Stormwater runoff and dewatering from construction sites can have a significant negative impact on the quality of neighboring water sources. As stormwater flows over a construction site, it picks up sediment, debris, oil, chemicals and other pollutants. Without mitigation, the water can run off the site into streams, lakes, storm drains and sewer systems. Sediment, suspended soil particles and pollutants in the runoff can reduce the amount of sunlight reaching aquatic plants, clog fish gills, smother aquatic habitat and spawning areas, and impede fish navigation. The polluted runoff can harm or kill fish and other wildlife and eventually makes its way into drinking-water sources.

HaloKlear® products treat stormwater runoff and dewatering from construction sites, ensuring clean, safe and healthy water sources while allowing contractors to meet local and state agency requirements and to remain productive throughout the year.

How Does It Work?
HaloKlear products naturally reverse the process of water contamination through a patented, chitin-based HaloSource® technology. Chitosan and chitosan derivatives—refined forms of chitin—reduce turbidity, phosphorous, metals and grease in stormwater. In turbid water, HaloKlear causes the coagulation of sediment particles, which then allows for the sediment to be removed through gravity settling, biofiltration, sand filtration or cartridge filtration.

What Is Chitosan?
Chitosan is a natural biopolymer of chitin, nature’s second most abundant polymer. Chitin is the structural material found in the shells of crustaceans such as shrimp, crabs and lobsters and is also found in insect shells and fungi cell walls.

Why Is Chitosan Important?
Chitosan has the ability to flocculate suspended sediments in turbid water, allowing the sediments to settle out. The flocked sediment is nontoxic and biodegradable and can be dewatered more easily than synthetic polymer flocculants can be. Chitosan-based water treatment agents have been used in water clarification for decades in various industrial and municipal applications including drinking-water purification, pond and lake clarification, and commercial aquarium clarification.

What Makes HaloKlear a “Green” Solution?
HaloSource, the manufacturer of HaloKlear brand products, recycled almost 900,000 pounds of crab, lobster and shrimp shells in 2007. Ordinarily, this waste would have been abandoned by processing companies and discarded into landfills. Not only does HaloKlear clean and protect the environment, keeping our streams and water sources safe for generations to come, but it does so by reducing the amount of waste sent to landfills.
