Evaporation suitable for pharmaceutical manufacture.
Evaporation suitable for pharmaceutical manufacture.
Water from Astra Zeneca’s factory in Mölndal, Sweden, is purified using the evaporation technique.
Evaporation is a method of concentrating a solution or suspension by vaporization. By conveying heat to a weakly concentrated liquid solution the solvent, usually water, is induced to boil whereby the concentration of the required substance increases in the remaining fluid. Evaporation can be carried out in several steps and at varying pressure. It is a usual process in the food, engineering and paper industries. Since the active substances in pharmaceutical manufacturing are salts it is an eminently suitable method because the salts can be vaporized at the same temperature as water.
Co-operation between Vilokan and SKF
SKF builds a factory in Russia using purification technique from Vilokan
The SKF Group is the world-leading supplier of products, customized solutions and services within the sector covering rolling bearings, tightening material, mechatronics, service and lubrication systems. SKF’s service offer contains services such as technical support, maintenance service, condition monitoring and education. SKF’s activities are organized according to customer segment and divided into three divisions: The Industrial Division and The Service Division, which serve industrial OEM-customers and the industrial aftermarket, and the Automotive Division, which serves OEM and aftermarket customers within the automotive industry. The number of customers totals some 2 million. When the decision was made to build a new, environmentalfriendly factory in Tver, 150 km south of Moscow, Vilokan was chosen as the supplier. Vilokan will supply two systems, one for the surface treatment which is a zinc phosphatising. The plant will be without wastewater, with automatic purification of the zinc phosphatising stage and purification of incoming water. All oily water from other production will be purified and re-cycled. The whole contract, including control and electric wiring, will be supplied by Vilokan. The evaporation system is one of the latest types with low energy consumption and complete separation, which means that the highest possible degree of separation of the organic content in the purified water is automated in the actual evaporation process.
A partnership with advantages.
Vilokan’s investment in service has been well received by our customers.
Our new Vilokan Service Partner Contract has been signed by more customers than anticipated. It is a well-known fact that preventive measures afford better control and operating reliability, which in turn increases safety. But when the plant is also documented, even acute problems can be foreseen and remedied in a better way. By becoming a Vilokan Service Partner your company can safeguard a successful principle for water purification and keep the company’s quality and environmental work up to date.
Vilokan develops:
New technique for purification of zinc phosphate baths is introduced.
It is a well known fact within the surface treatment industry that keeping active zinc phosphate free from sludge is a complicated and timeconsuming work. In order to facilitate this Vilokan has worked for a number of years with different methods. The latest in a row of solutions is an automatic high-pressure band filter. The first installation was made in the autumn 2009 and we are very much looking forward to receiving the feed-back from the installation which also contains iron reduction.
New member of the team.
Vilokan’s service team strengthened.
As a lead in our efforts to increase availability and service to our customers we are now pleased to welcome an additional service technician, Bert-Ove Hellgren “BEO”, to Vilokan. BEO has long and sound experience of both cooling and ventilation installations. He comes from Luftteknik, where he has been employed as a service technician. Proximity is important and as BEO is now in Lidköping we will be able to offer even better service to our customers in that area.

Liquid is purified by centrifugal force.
The technique is used to separate chips and other particles by centrifugal force. The cyclone is used within the engineering industry for separating particles in air and liquids. Vilokan works only with the liquid part.
It works like this:
The liquid is pumped into a horizontal inlet where it forms a primary vortex, which increases in velocity the lower down it comes in the cone. The velocity is highest at the bottom of the cone. The vortex turns and forms a secondary vortex, which rises up to the centre through the primary vortex. When the vortex turns the particles are thrown out by the centrifugal force and are separated. The particles are then led out through the end of the cone together with a small amount of liquid.
Delivery to China.
Closed system affords full control.
NUCO, who manufactures lamp reflectors, has now been supplied with a surface treatment system without wastewater. The company is located near Shanghai. Since both water availability and quality varies, here was an opportunity to solve two problems simultaneously. A closed system affords the company full control and the opportunity to decide the water quality.
