Definitions
- the present invention describes a compact real-time wastewater treatment system. More specifically, it comprises a system that enables the treatment of industrial, domestic or mixed effluents with practically zero effluent residence time and without the production of odors or residual sludge.
- Sewage, effluent, or wastewater is all liquid waste from industry and households that needs proper treatment to remove impurities and thus be returned to nature without causing environmental damage and human health.
- Effluent treatment systems are based on the transformation of dissolved and suspended pollutants into inert gases or sedimentable solids for further separation of the solid / liquid phases.
- the prior art describes various wastewater treatment systems that basically follow a set of steps that include pretreatment, primary treatment, secondary treatment and tertiary treatment.
- the pre-treatment stage consists solely of physical processes, and removal of suspended materials and coarse solids is foreseen.
- the primary treatment step is foreseen which includes physicochemical processes for the equalization and neutralization of the effluent charge, with the separation of liquid or solid particles through flocculation and sedimentation processes.
- organic matter and nutrients such as nitrogen and phosphorus are removed by biochemical reactions by aerobic or anaerobic processes.
- the tertiary treatment or "polishing" step may be employed for the purpose of removing specific pollutants (usually toxic or non-biodegradable compounds) in wastewater prior to discharge into the receiving body and / or for closed system recirculation. or for the further removal of pollutants not sufficiently removed in the secondary treatment.
- specific pollutants usually toxic or non-biodegradable compounds
- tertiary treatment methods correspond to advanced effluent treatment using techniques with such high power to remove sewage forming agents that even make water reuse possible.
- Tertiary treatment foresees treatment methods for sewage disinfection, that is, it removes pathogenic organisms from the sewage and treatment methods for the removal of nutrients, which aims to avoid imbalance in the disposal of elements. in the recipient body, preventing eutrophication, a phenomenon of overgrowth of aquatic plants and organisms such as algae, which have the potential to release large amounts of toxins, causing fish to die, affecting biodiversity, releasing toxic odor-causing gases. unpleasant and decreasing water transparency.
- the object of the present invention is a compact real-time effluent treatment system which enables the treatment of industrial, domestic or mixed effluents with virtually zero effluent residence time and without the production of odors, gases or residual sludge. demanding an area for installation of the treatment plant about ten times smaller than the conventional ones, fully complying with all the phases of the effluent treatment prescribed by the environmental legislation.
- a compact treatment system is characteristic of the invention. real-time effluent treatment that enables the treatment of industrial, domestic or mixed effluents with effluent residence time in the system practically null and without the production of treatment and post-treatment odors, gases and residual sludge.
- the invention features a compact real-time effluent treatment system that promotes the treatment and disinfection of sanitary or industrial effluent, giving it Class II water characteristics, according to CONAMA Resolution 357 of December 2006.
- the invention features a compact real-time wastewater treatment system that fully complies with all stages of wastewater treatment prescribed by environmental legislation by disinfecting treated wastewater for the removal of pathogenic organisms or, in special cases, removal of certain nutrients, such as nitrogen and phosphorus, which may enhance, either alone or in combination, the eutrophication of recipient waters.
- a compact real-time wastewater treatment system does not require an additional disinfection system.
- a compact real-time effluent treatment system can be adapted for the abstraction and treatment of water for human consumption.
- Figure 1 shows the schematic representation of the compact effluent treatment system.
- Figure 2 presents the representation of peripheral equipment.
- FIG. 3 shows the flowchart of the wastewater treatment process steps using the compact wastewater treatment system.
- the compact real-time wastewater treatment system which is the object of the present invention, comprises a set of associated units in a closed loop that fully comply with all stages of wastewater treatment prescribed by environmental legislation, from pre-treatment to tertiary treatment. so that the released fluid is fit for reuse.
- the compact real-time wastewater treatment system comprises a physical attack module that includes a collection unit (10) interconnected to the collection network (100), said collection unit (10) which has a raw effluent inlet valve to arranging a coarse particle retention means (not shown) that prevents ingress of material that may cause damage to the equipment.
- the raw effluent is pumped through a first motor unit (20) through ducts to a homogenization unit (30) where the floating material present in the liquid effluent is withdrawn to avoid damage to the
- a homogenization unit (30) where the floating material present in the liquid effluent is withdrawn to avoid damage to the
- the effluent released from the homogenization unit (30) goes to a physicochemical attack module by acting a second motor unit (21), said effluent that goes through an oxidative process where an ozone generator (40) performs the ozonation of the effluent to break down the carbon chains of proteins such as cadaverine and putrecin, avoiding the odor of rot; polymers, such as polyphosphates derived from the use of detergents, preventing post-treatment phosphorus pollution; oxidation of organic carbon to carbon dioxide and water, thereby destroying the energy source; oxidation of organic and ammoniacal nitrogen to nitrate, avoiding foul and unpleasant odors; oxidation of sulfur to eulfate, preventing gas formation suifidric and its unpleasant odor; oxidation of the heavy metals present, reducing their toxicity; oxidation of phosphine to phosphate and phosphorous oxide (insoluble), avoiding its high toxicity and unpleasant odor and recovery of dissolved oxygen concentration
- the oxidized effluent is sent to the chlorination unit (50) where it is subjected to the action of sodium hypochlorite (NaOCI) with ingress controlled by a first metering pump (60), said sodium hypochlorite that ensures greater stability. and promotes the elimination of saprophytic bacteria, thermotolerant, total and fecal coliform and other microorganisms by chance present, to ensure a concentration of 10mg Cl 2 / L to the thin! of the sterilization phase.
- NaOCI sodium hypochlorite
- the effluent flows to the fine filtration unit (70) where filter media (not shown) having a particle holding capacity of up to 0.002 microns is arranged.
- This filtering condition is necessary in order to provide a high degree of transparency that does not impair the efficiency of ultraviolet sterilization.
- the effluent is released from the fine filtration unit (70) and proceeds to the sterilization unit (80) where ultraviolet radiation is applied to provide for the elimination of oxidation resistant microorganisms, including viruses that are normally present in sanitary effluents.
- the treated effluent (type II water) proceeds to a release duct (90) to flow into a receiving body.
- the filter media have as their material filtering the pebble, sand, zeolite and charcoal.
- the system features a first metering pump (60) for controlling sodium hypochlorite ingress through a specific duct in the first motor unit (20), and a second metering pump (61) for controlling aluminum sulfate ingress (AI 2). S0 4 ) through a specific duct in the second drive unit (21).
- the ozone generator (40) is powered by an oxygen concentrator (41).
