  • Patent number: 8470170
    Abstract: The invention is an apparatus and method for treating fluid in a pool, spa, or water tank, etc., using ozone and treated air. A fluid filter is placed in an auxiliary reservoir or a smaller fluid tank located in or next to the pool, spa, or main water tank. An ozone generator pumps a combination of ozone and air into the smaller fluid tank. Fluid in the smaller fluid tank passes through a filter and back into the main reservoir without the use of any fluid pump. More specifically, a vertical lift tube is placed beneath the smaller fluid tank so that the open top of the lift tube is within the smaller fluid tank. Fluid from the main reservoir is piped to the bottom of the lift tube. Ozone and air from the ozone generator is also piped into the lift tube near its bottom. The fluid flows through the filter due to the effect of ozone and air bubbles released by a diffuser at the bottom of the lift tube.

  • Publication number: 20130048547
    Abstract: Provided is a filtration system for filtering contaminants and impurities from a coolant, such as water, applied to an air conditioner unit for cooling the air conditioning unit to increase the efficiency thereof. The filtration system filters the coolant to achieve a desired purity level to allow the coolant to mitigate corrosion or particle buildup on the air conditioning unit when the coolant is applied thereto. Along these lines, if the purity level is too low, the contaminants present in the coolant may corrode the air conditioning unit. Conversely, if the purity level is too high, the coolant itself may react with the air conditioning unit, which may lead to corrosion or other structural issues. Thus, the filtration system is specifically configured and adapted to purify the coolant to achieve a purity level within a desirable purity range.

One embodiment relates to a water treatment system for aircraft that may make it possible to treat a gray water/black water mixture accumulated on board of an aircraft during its operation in sufficient quantity and quality for use in a downstream reformer. This means that the water circuit within the aircraft is closed and costly water tanks are eliminated.

  • Publication number: 20080272050
    Abstract: Disclosed herein are systems and methods for decontaminating a contaminated fluid that integrate ultraviolet radiation in an advanced decontamination process, and a honing material, along with a cross-flow membrane filter, into a single closed-loop system. This approach combines the advantages of chemical-free advanced decontamination technology, long-life wiper-free UV disinfections, and maintenance-free ceramic MF/UF membranes to provide multi-barrier protection. Such technique provides a 100% fluid recovery system (zero reject stream). In one embodiment, the system comprises a filtration membrane and a honing material located in the contaminated fluid that is sufficient to scrub foulants from the membrane, as well as any other components that honing material comes in contact with, while forming a dynamic filtration coating on the membrane as the contaminated fluid pass through the membrane.
