Genesys Membrane Fouling Prevention and Removal Chemicals for RO Systems
Scale, biofilm, organic deposits, iron, and colloidal silica accumulating on RO and NF membrane surfaces reduce permeate output, raise operating pressure, and accelerate membrane replacement cycles. Genesys membrane fouling chemicals address both prevention and removal, targeting every foulant type across seawater, brackish water, and process water RO systems without damaging membrane polymer integrity.
Optimise water treatment with genesys membrane fouling chemicals. Effective for preventing and removing fouling in RO and industrial water systems. The range covers antiscalants, alkaline and acid cleaners, biocidal cleaners, flocculants, and UF-specific formulations under the Genesys and Genesol product lines for systems of every scale.
Dutco Tennant LLC supplies membrane fouling prevention chemicals from Genesys International across the UAE and GCC, serving contractors, consultants, and water treatment project developers.
Proactive Fouling Control and Targeted Cleaning
- Antiscalant dosing ahead of membranes prevents scaling from calcium carbonate, sulphate, silica, and metal ions before deposition occurs.
- Membrane Master software analyses feed water chemistry, enabling accurate antiscalant selection and dose optimisation during system design and operation.
- Flocculant pre-treatment reduces suspended solids and SDI, improving upstream water quality without introducing fouling-causing residues.
- Correct chemical selection minimises cleaning frequency, extending membrane life and reducing downtime and operational cost.
- Membrane autopsy services identify actual foulants, ensuring precise chemical selection for persistent or complex fouling conditions.

Types
Antiscalant and Antifoulant
Membrane fouling prevention chemicals in the Genesys antiscalant range dose continuously into the RO feed stream, inhibiting scale precipitation and sequestering trivalent metal cations before they deposit on the membrane.
- Genesys LF is a general-purpose phosphonate antiscalant for seawater and brackish water RO and NF systems, effective against a broad range of inorganic scaling species including iron and manganese
- Genesys SW and Genesys LS are phosphorus-free seawater antiscalants with Drinking Water Inspectorate registration, covering large municipal and potable desalination plant applications
- Genesys BS targets barium sulphate and high calcium carbonate scaling in process and industrial water RO systems where standard antiscalants do not provide adequate inhibition
Alkaline Membrane Cleaner
An alkaline Genesol cleaner uses blended chelating agents and non-ionic surfactants at high pH to remove organic foulants, colloidal deposits, and biological matter from RO and NF membranes.
- Genesol 34 is a readily biodegradable alkaline general-purpose cleaner that removes both organic and inorganic deposits, effective as a standalone cleaner or in combination with other Genesol products
- Genesol 704 targets aluminosilicate clay and aluminium-based foulants that resist conventional alkaline cleaners, covering systems using aluminium-based coagulants in pre-treatment
- Genesol 80 specifically addresses glycocalyx biofilm layers secreted by bacteria under stress, removing extracellular polysaccharide material that standard alkaline cleaners do not fully penetrate
Acid Membrane Cleaner
An acid Genesol cleaner uses self-adjusting low-pH formulations to dissolve inorganic scale, iron oxides, and metal hydroxide deposits from RO, NF, and UF membrane surfaces.
- Genesol 38 is an inorganic scale cleaner and iron deposit remover approved for drinking water applications, with self-adjusting pH maintaining optimum iron salt solubility throughout the cleaning cycle
- Genesol 37 combines inorganic scale and iron oxide removal with organic deposit cleaning capability, covering severely fouled systems with mixed inorganic and organic foulant layers
- Genesol UF Fe is a low-pH cleaner formulated specifically to remove iron and manganese fouling from UF membranes on SWRO pre-treatment systems where iron loading from feed water is high
Biocidal Cleaner
Biofouling removal chemicals in the Genesol biocide range eliminate active bacterial colonies and biofilm from RO and NF membrane surfaces and associated pre-treatment pipework, pumps, and tanks.
- Genesol 30 is a fast-acting, broad-spectrum RO membrane fouling removal biocide used on-line and off-line to eliminate microbiological fouling, deactivated safely using sodium bisulphite after treatment
- Genesol 32 operates as both a membrane cleaner and a pre-treatment system biocide, controlling biofouling in storage tanks, dosing pipework, and pre-filter housings alongside membrane treatment
- Non-oxidising formulations throughout the biocide range are membrane-compatible, avoiding the irreversible oxidative damage that chlorine-based biocides cause to polyamide composite membrane elements
Flocculant and Ancillary Products
Genefloc and ancillary Genesys products support pre-treatment performance, reducing the foulant load reaching the membrane and improving the effectiveness of antiscalant and cleaner dosing programmes.
- Genefloc GPF is a general-purpose flocculant for surface, well, and process waters with medium to high SDI values, reducing colloidal and suspended solids loading without introducing membrane-fouling coagulant residues
- Neutral pH Genesol 61 cleaner removes organic and inorganic foulants from RO and NF membranes at mid-range pH, covering systems where health, safety, or effluent disposal restrictions prevent high and low pH chemical use
- Genairclean delivers a revolutionary air-assisted membrane cleaning approach, using controlled air scouring combined with chemical contact to dislodge compacted deposits from lead elements without increased CIP chemical concentration
Standout Features & Benefits
Proven Foulant-Specific Formulations
- Each Genesys and Genesol product targets a defined foulant category — scale, organics, biofilm, iron, or colloidal particles — preventing the ineffective cleaning that results from using a non-matched general-purpose product
- Membrane autopsy analysis before selecting a cleaning protocol ensures foulant deposits are correctly identified, avoiding repeated cleaning cycles that fail to restore normalised performance
- Staged cleaning protocols combining alkaline first and acid second address mixed fouling conditions in a single CIP event without foulant cross-precipitation between cleaning stages
Membrane-Safe, Biodegradable Chemistry
- All antiscalant and cleaner formulations are tested against polyamide, cellulose acetate, and polysulfone membrane materials, confirming no measurable change in salt rejection or membrane morphology after repeated use
- Readily biodegradable classifications across Genesol 34 and biocidal cleaners support compliant waste stream disposal through standard wastewater treatment without specialist effluent neutralisation
- Biofouling removal chemicals in the non-oxidising Genesol biocide range deactivate to harmless by-products using sodium bisulphite, meeting potable water safety requirements after off-line membrane treatment
Reduced Operating and Capital Cost
- Correct antiscalant selection and dosing extends the interval between CIP cleaning cycles, reducing chemical consumption, labour, and production downtime across municipal and industrial RO plants
- Genesys membrane fouling prevention maintained through proactive antiscalant dosing delays membrane element replacement, lowering capital expenditure on large multi-vessel RO systems significantly over the plant design life
- Membrane Master scaling prediction software eliminates trial-and-error antiscalant selection, reducing the risk of under-dosing that causes irreversible scaling and over-dosing that increases chemical cost unnecessarily
Broad System and Feed Water Compatibility
- The antiscalant range covers seawater, brackish water, wastewater reuse, and high-hardness process water feed sources within the same Genesys product family without requiring non-standard formulations
- RO membrane fouling removal cleaners in the Genesol range are compatible with all standard CIP system configurations, PVC and stainless steel pipework, and fibreglass and steel tank construction without accelerating corrosion
- UF-specific cleaner formulations extend the same foulant-matched chemistry approach to hollow-fibre UF pre-treatment systems, providing a single chemical supplier for the full membrane train
