BATCH FILTER PRESSES Exotron Batch Filter Presses are used for dewatering wastewater with solids. Different from other presses, Batch Filter... Read more →
The thermal breakdown of materials in the EX Reactor results in the formation of “gaseous byproducts”, or what is more commonly referred to as “pyro gas”. The pyro gas consists of a number of breakdown components and generally has a calorific value. The controlled feed of the solid materials into the first stage results in a constant flow of pyro gasses into the thermal oxidizer, and the subsequent destruction of the pyro gas.
The EX IFTO consists of a multi stage chamber used to drive the primary conversion of the pyro gas to carbon dioxide and water vapor. The typical operating temperature range for the IFTO is expected to be between 1,500°F (815°C) to 1,800°F (980°C).
Higher temperatures can be achieved should it be required for difficult compounds. The system used in this design was built using ceramic fiber insulation on the inside. This is a rather light weight material, and has a relatively long life, whereas the old refractory would tend to fail over a period of years by attrition of expansion and contraction. The IFTO is the first line of pollution control.
Wastewater quality by anthropogenic influence. Wastewater can originate from a combination of domestic, industrial, commercial or agricultural activities, surface runoff or storm water, and from sewer inflow or infiltration.
All waterways are struned with bacteria and nutrients, when waste toxins enter into the waterways it will create a biochemical reactions. The reaction is a biochemical creation ,named by th laboratory that is measuring the reaction as the biochemical oxygen demand (BOD).BODs can be contained by using forceful oxidizing agents and these position of the chemicals create what called a, chemical oxygen demand (COD). Both the BOD and COD tests are a measure of the common oxygen-depletion effect of a waste contaminant. Both have a measure of pollution effect on the environment . The BOD test measures the oxygen demand of biodegradable pollutants and the COD test measures the oxygen demand of oxidizable pollutants.
Chitosan can be used in Waste water processing as a part of a the filtration process. Chitosan causes the fine sediment particles to bind them together, and is removed with the sediment during sand filtration. It also removes phosphorus, heavy minerals, and oils from the water. Chitosan is an important additive in the filtration process. Sand filtration apparently can remove up to 50% of the turbidity alone, while the chitosan with sand filtration removes up to 99% turbidity.
Chitosan is also useful in other filtration situations, when removing suspended particles from a liquid is a necessity. In combination with Benoite, gelatin, silica gel, isinglass, or other fining agents, it is used to clarify wine, mead, and beer. Adding chitosan as part of the brewing process it improves flocculation, and removes yeast cells, fruit particles, and other detritus that cause hazy wine. Chitosan added with colloidal silica has become a superior fining agent for white wines, because chitosan does not require acidic tannins.
Carbon filtering is a method of removing contaminants and impurities using chemical Absorption this is done my using a bed of activated Carbon.
Each granule of carbon provides a large surface area, allowing the impurities the largest possible exposure to the awaken the spores within the filter media. One pound of activated carbon equates to a surface area of approximately 100 acres.
The Activated carbon, a process is called adsorption, when the impure cells are in th liquid at a point to be treated are contained inside the cell configuration of the carbon substrate. Carbon filtering is used for water purification, in air purifiers and industrial gas processing, for example the removal of silicones and hydrogen sulfide from biogas. Respirator masks, also use Carbon to filter out impurities.
Removing chlorine, sediment, volatile organic compounds (VOCs), taste and odor from water, is done with active charcoal carbon filters. They are not effective at removing minerals, salts, and dissolved inorganic compounds.
