A system for on-site production of chlorine dioxide and other sanitizing solutions is disclosed which includes an activation chamber to mix concentrated activator and base solutions. The resulting solution from the activation chamber is then mixed with water in a two-stage measurement/mixing vessel to create a ready-to-use cleaning solution. A drainage system is employed to transfer the ready-to-use cleaning solution into a reservoir for on-site use.

A teat sprayer for use in dairy applications is described that uses an articulated arm and system to deliver a spray to a teat and move between multiple dairy animals. In one aspect the dairy animal teat treatment apparatus, comprises a spray inlet, a spray nozzle, a flow path extending between the spray inlet and the spray nozzle, and an articulated arm conveying the spray nozzle, movement of the articulated arm driven by an actuator. Articulated arm movement may be between a retracted position in which the spray nozzle and articulated arm are retracted and an extended position in which at least part of the articulated arm and spray nozzle thereon is extended, moving the spray nozzle to a position configured to be about an animal's udder. In a further aspect, the apparatus, comprises an animal sensor positioned generally above and behind an animal bail and directed generally downwards configured to sense the presence of an animal in the animal bail; and a controller configured to actuate spraying of the animal's teats from spray nozzle extension and retraction in response to a signal received from the sensor. The apparatus may act to reduce cost through reduced numbers of treatment apparatus and/or lower labour costs and expenses; increase accuracy/efficiency through automation and speed of treatment; address issues associated with the inconvenience/space constraints in dairy platform configurations; and minimise the number of sensors required and position these sensors away from the animal bail.

A sprayer system including a wand, a rotary arm, a motor, a housing, a support, and a controller or control panel. The wand has a nozzle at one end. The rotary arm rotates around a first axle, and is connected at a distal end through a bearing to an opposite end of the wand. The housing covers or encloses a part of the wand, the rotary arm, and a rotatable ring through which the wand passes. The motor drives rotation of the rotary arm. The support mechanically supports the housing. The controller/control panel controls rotation of the rotary arm. The wand, the rotary arm and the ring are configured so that rotation of the rotary arm causes the nozzle to move in a circular, elliptical and/or oval pattern. Methods of making and using the sprayer system and software for controlling the system are also disclosed.
