  • Patent number: 10087081
    Abstract: The invention provides a method for improving the effectiveness of colloidal silica. The method involves removing enough charged impurities from the colloid to prevent the charged particles from causing the colloid to become a viscous gel. The method however also involves not removing too many charged particles so the silica material doesn't gel by cross-linking with itself. This method is quite effective because it recognizes that materials that have accumulated during the formation of the colloid do perform an important function, but they can perform better at a lower concentration.

  • Patent number: 9850156
    Abstract: A side-stream particle precipitator system for the breakdown and removal of organic and inorganic suspended solids in water cooling systems using a plurality of ionizer treatment units utilizing electric and electro-magnetic fields and a mechanical vortex precipitating system with a static mixer for increasing retention time of the water complex in the precipitator to remove particulate materials contained in the water complex as suspended solids. The system also uses high voltage electrodes for charging the water complex to breakdown laminar flow at the conduit walls to mechanically dislodge any build-up of bio-materials or chemical compounds along the walls resulting in an increase in thermal conductivity.

  • Patent number: 9724630
    Abstract: A removable, reusable, pleated woven wire filter comprising: (a) a stainless steel perforated core having one-half-inch stainless steel round bar reinforcement rings welded to one-half-inch stainless steel round bar cross bars to create bar-ring junctures, and having 11-gauge stainless steel attachment clips welded to each end of the perforated core; (b) a three-layer stainless steel pleated woven wire filter media wrapped around the perforated core, the filter media having spaced apart pleats with external peaks, and an external filter media surface comprising the external peaks of the pleats; (c) a stainless steel flattened expanded metal shroud adjacent to and encircling the external peaks, and (d) a stainless steel top end cap base and a stainless steel bottom end cap base connected to the metal shroud, both cap bases sealed against top and bottom ends of the filter media with a stainless steel adhesive sealant rated at 2,000 degrees Fahrenheit.

  • Patent number: 9371659
    Abstract: A moving and floating pool cleaner apparatus includes a circular cap, a basket, a floating container, an attachment tube, and a T-shaped adapter. The moving and floating pool cleaner apparatus attaches with an existing automatic pool cleaner, and cleans the surface of the pool water by removing all of the floating debris. The circular cap is attached to the floating container, and the floating container is attached with the automatic pool cleaner through the attachment tube and the T-shaped adapter. The basket is positioned within the floating container. The pool water with floating debris goes into the floating container and then to the basket, where the basket retains bigger particles while the pool water redirects into the attachment tube. Then the pool water is forwarded into a pool cleaning unit so that the pool water can be thoroughly cleaned before pumps back into the pool.
