charged or uncharged polymer.
