Advanced Filtration Solutions for Chemicals and Solvents


In processing both industrial and consumable chemicals clarity and purity is of the essence. To achieve this – it is crucial to implement effective filtration techniques, and filtration equipment engineered to withstand the operating conditions of chemical processing. It is also important that the application requirements are closely analyzed and a perfect plan is formulated to optimize the processes and ensure filtration excellence. In addition to all this, availability of the best filtration equipment and easy, quick and transparent process of buying these filters is paramount.


Think Filtration Think Gopani


From processing of highly volatile chemicals, reactive solvents and corrosive liquids to stripping of catalysts and recovery of precious metals, we have the perfect combination of filtration products and consumables for all your applications.


Worried about frequent mechanical seal leaks and HTF loss?


Ignoring the health of your heat transfer fluids often leads to quality deterioration, and will have an impeding effect on the entire process. Knowing what causes the quality of these fluids to deteriorate is your first step to resist these attacks and optimize the efficiency of these fluids Filtering out these contaminants from the heat transfer fluid will increase the service life of HTF and reduce the frequency and cost of maintenance – hence reducing your CAPEX/OPEX.

Difficulty in filtering high viscosity mastics and sealants?


High viscosity sealants and mastics are used as an adhesive to bind expensive engine parts, they prevent water ingress and corrosion of joints. The quality of these viscosity mastics and sealants cannot be compromised, and hence a compatible filtration system is crucial. In order to produce a high-quality end product, operators can turn to high pressure filtration systems with specific particulate removal capabilities, high dirt holding capacity and materials that are compatible with highly viscous substances. Gopani has developed specialty filter housings and compatible cartridge filters for processing highly viscous and waxy solvents – that can be customized to suit individual needs.


Not achieving desired filtration output due to non-compatibility of filtration products?


Achieving desired output and optimized filtration processes is all about implementing a system of filtration products and consumables that are compatible. Manufacturing our own filtration equipment allows us to tailor products using duplex, super duplex, C22 and stainless steel. Additionally, we also enhance product compatibility by treating surfaces to avoid contaminant retention on them. Small details like part number coding, clamp closure or seated Buna-N/Silicon/Viton ‘O’ ring sealing go a long way and result in eliminating accidental misplacement, lower pressure drop at high flow rate, zero bypass, longer service life and more.

Aspire to maximize recovery of precious metal from spent catalyst?


Many chemical, petrochemical and pharmaceutical processes use catalysts bearing precious metals like platinum, palladium, rhodium and gold. After repeated usage when the catalyst becomes totally deactivated, precious metals are recovered from the catalyst and its value is maximized. At every step of recovery, filtration is one of the prime requirements. The extraction is done in multiple stages ensuring recovery to +99.95%.

Our experts have extensively worked with special metal recovery units, and have vast experience and understanding of problems that may slow down or adversely affect the recovery process. We have a wide range of filtrations solutions specific for applications across the whole process and every step of Catalyst Recovery.

For best results in precious metal recovery from spent catalysts

Low solvent recovery is eating into your profit margins?


Solvents loss is a key factor affecting the cost of production.  An efficient solvent recovery process brings these costs down. As a result, manufacturers take stock of Kilograms of solvent lost against the kilograms of production regularly, keep an eye on solvent losses and take the needful steps to optimize recovery.

Solvent recovery experts at Gopani, can help you select a premium grade activated carbon variant for solvent vapor recovery system. Our team also offers guidelines for parameters like Superficial Velocity, contact time, isotherms of various solvents, absorption capacity and expected life of Activated Carbon.


Handling corrosive liquids and reactive chemicals?


Reactive chemicals and corrosive liquids range from acids to alkalis to oxidizing agents and transition metals. All these substances are extremely harsh, and only a corrosion resistant material can survive contact. Hence it is important that when filtration process involves contact with reactive or corrosive liquids, a filtration system that is made of resistant material or coated with material that repels these chemicals and does not let them react with the material of the housing or the filter cartridge is crucial.

Gopani manufactures a wide range of filter housings and consumables that are immune to chemical degradation and resistant to reactive liquids. Our team can analyze your requirement and suggest a suitable variant.

Need to solve cooling tower water treatment issues?


Cooling towers are the most cost-effective as compared to other cooling mechanisms. However, they too have their share of problems like high amount of blowdown, secondary waste treatment issues and efficiency issues. To make the process problem free – it is extremely important to choose the right cooling tower water treatment systems. Better feed water filtration, high quality side stream filtration, and filtering out scale and corrosion causing impurities is crucial.
