PermaTreat PC- 191T – a highly efficient scale inhibitor

PermaTreat PC- 191T serves as a Membrane Antiscalant manufactured by Nalco Company that successfully amalgamates the product reliability of PermaTreat PC-191 with the built-in technology for advanced control and monitoring. PermaTreat PC-191T - a highly efficient scale inhibitor, whose active components were developed for the purpose of carrying out treatment of reverse osmosis (RO) membrane systems. PermaTreat PC-191T, for over 20 years, has shown commendable performance against the following scalants:  calcium sulfate, calcium carbonate, calcium fluoride, barium sulfate, strontium sulfate, silica and iron.

Reverse Osmosis is regarded as a process that involves deionization and demineralization of water by passing it under pressure through a semi-permeable membrane. Filtration of effluent water by the use of the reverse osmosis membrane accompanies some unavoidable issues that tend to disrupt the productivity of the membrane which includes some major concerns such as degradation, fouling, and scaling of membranes. Scaling and iron fouling of the RO membranes will affect the performance of the system and results in premature membrane replacement. Precipitation of scale and deposits build up on the RO membrane, which leads to poor permeate quality, low permeate production, increased water consumption, unscheduled downtime and increased energy costs.

Membrane Antiscalants pose as specialized formulation that aids in strengthening the solubility of sparingly soluble salts which can be referred to as common scalants. These membrane antiscalants form a crucial factor in the effective and organized operation of the reverse osmosis system.

PermaTreat PC- 191T appears to be a yellow colored liquid having an ammoniacal odor. It has a specific gravity of 1.36 and exhibits pH of 10.5. PermaTreat PC- 191T finds its use in areas of high salt content water.

Benefits:

• It helps in reducing membrane fouling and the frequency of washing

• Nalco uses the TRASAR technology for its formulation

• Reduces the acid consumption

• It is applicable to all types of films and is more efficient than the phosphate

• It improves the water quality which account for different benefits
