Polyelectrolyte preparation and dosing system CONTINUFLOC V9, mother tank, dosing station for polymer solution and dilution
Mother tank and dosing stations are used for feeding additives (wet strength agents) in the production process of tissue paper. Dosing of the retention agent in the production process. The neat polymer solution, prepared with CONTINUFLOC V9 preparation and dosing systems, is used for process water treatment.
Mother tanks and dosing stations for the supply of additives (wet solids) in the production process of sanitary paper
Alltech delivered mother tanks and dosing stations to Vajda Papír as early as May 2022 during the course of the first project phase. As part of the production process of the sanitary paper, various additives are dosed whose task is, among other things, to increase the wet strength properties. Additives also serve to improve the retention of solids on the paper machine wire and drainage during the manufacturing process.
The mother tanks supplied by Alltech function as storage and dosing system for the safe and efficient handling of standardized IBCs (industrial bulk containers). These chemotainers are positioned directly on the tank with the help of a forklift truck or an appropriate lifting device and are emptied into the tank completely. The volume of the mother tank permits the emptying of a complete chemotainer with a fluid reserve of 10-50 percent. In this way, a continuous supply to the dosing system is ensured, and the timing of the transfer process does not have to be monitored precisely.
The mother tank is located in a collecting bund, which protects the operating personnel and the production environment from chemicals in the event of a leak. The dosing stations are mounted on a wall mounting plate or floor mounted and are used for dosing chemicals into various process sections of the paper production.
Preparation of neat polymer and dosing of the retention agent into the manufacturing process and for process water treatment
During the paper production, the components, which will later become the paper, are applied to a sieve as a diluted, watery slurry and filtered. This process of filtration is improved and partly accelerated by retention agents.
In a second project phase, Alltech delivered another mother tank and a CONTINUFLOC dissolving and dosage system with EMMI (an electromechanical mixing system to save polymer concentrate), as well as three dosing stations. One dosing station supplies the flotation system (DAF) with a polymer solution for the treatment of process water. The two other dosing stations supply the paper machine with a polymer solution.
CONTINUFLOC systems are fully-automated two-chamber pendulum systems for polymer preparation. For specific applications with an increased requirement, the CONTINUFLOC can also be equipped with an EMMI electromechanical mixing system. This is characterized by an optimum concentrate mixture and, therefore, maximum efficiency. This results in reduced material and resource consumption. The dissolving and dosing system used at Vajda Papír provides a maximum of 4,000 liters of ready-to-use polymer solution per hour.
