Integrated wastewater treatment systems for reuse, recycling, sewage treatment, and zero liquid discharge — engineered for compliance, reliability, and long-term performance. From effluent characterisation to commissioning and O&M.
Our technical team evaluates wastewater characteristics, reuse goals, and discharge requirements before recommending the right solution.
Wastewater treatment converts industrial and municipal effluent into water that is safe for discharge or suitable for reuse. Systems differ significantly in scope and purpose — and no two industrial wastewaters are identical in composition or load. CLEANFLO integrates wastewater analysis, process engineering, chemical treatment, and laboratory monitoring to deliver systems that perform reliably long after commissioning.
ETP treats industrial process effluent for safe discharge or reuse. STP treats domestic or mixed sewage for compliance and reuse. ZLD eliminates liquid discharge entirely, recovering maximum water for recycling and concentrating solids for disposal.
Wastewater composition varies dramatically by industry, process, and season. Generic designs fail because they don't account for actual pollutant loads. CLEANFLO's designs start with effluent characterisation — not catalogue selection.
CLEANFLO combines physical treatment, biological processes, chemical dosing, membrane technology, and lab-backed monitoring into a cohesive system — with ongoing O&M support to ensure the plant performs across all operating conditions.
Every CLEANFLO wastewater treatment solution begins with sampling, laboratory analysis, and a site survey — not a standard design template. This means the right technology is selected for your wastewater, your discharge requirement, and your reuse objective.
CLEANFLO designs and delivers a comprehensive range of wastewater treatment systems — each configured for specific wastewater types, discharge requirements, and reuse objectives.
Treats industrial process effluent containing BOD, COD, suspended solids, oil & grease, heavy metals, and specific industrial pollutants to meet CPCB/SPCB discharge consent conditions or reuse standards.
Treats domestic sewage and mixed wastewater using biological processes to reduce BOD, COD, ammonia, and pathogens — producing treated effluent suitable for discharge or reuse in non-potable applications.
Polishes treated ETP/STP effluent to a quality suitable for reuse in industrial cooling, utility water, process reuse, irrigation, flushing, or gardening — reducing freshwater dependency and discharge load.
Recovers usable process water from high-volume or high-value wastewater streams in manufacturing — reducing raw water consumption and treatment costs while improving water balance across the facility.
Advanced tertiary treatment and polishing systems that upgrade treated effluent to meet specific reuse quality standards — including colour, turbidity, BOD, and microbial control — for industrial, commercial, or environmental applications.
Every untreated or incorrectly treated wastewater challenge carries operational, financial, and regulatory risk. CLEANFLO identifies the root cause and engineers the right solution.
High organic loads overwhelm biological treatment, causing consent limit breaches, fish kill risk, and CPCB/SPCB enforcement notices.
Excessive TSS causes downstream membrane fouling, high sludge generation, and increased disposal cost — especially for industries with seasonal production spikes.
Oil and grease coat biological media and membranes, inhibit biological treatment, and cause non-compliance with effluent oil content limits.
Reactive dyes and toxic organics are resistant to conventional biological treatment, causing colour-in-discharge violations and reuse quality failures.
Heavy metals (chromium, nickel, zinc, lead) in effluent are toxic to aquatic life, bio-accumulate, and face strict CPCB Schedule I limits that are frequently violated.
Inadequately disinfected treated sewage carries pathogenic risk in reuse applications — for flushing, gardening, and process use — and faces increasingly strict coliform limits.
Seasonal production peaks or batch discharge events overwhelm treatment plants designed for average loads, causing exceedances during peak periods.
A complete multi-stage treatment toolkit — from pre-treatment through primary, biological, tertiary, reuse and sludge management. Select a stage to explore.
Coarse and fine screens remove large solids and fibres; grit chambers settle inorganic particles before biological stages.
Buffer tanks dampen flow and load fluctuations from batch or seasonal production — protecting downstream treatment from shock loads.
pH correction of acidic or alkaline effluents to the biological treatment operating range (pH 6.5–8.5) using acid or alkali dosing systems.
API separators, CPI interceptors, and grease traps remove free and emulsified oils before they inhibit biological processes or foul membranes.
Chemical coagulants (alum, ferric chloride, PAC) destabilize colloidal particles, enabling floc formation for subsequent removal.
Gentle mixing with polymers aggregates destabilized particles into larger, settleable flocs — improving clarifier performance.
Lamella settlers and circular clarifiers separate floc from treated effluent by gravity, producing clear overflow and concentrated sludge underflow.
