The CLT-300 available from Karcher is an above-ground, cone-bottom tank used to enhance existing pit water treatment systems that may be too small or do not provide adequate pre-treatment. With its 300-gallon capacity, this cone-bottom tank can provide lower clean-out maintenance costs compared to many in-ground pit systems, and it can be applied as pre-treatment, post-treatment, or as a stand alone treatment system. The CLT-300 utilizes cross-linked polyethylene cone-bottom tanks with steep, 55-degree slopes for maximum solids separation. Each tank has a full open top with removable lid and includes heavy duty metal stand with cradle. These base models are also incorporated into other Water Maze clarifier models and can be an economical alternative to expensive pit water treatment system reconstruction costs.
