Veolia Hydrex 4731 Membrane Cleaner – 25 kg

Description

Veolia Hydrex 4731 Membrane Cleaner is a professional water-treatment chemical supplied in a 25 kg container for membrane cleaning programmes. Cleaning chemistry must be selected after reviewing the foulant, membrane compatibility and current manufacturer instructions.

Veolia Hydrex 4731 Membrane Cleaner in Oman

RO membranes accumulate deposits during operation. The symptoms may include higher differential pressure, lower permeate flow or reduced salt rejection. A planned clean-in-place programme uses suitable chemistry, concentration, temperature, pH, flow and contact time to remove compatible deposits without damaging the membrane. UV Water Systems supplies Hydrex 4731 in Oman and supports RO operators with membrane cleaning and maintenance.

Product features

• Veolia Hydrex professional membrane-cleaning product.
• 25 kg pack for commercial and industrial RO maintenance.
• Suitable for use within a controlled clean-in-place programme.
• Liquid chemical format for measured preparation and circulation.
• Available with local RO service support from Muscat.

Typical applications

Hydrex 4731 may be considered for membrane systems used in hotels, factories, hospitals, laundries, food-service facilities and process-water plants. Product selection must reflect the identified foulant and membrane manufacturer’s chemical limits. A cleaning solution that is suitable for one deposit may not be suitable for another.

Technical information

Cleaning and safety

Do not start cleaning from the product label alone. Review the current technical data sheet and safety data sheet, identify the likely foulant, and confirm membrane compatibility. Trained personnel should establish dilution, pH, temperature, recirculation flow and contact time. Isolate and flush the system as required, wear specified personal protective equipment, and dispose of spent solution according to local requirements.

When membranes need cleaning

Cleaning is driven by data, not by the calendar. Normalise the plant readings and clean when normalised permeate flow drops by 10 to 15 percent, differential pressure across a stage rises by 15 percent, or salt passage increases by 10 percent from the commissioning baseline. Leaving a fouled element in service makes the deposit harder to remove and shortens membrane life, so acting on the first clear trend is cheaper than waiting.

Matching the cleaner to the foulant

Reverse osmosis foulants fall into broad groups. Carbonate and sulphate scale, metal oxides such as iron and manganese, organic matter, biofilm and colloidal silt each respond to different chemistry, and using the wrong product can set the deposit rather than remove it. Autopsy data, feed water analysis and the pattern of the performance loss across stages usually point to the dominant foulant. A two stage clean is common where more than one mechanism is present.

Running a clean in place cycle

• Flush the vessels with permeate or good quality product water before introducing chemical.
• Mix the solution in the CIP tank to the concentration and temperature limits given by the membrane manufacturer.
• Circulate at low pressure and the recommended flow per vessel so the deposit lifts rather than compacts.
• Soak, then recirculate again, watching pH and solution appearance for signs the clean is working.
• Flush thoroughly and run to drain until the permeate conductivity settles before returning to service.

Handling and supply in Oman

Stay inside the membrane manufacturer limits for pH, temperature, flow and exposure time, because exceeding them can damage the element permanently. Confirm compatibility and dose from the current technical data sheet and safety data sheet, use chemical resistant CIP equipment, and give the work to trained staff with the protective equipment named in the safety data sheet. UV Water Systems supplies Veolia Hydrex 4731 Membrane Cleaner with CIP skids, membrane replacement and RO servicing across Muscat, Sohar, Salalah, Duqm and Nizwa.
