The at least one tablet is configured to slowly release the septic treatment into toilet water. The at least one tablet may also have a dissolvable color indicator configured to run out at approximately the same time as the dissolvable septic treatment is depleted. An attachment may be provided in the form of an adhesive disc, suction cup, or hangar. An applicator may be used to apply the at least one tablet to an interior surface of the toilet.

The present invention relates a solar-powered, floating, fountain lamp, comprising a light-emitting elements, a fountain housing, and a solar panel, and the fountain housing acts not only as a three-dimensional lampshade for a first light-emitting portion, but also as a floating portion of the fountain lamp, and the fountain housing is substantially formed by a saucer-shaped cabin and a cylindrical lower part that are integratedly connected to each other, in which the saucer-shaped cabin located in an axially upper part of the fountain housing has an outer peripheral surface that is smooth and curved, and the plurality of light-emitting elements each project a light beam in a different direction, and the light-emitting elements projecting the light beams outward the fountain housing form point light sources at a top of the fountain lamp, the point light sources on the top act as a second light-emitting portion, and the light-emitting elements projecting the light beams inward the fountain housing form the first light-emitting portion, and the first light-emitting portion provides uniform lighting through the three-dimensional lampshade formed by outer walls of the saucer-shaped cabin and of the cylindrical lower part that are smoothly connected.

An inline drain sanitizing system, includes: a manifold assembly including an inlet port, an outlet port, and a treatment port, wherein: the inlet port is configured to be couplable to a condensate supply line and receive unsanitized condensate, and the outlet port is configured to be couplable to a condensate drain line and provide sanitized condensate; and a treatment subsystem configured to interface with the treatment port and process the unsanitized condensate to generate the sanitized condensate.

A water softener apparatus comprising a housing having a chamber for accommodating at least one compressed salt block having an elongated block form, the configuration accommodating the compressed salt block within the chamber with its longitudinal axis in a vertical orientation. The water softener apparatus includes a manually detachable front cover enclosing the chamber and a non-touch salt level indicator device arranged in or on the front cover of the housing above the chamber to determine a salt level from an upper end face of the compressed salt block accommodated in the chamber, the non-touch salt level indicator device determining the salt level from the upper end face of the compressed salt block through a wall of the front cover of the housing. The non-touch salt level indicator device is a battery powered device and the water softener apparatus is a non-electric powered water softener apparatus.

A waste treatment includes a package with compartments. A surfactant, an oxidizing agent, and, optionally, a liquid may be disposed within the compartments. The oxidizing agent is within a compartment that does not contain the surfactant or the liquid. A bursting force may unseal a sealed end of each compartment. The liquid flushes the surfactant and the oxidizing agent out of the package into a non-contact agitating toilet. A dual compartment package made with a fluidly disintegrable material may separate the surfactant from the oxidizing agent where the liquid may not be provided. The waste treatment may be mixed with a waste deposited within the non-contact agitating toilet. The package may disintegrate in the presence of the liquid to allow the reactive components to mix. A plurality of waste treatments may be connected. A perforated barrier may separate a first waste treatment from a second waste treatment.

A reactor arrangement for performing, by means of at least one solid reaction member(s), a biological or chemical transformation, or physical or chemical trapping from, or release of agents to, a fluidic media in a continuous process. The arrangement comprises at least one reactor with a cylindrical reaction vessel (11) in which at least one reactor a transformation device (100) has been mounted. The vessel (11) comprises at least one inlet port (30) in the vicinity of its bottom wall (18) and at least one outlet port (40) arranged in the vicinity of its upper end portion. Each inlet port (30) is connected to a fluid supply member (300) configured to be submerged below the fluid surface level in a pool or a pond. The fluid supply member (300) comprises at least one inlet opening (301) configured to continuously supply a fluid from the pool or the pond to the vessel (11). Each outlet port (40) is configured to continuously let out the fluid from the vessel (11) to the pool or the pond via the outlet port (40). Further a method of using the reactor arrangement is provided.

A floating sports equipment pool chlorinating system dispenses a sanitizing chemical into a body of water for sanitizing water. The system includes a sports equipment-shaped housing, possibly shaped as a helmet or ball. The housing has an outer and inner shell arranged in a spaced-apart relationship. The space between the shells is filled with a closed-cell extruded polystyrene foam, like Styrofoam, which enables the housing to float. The inner shell forms a cavity that is sized and dimensioned to receive and retain a sanitizing chemical, such as a chlorine tablet. The shell has a top region that forms a slot, a bottom region that forms multiple outlet holes, a front region that forms a front opening. All the slots, holes, and openings are in fluid communication with the cavity. The top region of shell, has a spherical shape sufficiently large to enable wind to carry the housing across the water.

Provided herein are methods and compositions for water disinfection. The methods and compositions, which can include a peracid and a source of copper ions, are useful for treatment of water contaminated with recalcitrant microbes.
