Chemical Enhanced Backwash (CEB, Clean-in-Place Enhanced Backwash) is a method of deep cleaning of filtration systems, which is used to remove contaminants that cannot be removed by standard backwash. Using CEB makes it possible to extend the service life of filters and membranes, reduce maintenance costs and increase the efficiency of water treatment plants.
The chemical enhanced backwash process consists of several stages:
- Backwashing – initial removal of mechanical contaminants using a water flow. The minimum speed depends on the type of membranes.
- Adding chemical reagents – injection of cleaning compounds designed to dissolve organic and inorganic deposits.
- Soaking – maintaining the system in static mode to maximize the effectiveness of the reagents.
- Washing – removal of reagent residues using filtrate. The speed depends on the type of membranes.
Advantages of using CEB:
— Deep cleaning of filters from complex contaminants that cannot be removed by standard backwashing.
— Extended service life of equipment due to effective removal of deposits.
— Reduced operating costs due to reduced frequency of filter and membrane replacement.
— Process flexibility – the ability to use a variety of different chemical compositions depending on the nature of the contaminants.
All parameters associated with CEB, including soaking time, reagent concentration and washing duration, are set in the control system. This ensures consistent cleaning quality, reduces the impact of human error and increases the efficiency of equipment operation.
Regular chemical enhanced backwash makes it possible to maintain water treatment systems in good working order, ensuring their reliability and high productivity.
