COVID-19 - CLARIFICATION - We wish to inform our clients that despite the restrictions derived from the pandemic, Condorchem Envitech maintains its ability to develop projects and install equipment in any country in the world. The start-up of the plants can be done remotely, since they have systems that allow remote management, remote diagnosis and they include an alarm center.
Crystallization is a separation method in which the formation of a solid (crystal or precipitate) is produced from a homogeneous, liquid or gaseous phase. The solid formed can be very pure, so crystallization is also used industrially as a purification process.
The solution must be supersaturated before crystallization can occur. The Crystallization processes differ from one another in the method by which supersaturation is achieved. In general, it can be achieved in three different ways:
The Crystallization process is not simple and the most important step is the formation of solid crystals in the liquid solution. The solution is concentrated and cooled until the concentration of the solute is higher than its solubility at that temperature, and the solute forms almost pure crystals.
Condorchem Envitech, as a crystallizer manufacturer, has extensive experience in the design, manufacture and installation of wastewater crystallizers. Each crystallizer plant has its own peculiarities, which vary for different types of industry.
At Condorchem Envitech we are specialists in vacuum crystallizers for the treatment of high pollutant effluent and the concentration of raw materials.
Our DESALT® equipment provides a very high percentage of clean water to be discharged or reused, and a minimum solid concentrate to be sent for disposal or used as raw material to be recovered or as a by-product.
Crystallization is a good option if you are committed to zero discharge. This technology is particularly suitable for high salinity effluents (brines).
Condorchem Envitech’s range of crystallizers for wastewater treatment includes the following industrial crystallizer equipment
:This industrial vacuum crystallizer is used for applications in which simultaneous concentration and drying in the same equipment is required: Crystallization of brines, concentration of spent working baths and concentration of extracts and fragrances.
The product can be extracted manually or with the help of a spindle (optional).
It is a vacuum evaporator-crystallizer: electric, low temperature and of horizontal construction. This evaporative crystallizer design is operated by an electric heat pump, has a very compact structure and does not produce emissions or odors. It can be built in highly corrosion resistant materials if required.
It is designed to obtain solid, crystalline, paste or gelatine concentrates, as well as to recover raw materials present in wastewater.
Its capacity range is 250-1,000 L/day.
This industrial crystallizer is used for applications to treat fouling liquids, brines, glues, inks and paints, for example.
It is a vacuum
evaporator crystallizer system, of vertical construction with an internal scraper with blades. The heating is via steam or hot water. It can be manufactured in highly corrosion resistant materials if required.This wastewater crystallizer is designed for the concentration or Crystallization of brines and concentrated fluids from an
evaporator crystallizer. Organic fluids can be concentrated into paste form. The equipment is especially recommended for treating fouling wastewater and high density aqueous solutions.Its capacity range is 500-3,000 L/day.
The operation of a crystallizer is very similar to that of a vacuum evaporator, except that it is designed to evaporate all the solvent and leave a very concentrated, pasty, gelatinous or crystalline product. There is usually a side opening so that it is easy to open and accessible for the manual extraction of the crystallized salts. At the end of the working cycle, the vacuum is released and the boiler contents are manually discharged with a scraper blade via one of the front doors.
Crystallizers can work well with a heat pump, steam or hot water.
