Water Treatment

water treatment

We offer a large portfolio of water treatment services and solutions for wide range of source water (groundwater, surface water, brackish water and seawater) 

What is great about FARAN Water Treatment services is that solutions are customized and they will give you the full treatment that will help with your decision on the different types of water treatments available to you. They will take the time to go through with you, step by step, the different types of water treatments process, and a service representative from FARAN Water Treatment Services, will give you options that will help you decide on what works best.

Whatever water source you have, we will help to solve water quality problems. A variety of water treatment systems have been designed and installed properly by our team of professional technicians.

Desalination Water Treatment

Desalination has become a very affordable solution to cope with fresh water shortage specially in tropical as well as of off-shore areas. Reverse osmosis (RO) is the leading pressure driven membrane processes which can be used for seawater or brackish water desalination. Every SWRO or BWRO unit shall be safeguarded with proper pretreatment. Desalinated water would be re mineralized in post treatment unit for potable purposes.

The reverse osmosis process can be built with one or two passes, depending on the product water requirements and the seawater salinity and temperature. In most cases, 1 pass is sufficient to reach the EU drinking water standards, specially regarding the boron content (1 mg/L). To reach WHO boron guideline (0.5mg/L), a second ass might be necessary (Boron removal process).The energy recovery device is the key factor that determines the plant electrical costs. It must be chosen carefully based on the local energy costs and environment policies.

Post-treatment and/or polishing steps are required to condition the water after the reverse osmosis membrane process to make it suitable to your application.

The art of desalination is to determine and combine available technologies to optimize water production costs and quality. Faran Company offers optimum process solutions for SWRO and BWRO plant from seawater intake to storage tank as turnkey project to produce high quality drinking or process water.

Pretreatment System

The efficiency of pretreatment for RO feed water depends on the source and quality of the seawater feed. A correct design of the system is the key for a successful operation of the SWRO plant.

Pretreatment is essential for the proper operation of the SWRO equipment and can add substantially to the project's CAPEX and OPEX since higher load of suspended solids, colloids and/or biological growth can cause unwanted fouling on the RO membrane if not treated properly.

Inadequate or inappropriate pretreatment may result both in a decline of water production and in the deterioration in product quality. The main result of a failed pretreatment is the RO membrane fouling with consequently increases in membrane replacement and chemical treatment. As a consequence of high fouling conditions, an increase in salt passage is registered while a higher feed pressure is required to maintain the design flow.

The aim of the sea water pretreatment system is to reduce the fouling constituents in the feed; a proper pretreatment system should remove colloidal and particulate matter and control the formation of chemical and biological deposits in order to reach a value able to provide stable and long term performance of the RO membranes.
