An An Industrial Water Treatment Plant (Industrial WTP) is a specialized water purification system designed to treat raw water from sources such as borewells, rivers, lakes, municipal supplies, and surface water and convert it into high-quality water suitable for industrial applications. It removes impurities such as suspended solids, dissolved salts, hardness, heavy metals, organic contaminants, and microorganisms using treatment technologies such as filtration, sedimentation, water softening, ultrafiltration (UF), reverse osmosis (RO), nanofiltration (NF), demineralization (DM), UV, and ozone treatment. The treated water can be used for process water, boiler feed water, cooling towers, manufacturing, washing, and other industrial requirements while helping protect equipment from scaling and corrosion, reduce water consumption, and support water reuse and sustainable industrial operations.
As an experienced industrial water and wastewater treatment plant manufacturer, Envocare Projects & Services designs, manufactures, supplies, installs, commissions, and provides operation and maintenance support for a wide range of water and wastewater treatment systems. Our treatment plants are engineered and manufactured according to specific feed-water quality, process requirements, treatment objectives, water-reuse needs, and applicable discharge standards. Our manufacturing and engineering capabilities cover conventional water treatment, advanced membrane systems, ion-exchange technologies, industrial wastewater treatment, water recycling, and zero liquid discharge solutions:
By combining these technologies according to site-specific requirements, Envocare Projects & Services delivers complete industrial water and wastewater treatment solutions — from raw-water treatment and process-water purification to effluent recycling and zero liquid discharge.
As Industrial Water Treatment Plant Manufacturers in Pune, we follow a structured multi-stage treatment approach that efficiently transforms raw water into reusable or safe discharge water through physical, chemical, biological, and advanced purification processes.
| Step | Steps of an Industrial Water Treatment Plant | Description |
|---|---|---|
| 01 | Pre-Treatment (Screening & Equalization) | Raw water is screened to remove debris and passed through equalization tanks where oils and grease are separated. |
| 02 | Primary Treatment (Coagulation & Sedimentation) | Chemicals are added to form flocs, which settle in clarifiers through the Sedimentation Process as sludge, leaving clearer water. |
| 03 | Secondary Treatment (Biological Treatment) | Microorganisms break down organic pollutants in aeration tanks, improving water quality. |
| 04 | Tertiary Treatment (Filtration & Softening) | Fine filtration and ion exchange remove remaining particles and perform effective Hardness Removal of minerals causing water hardness. |
| 05 | Advanced Treatment (RO / UF / NF Systems) | Membrane systems remove dissolved salts, bacteria, and micro-contaminants through advanced Water Purification System technologies for high purity water. |
| 06 | Disinfection & Output (UV / Ozone Treatment) | Final treatment using an advanced Disinfection System ensures safe water for reuse in processes or controlled discharge. |
| 07 | Sludge Handling (Dewatering & Disposal) | Collected sludge is treated, dewatered, and safely disposed or reused where applicable. |
Our water and wastewater treatment plants are designed with application-specific technologies to deliver reliable treatment, efficient operation, and consistent water quality. The table below highlights the key technical specifications across different plant types and treatment systems.
