Membrane Treatment

Sicagen’s Reverse Osmosis (RO) membrane treatment process is used to separate the purified water from the contaminated water thus improving the quality of the water. RO membrane is cellophane like membrane which acts like a filter to remove micro-organisms which are too large to pass from the pores of this membrane. This process is a technology of liquid filtering that is used to get clean water either to convert blackish water in industrial process, to recover salt or to clean waste water. RO membrane materials mainly include polyamide thin film composites, cellulose triacetate and cellulose acetate as hollow fiber bundled together or spiral wound around tube. Along with our own solutions, our team deals with membranes developed by various Ro Membrane Manufacturers in India. Some of them include TFC RO Flat Sheet Membrane, Hollow Fiber Membrane, Nano-filtration Membrane, Flat Membrane Filters, Conventional Filtration Membrane and RO Microfiltration Membrane. We also offer solutions related to low pressure, sea water elements and brackish water treatment. Apart from that, the membranes we recommend are effective in removing ions, virus, pathogens, pyrogens, molecules, bacteria and other larger particles at the point of use. We are aligned with the best practices around the world for reverse osmosis process which is used to treat domestic as well as industrial water.

Bio Control
Always verify regulatory requirements and membrane compatibility before implementing a biocide program. Contact us for more information.

Biofouling is inevitable in every membrane system; however, using our biocides you can minimize the impact of biogrowth on the operation of your RO system. The right biocide program can reduce your need for membrane cleaning, reducing your overall cost of operation. Our biocides are membrane safe and can be used online or offline.

Membrane Bioreactors (MBR) combines’ membrane separation process with biological treatment of wastewater.

The MBR technology has several advantages over conventional biological treatment:

  • Provides high quality effluent suitable for recycle
  • Reduces land requirement by 50%
  • Lowers bio-sludge production
Our team can help determine the cleaner that will work the best for your application.

Membrane cleaning is an important part of any reverse osmosis, nano-filtration, ultra-filtration, or micro-filtration maintenance program. For membrane cleaning, our Membrane Solutions Group offers a range of products, which are acid- and alkali-based cleaning chemicals designed to remove most foulants and restore performance in all types of membrane systems. Our products are approved by the world’s leading membrane manufacturers, have been formulated and tested at our research laboratories, and have been proved in numerous operating systems around the world.

Water pretreatment can help prevent fouling and scaling. Our pretreatment coagulant chemical product line, was designed to be used in front of multimedia filters to improve the performance of the filter, reducing SDI and decreasing membrane fouling for reverse osmosis systems.

The end result?

  • Improved operation of filtration systems and clarifiers, and better downstream operations in the membrane system, reducing your total cost of operation.
  • To determine the right filter aid for your feed water and equipment, onsite testing is required. We evaluate which product will achieve the best results for you.
Post Treatment
Sicagen Specchem offers a selection of products that can help you maintain optimum feed water conditions to and from your membrane system.

We offer products including dechlorination products and alkalinity source products.

Scale Control
Sicagen Specchem Membrane Solutions team offers wide ranges of antiscalant products for different types of scale.

Our scale inhibitors can save you money by:

  • Preventing the need to replace expensive membranes prematurely
  • Maintaining efficient plant operation at the highest possible recovery
  • Eliminating or reducing the use of hazardous acids
  • Reducing water consumption by safely operating at high recovery rates
  • Using fewer chemicals
  • Producing less concentrate, and allowing for better environmental acceptance of that concentrate
  • Reducing energy costs
  • Reducing the downtime caused by frequent membrane cleanings
  • Whether you’re from a municipal organization that must produce large volumes of clean water, or from an engineering firm that wants to design reverse osmosis systems to operate at higher recoveries, or from an industrial operation, we can provide the right antiscalant that will be cost effective and will prevent mineral scaling of your membranes.
