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 specific resistance value adjustment apparatus includes: a hollow fiber membrane module; a module passing pipe which passes through the hollow fiber membrane module; a bypassing pipe which bypasses the hollow fiber membrane module; a liquid discharge pipe which communicates with the module passing pipe and the bypassing pipe through a joint portion; a first flow rate detection unit which detects a first flow rate of a liquid flowing to at least one of a liquid supply pipe and the liquid discharge pipe; a control valve which opens and closes the module passing pipe; and a control unit which sets an opening degree of the control valve in response to the first flow rate detected by the first flow rate detection unit.

The invention relates to a method for reducing emission of ammonia from a livestock housing. The method comprises applying a composition comprising a compound that restrains ammonia volatilization onto freshly excreted manure by an animal in the livestock housing. Because the compound is deposited onto freshly excreted manure, ammonia volatilization is tackled at the source, rather than at a later moment, e.g. in a manure pit, when contact of faeces and urine, and therefore the conversion of urea to ammonia under the influence of urease has already led to volatilization of ammonia.

A cartridge and a method for enriching drinking water with silicon are provided. A cross-linked silicic acid is used, which can be mixed with a cation exchanger that is preferably loaded with hydrogen and/or with alkalizing agents and/or with activated carbon. Silicon can be released into the water via the silicic acid.

A multifunctional additive including a biochelant and a sulfide scavenger. A method of servicing a cooling tower including contacting an industrial water present in the cooling tower with an additive comprising a biochelant and a sulfide scavenger. A method of servicing a wellbore including contacting an industrial water produced from the wellbore with an additive including a biochelant and a sulfide scavenger.

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.

The present disclosure includes compositions and methods for filtering a liquid, e.g., water. The compositions herein may include a filter aid comprising a filter medium and packaging having at least one water-soluble portion. When the filter aid is introduced into the liquid to be filtered, the water-soluble portion(s) may dissolve or otherwise degrade in order to expose the filter medium to the liquid.
