Our Services

Waste Water & Sewage Treatment

Comprehensive solutions for managing industrial effluent and sewage, ensuring strict adherence to pollution control norms.

STP & ETP Systems (As per KSPCB norms)

Custom-engineered Sewage (STP) and Effluent (ETP) treatment plants designed to meet strict KSPCB pollution control norms.

Anaerobic, MBBR, & SBR Systems

Advanced biological treatment technologies (Moving Bed Biofilm Reactor & Sequencing Batch Reactor) utilizing bacteria to efficiently break down organic pollutants in a compact footprint.

Clarifiers & Settling Systems

Essential tanks used to separate solids from liquids through sedimentation, clarifying wastewater before further treatment.

Parallel Plate Separator & Chemical Coagulation

Physical-chemical systems designed to separate oil, grease, and suspended solids through gravity settling and chemical addition.

O&M CoClarifiers & Settling Systemstracts & AMC Services

Sedimentation tanks that slow water flow to allow sludge to settle, effectively clarifying wastewater before secondary treatment.

FRP & MS Treatment Units

Durable Fiber Reinforced Plastic (FRP) and Mild Steel (MS) tank fabrication designed for high corrosion resistance and long operational life.

Pressure Sand Filter & Activated Carbon Filter

Tertiary treatment filtration stages that remove residual suspended solids, color, and odor to polish treated water.

Ultra Filtration Plant

Membrane-based technology that removes microscopic particles and pathogens, making treated wastewater suitable for recycling (gardening/flushing).

Bio Gas Plant

Sustainable waste-to-energy systems that convert organic waste into renewable biogas for cooking or power generation.

Water Treatment Plant

Advanced filtration and purification systems designed to provide safe, clean water for domestic use, industrial processes, and aquaculture. From removing iron to high-grade Reverse Osmosis.

Pressure Sand Filter

Robust pre-treatment filter that physically captures suspended solids and turbidity from raw water.

Activated Carbon Filter

Adsorption filter used to remove chlorine, volatile organic compounds (VOCs), and unpleasant tastes or odors.

Iron Removal Filter

Specialized oxidation filtration that eliminates dissolved iron to prevent red staining on clothes and plumbing fixtures.

Water Softener

Ion-exchange system that removes hardness minerals (calcium and magnesium) to prevent scale buildup in pipes and appliances.

Industrial & Domestic RO Plant

High-performance Reverse Osmosis systems capable of rejecting up to 99% of dissolved salts for pure drinking or process water.

De Mineralised (DM) Plant

Produces ultra-pure water by removing all mineral ions, essential for industrial boilers, textiles, and electronics manufacturing.

Ammonium Removal Plant

Specialized bio-filtration designed to maintain safe ammonia levels, critical for aquaculture and fish farming health.

UV & UF System

Disinfection stage using Ultraviolet light and Ultrafiltration membranes to kill bacteria and viruses without adding chemicals.
