Dosing pumps
In water treatment, the Dosing Pump allows you to volumetric accuracy or time any chemical to water.
The Dosing Pump ensures constant application of the desired chemical, resulting in more efficient treatment of water, with no chemical waste.
Thus ensures economically that water has the required chemical conditions.
filters
In water treatment, filtration sediment is calculated on the basis of existing in water cloud taking account of the characteristics desired and what type of application.
The Housing that suppors the cartridge is designd for a specific flow rate and a given water speed.
The type of material that make up the raw material identifies its use in food quality, and industrial taking into account, the temperature, and chemical composition of the fluid to be filtered.
Filter elements
In water treatment, the degree of filtration is normally measured in microns the efficiency obtained in each filter element.
The degree of filtration depends on the matter that the filter element comprise more or less efficiently depending on the type of filtration, depth, characteristics, area and the type of filter material.
Ultra filtration
In water treatment, The ultrafiltration process is a mechanical process without chemical alteration of the filtration water physico.
In this type of equipment the standard multimidia pre treatment is very important. For correct calculation of a UF system the complete chemical analysis is indispensable.
In some situations the UF alone will not be the only solution for the removal of suspended solids, taking into account capacity vs quality and durability.
The process is relatively simple and getting a distinguishing quality when we apply the system as finalizing or pre osmosis treatment, effective in some cases in the microbiological control.
Iron Removal
In water treatment, The catalytic process of removing iron and manganese from water by precipitation causing deposits and cause the emergence of bacteria, stains and odors.
The process is carried out using a medium to cause a reaction between oxygen present in the water and contaminants.
This reaction forms a precipitate that can be filtered by the filter medium.
The amount of filter medium is calculated according to the iron values present in the daily water consumption of the plant.
To remove the iron deposits staying on the filter medium is necessary to make a countercurrent washing.
The automatic control valve throughout the complete washing cycle. washes intervals are defined by the installer.
Arsenic Removal
In water treatment, the Arsenic is an element that may be present in various types of rocks and soils. As such, through contact between the water and the rock or soil, it can dissolve in water and be present in high concentrations.
Removal of arsenic in drinking water is essential, since according to the WHO, these values should be below 0.01 mg / l.
The equipment is designed for the removal of arsenic by adsorption with highly selective metal oxides.
These devices are effective concentrations of up to 100 ppb reducing arsenic to below 10 ppb. Useful for reduction by adsorption or co precipitation.
The pH of the water should be between 6 e 7.
multimedia filter
In water treatment, industrial filtration process is the removal of suspended matter in water. This process consists in passing the water through the media that are within a polyester bottle.
The filter material is Flint, or zeolite of different particle sizes, e hidroantracite.
The filter beds and retain the particles when they are saturated, It is necessary to wash (backwash) to return to have the same holding power.
The entire process is controlled manually or automatically by a valve installed at the top of the bottle.
Chlorine removal
In water treatment, active carbon is used for adsorption of odor, color and flavor adsorption, as well as the elimination of chlorine and synthetic or organic contaminants present in the water.
The dechlorinators are calculated for the elimination of chlorine with a contact time of 4 minutes.
For other applications it is necessary to perform the calculations depending on the concentration of the contaminant to remove (DQO, organic compounds, Hydrocarbons,etc.).
It is advisable to perform a daily washing in order to remove the suspended solids, prevent and eliminate bacterial growth preferential channels.
Activated charcoal, made from coconut shell, with a high percentage of micropores with diameter most appropriate for the removal of small molecules.
Very suitable for the removal of contaminants in the water give excellent results in dechlorination and retaining organic contaminants, as pesticides, phenols, detergents, dissolved fats and carcinogenic compounds.
chemical dosing
In water treatment, the chemical assay consists of adding chemicals in water, through metering pumps, in order to change its chemical composition.
The product to be dosed varies depending on the need to install and may be a disinfectant for removing bacteria, pH regulator, product against fouling etc ...
The amount of product to dose also varies according to the needs of the facility and should be consulted the respective sheet to be planning to make a correct dosing.
Softening
In water treatment, the limestone problem is a very common problem in water mainly in the central and southern regions of Portugal. limestone deposits can cause blockages in plumbing and malfunctions in machinery.
The equipment is softener to remove calcium and magnesium ion exchange via. The water passes through a cation resin bed which retains the calcium and magnesium ions and releases sodium ions.
After a certain volume of water is saturated resin, and it is necessary to make a regeneration of the resins to be reset to exchange capacity.
Regeneration is programmed by a controller and can be volumetric (regeneration is done after passing a certain flow rate of water) ou cHRONOMETRIC (They are programmed day to regenerate).
In the regeneration step, the resins are washed with brine, so that all equipment is complemented with a tank which is placed water and salt to make brine,. For each lt. resin are required 0,2 Kg of salt to regenerate.
Desnitrificação
In water treatment, the nitrate reduction by selective ion exchange resin. Regeneration with brine. volume regeneration control.
strongly basic ion exchange resin, macroporous structure and polystyrene skeleton, intended to removal of nitrates from drinking water.
The strong anionic resin, generally, It has more affinity to retain water sulphates.
On the other hand, The resin for nitrates has the characteristic of being more selective than the front nitrates sulfates although the concentration is higher than the latter.
Under current law, the maximum allowable concentration of nitrates in water is drinkable 50 mg / L NO3-. A leak nitrates will be approximately 13% Initial concentration.
To adapt the desnitrificador the treated water is required for the calculation: concentration of nitrates, sulfates, peak flow rate and consumption. 1Lt. of consumed resin 0,25 Kg of salt in each regeneration.
reverse Osmosis
In water treatment, Osmosis is a natural and physical process, which is based on applying a pressure on the concentrated water, to force passing of this through a semipermeable membrane, allowing the passage of water but not of the salts and other organic compounds, microorganisms and suspended solids.
Thus, we got hold, the membrane, most of these substances, thus obtaining a higher quality water with a much lower initial salt concentration at.
A reverse osmosis equipment comprises:
• Pre sediment filter for removing particles
• pre carbon filter for removal of chlorine existing in the water
• Osmosis Membrane – semipermeable retention for salts, microorganisms and particulates
• Post carbon filter – final treatment to remove any leftover flavors in the water after Osmosis
ROSW (Referse Osmosis Sea Water)
In water treatment, the removal process by osmosis sea water salts.
The process relies on the pressure of the water so that it crosses a semipermeable membrane specially designed for sea water, which allows the passage of water, but retains salts.
The pressure that is exerted has to be greater than 30 atm so that give the osmosis process.
Chlorine dioxide
In water treatment, equipment to produce chlorine gas. Chlorine dioxide is a strong oxidant and a strong biocidal. It has the advantage over other oxidants such as ozone or chlorine because it is less reactive.
Working in a range of pH too high (between pH4 and pH10), destroys more effectively: spores, bacteria, viruses and other pathogens.
Requires less contact time, when compared to other oxidizing, It has better soludibilidade, and even at high concentrations of chlorine dioxide is not corrosive to materials.
Chlorine generators are used to produce gas locally, because of the difficulties that presents both storage and handling.
It can be applied in hot and cold water systems, washing vegetables, prevention and control of biofilms, prevention and control of legionella, cooling towers, potable water, etc.
