A portable pool filter cleaning assembly is configured to retain a pool filter on support rod and allow the pool filter to spin from a spray of water. The spinning filter releases debris from the filter surface through centrifugal force. The assembly has drainage features to ensure proper drainage of water collected within the interior of the pool filter and enable proper spinning from the spray of water. The assembly utilizes a support rod with a bottom filter retainer that is conical in shape for engaging with the pool filter aperture. The bottom filter retainer may further have a bearing that enables the pool filter to rotate freely about the rod with very little force. The assembly may include a stand for securing the support rod on a hard surface, such as concrete or on an uneven lawn surface.

An internal combustion engine exhaust modification system for transforming exhaust emissions from an internal combustion engine into modified exhaust emissions. The exhaust modification system includes a housing extending between inlet and outlet ends thereof. The system also includes an impeller rotatably mounted in the housing, and a filter subassembly downstream from the impeller. The filter subassembly removes part of particulate matter and liquid droplets in the exhaust emissions to transform the exhaust emissions into modified exhaust emissions. The system includes a conduit extending between an inner end thereof positioned to direct cooler air exiting therefrom into the housing toward the filter subassembly, and an outer end thereof. The system also includes a funnel subassembly having a funnel body for directing the cooler air into the outer end of the conduit.

The present invention relates to a chemical composition that removes accumulated impurities from a DPF in an easy and fast manner. The filter does not need to be removed from the vehicle, as cleaning is done by injecting the liquid through the temperature probe opening, and the chemical composition used is completely biodegradable. Cleaning with the chemical composition of the invention is not time consuming, is easy to perform and, results in completely purified DPF. Presented chemical composition for cleaning DPFs comprises alkyl sulfonic acid and distilled water, wherein the alkyl sulfonic acid is a short alkyl chain sulfonic acid with up to 4 carbon atoms (methane sulfonic acid, ethane sulfonic acid, propane sulfonic acid or butane sulfonic acid), with methane sulfonic acid being preferred due to its properties and availability.

Disclosed are methods for concentrating solids and removing solids from a filter medium. The method includes the step of concentrating first particles of a first solid by removing a fluid stream through a filter medium in a filter. At least some of the first particles become blocking particles that block pores of the filter medium. The method also includes the step of inserting second particles of a second solid into the filter. These second particles scrape, vibrate, agglomerate, or a combination thereof along the filter medium, thus dislodging at least a portion of the blocking particles.
