An algae treatment device of the present invention is installed in a ship or a barge and selectively destroys only the air-sacs of algae by discharging high-voltage micro pulses into waters of interest in which green tide or red tide has occurred. Thus, the algae treatment device can efficiently solve green tide or red tide by treating algae using a minimal amount of chemicals, or none at all.

A system for separating solids from a fluid mixture includes a vessel including a first chamber to receive a solid-laden fluid mixture, and a second chamber to receive liquids separated from the solid-laden fluid mixture. In certain aspects, at least one eductor is disposed in the first chamber to flow the solid-laden fluid mixture out of the first chamber. In certain aspects, an auger is disposed in the first chamber to move at least solids of the solid-laden fluid mixture out of the first chamber.

An insert designed for use with a protein skimmer is disclosed. The insert includes one or more tubes that define an opening with a diameter. This diameter is designed to be smaller than the protein skimmer neck's diameter. The one or more tubes are insertable and retained by the protein skimmer neck to adjust the effective diameter of the protein skimmer neck's opening.

An apparatus and a method for treating saltwater and removing chlorine in water to make a variety of sodium-based byproducts and chlorine gas is disclosed. The apparatus comprises a feed tank for receiving water. The feed tank is coupled to a plurality of Radio frequency (RF) chambers. Each of the RF chambers comprises an inlet and an outlet. The outlet is coupled to a treated water effluent manifold. Further, each RF chamber is coupled to a vacuum manifold. Each RF chamber comprises a recirculation pipe to pump water back into the feed tank. The RF chamber comprises a RF system used for bombarding RF energy at predefined frequencies on the water in order to liberate chlorine isotope. Additionally, the RF system bombards RF energy to stretch hydrogen bond in the saltwater to a point of breaking a molecule by applying low pressure. The hydrogen bond captures chlorine. Subsequently, the water is sent through the outlet to the treated water effluent manifold.
