The present invention is directed to an intelligent water management irrigation system for monitoring the total water usage for a billing site and preventing cumulative water usage from exceeding a water budget by adjusting the amount of water used for irrigation. Irrigation zone priority values are selected for each irrigation zone that specify a percentage of the full water need that the foliage in the zone can survive and are saved in an intelligent water management irrigation (IWMI) controller. The IWMI controller receives water usage information originating from a property's water meter and compares the measured water usage with the allowable water budget. Water usage is tracked separately for the household use and landscape use (irrigation). Prior to each irrigation cycle, the IWMI controller estimates the amount of water that will be needed by the landscape and for household use during the remainder of a billing cycle; household use is given precedence over landscape use. If the water budget will support both, irrigation can proceed normally. If the budget will not support both, the IWMI controller estimates the amount of water needed for the remainder of the billing cycle if only a priority watering amount is allocated for each landscape zone. If the water budget will support priority irrigation, landscape watering can proceed in priority irrigation mode. If the water budget will not support priority irrigation watering, the irrigation cycle is skipped and the water usage estimations are recalculated prior to the next irrigation cycle.

A complete storm water management system and process which performs both drainage and treatment tasks and incorporates a wetlands water treatment system. This system creates an infrastructure, flow control which is multi-level and multi-stage. This system incorporates a self-contained wetlands treatment system. This is a modular system which includes three or more linear chambers through which the storm water or other influent passes and is cleaned. The influent which flows into a storm drain, curb inlet, or inflow pipe into the system is directed first into a screening type catch basin inset filter within the first chamber of the system. The wetlands chamber is composed of one or more modular segments which may be made in various depths, lengths and widths. The influent is treated within the first chamber before it passes out of this chamber into the incorporated wetlands system. The water flows through the wetlands chamber where it is further filtered and decontaminated through both an aerobic and anaerobic process. In situations of high runoff there is a bypass component which runs directly from the first chamber and bypasses the wetlands chamber dumping the pretreated water into the discharge final chamber. This system is fitted with a variable level treatment component designed in such a way to offer variable discharge rates and thus vary the level of treatments over a wide range of flow rates. The system can be placed underground, and below concrete, such as in parking lots or park areas.

The invention discloses a fuel cell anode water management system and a control method, and belongs to the technical field of proton exchange membrane fuel cells. Aiming at the problem of anode watermanagement in the operation process of a proton exchange membrane fuel cell, the scheme provided by the invention can realize two functions of water removal and humidification, and liquid water separated from a baffle in a gas-water separation device in the water removal process is stored and supplemented to an ejector when the fuel cell membrane is dry and needs to be humidified. Liquid water inthe electric pile tail gas is fully recycled, so that the environmental adaptability of a humidifying system to a water shortage condition and a low-temperature condition is improved. Liquid water issucked into a mixing chamber through high-pressure hydrogen and the ejector, and extra system power consumption increased by humidifying devices such as an atomizing nozzle and an ultrasonic atomizeris avoided.

A compact solid source of hydrogen gas, where the gas is generated by contacting water with micro-disperse particles of sodium borohydride in the presence of a catalyst, such as cobalt or ruthenium. The micro-disperse particles can have a substantially uniform diameter of 1-10 microns, and preferably about 3-5 microns. Ruthenium or cobalt catalytic nanoparticles can be incorporated in the micro-disperse particles of sodium borohydride, which allows a rapid and complete reaction to occur without the problems associated with caking and scaling of the surface by the reactant product sodium metaborate. A closed loop water management system can be used to recycle wastewater from a PEM fuel cell to supply water for reacting with the micro-disperse particles of sodium borohydride in a compact hydrogen gas generator. Capillary forces can wick water from a water reservoir into a packed bed of micro-disperse fuel particles, eliminating the need for using an active pump.
