An ammonia stripper (32) and method for stripping ammonia from ammonia-containing water is described, comprising an ammonia-containing water inlet (56), a steam inlet (70), and a forced air inlet (82), and an ammonia-containing gas outlet (36) and a wastewater outlet (72). The steam and air contact the ammonia-containing water in counter-flow to release ammonia from the ammonia-containing water. The ammonia stripper further comprises a steam and air mixing duct (200) shaped to create turbulence in the steam and air flow to promote mixing of the steam and air flow prior to contacting the ammonia-containing water. Also described is an ammonia stripper and method comprising a precipitation unit for precipitating solids from the ammonia-containing water prior to the inlet, and an ammonia stripper and method comprising a steam flash vessel for generating steam from the wastewater produced by the ammonia stripper for recycling into the ammonia stripper. Further described are thermal destructors for destroying ammonia in ammonia-containing gas from an ammonia stripper; and a method of removing ammonia from ammonia-containing gas wherein ammonia-containing gas is drawn from the ammonia-containing gas outlet and returned into the ammonia stripper to mix with the forced air entering the ammonia stripper.

Disclosed is a method of treating a clinical analyser wastewater stream containing a first concentration of azide ions in solution, comprising at least the step of passing the clinical analyser wastewater stream through an anodic oxidation chamber having one or more anodic oxidation cells to provide a post-chamber treated water stream, said treated water stream having a second concentration of azide ions in solution that is less than the first concentration of azide ions in solution. A clinical analyser treatment apparatus comprising an anodic oxidation chamber having one or more anodic oxidation cells able to reduce a concentration of azide ions is also disclosed.

Methods and systems for converting ammonium waste streams into certifiably Organic ammonium salts having a variety of uses in greenhouse gas-reducing activities are herein described. The resulting ammonium salt compositions can be used to enhance crop yield.

A system for treating and/or recycling gray water includes a first receiving tank for gray water, a second receiving tank for treated water and a fluidic treatment circuit between the first and second receiving tanks. The first receiving tank includes an element for oxygenating the water in the first receiving tank and a system adapted to deliver enzymes into the first receiving tank. The fluidic treatment circuit includes a filtration unit, a microfiltration unit including at least one microfilter, a disinfection unit and a membrane ultrafiltration unit.

Method for the production of organic fertilizer comprising providing an organic source of ammonia gas, in particular air contaminated with ammonia gas, directing the air contaminated with ammonia gas through water and forming an ammonium hydroxide solution converting the ammonium into nitrate, dosing, under the control of a control system, the ammonium hydroxide solution to a recirculation stream from a second bio-reactor with bacteria suitable for converting the supplied ammonia into nitrite and nitrate. The amount of ammonium water fed by the control system to the acidic nitrate solution from the second bio-reactor depends on one or more measured pH values in the device.

A process for producing a calcium phosphate reactant, according to which: in a first step, use is made of a source of calcium and a source of phosphate ions in water, in a molar ratio that is adjusted so as to obtain a Ca/P molar ratio of between 0.5 and 1.6, and the source of calcium is reacted with the phosphate ions at a pH of between 2 and 8, in order to obtain a suspension (A) of calcium phosphate, and in a second step, added to the suspension (A) are an alkaline compound comprising hydroxide ions in order to set a pH of more than 8 and an additional source of calcium in order to obtain a suspension (B) of calcium phosphate reactant having a Ca/P molar ratio of more than 1.6. A calcium phosphate reactant obtainable by such a process.

An ultrapure water (UPW) generation and verification system can include a cleaning chemical station, a cleanup column, a conductivity verification station, and a holding reservoir, in fluid communication with one another. The cleaning chemical station can be configured to selectably permit a flow of water to pass therethrough to the cleanup column or to block the flow of water and instead deliver a cleaning chemical to the cleanup column. The conductivity verification station can be configured to selectably perform at least one of the following: permit water to flow from the cleanup column to the holding reservoir; direct fluid to waste; or test the conductivity of the water for a purity level.

A water softening system includes a water feed channel through which water to be treated flows, and a crystallization unit that causes a metal ion contained in the water to be treated to precipitate. Further, the water softening system includes a separation unit that separates the water to be treated having passed through the crystallization unit into a crystal obtained through precipitation by the crystallization unit and soft water. Further, the water feed channel is configured so that at least a part thereof functions as a feed channel being a pressure application system in a substantially sealed state, and the crystallization unit and the separation unit are connected to parts corresponding to the feed channel being a pressure application system in a substantially sealed state in the water feed channel.

An ultrasonification system is provided. The ultrasonification system includes a duct having a proximal end and a distal end, and a vibrating head disposed within the duct near the proximal end thereof. A fluid enters the duct from the proximal end and flows toward the distal end. Related apparatus, systems, techniques, and articles are also described.

The present disclosure relates generally to systems, apparatuses, and processes for preparing a gas-infused additive that is useful within gas-floatation systems configured to separate solids and/or oils from a liquid within a suspension. The gas-infused additive can be injected into systems having a floatation consolidator to provide additional dissolved gas to the system. Advantageously, the processes and apparatuses disclosed herein are compatible with systems and processes having a single injection point for the addition of an additive or gas, without requiring substantial modification or reconfiguration of the system. The inventions described herein additionally teach that the gas-infused additive can be prepared and injected downstream of any pump present within the system, thereby protecting the pump from the damaging effects of cavitation corrosion and similar phenomena.
