Basics of Wastewater Treatment for the Home

The home water treatment system is a step forward form the older septic tank system for waste water treatment. It will provide a cleaner environment.

Home systems and small commercial systems are designed to handle waste treatment in areas that cannot be serviced by city sewer systems. Without a home treatment system, many homes could not be built in areas with very slow percolating soils, clay, rock or high water tables. Some of these conditions can allow effluent from a septic tank to move through the soil without treatment, polluting underground water supplies, ditches and streams. Home treatment systems can remedy those situations by using the same treatment process used by large central treatment plants. They are simply treatment plans down-sized to accomodate smaller requirements.

Piller Blowers in Sulfuric Acid Production

PILLER‘s unique blowers combine high efficiency with high performance. The consistent design starting from the casing over the impeller and shaft seal system to the patented bearings makes possible to use PILLER blowers in almost any applications where high pressure, high temperature or a combination of both is needed. Also corrosive products in the gas stream, combined with water are challenges that PILLER blowers are able to deal with.

As a byproduct of metal ore mining like FeS2, Cu2S or CuFeS2 the sulfur is separated and extracted. Sulfur dioxide SO2 is made by roasting the sulfide ores and oxygen (in the form of air) which combine to form sulfur trioxide in the presence of a catalyst. The PILLER blower provides the oxygen (air) for the process.
