A potable water producing system for disposition at a salt water body and methods of producing potable water are provided. The system includes a wave energy conversion system (AWECS) and a portable filtration system. The AWECS forms a floating articulated barge having an onboard desalination system including reverse osmosis membranes. The filtration system is a sand filter residing on a damping plate submerged in the salt water body and filters the adjacent salt water for providing filtered salt water to the onboard desalination system. Wave action on the articulated barge provides energy to pump and pressurize the filtered salt water from the sand filter to the reverse osmosis membranes to produce potable water. The wave action on the articulated barge effects shaking of the reverse osmosis membranes, thereby rendering them self-cleaning. The potable water can be used for various applications, e.g., bottling, replenishing aquifers, ground and/or aquifer remediation, irrigation, etc.

The present invention provides a system for prevention of adhesion of organisms in water to a substrate in contact with the water, wherein the substrate and the water flowing around the substrate form together a treated region, comprising a generator for producing electromagnetic wave having a time varying frequency, in electrical connection with a first excitation site of the treated region and with an avalanche current suppressor having its another terminal connected with a second excitation site of the treated region. A selected voltage is applied to the generator such that the generator is triggered to produce the electromagnetic wave capable of inducing an avalanche current to shock or kill the organisms. The invention also provides a method for prevention of adhesion of organisms in water to a substrate in contact with the water.

Provided is a flowing-water sterilization system that includes a flow channel for passing seawater to be sterilized, and a light source emitting ultraviolet light to irradiate the seawater passing through the flow channel, wherein the light source includes a light-emitting diode that emits light not including infrared light. The light-emitting diode may emit ultraviolet light that has a wavelength of not less than 250 nm and not more than 350 nm and does not include light with a wavelength of not more than 200 nm. The system may further include a cooling unit for cooling the light source.

A device for treating harmful algal blooms using modified clay includes a power system, a screw conveying storage bin storing and conveying modified clay to a mixed flow system, the mixed flow system that continuously disperses the modified clay in water which is pumped in in site and endowed an impulse so that an adjustable turbulence is formed to instantly adopt the fed powder and then make sure the slurry uniform and ripened, a high-pressure sprinkling system for pressurizing a ripened modified clay slurry and sprinkling the slurry onto the surface of the bloomed water, and a central control system that controls the whole auxiliary device.

A method for eliminating harmful algal blooms through optimized utilization of a modified clay method includes building a real-time state index and a standardized value grading system for eliminating a site harmful algal bloom or a harmful algal bloom in accordance with the features of monitored harmful algal bloom organisms and modified clay flocculates; acquiring corresponding grade codes of feature index values of the harmful algal bloom in a to-be-treated water body or harmful algal bloom elimination effect through the real-time site state index and the standardized value grading system; comparing the above grade codes with an expert system to obtain an operation solution for eliminating harmful algal blooms through optimized utilization of the modified clay method. The result is tracked and monitored in real time and the operation solution is optimized and adjusted in time according to the harmful algal bloom elimination effect.
