Dosage

Unlike other pumps, dosing pumps aim to deliver a quantity of a product as precise and accurate as possible to a system. The pumps can be powered by electricity, hydraulics, pneumatics, etc.

Among the electrically powered pumps, there are a variety of these devices such as: piston diaphragm, peristaltic, scre, love, etc.

Of these, the most common are the diaphragm because of its simplicity, low cost and flexibility of applications. For pumps that use electricity diaphragm, two groups differ, depending on their drive: electromagnetic and electromechanical pumps.

Electromagnetic Pumps

(Operated Electrically or Magnetically Energized)

The motor is a coil when energized produces a magnetic field produced by the violent movement of a rod or shaft steel.

The injection flow from this type of pump, varies with respect to the opposing pressure in the discharge like of the metering pump, that is, if the pressure in the injection line goes down, the flow of the pump increases, on the contrary, if the pressure increases the liquid flow that the pump delivers goes lower.

Electromagnetic Pumps

(Energized Electrically, Mechanically Operated or Gear)

Is an electric motor that moves an eccentric turning gear set which at the same time moves an arm in one direction and then in the other.

This will depend on the type of product to be dispensed, meaning, if the product to be injected is too expensive or it requires a very precise injection, an electromagnetic pump will be required. On the contrary, a product is dose, this, may vary in a injection range, a cheaper pump like the electromagnetic would be a good choice.

In order to cover all the needs of our customers, Aguasin offers both technologies.

o What data are required to define a dosing pump?

The following data are required:

• Liquid flow to dose: it is the quantity of chemical product that it is wished to be injected in the system. Normally refers to L/h o cm3/h
• Line pressure which where the injection pump will be installed.
• Temperature of the liquid to be injected with the metering pump.
• Chemical product to dose.
• Viscosity of the chemical product, special parts will be required. It's recommended to know if the main liquid (Water mold or of any liquid or solid) if it is constant or not, in order to adequately select if more than one fluid meter is required.

Flow Controllers

These are technical equipment that allow to meter the water fluid or any other material in industrial processes. In the case that dosing of a chemical product is required, always must define if the main fluid (water mold for example) is constant or variable. This will allow to adequately define if the installation of a fluid control is necessary.

Our line has suitable equipment for different types of processes, specializing in water.

These equipment is set to adjust the maximum regime purges of a boiler. In general, bottom withdrawals of a boiler allow to eliminate the solids that may be formed in the water, product of different chemical phenomenon.

Additionally, it is used to control the salt concentration of the boiler. With time and research it was found that a boiler can save oil energy and the reposition of water when performing a controlled bleed from the top of them dome of water.

An automatic control allows a cost reduction of fuel from a 5 to a 10%. If the salt concentration in a boiler is manually controlled by the bottom bleed when installing a system of surface bleed, automatically controlled, the savings will overcome the previous numbers.

The results of these savings can be verified in the short, average and long term depending on the boiler operation system and in the process that uses its steam.

Our control system allow to measure the water characteristics of the boiler right on its temperature, by using a manifold specially designed for it. This is so as to simulate the internal characteristics of the boiler. In general, the sensors used by our team are used to measure the temperature.

Operational Logistic

The equipment is programmed with great conductivity value or sent-point, when exceeded, causes the controller to order the opening of the motorized valve (this means that opens and closes slowly avoiding the battering ram hits in the manifold). The valve opens for a little while from which then it closes. The controller again reviews the conductivity that the water presents over the sensor.

If necessary, the controller again will order the valve to open. The selected equipment may also be provided with a flow sensor with the aim of measuring the flow of replenishment water. Accordingly, three pumps are operable to dispense chemicals.

These teams are set to adjust the maximum purges regime of a cooling tower, allowing both to maximize the use of water resources, and get the most out of the applied chemical treatment program.

Our control systems allow to measure the water characteristics by using a manifold specially designed for this. This is so as to simulate the internal characteristics of the boiler.

The technologies that we currently manage are by measuring conductive conductivity and inductive conductivity, applying each case in the solution set for each suitable system.

Added to this, the equipment used also allow us to measure both makeup water flow as the water flow discharged by purging, this allows to establish directly the concentration cycles, to which our system operates. In addition, it allows us to assess the impact that the purge flow will have in the evacuation of liquid industrial waste or LIW.

The selected equipment may also be provided with one or two flow sensor with the aim of measuring the flow of replenishment water. Accordingly, three pumps are operable to dispense chemicals. In both cases, totalized water values will be available in order to a system response and for the eliminated water as purge.

These equipments allow to adjust the acidity which presents a liquid, whether it will be liquid or a liquid residue process. Similarly, the equipment considered for this purpose go from simple solutions such as the use of metering pumps with Ph sensor incorporated to more sophisticated control systems. The application of one or the other method, it will be given by the suggested solutions particularly to each of our clients.

In the case of metering pump, the controller is integrated in the pump itself, which is programmed with a set-point ph to control the operation from the same. Thus, the pump dispenses the product acid or the alkaline product, allowing to adjust the pH.

If the water flow is available it can be also extremely acidic and basic or alkaline, two dosing pumps should be available, each one with their respective pH sensor.

If a tower is required to control the pH of a cooling tower, there will be a team that can measure pH and simultaneously control two or three metering pumps, plus a purge valve.

One of the most effective methods for the removal of pathogenic microorganisms, both humans or other species, is chlorine dioxide. It's more stable than ozone and more reactive than chlorine, is the ideal product for sanitizing drinking water, process and waste.

Due to the action of chlorine dioxide, besides oxidizing the cellular wall of viruses, it is permeable through the wall and it destroys its genetic code, completely disabling the entire structure.

Chlorine dioxide which in our weather conditions it is an unstable and very reactive gas, yellow, with an intense "chlorine" smell, and it must be generated in-situ, under the adequate pressure and temperature conditions.

The equipment for the chlorine dioxide generation that we now have fulfills the highest quality and safety standards of the European Economic Community.

Using as a raw material, the products of Dioxid A and Dioxid B, can generate up to 450 g/h of chlorine dioxide in aqueous solution.

The chemical reaction that gives rise to chlorine dioxide is as follows:

4 HCl + 5 NaClO2 -----> 4 ClO2 + 5 NaCl + 2 H2O

The main characteristics of chlorine dioxide prepared in-situ are:

• Low cost of operation and maintenance.
• Full traceability of the process
• pH independence.
• Availability of the product without degradation.

Among the most known chlorine dioxide applications are:

• Disinfection of drinking water.
• Water Disinfection process.
• Virus Removal (very complex today).
• In the oxidation of iron and manganese.
• Natural water color removal.
• pH independency.
