A hand held shower head configured to deliver a continuous dose of water dispersed treatment from a water disintegratable treatment source, the shower head including: a hollow body having water inlet opening and water outlet, the water outlet defined by a perforated plate, and a mesh formation disposed within the hollow body between the water inlet opening and the perforated plate, wherein the water inlet opening, hollow body and perforated plate are configured to create in use a pressurised turbulent water flow within the hollow body prior to exiting through the perforated plate, whereby a water disintegratable tablet treatment source introduced into the hollow body prior to use, is then agitated by the turbulent water flow against the mesh in an abrading manner and thereby dispersed into the water flow exiting the perforated plate. A water disintegratable tablet comprising emulsifier, thickening agent, surfactants, oil and rheology modifier is also disclosed.

A swimming pool chemical dispenser includes a main body having an accommodating cavity formed therein for storing chemical tablets, an upper cover which covers the upper opening of the main body, and a tablet clamp having a clamping end penetrating downward through the upper cover and abutting against the chemical tablets. The tablet clamp is provided with scales. The tablet clamp descends along with the dissolution of the chemical tablets and the amount of residual chemical tablets can be visually and reliably determined from the scales on the tablet clamp for timely refill. The tablet clamp is placed on the main body, thus making it convenient for the user to replace the chemical tablets bare-handed without touching the chemical tablets, which is much safer and more environmentally friendly.

A first filter material for water treatment comprising a first granulate containing calcium carbonate and a second granulate containing magnesium oxide, wherein the first and the second granulate each independently having a bulk density of 1.00 to 1.40 t/m.sup.3; a second filter material for water treatment comprising 55 to 85 wt. % of a first granulate containing calcium carbonate and 15 to 45 wt. % of a second granulate containing magnesium oxide, in each case based on the sum of the amounts of the first and the second granulate; a method for manufacturing the filter material; a filter containing the filter material; a use of the filter material for treating water; and a water treatment method are described.

The present invention relates to a family of very stable aqueous hypochlorite products and methods for reducing the self reactivity of Ca(OCl).sub.2.

The present invention provides a kind of an integrated sewage treatment equipment for paper mill, which belongs to the technical field of sewage treatment, includes a box body, and the box body is arranged a water injection gap on the upper part at one side, the bottom of the box body is connected with a drainage pipe, and a filter assembly is arranged inside the box body movably, and the inner wall of the box body is equipped with a limit component which provides guidance for the movement of the filter assembly; the filter assembly includes several concentrically arranged annular plates, and two adjacent groups of annular plates are connected by a netting. The bottom of the annular plate is equipped with a chemical dosing component, and the inner side of the innermost annular plate is equipped with an adapter sleeve.

The invention provides a device with a steam function, wherein the device includes a water supply opening, a scale inhibitor dosing element, a flow control device, a heating unit, a scale collector element, and a water processing unit. Further, the flow control device provides a fluid including water to flow from the water supply opening via the heating unit to the water processing unit; the scale inhibitor dosing element provides a scale inhibitor to the water at a location in the heating unit and/or upstream of the heating unit; the heating unit includes heating the water in a heating mode and for converting the water into steam in a steam formation mode; and the scale collector element is arranged downstream of the heating unit and upstream of a flow restriction, wherein the scale collector element includes collecting scale particles from the fluid flowing through the scale collector element.

Disclosed herein is a liquid pod comprising a liquid composition comprising at least two of a Solvent A, a Solvent B, an Active, a Modifier, and an Adjuvant, wherein the water treatment liquid composition is disposed within a packet comprising a water-soluble polymer film.

A non-dissolvable immersible dispensing puck in the shape of a dissolvable halogen puck when the dissolvable halogen puck is in an undissolved state with the non-dissolvable immersible dispensing puck physically interchangeable with a dissolvable halogen puck when placed in a dispenser for normally holding only a set of halogen pucks to enable a single dispersant dispenser to be converted to a dual dispersant dispenser without changing the structure of the single dispersant dispenser by placing a dispenser within a dispenser wherein only one of the dispensers may be provided with adjustable water ports.

A system for sanitizing a drinking water-carrying device includes a filter candle that can be installed in a filter head. The filter head has one inlet and one outlet, and the system includes a sanitizing cartridge which can replace the filter candle. The sanitizing cartridge includes a sanitizing agent that can be flushed into the drinking water-carrying device via the filter head.

Chemical dispensers are provided that include a hollow body member including a bottom end configured to be disposed below a waterline and a top end configured to be disposed above the waterline. The hollow body member defines an interior space disposed between the bottom end and the top end that is configured to accept, through the top end, and hold therein a dissolvable chemical. The dispenser includes a buoyancy member surrounding the hollow body member and configured to provide buoyancy to the dispenser when placed in a body of water such that a first portion of the interior space remains above the waterline and a second portion of the interior space submerges below the waterline. An opening in the hollow body member allows sufficient water flow into the interior space below the waterline such that dissolution or partial dissolution of the dissolvable chemical below the waterline occurs.
