Machinery for Waste Water Treatment
Within the treatment the objective is to retain between 40 to 60% of solid particles, sticks, sands, among others, floating or suspended, that can obstruct the conduits of the system. The following equipment is generally used in a mechanical process.
Coarse Screens and Grating Frames: Ranging from 6 to plus 36 mm, prevent large objects such as logs, boards and other heavy objects from being lifted by the pumps to the other conveyance structures and entering the flow channels.
- Fine Screens
The screens have spaces smaller than 6 mm, retaining solids up to 0.02 mm, widely proven technology as part of a filtration system, has a high efficiency of solids separation. The screens are used according to each case.
- Gravity Separation Systems
Gravity separation systems are designed to remove heavy settleable solids and floating particles in water without the addition of chemicals and energy.
Static and automatic designs, separating grease and organic solids by simple action of its density, different types of sands are used depending on the case, retaining particles thanks to the porosity of the filtering material.
- Primary Sedimentation Tanks (Clarifiers)
They receive the raw water before proceeding with a biological treatment, separating the liquid phase from the remaining solid phase. They vary in shape and size, depending on the type and quantity of water to be decanted.
Called biological, in this stage bacteria are used to consume the pollutants that were not removed in the primary stage. It is also part of the process to incorporate oxygen to the water to promote bacterial growth. The most commonly used systems are: Sistema de precolación
The precollating systems use different types of biological filters with a series of filter beds through which the wastewater to be treated passes, introduced by a network of drippers slowly descending through the filter bed, being circular tanks with different depths.
Dispersed Aeration: The function of this equipment is to introduce large quantities of air at low pressure into the wastewater by forcing it through perforated mesh structures submerged in the water, the movement of the air creates a circulation that evenly distributes the wastewater.
- Regenerative Turbine:
Ideal for small plants with low flow, compact equipment with reduced dimensions. The air inlet is through a receiving flange inside the pump by means of rotor vanes, which rotates connected to the shaft of the electric motor, being possible to obtain vacuum values similar to the multi-stage centrifugal machines.
Esparcidor: Este es un sistema similar pero los chorros de aire de alta presión en un depósito circular al fondo del tanque inician el movimiento del agua que dispersa el aire.
- Anaerobic Treatment
Anaerobic wastewater treatment is used for different sectors of industry as well as to treat wastewater from municipalities. Its use constitutes low energy consumption, sludge production and operating costs, making it one of the most sustainable alternatives for wastewater treatment.
If there is evidence of high concentrations of organic material measured as BOD, COD or TSS, an anaerobic treatment prior to aerobic treatment is recommended.
The purpose of tertiary treatment is to eliminate the residual organic load and pollutants for wastewater discharge, thus avoiding eutrophication or generalized growth of algae in lakes, lagoons or bodies of water with low circulation, as this triggers the consumption of dissolved oxygen and consequently negative impacts on the life of the recipient. Discharges must be within the permissible limits for each region.
Ultrafiltration and Microfiltration: The principle of ultra and microfiltration is the physical separation by the pore size of the membrane. The extent to which dissolved solids, turbidity and microorganisms are removed is determined.
Microfiltration: The pore size of these membranes usually ranges from 0.1 and 10 μm.
Ultrafiltration: The size of retention molecules is between 0.001 and 0.1 μm.
- Reverse Osmosis
Using this technique, it allows the elimination of salinity from water. Physical-chemical treatment. It consists in applying to the concentrated solution a pressure higher than the osmotic pressure, causing the solvent (water) to pass from the more concentrated solution to the more diluted one until a new equilibrium is reached.
It is the final stage before distributing the treated wastewater to the environment. The objective of disinfection is to obtain water continuously free of bacteria and pathogenic germs, in accordance with environmental regulations, since they can cause a health hazard. Disinfection systems are adjusted to the type of water to be treated.
- By Chlorination System: the objective of treating water by dosing sodium hypochlorite proportional to the water to be treated for reuse. It is the simplest and most economical system for tertiary treatment of water reuse for irrigation.
- Ultraviolet radiation (ultraviolet light): For this type of disinfection, UV equipment is used, which provides immediate and more effective disinfection than chlorination and does not require contact tanks, since disinfection is performed instantaneously by the passage of water through the ultraviolet treatment equipment, which favors this type of tertiary treatment when there is not enough space for treatment with chlorine or ozone.
- Ozone is an effective oxidant and disinfectant; it eliminates the source of unpleasant odors and has a higher sterilization speed than conventional chlorine treatment. The time for ozonation is reduced to 3 minutes. In addition, as irrigation water, it provides oxygenation to plant roots.
In Salper Technology we have a wide variety of adsorbent materials and specialized filter media to solve water problems. Applied from elimination of different contaminants present in water such as hardness, odor, color, taste, sediment retention, among others. They are available:
Resin: Resin anion interchange, it uses for water softens whose function is to selectively eliminate dissolved salts
Granulates salt for regeneration: The purpose of this salt is to guarantee the correct functioning of the softeners for the regeneration of resins.
Granulated Activated Carbon: Activated carbon used to remove impurities such as organic matter and contaminants that cause odors, through an absorption process.
Silica Gravel: Used as a support for filter media, the part that is concave in the tanks doesn’t interfere with filtration and here it can be filled with silica gravel. We have different sizes, such as fine, medium and thick. According to the functions to be employed
Zeolite: Granular material with an extremely high surface area, it produces the filtration of solids at an exceptional level, trapping solid particles between the grains, in addition to performing softening functions and eliminating chlorine and iron present in the water.
