A method of and system for naturally treating sewage suitable for residential dwellings on land which will not support a conventional septic tank and drain field are disclosed. The system includes a conventional septic tank, a rock/plant filter, a dosing chamber, a shallow horizontal flow pulsed planted aggregate filter, and an effluent holding tank.

A process (10) for treating sulphate-containing water (28) includes feeding the water into a biological sulphate reduction stage (12) containing a complex carbon source (18). The water is subjected to biological sulphate reduction in the presence of an electron donor source, thereby to reduce sulphates in the water to sulphides and to produce alkalinity. The complex carbon source is contacted with water containing higher sulphide and alkalinity concentrations or levels than the sulphate-containi...

A system and method for removal of uranium and other contaminants from aqueous solution, utilizing live algae, are described. The system includes a bioreactor, in which a reaction mixture of live algae, preferably photosynthetic algae, and contaminated solution are introduced; a means for introducing carbon dioxide gas in the reaction mixture; a means for exposing the reaction mixture to light; means for mixing and impelling the reaction mixture; and means for separating out algae from remediate...

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, c...

A self cleaning filter for aqueous media such as sewage effluent which comprises a ventilated bed of discrete filtration material such as particulates, finely ground or shredded non-oil plastic materials, clay particulates, ground zeolite, diatomaceous earth powdered activated carbon, short fibre carbon and fine crushed charcoal, in which is dispersed a population of living organisms such as worms, insects, mothfly larvae, collembola, crustaceans and mites, which organisms have the ability to ma...

A process is described for dewatering a water-containing material by mixing sphagnum plants into the material as a structural element, and that the mixture thereafter is subjected to a drying process. By mixing sphagnum plant into to such water-containing materials, and thereafter by dewatering the material, traditional processing methods such as composting and incineration of such materials will be much improved.

The present invention provides a water plant treatment system in which the nitrogen and phosphorus components and other contamination substances are removed from the water which has been treated biologically by the conventional system. The water plant treatment system according to the present invention includes a distribution section for temporarily storing the incoming waste water to distribute it to the next stages, a first section for filtering the waste water of the distribution section by m...

A biological treatment system and method is provided for treating wastewater from a treatment plant which provides primary and secondary treatment. An aggregate-filled bed enclosed by a water-impervious barrier is used to receive and cleanse the wastewater using the roots of turf grass grown on the top of the bed. Wastewater is introduced near the bottom of the bed and flows generally upwardly through the voids in the media, passing through the root system of the turf grass. Wastewater is withdr...

A biomass management system using sunlight during the daytime for purifying water having impurities. The biomass management system of the present invention is adapted for use in an impoundment holding water which has an inlet for delivering impure water into the impoundment and an outlet for delivering purified water out of the impoundment. A first type of rooted bottom dwelling plant grows on the bottom of the impoundment and removes some of the impurities in the water. A plurality of elongated...

An integrated system and method for removing excess nutrients from water, for removing the nutrients from the removal site, for enhancing soil, and for producing pulp and paper products includes bioremediating water to be treated with cultured algae or another suitable plant matter in an attached periphyton bed, harvesting the algae/plant matter to produce a wet algal biomass, and mixing the wet biomass with a shredded fibrous material to produce a pulp. The pulp can be molded into a biodegradab...
