Following a career of more than 20 years in the metal industry, Mr. Viljo Järvenpää founded Wiser Oy in 1986. Mr Järvenpää is a Finnish metallurgical engineer who specialises in chemistry as well as in mechanical engineering. Above all, he is a passionate researcher and inventor, who holds 100 different patents.
At Wiser Oy, we provide our clients with the opportunity to increase their productivity, improve working conditions and control environmental discharges. We are able to deliver tailored solutions for the purification of water and flue gases and the treatment of dust air. And our range of technologies is maintenance free, reliable and energy-efficient, with many of them being internationally patented.
Engineering is an essential aspect of our services and know-how at Wiser Oy. We carefully consider an integrated approach to the needs of our clients as a prerequisite for fulfilling the increasingly stringent environmental stipulations and achieving economic targets. Consequently, in addition to our manufacturing the equipment, Wiser Oy will also work on the process design, supervise the installation and provide training for operation and maintenance, start-up and guarantee period.
Since 2005, Wiser Oy has been a part of Troll Capital Ltd. This is a group of companies owned by the Paananen family, who are based in Lahti, . Mr. Jalo Paananen is Chairman of the board of Wiser Oy. The other board members are Dr. Mari Pentsar-Kallio and Mr Elmar Paananen.
Our new ownership structure has given Wiser Oy the opportunity to achieve more vigorous growth. We anticipate that total revenue for 2007 will reach 2.5 million Euros, double the figure of 2006

| Wiser treatment of dust air The treatment of dust air from crushing, quarrying and explosion is another major application area of the Wiser scrubbing process. In such instances, the scrubbing will greatly reduce smoke hour, allowing more time for actual production and greatly improving working conditions. The Wiser scrubbing equipment can also be used for drop separation, odour elimination and air-conditioning.
The Wiser know-how of water treatment represents a basis for the use of excessive water in Wiser scrubbing â therefore, it ensures high efficiency of the Wiser scrubbing process. Water used in scrubbing is treated with Wiser dissolved air flotation and circulated so that additional clean water is not required.
In the field of gas and dust air treatment Wiser Ltd has proudly provided our services to Altia Corporation, Boliden Kokkola Oy, Genencor Oy, OMG Harjavalta Nickel, Oy Ovako Wire Ab and YIT Environment Oy and many more. | 
| Wiser water aeration While conventional aeration methods are based on spraying water into the air or the running of water, the function of the Wiser aerator is based on the intensive mixing of air into water. The Wiser aerator contains a patented rotor and the aerator is designed to simultaneously sucks air (or any other gas, as required) and water into the rotor from different directions and disperse the gas into the water. The rotor reaches about half a metre into the water and joined with a suction tube it is possible to reach the bottom of a deep tank or any desired point of aeration.
It is possible to install the Wiser aerator either standing on the edge of a water tank or on a anchored pontoon for floating. The motor remaining above the water surface is protected under a case and in this instance it is also possible to install intake air preheating for outdoor function during winter.
The Wiser aerator can operate as a blender only, in which case it breaks up solid substances into water, homogenises and emulsifies as necessary. It is possible to create pressure conditions as high as 1 bar with the use of the Wiser aerator. The construction material for the aerator can be chosen according to process.
Wiser aerators are available of capacities from 10 to 300 m3/h of water. Free intake air amount can vary from 0 - 5 % of water
