The present disclosure is generally directed to devices and methods of treating aqueous solutions to help remove or otherwise reduce levels, concentrations or amounts of one or more contaminants. The floor treatment device may include a handle portion that is attached to a base, which includes a floor treatment portion. An optical inspection system utilizes an illumination source and an imaging device to obtain images of the transparent sheets. The fold region is substantially free from the susceptor material allowing a food product heated on the food product surface to remain flexible to permit folding of the food product with reduced cracking or breaking. Polymer compositions containing the dual phase fillers are further described. The modules are removably attachable to the receivers by at least two non-latching, dry-break connectors.
