NINGBO INNO PHARMCHEM CO.,LTD. is proud to introduce CW-15, a high-efficiency liquid heavy metal remover designed specifically for industrial wastewater treatment. This innovative chemical product offers a safe and environmentally conscious approach to eliminating problematic heavy metal ions from aqueous streams. Unlike traditional methods that may struggle with certain metal forms or environmental impact, CW-15 provides a robust and reliable solution.

Heavy metal contamination in industrial wastewater is a significant environmental challenge, posing risks to ecosystems and human health. Effective removal is crucial for compliance with stringent environmental regulations and for protecting water resources. CW-15 acts as a potent heavy metal catcher, chemically binding with various metal ions to form stable precipitates that can be easily separated from the water.

The mechanism of action involves the formation of highly stable organosulphide compounds with a wide range of monovalent and divalent metal ions commonly found in industrial effluents. These include ions such as Fe²⁺, Ni²⁺, Pb²⁺, Cu²⁺, Ag⁺, Zn²⁺, Cd²⁺, Hg²⁺, Ti⁺, and Cr³⁺. By converting soluble or complexed metal ions into insoluble precipitates, CW-15 effectively removes them from the water phase, achieving a high level of purification.

One of the key advantages of CW-15 is its high safety profile. It is characterized as non-toxic, lacking unpleasant odors, and it does not produce toxic byproducts during or after the treatment process. This makes it a preferred choice for applications where environmental and operator safety are paramount concerns. Furthermore, the precipitates formed by CW-15 are remarkably stable, even under challenging conditions such as elevated temperatures (up to 200-250ºC) or in the presence of dilute acids. This stability ensures that there is no risk of secondary pollution through the re-dissolution of trapped heavy metals into the environment, for instance, from sludge disposal sites exposed to rainwater.

The versatility of CW-15 is another significant benefit. It demonstrates good removal efficacy across a wide pH range, making it suitable for treating both acidic and alkaline wastewaters without requiring extensive pH adjustment beforehand, although a slight pH adjustment to the range of 7-10 is typically recommended for optimal performance. This flexibility simplifies the treatment process and reduces chemical costs associated with pH control. Importantly, CW-15 is effective even when heavy metal ions are present in the form of complex salts, such as those involving EDTA or tetramine ligands, which are notoriously difficult to remove using conventional hydroxide precipitation methods. When multiple metal ions coexist in the wastewater, CW-15 can efficiently remove them simultaneously, streamlining the treatment process.

Beyond its chemical precipitation capabilities, CW-15 also exhibits good flocculation properties. The precipitates formed tend to aggregate into larger particles, which facilitates solid-liquid separation. This leads to enhanced sedimentation and filtration rates, resulting in cleaner treated water and easier sludge dewatering. The simple application method, typically involving dosing the chemical into the stirred wastewater followed by flocculation and sedimentation/filtration, makes it easy to integrate into existing wastewater treatment plants.

CW-15 finds extensive application in various industrial sectors that generate heavy metal-laden wastewater. These include, but are not limited to, desulfurization wastewater from coal-fired power plants (especially wet desulfurization processes), wastewater from printed circuit board plating facilities, electroplating factories (for metals like zinc), photographic rinse streams, petrochemical plants, and automobile production facilities. Its broad applicability makes it a valuable tool for industries facing diverse heavy metal contamination challenges.

Typical reference dosages for CW-15 are provided based on the concentration and type of heavy metal ions present, demonstrating its effectiveness even at relatively low concentrations. For instance, treating water containing 10PPM of certain heavy metal ions may require dosages ranging from approximately 0.055 L/M³ for Lead to 0.20 L/M³ for Nickel or Zinc, highlighting its efficiency and the need for application-specific dosage optimization.

The product is supplied as a liquid, typically colorless or yellow in appearance, with specifications indicating a solid content of more than 15%, a pH (1% water solution) between 10-12, and a density greater than 1.15 g/cm³ at 20ºC. These specifications ensure consistent product quality and performance.

CW-15 is conveniently packaged in various sizes, including 25kg drums, 200kg drums, and 1000kg IBC drums, to suit different operational scales. It has a shelf life of 12 months when stored properly.
