CTG provides a range of additional membrane products which include flocculants for RO feed water optimization, biocides for online dosing and off line sanitization, all products are compatible with all Brand membranes. In addition, we also will supply formulated chemicals for chlorine reduction and corrosion protection in permeate supply lines.

 

Biocide	Biofilm control – on line dosing and CIPBiofilm control, off line sanitization and membrane storage
Flocculant	Membrane compatible flocculantsMembrane compatible flocculant, potable grade
Flocculant, algaecide & Biocide	Flocculant with additional biocide and algaecide activity for on line use
Chlorine Scavenger	Removal of residual chlorine from feed water
Corrosion Protector	Corrosion inhibitor for permeate distribution systems
Cleaners	Successful membrane clean depends primarily on the nature of the foulant. Before electing cleaning chemicals and designing a cleaning protocol it is vitally important to correctly identify the deposit or foulant trough a RO feedwater proper lab analysis and Membrane Autopsy Service. For the most effective cleaning, and therefore reduced cleaning frequency, conditions of pH, temperature and contact time are important.

Due to a different RO feed water ionic composition, it is necessary to have a proper lab analysis. As a result, different types of scale may deposit on the membranes if the correct antiscalant and/or dosage is not used. To provide optimum operating conditions for both Sea and Brackish Water RO plants, it is imperative to select the correct antiscalant. Correct product application in the RO feed water is critical to ensure the optimum plant operational performance is possible, reduce the overall costs through energy savings, reduced cleaning frequency and extend the life of the membranes.

Antiscalants	Main Application
Sea Water Chemicals	Large systems, first and,second pass, partial recycling.,Potable use - NSF/UKDWI, Small / Medium Systems. Potable use - NSF/UKDWI Phosphorous free High sulphate  Second pass (Brackish water portion of boron), high pH, high recovery
Brackish water Chemicals	Broad spectrum, stressed water. Potable use - NSF/UKDWI High Calcium Sulphate Strontium Sulphate High silica feed High phosphate Systems incorporating concentrate recycle for small systems Mains feed water. Contains dechlorinator to prevent membrane oxidation Broad spectrum, large municipal plant. Potable use - NSF approved

 

 

 

 

 

 Cooling Water Systems transfer heat from one substance to another.

Normally, Cooling Water Systems are open to the atmosphere at the tower. As the water recirculates in the Cooling Tower, heat gained by the process is released by evaporation. The cooling water then returns to the heat exchangers to pick up more heat.

Cooling Water System tend to develop problems such as Scale, Fouling and Corrosion. These problems can cause:

It is possible to select the correct Cooling Water program treatment to provide optimum operating conditions for heat exchangers and avoid problems. We offer technical evaluations for these which include:Mechanical, Operational and Chemical evaluations onsite.

 

 

 A poor treated steam boiler is a potential high risk in the plant, so getting the correct feed water quality and boiler water chemistry is critical. A complete water treatment program for a steam boiler will usually include an Oxygen scavenger, internal treatment and a condensate piping treatment. A successful water treatment requires:
