Frequently Asked Questions

Genoasis supplies a complete range including RO membranes (BWRO, SWRO, NF, UF, MBR, low-energy), FRP and composite pressure vessels, industrial pumps (centrifugal, multistage, submersible, borewell, AODD, sea water FRP, super duplex), filter cartridges, antiscalants and RO chemicals, sand and filter media, ion exchange resins, wastewater equipment (diffusers, MBBR media, tube settlers), UV and ozone disinfection, water quality instruments, valves and fittings, atmospheric water generators, and nanobubble generators.

We serve India (Chennai, Mumbai, Delhi, Bangalore, Hyderabad, Ahmedabad, Pune, Coimbatore and all major cities), UAE (Dubai, Abu Dhabi, Sharjah), Saudi Arabia (Riyadh, Jeddah, Dammam), Qatar, Kuwait, Oman, and Bahrain. Our Chennai head office handles India logistics; our UAE office handles GCC and Middle East supplies.

We respond within 6 hours to all enquiries. Email sales@genoasis.com, call +91 892 588 3227 (India) or +971 50 497 3835 (UAE), or use our contact form. For complex multi-product projects, detailed proposals with data sheets and lead times are issued within 24 hours.

Yes. We source from ISO-certified global manufacturers. FRP pressure vessels carry NSF/ANSI 61 and ASME certification; UV systems meet NSF/ANSI 55; RO membranes are manufactured to international standards; chemicals are available with COA, MSDS, and food-grade certification. Full documentation provided with every order.

BWRO elements (TDS up to 10,000 ppm, 99.5%+ rejection), SWRO elements (TDS up to 45,000 ppm, 99.7%+ rejection), nanofiltration (NF) for hardness and colour removal, ultrafiltration (UF) hollow-fibre modules (MWCO 10,000–150,000 Da), MBR membranes for wastewater treatment, and low-energy RO elements. Sizes: 2.5", 4", and 8" diameter × 40" length.

With correct antiscalant dosing, regular CIP cleaning, and good pre-filtration, membranes last 3–5 years. Replace when normalised permeate flow drops >15%, salt rejection falls below 98% (BWRO) or 99.5% (SWRO), or pressure differential rises significantly. We supply membrane cleaners and antiscalants to extend service life.

Yes. We specialise in replacement elements for existing systems across India — Chennai, Mumbai, Delhi, Bangalore, Hyderabad, and beyond. Share your current membrane brand, model, and vessel configuration (4" or 8") and we'll recommend compatible replacements with fast delivery.

Vertical in-line multistage pumps are the standard choice — compact, high-head, energy-efficient. For SWRO high-pressure service, FRP or super duplex stainless steel (UNS S32750) pumps resist chloride corrosion in seawater. Contact us with your flow rate, head requirement, and feed water chemistry for a specific recommendation.

Yes. We supply 4" and 6" stainless steel borewell submersible pumps for groundwater extraction. Widely used in Tamil Nadu, Maharashtra, Gujarat, Rajasthan, and Andhra Pradesh where borewell water feeds RO treatment plants. Stainless steel hydraulics ensure long service life in abrasive sandy well conditions.

For high-TDS, high-hardness borewell water (1,500–8,000 ppm TDS) common across India, we recommend a phosphonate or polymer antiscalant dosed at 3–5 ppm. Our technical team can perform scale prediction modelling from your water analysis report and prescribe the optimal antiscalant and dose. Share your water report for a free recommendation.

Yes. Both acid CIP (citric acid, HCl blends, EDTA-based for scale/metal oxide removal) and alkaline CIP (caustic, SDS, enzyme-based for biofilm and organic removal). Available in 25 L, 200 L drum, and 1,000 L IBC totes.

Fine bubble disc and tube diffusers for aeration, MBBR/SAFF carrier media for biological treatment, tube settlers and lamella plate clarifiers for sedimentation, screw press and belt press dewatering machines, and coagulants and flocculants for chemical treatment — for municipal STP, industrial ETP, and water reuse applications across India and the Middle East.

MBBR (Moving Bed Biofilm Reactor) uses suspended HDPE carrier media on which bacteria grow to treat wastewater biologically. We supply media with surface areas from 300 to 1,200 m²/m³ for BOD, COD, nitrification, and denitrification applications. Widely used in India and the Middle East for ETP and STP upgrades.

We supply UV systems from 1–5 m³/h for drinking water and small process applications up to 1,000+ m³/h for large municipal water and wastewater treatment plants. All systems are designed to deliver a minimum UV dose of 40 mJ/cm² (NSF/ANSI 55 Class A). Contact us with your flow rate and application.

UV provides instantaneous chemical-free inactivation of bacteria, viruses, and protozoa (including Cryptosporidium and Giardia) without forming chlorination by-products. However, UV provides no residual protection in the distribution network — many plants use UV as the primary disinfection step followed by a low-dose chlorine residual for distribution protection.
