Pullner Is Your Premier Filters Manufacturer For Desalination Plants Filtration


Desalination Plants Filtration Solutions

Water is an indispensable basic substance for human survival and production. Seawater desalination technology is an important means to solve today’s water scarcity.

Seawater desalination technology refers to the process of removing excess salt and minerals from water to obtain fresh water. In the field of seawater desalination, pretreatment is the key to ensuring long-term stable operation of the reverse osmosis system. 

The reverse osmosis system needs better pretreatment to reduce the turbidity of seawater and prevent the growth of bacteria, algae and other microorganisms in order to ensure the quality of the effluent. If the influent water quality is poor, the water production rate is very low. 

Therefore, seawater must be pre-filtered before it enters the reverse osmosis membrane device.

Pullner’s high flow filter is used as pre-filters for desalination reverse osmosis, protect the RO membrane and save cost for customers.
