Abstract: A novel lagoon aeration treatment system is provided which can be used with existing or new wastewater lagoons to increase the lagoon's treatment efficiency and capacity, and to allow for a continuous, year round discharge of treated wastewater to the environment. The system can be operated in warm and cold climates for treatment of municipal and industrial wastewaters of varying strength and flow rates in a secondary activated sludge treatment process, a tertiary activated sludge treatment process, or an extended aeration treatment process.

Abstract: The super oxidation, coagulation and flocculation system is applicable to water and wastewater chemical treatment in which oxidation, coagulation and flocculation processes take place in a single vessel. The apparatus and process can be used for treatment of domestic and industrial water and wastewater for removal of organic and inorganic contaminants. The oxidation process can be provided by several oxidizing chemicals such as ozone, hydrogen peroxide, potassium permanganate, chlorine and Ultra Violet Lights, and the coagulation process can be accomplished with several coagulants such as aluminum sulphide, ferric chloride, ferric sulphate. Selection of the chemicals depends on the quality of the water or wastewater to be treated and the treated water quality required, and it covers a wide range of impurities to be removed and specifically difficult to oxidize hydrocarbons and chlorinated organics, and iron, manganese, uranium, arsenic, cyanide, hydrogen sulphide.

Abstract: A biological wastewater treatment system is provided which is adaptable to small, shop fabricated package plants and large, assembled in place plants, and which can be operated as a secondary treatment, activated sludge process, for suspended solids and BOD removal, or a tertiary treatment, activated sludge process, for suspended solids, BOD, nitrogen and phosphorus removal. The system includes a wastewater pump and an air aspirator-mixer to provide aeration, sludge recirculation and waste, and wastewater recirculation for the secondary and tertiary treatment processes. The aeration system with the air aspirator-mixer transfers oxygen to the wastewater, and is located outside aeration tanks. The wastewater pump and air aspirator-mixer system lends itself to continuous and cyclic aeration and oxic and anoxic treatment processes. The multiple use of the wastewater pump for aeration, recirculation and sludge waste minimizes the number of pumping systems required and eliminates air blowers.

Abstract: A syphon filtration system is a low head, small foot print, long operating cycle, gravity filtration system for treatment of water and wastewater, with one-stage or two-stage filtration in one vessel with different filtration media of sand, anthracite, granular activated carbon or other proprietary filtration media. The one-stage filtration system removes suspended solids or dissolved impurities and the two-stage filtration system removes suspended solids and dissolved impurities. In the two-stage filtration system, each filtration stage can be backwashed independently or both stages can be backwashed simultaneously. Novel syphon piping and controls design extend the filtration operating cycle and reduce the filter apparatus headroom, and the filter backwash water volume requirements.

Abstract: The Water Distribution System is specifically applicable in cold climates in which water distribution systems may be subjected to freezing during the winter months. The Water Distribution System is applicable to domestic, industrial, recreational and institutional water distribution systems including water transmission and distribution mains and service connections. The Water Distribution System has applications in specific terrain and climatic conditions such as high bedrock, high groundwater table and permafrost. The Water Distribution System may, in specific terrain and climatic conditions, use uninsulated or insulated water mains and service connections, but without heat tracing or water bleeding in any case. The Water Distribution System is applicable to single and multiple complex distribution pipe systems arranged as parallel or looped, or combination of both arrangements.

Abstract: A versatile and efficient biological wastewater treatment system is provided which is adaptable to small, shop fabricated package plants and large, assembled in place plants, and which can be operated as a secondary treatment, activated sludge process, for suspended solids and Biochemical Oxygen Demand (BOD) removal, or a tertiary treatment, activated sludge process, for suspended solids, Biological Oxygen Demand (BOD), Nitrogen and Phosphorous removal. The system major equipment includes a wastewater pump and an air aspirator-mixer to provide aeration, sludge recirculation and waste, and wastewater recirculation for the secondary and tertiary treatment processes. The aeration system with the air aspirator-mixer is highly efficient in oxygen transfer to the wastewater, easy to maintain and versatile to use, as it is located outside aeration tanks. The wastewater pump and air aspirator-mixer system lends itself to continuous and cyclic aeration and oxic and anoxic treatment processes.

The filtration system is an apparatus and process with one-stage or two-stage filtration process in one vessel. The filtration system can use different filtration media of sand, anthracite and activated carbon or other proprietary filtration media. The one-stage filtration system is applicable to removal of suspended solids or dissolved impurities. The two-stage filtration system can provide a combination of two different filtration processes for removal of suspended solids and dissolved impurities. The one-stage filtration system has low head room requirements, and the two-stage filtration system has small foot print requirements. In the two-stage filtration system, each filtration stage can be backwashed independently or both stages can be backwashed simultaneously.

Abstract: A novel, economical, efficient and versatile lagoon aeration system is provided which can be used with existing or new wastewater (sewage) lagoons to increase the lagoons treatment efficiency and capacity, and to allow for a continuous, year round discharge of treated wastewater to environment. The system can be operated in warm and cold climates for treatment of municipal and industrial wastewaters of varying strength and flow rates in a secondary activated sludge treatment process or in a tertiary activated sludge treatment process, or an extended aeration treatment process. The system employs patented (Patent No: U.S. Pat. No. 6,969,052 B2) Air Aspirator-Mixer (AAM) which provides highly efficient wastewater aeration outside the lagoon which facilitates an easy and economical operation and maintenance of the system throughout the year.

Abstract: A single port venturi device is provided for aeration of wastewaters containing suspended solids. The device has a non-obstructive design which prevents attachment or accumulation of suspended solids, and promotes even air distribution for efficient aspiration of air and mixing of air and wastewater. The device has provisions for adjustment of the venturi throat size, for protection of the throat from wearing out, for enhancing air and wastewater mixing capabilities, and for flushing of the solids accumulated in the air entrance.
