A water quality management system for a water installation containing water. In some embodiments, the system includes a water quality measurement module adapted to monitor the water quality of the water in the water installation and to send water quality information to a controller; a chemical dispensing module adapted to dispense chemicals directly into the water installation in response to signals from the controller; and a communication mechanism configured to provide communication among the controller, the water quality measurement module, the chemical dispensing module and a user.

A chlorinator device for chlorinating water to a predetermined chlorination level with chlorine from a source of chlorine. The chlorinator device has an injector that creates a vacuum as water passes through the injector to draw chlorine from the source of chlorine into the injector and an adjustable chlorine flow meter positioned in fluid communication with and between the injector and the source of chlorine to adjust the flow rate of chlorine entering the injector to a predetermined rate.

The present invention is a water purification system and method including a treatment tank with a water inlet, a chlorine source, and a heating element; at least one storage tank with at least one treated water outlet between the treatment tank and the storage tank(s) through which treated water passes therebetween, and a final water outlet(s) through which treated water leaves the system for the benefit of the end user. A power source powers all elements that require power, such as the heating element.

A method and system for the remediation of the water of an aquatic facility using an integrated process control system to control a mixed halogen-based treatment including chlorine dioxide and a free halogen. The integrated process control system provides versatile control the chlorine dioxide concentration using accelerated side-stream generation of chlorine dioxide. The remediation can occur continuously, and/or intermittently using a daily remediation cycle or a rapid recovery shock.

Livestock may be managed by a variety of systems, processes, and techniques. In particular implementations, the properties of water may be monitored by automated techniques and treated water may be provided to animals. In certain implementations, sick, or potentially sick, livestock may be provided with treated water to improve their health. The automated techniques may include monitoring the movements and/or water consumption of the livestock and predicting which ones may be sick based on their movements and/or water consumption. In some implementations, a water trough may contain multiple segments. The water properties in the segments may be maintained at different states.

A mobile device reads a test strip to determine a chemical condition of a liquid or a user inputs a treatment plan into the mobile device. The mobile device transmits the determined chemical condition or the input treatment plan to a liquid treatment system which treats the fluid in response to the determined chemical condition or the input treatment plan.

Provided is a water recovery system and a water recovery method whereby, in water recovery using a reverse osmosis membrane from water to be treated containing organic matter, it is possible to also suppress slime contamination on the secondary side of the reverse osmosis membrane. A water recovery system includes: a reverse osmosis membrane treatment device which separates water to be treated containing organic matter into permeated water and concentrated water with a reverse osmosis membrane; iodine-based oxidizing agent adding piping which adds an iodine-based oxidizing agent to the water to be treated; and permeated water piping as a supply means for supplying the permeated water as water to be treated in a water utilization system.

Biocide can be controllably added to a feed stream for a membrane. The membrane can separate the feed stream into a purified permeate stream and a concentrate stream containing contaminants from the feed stream. In some examples, a charge neutral biocide is introduced into the feed stream at a first addition rate. The concentration of the charge neutral biocide in the permeate stream is measured to provide a measured concentration of the charge neutral biocide in the permeate stream. The addition rate of the charge neutral biocide can be adjusted based on the measured concentration of the charge neutral biocide in the permeate stream to introduce charge neutral biocide into the feed stream at a second addition rate different than the first addition rate.
