Water Treatment Plants

---

Membranes in any membrane separation system are the heart of the water treatment plants and the process.  Suspended solids, microorganisms and mineral scale can foul membrane elements.  These deposits can cause loss in output and/or rejection levels and reduce total system performance. 

Fouling is attributed to scaling due to mineral deposits, fouling of suspended solids, and microbial fouling or development of biofilm due to growth of bacteria in the system.

The performance of an RO plant can be improved by good pre-treatment to remove suspended solids, colloidal matter and other impurities & chemical solutions.

Our technical services include

• Analysis of water samples and provision of scientific reporting
• On site cleaning services

Our products have been specifically developed for all types of systems and feed water quality and offer significant cost, safety and operational flexibility and benefits. The range comprises of:

Antiscalant

Based on the solubility of some salts, these tend to deposit on  membranes when water passes through the membrane surface. These salts  precipitate on the surface causing fouling and hence affect output. 

Our range of high performance antiscalants have been specifically developed to meet the following criteria

• Excellent scale inhibition
• Effective across a wide pH range.
• Compatibility with membranes
• Compatible with other products.
• Cost effective.
• Safe to handle and safe to use.

Membrane Cleaners

A corrective and preventive membrane program of an RO plant must use  high performance membrane cleaners. Usually membrane cleaning is  implemented when operating parameters, flux, conductivity or ∆P (differential pressure) change siginificantly. It is advisable to clean  at an early stage of fouling because foulants may be difficult to clean  later or the damage may be permanent to the membrane.

Our range of cleaners include  

• Low pH cleaner
• High pH cleaner
• Neutral pH cleaner
• Special silica cleaner

Biocides

 Non-oxidizing biocides are used either in a cleaning program or  during normal operation of an RO plant. Dosage typically depends on  extent of micro fouling as well as the frequency of membrane cleaning  and equipment downtime. 

Our Bioguard range of biocides are specifically formulated and compatible with all types of membranes
