A water treatment system including an enclosure for water to be treated, a multiplicity of biomass carriers located within the enclosure, at least one airlift in the enclosure for raising the water and the biomass carriers and at least one mechanical biomass carrier accumulated residue removal apparatus operative to remove accumulated residue from the biomass carriers.

An apparatus provides a water bottle mouthpiece attachment which can filter microplastics and other contaminant substances from bottles, particularly disposable plastic water bottles. The filter of the apparatus includes a filter housing that is attached to a cap that fits inside a common plastic bottle. Soft rubber rings, tapering from to radially larger on the top to radially smaller on the bottom in a generally conical fashion, ensure a watertight fit to the inside opening of any drinking bottle. A friction closing/opening spout at the top of the filter enables selective opening of the bottle and prevents accidental spillage of bottle contents. The filter housing is also offset from the center, giving space to an air valve that allows air to enter the bottle without disturbing the flow of water from the bottle, thus providing optimal lamellar flow without allowing fluid to escape through the air valve during consumption.

A system of filtering runoff water from a roof cleaning is used to remove contaminants from water that has been used for rooftop cleaning. The system is also configured to gather water noninvasively from downspouts or topographically low points upon the roof. The system of filtering runoff water from a roof cleaning utilizes a pump that is connected to a large bin for filtration. The pump is placed at a low point upon the rooftop, thus enabling optimal water collection for subsequent pumping. The bin contains a disposable filter through which pumped water may pass, either through force from the pump pressure or due to the effects of gravity. Clean water is then ejected from the bin, or otherwise guided to an appropriate drainage area. This arrangement allows for easy maintenance, as a rooftop cleaner need only to swap out the old filter for a new one after cleaning.
