The supercoil filtration unit further includes a feed inlet, a permeate outlet, and a retentate outlet. The feed inlet is disposed upon the outer coil and in fluid communication with a first interior volume. The permeate outlet is disposed upon the outer coil at a location distant from the feed inlet and in fluid communication with a second interior volume. The retentate outlet is disposed upon the outer coil at a location distant from the feed inlet and in fluid communication with the first interior volume.

A rotary fluid filter including a filter body rotationally mounted within a housing. The housing having a front cap having a main fluid inlet and a backwash outlet, a rear cap having a main fluid outlet and a backwash inlet. The filter body having a front face, a rear face, and a plurality of fluid flow passages each extending through the filter body between the front face and the rear face and having a filter received in each fluid flow passage. The filter body operable to rotate with in the housing such that, for each fluid flow passage, as it is aligned with the main fluid inlet a main fluid is received therein, as it is aligned with the main fluid outlet the main fluid is discharged therefrom, and as it is aligned with the backwash inlet and the backwash outlet a backwash fluid is received therethrough.

Devices and methods associated therewith for facilitating movement, removal and/or installation of components from treatment units (e.g., water treatment units and wastewater treatment units). The treatment unit can take the form of a granular media filter (e.g., upflow filter, downflow filter or bi-flow filter) or a sludge collection basin. One preferred device is one or more floats facilitating safe removal of components of a treatment unit. The float(s) can be operably associated with an air scour system of a water filter to remove the air scour system from a granular media filter bed. The float(s) can be operably associated with a collection grid of a sludge collection container facilitating safe removal of the collection grid from the sludge collection container. Another preferred device is a flexible piping/conduit operably connected to a pressurized air source and an air scour system to assist in removal/installation of the air scour system.

A filtration media, system and method to passively remove phosphorus and coliforms from wastewater streams is provided. The filtration media system allows wastewater to enter via an inlet toward a diffusor, a filtration media and a filtration media support. The filtered wastewater exits through an outlet. In one aspect, the filtration media broadly comprises sand, activated alumina, peat moss or lime, or any combination thereof. In an exemplary embodiment, the dephosphatation media may further comprise about 20-65% filtration grade sand, about 7-14% granular activated alumina, about 25-50% peat moss and about 5-20% dolomitic lime. The filtration media system may be used in a wastewater treatment method to passively remove phosphorus and coliforms from sewage streams. The dephosphatation media system may be used to passively treat domestic, industrial and commercial sewage streams.

The present invention solves the problem of environmental pollution created by animal waste and converting animal waste to reusable water in the earth. The invention does this by a device that is capable of receiving animal waste and breaking down the waste into different components by the help of a decomposing catalyst such as a septic pack, filtering the resulting solution and finally producing a filtered liquid that enters the earth being cleansed by the process. The present invention comprises a filter device, a tank unit, a filter unit, a first opening positioned on a top surface of the tank unit; a second opening positioned on a bottom surface of the tank unit; wherein the tank unit is capable of receiving animal waste through the first opening; at least one hole at a bottom surface of the filter unit; wherein the tank unit is placed over the filter unit.

A fluid management system including an inlet configured to receive pre-processed fluid is provided. The system includes a filtering apparatus configured to remove contaminants from the pre-processed fluid. The filtering apparatus includes a plate having a first opening. A first manifold pipe is disposed on the plate and includes one or more perforations and a second opening at least partially aligned with the first opening. A second manifold pipe is disposed on the plate and includes one or more perforations. Filter media is disposed between the first manifold pipe and the second manifold pipe and is configured to separate the contaminants from the pre-processed fluid. The system also includes an outlet coupled to the second manifold pipe to receive processed fluid from the filtering apparatus.

The present invention provides a portable high throughput liquid filter system.

A mobile microalgae harvesting apparatus is disclosed. In one embodiment the mobile microalgae harvesting apparatus includes a harvesting boom coupled to a harvesting vessel, where the harvesting boom skims a microalgae mixture of microalgae and water from a surface of a body of water down to a predetermined depth below the surface. In the embodiment, the mobile microalgae harvesting apparatus also includes a separator aboard the harvesting vessel that separates water from the microalgae mixture and a microalgae collector that collects microalgae from the separator, wherein the microalgae collector deposits the collected microalgae on a transfer vessel coupled to the harvesting vessel. A mobile microalgae harvester and a system for harvesting microalgae are also disclosed.

Systems, devices, and methods for providing nutrient removals in an up flow filtration storm water system for treating water to very high clean levels using filtration media. A filtration media can be supported by a screen above a floor in a vault allows for incoming storm water to pass into a void space above the floor into the screen and filtration media and then out an outlet to the vault. The filtration media can include recyclable and/or natural particles. Layers of river rocks can be placed on top of and below the filtration media. The captured debris can drop to the floor. The long lasting filtration media can be cleaned by being backwashed.
