Abstract: Apparatus and systems for laundry wastewater treatment are provided. Generally, systems include one or more grinder pumps for receiving raw wastewater from laundry operations, a lint remover in fluid communication with the grinder pumps, a sediment filter in fluid communication with the lint remover, an ozone treatment chamber in fluid communication with the sediment filter, and a carbon filter. Methods can provide for continuous treatment of laundry wastewater that can be reused in laundry operations, or passed to a wastewater stream (such as sewage).

Abstract: Apparatus and systems for point of entry water purification using reverse osmosis are provided. Generally, systems include a storage tank for containing purified water, wherein elements of the purification system are attached directly to the storage tank, at its exterior or interior. At the storage tank exterior surface, a mounting plate is attached that contains a sediment filter and a reverse osmosis element. The storage tank interior space contains a mechanical float valve system that uses the amount of purified water within the storage tank to provide a negative feedback system to proportionally control flow of water into the purification system.
