Abstract: A water purification apparatus connected to a water system includes a hopper for holding chemical tablets on a perforated bed and an underlying basin. A spray head is detachably connected to the perforated bed and sprays water onto the tablets and parallel to the perforated bed. The basin receives the water through the perforated bed. Because the hopper allows for the use of different spray head designs, the rate at which water is introduced to the tablets, and thus the chemical output, may be modified by replacing one spray head for another having a different number of spray nozzles or having spray nozzles of a different size or shape. Consequently, the hopper of the present invention may be used for delivering the proper concentration of a variety of water treatment chemicals.

Abstract: A liquid sample (104) introduced in a main flow passage (101) is held in a dam portion (105), and a trigger liquid (106) is filled in a trigger flow passage (102). In this state, the trigger liquid (106) is further introduced at desired timing into the trigger flow passage (102) so that the front end portion of the level of the trigger liquid (106) is advanced and the front end portion is brought to be into contact with the dam portion (105).

Abstract: A solid detergent dispenser for use with a dishwashing machine includes a chamber and a lid. The chamber is configured and arranged to receive a solid detergent having a particular composition. A water inlet receives water from a water source, and the water flows through a tunnel into the bottom of the chamber. The chamber is flooded with water from the bottom to ensure relatively constant erosion of the solid detergent, which ensures that a relatively constant concentration of the solid detergent is used in the dishwashing machine. A water outlet allows water to flow out of the chamber into the dishwashing machine. The water must flow into the chamber faster than it flows out of the chamber to ensure that the appropriate amount of dissolution of the solid detergent occurs. The only valve used in the preferred embodiment is a valve to control the amount of water flowing into the water inlet.

Abstract: Embodiments of the present invention are directed to a fluid dispenser for dispensing landscape maintenance fluids or the like which contain products such as fertilizers, herbicides, and pesticides. The fluid dispenser injects the fluids directly into the mainstream of an irrigation system. The dispensing system operates by shunting a portion of the main irrigation water stream through a bypass to the dispenser containing the product to be dispensed. The water dilutes the product to be applied, and is injected back into the main irrigation stream by the back pressure of the irrigation system. When the irrigation is completed, the fluid flow in the main irrigation stream is reduced or terminated and the pressure drops. After the pressure drops, the fluid ceases to be diverted to the container, and the main irrigation stream drains.

The system and method only needs diluent line pressure in at least one embodiment. Further, the method and system controls access to the batch quantity so that multiple batches are not unintentionally extracted. The method and system can be used with vending machines placed on site.
