Flocculants are an environmentally safe and economical treatment option. Storm Water Systems offers them in both solid and liquid forms and should be installed up stream of a clarifier or mechanical filter. Flocculants are substances which cause small particles to stick together thereby forming larger particles which both settle and filter more easily.
Additionally, flocculants can encapsulate oils and greases, also allowing these materials to be settled and filtered. Solid flocculants typically come in a sock to be placed on the ground where the storm water will be forced to flow through it. Liquid flocculants should be injected into a clarifier or mixing tank and allow ample time for the coagulation to take place.
