Wastewater Treatment Facilities

Treatment of Drainage Water and Municipal Solid Waste Landfill Leachate

As part of the comprehensive reclamation of municipal solid waste landfills, leachate is collected from the landfill body, along with drainage water from the surface of the landfill’s impermeable liner. 

Municipal solid waste landfill leachate is a toxic liquid containing organic substances, heavy metals and nutrients such as phosphates. It therefore cannot be discharged onto the ground or into a water body without thorough multistage treatment. 

To treat landfill leachate and drainage water, we use advanced membrane technology—reverse osmosis—which retains up to 99% of all organic and inorganic impurities. 

Treatment Facilities at Industrial Enterprises

We address the treatment of mine, quarry, formation and waste-rock dump water, and implement water recycling systems at mining and mineral processing enterprises.

As a rule, mine, quarry, formation and waste-rock dump water has elevated concentrations of several groups of chemical compounds: nitrogen compounds, petroleum products, heavy metal ions, suspended solids and total dissolved solids.

For their treatment, we have developed and actively apply technical solutions and equipment that deliver treatment quality compliant with the requirements for discharge into water bodies designated for fisheries, while minimising capital and operating costs.

Settling ponds play an important role in treating mine, quarry, formation and waste-rock dump water. Water arriving directly from mine workings is collected and pre-clarified in these ponds.

The impermeable liner systems of such ponds are constructed using geosynthetic materials: geomembranes, geosynthetic clay liners and geotextiles. At sites with high concentrations of toxic leachate and stringent environmental protection requirements, we implement multilayer impermeable liner systems. 

An alternative to settling ponds is provided by steel or reinforced concrete receiving tanks. To prevent corrosion caused by aggressive media, our engineers offer lining with V-LOCK anchor sheets for both existing tanks and new construction.

A Comprehensive Approach to Treatment Systems

We develop effective process solutions for water treatment and purification systems at newly constructed facilities, as well as for the reconstruction and modernisation of equipment at operating enterprises.

We provide a full range of services:

• Technology selection
• Design
• Preparation of design documentation
• Equipment manufacturing and supply
• Installation and commissioning
• Service and maintenance

This approach reduces the overall project cost, improves equipment quality and reliability, and ensures warranty coverage and uninterrupted operation of water treatment and purification systems.
