FAQs
Frequently Asked Questions
Common questions about WTP, STP, ETP systems, compliance, and our services
What types of water treatment plants does Greenify provide?
Greenify provides comprehensive water treatment solutions including WTP (Water Treatment Plants) for drinking water purification, STP (Sewage Treatment Plants) for domestic wastewater from residential and commercial buildings, and ETP (Effluent Treatment Plants) for industrial wastewater. We also offer ZLD (Zero Liquid Discharge) systems, packaged plants, and modular solutions.
What is the difference between STP and ETP?
STP (Sewage Treatment Plant) treats domestic sewage from residential complexes, hotels, hospitals, and commercial buildings. It handles wastewater with organic pollutants (BOD/COD) and pathogens. ETP (Effluent Treatment Plant) treats industrial wastewater containing chemicals, heavy metals, dyes, and process-specific pollutants. ETPs require customized treatment based on industry type.
What industries require ETP installation?
Industries mandated to install ETPs include textile & dyeing, pharmaceutical, food processing, chemical & petrochemical, paper & pulp, leather tanning, metal finishing, automotive, distilleries, and any industry generating trade effluent. CPCB and State Pollution Control Boards enforce compliance.
What is the ETP treatment process?
ETP treatment involves multiple stages: 1) Screening & Equalization to remove solids and balance flow, 2) Primary Treatment with coagulation, flocculation, and sedimentation, 3) Secondary/Biological Treatment using activated sludge, MBR, or SBR for organic removal, 4) Tertiary Treatment for polishing, and 5) Disinfection before discharge or reuse.
What is the capacity range of Greenify water treatment plants?
Our water treatment solutions range from 10 KLD (Kiloliters Per Day) for small commercial applications to 50 MLD (Million Liters Per Day) for large municipal and industrial projects. We design plants based on actual wastewater generation, peak flows, and future expansion requirements.
Does Greenify provide IoT monitoring for water treatment plants?
Yes, all our plants can be equipped with IoT sensors for real-time monitoring of pH, BOD, COD, TSS, TDS, turbidity, and flow rates. Our cloud-based MeterSync dashboard provides 24/7 visibility, automatic alerts, and compliance reporting for pollution control boards.
Are Greenify's water treatment plants CPCB compliant?
Yes, all our WTP, STP, and ETP solutions are designed to meet CPCB (Central Pollution Control Board) and MoEFCC (Ministry of Environment, Forest and Climate Change) discharge standards. We provide complete assistance with regulatory compliance, testing, and certification.
What is Zero Liquid Discharge (ZLD) and do you provide it?
ZLD is a water treatment process that eliminates liquid waste discharge by recovering all water for reuse. It involves RO, evaporators, and crystallizers to convert wastewater into clean water and solid residue. We provide ZLD solutions for industries where discharge is prohibited or water recovery is economically beneficial.
How long does it take to install a water treatment plant?
Installation timeline depends on plant type and capacity. Small packaged STPs (10-50 KLD) can be installed in 4-6 weeks. Medium-sized plants (50-500 KLD) take 8-12 weeks. Large custom ETPs and ZLD systems may require 16-24 weeks including civil work, equipment installation, and commissioning.
Do you provide AMC and O&M services?
Yes, we offer comprehensive Annual Maintenance Contracts (AMC) and full Operation & Maintenance (O&M) services. This includes preventive maintenance, consumables supply, 24/7 technical support, emergency response within 4 hours, and monthly compliance reports.
What membrane technologies do you offer?
We provide complete membrane solutions including Reverse Osmosis (RO) for desalination and demineralization, Ultrafiltration (UF) for pre-treatment and bacteria removal, Nanofiltration (NF) for selective separation, and Membrane Bioreactor (MBR) for wastewater treatment. We also offer specialized membranes for brackish water and seawater applications.
What is the difference between RO, UF, and NF membranes?
RO (Reverse Osmosis) removes dissolved salts and operates at high pressure (10-70 bar) with pore size <0.001 microns. UF (Ultrafiltration) removes bacteria and colloids at low pressure (1-5 bar) with 0.01-0.1 micron pores. NF (Nanofiltration) is between RO and UF, removing hardness and color while allowing some minerals to pass, operating at 5-20 bar with 0.001-0.01 micron pores.
How does Zero Liquid Discharge (ZLD) work?
ZLD is achieved through a multi-step process: 1) Primary treatment and equalization, 2) Biological treatment if required, 3) High-recovery RO (75-85%), 4) Brine concentration using EDR or membrane concentrators (up to 95%), 5) Evaporation using MEE/MVR, and 6) Crystallization for salt recovery. The result is 100% water recovery and dry solid waste.
What is the cost of a ZLD system?
ZLD system costs depend on effluent volume, TDS, and characteristics. Typical CAPEX ranges from ₹50-150 lakhs per KLD of capacity for thermal ZLD. Membrane-based ZLD (MZLD) with high-recovery RO can reduce costs by 30-50%. Operating costs include power (15-30 kWh/KL for thermal, 3-8 kWh/KL for membrane) and chemical consumption.
What industries need demineralization (DM) plants?
Industries requiring ultra-pure water include power plants (boiler feed), pharmaceuticals (WFI - Water for Injection), electronics/semiconductors, food & beverage, textile (dyeing), and chemical manufacturing. DM plants using ion exchange achieve conductivity <1 µS/cm, which can be further polished to <0.1 µS/cm for critical applications.
