Abstract

The invention relates to a composition and method for the treatment of wastewater and sewage water in order to produce drinking water in accordance with drinking water purification standards. The inventive formula is based on completely natural elements, mainly calcium, but can also be based on synthetic elements. The method is novel in that it can be used to purify wastewater or sewage water, i.e. water contaminated with chemical substances, algae, micro-organisms and suspended particles, until said water is drinkable and suitable for human and animal use. In addition, the sludge and sediment obtained during said wastewater and sewage water treatment method is completely inert and free of contamination and, as a result, can be used as a nutrient material or compost in cultivation, sowing or aquaculture, rendering same suitable for use in various different areas of application.

Description

COMPOSITION AND PROCESS FOR TREATMENT OF RESIDUAL AND BLACK WATER OBTAINING DRINKING WATER.

BACKGROUND

Currently, various types of wastewater treatments based on solid flotation, crushing of solids, chlorination to deconcentrate suspended solids, filtration and purification, which use iodide and a range of acids, such as muriatic, sulfuric and mixtures are known of synthetic chemicals, oxygen-based process and anaerobic process, methods and processes described in FR 2,036,685, FR 2,226,361, FR 2,534,897, European Patent Applications 9591393.02., 89400156.9., 94916718.9 and E95913932. All the aforementioned processes and known worldwide, are treatments that result in the obtaining of hard and heavy waters, they are second-class waters, which are destined exclusively to the irrigation of gaps and roads. In addition to this, the great problem of sludge or sediment that results from wastewater treatments, which are highly polluting and must be treated separately for their destruction.

FIELD OF THE INVENTION

The present invention relates to a formula or composition and process for the treatment of wastewater and sewage, water contaminated with chemicals, microorganisms, suspended particles and heavy metals; This composition and process can be applied in tanks or in the natural channels of rivers or lakes. The proposed formula is a completely novel composition based mainly on calcium, and unlike other formulas for treating wastewater and sewage, with this the transformation of sewage or wastewater into drinking water is achieved. The drinking water that is obtained complies with the

Water purification for use in animals and humans. More specifically, wastewater or sewage (sewage) containing contaminants can be effectively treated by applying the formula or composition and procedure proposed.

Natural components of the formula (composition):

AL (Aluminum) 0.0043 mg / kg

Ba (Barium) 0.0057 mg / kg

B (Boron) 0.0020 mg / kg Cr (Chrome) 0.005 mg / kg

Cd (Cadmium) O,0001 mg / kg

Ca (Calcium) 43.9372 mg / kg

Cu (Copper) 0.007 mg / kg

P (Phosphorus) 0.3579 mg / kg Fe (Iron) 0.1687 mg / kg

Mg (Magnesium) 0.4591 mg / kg

Ni (Nickel) 0.005 mg / kg

Pb (Lead) 0.0030 mg / kg

K (Potassium) 0.0958 mg / kg Na (Sodium) 0.0543 mg / kg

Yes (Silicon) 0.0972 mg / kg

Zn (Zinc) 0.0062 mg / kg

The procedure that is being proposed is presented in the following description and in the figure described below:

Figure 1: Flow chart of the procedure consisting of six stages or steps for the treatment of wastewater or sewage to obtain potable water.

Stages of Agitation and Incorporation of the elements of the Formula.

In real time and respecting the order of the elements contained in the previous formula, they are incorporated one by one with an interval of 10 minutes of separation in the wastewater or black water to be treated with a concentration of suspended solids of 452 per cubic millimeter, which must previously be in a state of agitation for up to three hours for every 50 cubic meter produced by blades, propels, or any another form of mechanical movement, with a movement or swell speed of 350 kilograms of impact pressure in the area per 1 cm2 centimeter (one square centimeter).

Heating-Boiling Stage.

The boiling movement due to temperature changes of 10 to 99 degrees Celsius is obtained by the heating that results from contacting the components of the formula with the wastewater or sewage to be treated, and is complemented by heat application by different methods of heating, such as direct flame or solar cells, the boiling impact movement is 250 grams in a test area of Icm2 (one square centimeter).

Resting stage and deconcentration of solids.

The aqueous mixture is left in a rest period of 3 hours, during this time there is a deconcentration reaction of suspended solids with parameters of 150 to 800 per cubic milligram, obtaining a cleaning by deconcentration of suspended solids of a 80% per cubic milligram.

Suspended solids descend to the bottom of the tank or riverbed, being a completely inert mud.

Filtration and oxygenation stages. The process that is being presented also consists of a filtration stage and an oxygenation stage, which is important to mention because it is part of the process for obtaining drinking water, but any of the known filtration and oxygenation processes within the state can be used of the technique for the treatment of wastewater and therefore are not a matter of complaint.

The sludges that are obtained or that result from the described technique (formula and process) are completely inert residues, free of any bacteria or larvae, which have excellent sedimentation characteristics and with natural properties to be used as fertilizers in farmland, applied in aquaculture or 'as a biological activator for lakes, ponds and the like, without risk of contamination. Unlike sludge that results from other wastewater treatments, where it is necessary to give a specific treatment to such sludges as the one mentioned in European patent application No. 99946262.5, in our process it is not necessary to give the sludge any special treatment For its destruction, it is more as already mentioned above, this mud is usable as a nutrient in various areas.

An example that illustrates the procedure, including the best mode, is transcribed below. This should not be construed as limiting but only as an illustration of the procedure.

Example 1.

Treated water of the Lerma river.

30 liters of contaminated water were taken from the Lerma River, the temperature resulting from 21 degrees was taken, the pH resulting from 12.5 was measured and the specific weight of the solids was 1,150 solids per cubic centimeter, water was stirred With a mechanical traction movement, while the water continues to stir, the elements of the formula that we are protecting are incorporated one by one, with a separation interval of 10 minutes between them, then the temperature was taken and resulted in 90 degrees Celsius therefore, heat was applied through direct flame, the temperature was taken again and heat was applied until it reached 99 degrees Celsius. The mixture was left at rest, and in the first 30 minutes the initial deconcentration of the solids began to be seen, a sample was taken and placed in a flask with a scale of one to ten of the volume of a liter, there was observed solids deconcentration, if the reaction was effective, the solids move to the bottom of the tank, and clean water free of solids is obtained after three hours. Subsequently, the Filtration and Oxygenation stages are carried out to obtain drinking water according to the drinking water rules.
