The Permionics Advantage Towards Sustainable Zld

Permionics has introduced the revolutionary concept of directly treating the effluent through membrane systems and recycling of water.
We have developed special low fouling hydrophilic membranes having high COD and BOD tolerances. These membranes can handle high TDS and SS loads and can take in TDS and COD of about 40,000 ppm directly.
The Perma HPA elements are the only one of its kind in the membrane market to withstand high COD and BOD loads, outperforming the conventional RO,/NF membranes available in the market today.
The smooth surface and it’s near neutral to negative charge give the added advantage of it being resistant to biofilm formation and fouling.
Our effluent treatment systems have been supplied for treating effluents from Textile, Dyeing, Biotech & Pharma, PCB manufacturing, Vegetable Oil Manufacturing, Pesticides Industries, Oil & Gas etc. The supplied staged systems enable recoveries of 80 to 95% of the wastewater.
Our membrane systems clubbed with an evaporator will make an industry almost zero-discharge industry thereby reducing pollution-related problems and making the company eco-friendly.


Permionics has spearheaded the innovation of membrane development and their applications in various separation processes providing customized solutions across the filtration spectrum. We have seen the influx of hollow fiber Ultra and Micro filtration in the pre-treatment of RO/Resin systems.
With the development of our tight UF chemistry and a robust membrane module, the HFUF05 membrane is by far a more comprehensive solution than Hollowfibre elements, especially when it comes to removal of COLLOIDAL SILICA, TURBIDITY, and RESIDUAL COLOR from treated sewage apart from lowering the BOD AND COD to achieve the stringent regulatory norms of 5 & 5. With its hydrophilic neutral surface and tight pore size, it removes residual organics such as humid acids, BOD and COD due to fecal contamination in treated sewage, surface and river water feeds. This is an indigenous membrane developed in house at Permionics, tried and tested on effluents, STP outlets and surface waters with excellent results. We would like to introduce TURBO-CATCH System as a polishing treatment system when you need to recycle treated sewage water for further use.
This followed by our NF or RO systems can convert Treated sewage into BOILER FEED Water if not DRINKING Water.


Different Industries with different processes land up at different waste /wash stream/effluent characterized by the TDS, COD, BOD, Turbidity and thus the treatment scheme for each also varies. The design of a comprehensive recycling system is Zero Liquid Discharge (ZLD) situation where the final evaporated and dried solids. It is a combination of membrane/non-membrane biological processes viz. UF pre-treatment followed by pre-concentration by RO and then the evaporator. As we go down the treatment scheme, the capital costs, as well as operating costs, increase exponentially–evaporation being the most expensive. The versatility of membrane technology and the ranges of separation gives the flexibility to achieve the maximum efficiency and reduce operating cost not only for membrane parts but by bringing down overall load.

Our Advantage

Spiral Wound Membrane elements consistently demonstrate superior performance and life on brackish and seawater sources as well as in tertiary wastewater treatment. Spiral wound membranes require generally less pre treatment and have fewer operational problems.


We also undertake Trouble shooting, Revamping and subsequent O&M facility. A division for large scale water and waste water recycling facilities on BOO basis is also a unique business model that Permionics has embarked on.
