ROSERVE WASTEWATER RECYCLE

SOLUTIONS

PAY AS YOU TREAT!

Introduction To Roserve• Reverse Osmosis + Service = Roserve • Roserve is a Joint Venture between Danish Climate Investment

Fund (DCIF) and Concord Enviro Systems • We aim to offer Wastewater Recycle Solutions to Industries

reducing the consumption of Fresh Water / Ground Water & moving towards Zero Liquid Discharge (ZLD) • Roserve provides a blend of advanced technology and financial

solutions delivering a ’Pay as you Treat’ solution • The Solution shifts the responsibility of wastewater management

to Roserve including Investment, Operations & Compliance.

Our Experience

Textile Effluent• Textile Effluent contain Dyes, Chemicals, &

Other Impurities which are non conducive to Discharge. Processes such as Indigo Dyeing and Printing further contribute to complex organic pollutants such as inks, finishing chemicals, and other non biodegradable or difficult to treat constituents.

• While Primary & Secondary Treatment can remove colour and most of the organics from the effluent, the discharge of effluents to the environment can pollute fresh water resources mainly due to increase in salinity and associated problems such as increased SAR (Sodium Absorption Ratio)

Our Solution• Absolute Filtration using Membranes for water recycle and

consequent Zero Liquid Discharge provide the best options from a Safe Environment Impact perspective • The treatment philosophy followed is to recycle the wastewater to

the process using the Lowest Energy and keeping the cost of recycled water to the lowest possible

• With Increasing scarcity & cost of fresh water and Reducing cost of treatment & recycle, Cost of Recycled Water will be the lowest in the long term

Cost of Recycled Water

= Cost of Wastewater Treatment & Recycle

- Cost of Fresh Water Replaced

Our Solution• We therefore deploy Reverse

Osmosis Directly after the E T P u s i n g o u r H y b r i d M e m b r a n e M o d u l e Configurations to recycle 94% t o 9 8 % w a t e r u s i n g multistage RO plants. • The residue of the RO

Advantages of the Roserve Model• Service Concept: No Upfront Capital Investment / Investment in Non Core Assets.

Pay as you Use! Most Importantly Costs are Guaranteed!

• Customized Solutions: Each solution is specifically designed keeping in mind the requirement of the client. Flexibility to start with part effluent recycle and achieve ZLD over your target period

• Customer buys nothing – defines need & scope. Service agreement period > 3 years < 10 years.

• Technology Risk: The pay per use model transfers the risk of technology selection to the service provider. Roserve brings the best suited technologies such as RO/MEE/Dryers etc.

• Focus on core business: Recycle / ZLD operations handled by Roserve team deployed at customer’s premises.

• Structured contracts to meet your current operational costs

Advantages of Recycle & ZLD• Reduce your dependence on fresh water / ground water. • Increase compliance to both local government and

customer requirements. • Recycling allows you to meet 80-90% of your total daily

water consumption. Reducing your intake of fresh water significantly. • Reduce pollution and ground water contamination

Roserve Engagement structures• Roserve engages with customers in flexible structures

through BOOT / Rental / Operating Lease arrangements or simply directly purchasing the systems. • At the end of the contract period the equipment can be
