A mobile station and methods are disclosed for diagnosing and modeling site specific effluent treatment facility requirements to arrive at a treatment regimen and/or proposed commercial plant model idealized for the particular water/site requirements. The station includes a mobile platform having power intake, effluent intake and fluid outflow facilities and first and second suites of selectably actuatable effluent pre-treatment apparatus. An effluent polishing treatment array is housed at the station and includes at least one of nanofiltration, reverse osmosis and ion-exchange stages. A suite of selectively actuatable post-treatment apparatus is housed at the station. Controls are connected at the station for process control, monitoring and data accumulation. A plurality of improved water treatment technologies is also disclosed. The modeling methods include steps for analyzing raw effluent to be treated, providing a field of raw effluent condition entry values and a field of treated effluent condition goals entry values, and utilizing said fields to determine an initial treatment model including a selection of, and use parameters for, treatment technologies from the plurality of down-scaled treatment technologies at the facility, the model dynamically and continuously modifiable during treatment modeling.

Anaerobic digester system and method

An anaerobic digester system has a vertically upright vessel, a matrix arranged in the vessel supporting a microorganism biomass thereon, an input for supplying an input slurry of liquid and suspended solids at an upper portion of the vessel above the matrix, a gas output at the top of the vessel for withdrawing gas generated by anaerobic digestion of solids, and an effluent output at the bottom of the vessel for withdrawing liquid and remaining solids. The vessel has a preferred liquid height to diameter ratio of 2 to 1, and is constructed of inert fiberglass-reinforced plastic coated with a translucent blue gel pigment layer for filtering light at wavelengths that promote biomass cultivation. The matrix is formed as an array of panels mounted to a spindle with wheels fixed at spaced intervals along its vertical height, and the panel are made of a polyethylene grass matting providing a high surface area to volume ratio of at least 20 to 1. Gas from the top of the vessel is recycled to the bottom to generate bubbles for mixing the feedstock. The related method of anaerobic digestion includes comminuting input wastes with a slurry grinder into a pumpable slurry 8-10 % by weight solids, and providing as the biomass hydrolytic bacteria, and fermentative bacteria including acetogenic and methanogenic bacteria to produce a methane gas product. Other products include an organic soil additive, bacterial solids plant food, and a filtrate used as plant tonic.

Method for biologically remediating water body and soil comprehensively utilizing resources

The invention discloses a method for biologically remediating a water body and soil comprehensively utilizing resources. The method comprises the steps: (1), determining main pollutants in a selected land area or water body area; (2), selecting to plant and/or cultivate fast-growing herbaceous plants, fast-growing alga, trees, bushes, fungi or microorganisms with high remediation efficiency in the selected land area or water body area; (3), harvesting or collecting the fast-growing herbaceous plants and the fast-growing alga after growing to reach a suitable height or size; (4), concentratedly processing the harvested or collected fast-growing herbaceous plants and the fast-growing alga, and comprehensively utilizing to prevent the pollutants from dispersing; (5), remediating an eutrophic water body by adopting an artificial floating island; (6), remediating a heavy metal polluted water body by confining floating plants; (7), repairing cadmium and zinc polluted soil by mixed-cropping festuca arundinacea and bluegrass; (8), remediating polycyclic aromatic hydrocarbons (PAHs) polluted soil by mixed-cropping alfalfa and italian ryegrass; and (9), extracting and recovering silver from silver-containing wastewater remediation plants.