Pressurized air bubbles float suspended solids, fats, oils, and grease to the surface for skimming — particularly effective for food, pulp, and paper effluents.
Suspended biomass aerobic treatment for high-volume, moderate-strength wastewater. Reliable and well-proven for most industrial and municipal applications.
Biofilm on plastic carriers treats wastewater in a compact footprint with less sensitivity to load variations — suitable for retrofitting existing tanks.
Flexible, single-tank batch process suitable for variable flows and loads; provides good nitrification/denitrification in a compact system.
Combines activated sludge with ultrafiltration membranes — producing high-quality effluent suitable for direct reuse in a smaller footprint.
Removes residual suspended solids and turbidity from biologically treated effluent before downstream membrane or reuse systems.
Adsorbs residual colour, odour, taste, and trace organic compounds — producing clean, non-objectionable treated water for sensitive reuse applications.
Membrane polishing removes bacteria, colloids, and fine particulates to SDI <3
Final pathogen control using UV irradiation, sodium hypochlorite, or chlorine dioxide to meet coliform limits for reuse or discharge.
Fenton's reaction, ozone, or UV-peroxide for degradation of recalcitrant organics, reactive dyes, and pharmaceutical compounds resistant to biological treatment.
Tertiary treatment train configured to produce reclaimed water meeting BIS/IS:16193 or site-specific reuse standards for cooling, flushing, or industrial process use.
RO concentrate reduction as the first stage of ZLD — recovering 70–80% of tertiary treated effluent as permeate for reuse, and producing a concentrated reject stream for further treatment.
High-pressure RO and mechanical vapour recompression (MVR) evaporators further concentrate ZLD brine to reduce evaporation load and crystallizer size.
Final ZLD stage converts concentrated brine to dry solids for disposal — completing the zero liquid discharge cycle and enabling regulatory compliance.
Gravity thickeners or mechanical thickeners reduce sludge volume before dewatering — reducing energy and reagent costs in downstream processes.
Belt filter presses, filter presses, or centrifuges dewater thickened sludge to 20–35% dry solids — significantly reducing disposal weight and transport cost.
Process optimisation and chemical conditioning strategies to reduce sludge generation at source, lowering long-term disposal spend.
Guidance on compliant disposal routes — landfill, incineration, or permitted utilisation — in accordance with Hazardous Waste Rules and CPCB guidelines.
A structured, seven-step engineering workflow ensures every wastewater treatment plant is designed, built, and operated to perform reliably across all conditions.
Wastewater sampling, laboratory analysis of BOD, COD, TSS, oil & grease, heavy metals, nitrogen, phosphorus, and specific industry parameters. Flow profiling across production shifts and seasons.
Treatment train selection based on wastewater type, discharge or reuse standards, site footprint, and capital vs operating cost balance. Preliminary sizing and technology comparison report.
Laboratory-scale validation of chemical doses, biological process, and polishing steps before full-scale design is finalised. Reduces risk and confirms performance expectations.
Supply of tanks, aerators, pumps, media, membranes, clarifiers, and control systems. After in depth engineering to meet the Requirements.
Technical supervision during installation. Plant startup, biological seed inoculation, chemical dosing commissioning, and performance testing against baseline inlet and outlet quality targets.
Hands-on operator training for biological process management, chemical dosing, sludge handling, alarm response, and routine maintenance. Written SOPs and daily monitoring checklists provided.
Periodic site visits, influent and effluent monitoring, chemical program review, and performance trend analysis — identifying and correcting deviations before they become compliance issues.

Illustrative scenarios representing the type of outcomes CLEANFLO's integrated approach delivers across different industries and system types.
A textile dyeing plant under CPCB ZLD mandate was discharging high-colour effluent with non-compliant BOD. CLEANFLO designed and commissioned a combined ETP + RO + evaporation system — achieving ZLD compliance and reusing 80%+ of water for cooling and gardening.
A food processing plant was receiving notices for consistent BOD exceedances due to seasonal production peaks overwhelming its original ETP. CLEANFLO's equalization and MBBR upgrade resolved the overload issue — sustaining compliance through peak season without expanding the plant footprint.
A large office campus with an underperforming STP was disposing all treated water — missing an opportunity to reuse it for flushing and landscaping. CLEANFLO upgraded the STP with tertiary filtration and UV disinfection, enabling the campus to reuse 60% of treated water and significantly reduce its municipal water bill.
