The invention includes a tablet made from a coagulant that will improve the settling of suspended solids in an aqueous media such as wastewater, recycled water, potable water, storm water, swimming pool water, spa water, boiler water, cooling tower water and industrial process water. The agent is a tablet containing at least one salt from the aluminum sulfate family in a mixture of organic and inorganic binders. The mixed material is especially adapted to lend itself to high speed molding operations. Such agent, when in molded form, provides controlled dissolution in an aqueous media, exhibits strength and non-chipping characteristics which is a benefit in shipping and handling and is free from dusting, flaking or other deteriorative factors. In its tablet form, this agent can be used in combination with a holding apparatus having slotted opening zones. |
