ERGIL builds equipment for water and wastewater treatment: multimedia, sand and activated carbon filters, demineralization units, dosing and neutralization systems, flotation units, clarifiers, sludge handling and produced water packages.
To protect water pipelines against water hammer, see our surge vessels.
Water Industry Products
- Sour Water Treatment Package: Skid-mounted package that strips H2S and NH3 from refinery and gas plant sour water.
- Deoiling Hydrocyclone Package: Compact skid that reduces oil in produced water for discharge or reinjection.
- CPI + Dissolved Gas Flotation Package: Removes free and dispersed oil from process and produced water in one skid.
- Multimedia Filter Package: Multi-layer filtration vessel using anthracite, sand, and garnet for suspended solid removal in pre-treatment applications.
- Sand Filter Vessel: Pressure vessel filled with graded sand media for removing suspended solids, turbidity, and fine particulates from raw or process water.
- Activated Carbon Filter Vessel: Removes chlorine, organics, and color from process and feedwater streams.
- Degas / Deaerator Vessel: Removes dissolved gases (O₂, CO₂) from water to prevent corrosion and scaling in high-purity systems.
- Demineralization Unit (Cation/Anion Exchange): Two-bed ion exchange system for producing low-conductivity demineralized water.
- pH Correction & Dosing Skid: Automated skid for pH control using acid/caustic dosing and inline monitoring.
- Neutralization Tank & Mixer: Reactor vessel for neutralizing acidic or alkaline wastewater prior to discharge or reuse.
- Dissolved Air Flotation (DAF) Unit: System for separating suspended solids, oils, and greases using micro-air bubbles; ideal for industrial wastewater.
- Clarifier / Settling Tank: Gravity separation tank designed to remove suspended solids and sludge from raw or process water.
- Sludge Hopper & Dewatering Skid: Collects and dewaters sludge from water-treatment plants using pumps and filter-press integration.
- Chemical Storage Tank (HDPE/GRP Lined): Corrosion-resistant tank for storage of treatment chemicals such as NaOH, H₂SO₄, or antiscalants.
- Backwash Recovery Tank: Tank for collecting and reusing backwash water from multimedia or carbon filters to minimize waste.
- Odor Control Scrubber: Wet scrubber for removing H₂S and VOCs from wastewater plant off-gas.
- Equalization Tank: Balances flow and concentration fluctuations before biological or chemical treatment, ensuring steady operation of downstream water treatment processes.
- Sludge Holding Tank: Cylindrical tank designed to store and homogenize thickened sludge prior to dewatering, equipped with mixers or agitation systems to prevent settling.
- Chemical Preparation Tank: Mixing and dosing vessel used to prepare polymer, coagulant, or neutralizing chemicals for feed into the treatment system; available in SS or HDPE.
- Buffer Tank: Intermediate storage vessel that stabilizes process flow and pressure between filtration and polishing stages in ultrapure water systems.
- Activated Carbon Water Recovery Tank: Activated carbon filtration vessel designed for polishing recovered water by adsorbing organic impurities before reuse or discharge.
- Chemical Cleaning Multimedia Filter: Multi-layer filtration vessel designed for removing suspended solids and turbidity from chemical recovery circuits in ultrapure water systems.
- Chemical Cleaning Activated Carbon Filter: Activated carbon vessel used to remove organic contaminants and chlorine residues during chemical cleaning or rinse processes.
- Cooling Water Return Activated Carbon Filter: Carbon filtration unit for cooling water polishing, removing organic and residual contaminants prior to reuse in closed-loop systems.
- Cooling Water Return Multimedia Filter: Pressure vessel equipped with graded sand and anthracite layers to remove turbidity and suspended solids from cooling water return.
- Line Supply Return Activated Carbon Filter: Activated carbon filter designed for polishing line-supply water, eliminating organic compounds and odor-causing agents.
- Air Washer Return Activated Carbon Filter: Carbon vessel for air washer or scrubber water treatment, removing volatile organics and odor-forming contaminants.
- Air Washer Return Multimedia Filter: Multimedia filter vessel used in HVAC and air washer systems for suspended solids removal and water clarity improvement.
