Described herein are attached growth reactor systems which increase nitrifying bacteria biomass through a variety of means during warm weather. As a consequence, the attached growth reactor system contains sufficient nitrifying bacteria biomass to remove ammonia from wastewater in cold to moderate climates. In one example, there are two attached growth reactors into which wastewater is distributed discontinuously. Specifically, wastewater is transferred to the first attached growth reactor for a first period of time and then is transferred to the second attached growth reactor for a second period of time during warm weather which effectively doubles the nitrifying bacteria biomass in the system. During cold weather, approximately half of the wastewater is applied to each reactor simultaneously.

The present disclosure provides a block coupler for connecting block to block for septic tank and water treatment facility. The block coupler comprises a body having a flow path therein; an inflow part having an inflow hole formed on one side of the longitudinal ends of the body so as to communicate with the flow path; an outflow part having an outflow hole formed on the other side of the longitudinal ends of the body having the inflow part so as to communicate with the flow path; and a connecting part provided at the outer end of the body having the inflow part so as to prevent the body coupled to the block from being separated.

Aerobic wastewater treatment systems may include a treatment tank having a tank interior. An aeration chamber may be provided in the tank interior. A wastewater inlet conduit may be disposed in fluid communication with the aeration chamber. An air inlet conduit may be disposed in fluid communication with the aeration chamber. A diffuser may be provided in the aeration chamber. The diffuser may be disposed in pneumatic communication with the air inlet conduit. A clarifier in the tank interior may include a vertical outside clarifier wall portion. An inside clarifier wall portion may be disposed at an acute angle to the outside clarifier wall portion. A clarifier interior may be formed by and between the outside clarifier wall portion and the inside clarifier wall portion. A clarifier inlet may establish fluid communication between the aeration chamber and the clarifier interior. An effluent outlet conduit may be disposed in fluid communication with the clarifier interior. Aerobic wastewater treatment system fabrication methods are also disclosed.

A portable, personal apparatus for treating drinking water comprises a generally tubular or cylindrical filter housing containing filtration media and water-permeable screen or mesh or felt or membrane or netting layer at the top and bottom ends of the filter. The design of the apparatus involves the bottle exterior and interior contouring to the filter and enables the efficient and rapid gravity flow of water in through the filter. The apparatus may be configured such that water is first passed through a top reservoir designed to receive water, followed by a porous mesh, followed by granular filtration and antimicrobial media agitated by turbulent motion of influent water, followed by a porous mesh before reaching a durable and reusable water containment vessel.

The present invention relates to an apparatus for manufacturing oxygen water or hydrogen water. The apparatus for manufacturing oxygen water or hydrogen water is configured such that oxygen or hydrogen generated from a device for generating oxygen and hydrogen by electrolyzing water is supplied to water using a fluid pump for manufacture of oxygen water or hydrogen water. The apparatus is configured to easily, quickly, and effectively manufacture oxygen water or hydrogen water in a plastic water bottle by dissolving high purity oxygen or hydrogen in source water in the bottle directly. Accordingly, by drinking oxygen water or hydrogen water manufactured thereby, fresh oxygen is supplied to the body, and hydrogen is also supplied to the body and removes harmful reactive oxygen species or reactive carbon species, thereby enabling a healthy life.

A wirelessly controlled device for atmospheric water generation is provided. The device comprises an atmospheric water generator for generating filtered potable water and a wireless external control system. The wireless external control system comprises one or more display presentation pages for displaying a plurality of operating parameters for the atmospheric water generator, including content display with a variety of operation parameters and historical water collection data for operation of the atmospheric water generator. The wireless external control also has one or more display pages configured for user input for a user to select one or more water generation parameters for operation of the atmospheric water generator. Once the device is directed by the wireless external control system to generate water, the device is capable of automatic water generation until the device fulfills the one or more set water generation parameters.

A round meander septic tank includes an elongate baffle that divides the interior space of the tank into two semicircular chambers. Untreated wastewater is introduced to the first chamber through an inlet located near the first end of the baffle. The wastewater flows through the first chamber to a portal at the second end of the baffle and passes through the portal into the second chamber. A wastewater outlet from the tank is located in the second chamber near the first end of the baffle. Wastewater passing through the portal flows through the second chamber to the outlet and out of the tank. The baffle and the shape of the septic tank increase the distance that the wastewater must flow from the inlet to the outlet as compared to a rectangular meander tank with a single baffle.

A portable, personal advanced-oxidation water treatment system based on ozone and a catalyst such as titanium dioxide that can cycle and purify water to make it potable by removing organic contaminants. The unit can be used for long periods of time without having to replenish the active portions. The unit can be carried in a backpack or in a vehicle. Fresh water is typically loaded into the unit, and the unit is cycled until the water is pure enough to drink. A battery is used to produce ozone and to cycle the water through a reaction vessel and can optionally be charged with a small solar panel The unit can also be powered directly from a vehicle.

The present invention is a wastewater treatment system utilizing a recirculating filter system comprising sand, gravel, or synthetic media. Septic effluent is continuously, or approximately continuously, dosed under pressure to the treatment media through pressure compensating drip irrigation emitters. The dosed effluent is treated and dispersed into a dispersal field using double coiled distribution lines that can alternate flow through emitters to rest the dispersal field. The double coil dispersal lines allow more emitters per unit area allowing treatment of the effluent more slowly and effectively.
