Filtration system
for conversion treatment solution
Sanshin has supplied the Model FK for sludge treatment of conversion treatment solutions since 1970. More than 1,000 units have been operated not only inland but also overseas.
Recently, higher quality of product is required due to high rejection rate of various new chemicals in pre-treatment line of painting, therefore, higher filtration degree is demanded in the market.
The combinations of Model FD and FK or FD and PF are the most suitable filtration systems to perform satisfactorily to clarify conversion treatment solutions.
Features
- Solid concentration is controlled lower.
- Reduce tank cleaning and acid rinsing frequency.
- Effective washing in a few minutes.
- Drainage is recovered when combined with Model FK or PF, and dewatered cake discharged automatically.
