"Taking care of the world's water"

is more than just our claim - its our vision!

OUR VISION:

We take care of the world’s water.

OUR MISSION:

We enable our customers to improve the

quality and reduce the cost of their water

and wastewater.

OUR VALUES:

We operate safely and in environmental

compliance.

We take great care of our customers. We achieve profitable, market-leading

growth.

We treat our employees and business

partners with respect.Water Technologies

MBBR




Advantages of MBBR over Activated Sludge process

Less retention time

Less footprint

Expandable

By increasing the aeration

By media addition

Less power consumption

Less operation and maintenance

No clogging of aeration devices

No recycle loop

Less sludge production, thus, less odor

SBR advantages over Conventional process

High quality effluent at widely varying flows and loadings

600 m3/d to 40,000 m3/d

Reduced space requirements

Power savings

Simple operation and maintenance

No sludge recycling

No aeration device clogging




Bio Flow Sheet Solution




Flowsheet + Solution - A Proposal to offer SWT Technologies,Systems and Products, that are arranged in a Flowsheet that addtangible economic value to customers (reduction in energy, bio-solids, construction) and improved quality to treated effluent, givinga competitive advantage to our customers and users.

What is a Flow Sheet Solution?




Large plants – Activated Sludge process

No Primary Clarifier




Vertical Loop Reactor

VertiCel




Vertical Loop Reactor (VLR)

Vertical, thus less footprint

No mechanical mixer (power savings) No internal recycling pump

Common wall

No dedicated anoxic tank

Effectively manages peak flows(5 – 10 times the average flow)

VertiCel (VLR + Fine Bubble Cell)

No coarse bubble diffuser in VLR

Energy consumption savings

30 – 40 % < fine bubble diffusers alone

60 – 70 % < surface aerators





High Performance Clarifier




Rim Flo / Two Bro Clarifier

30 – 40 % smaller than conventional

50 – 100 % more efficient than conventional

Rapid sludge removal, thus less odor release

Sludge is more thick, require less number of digesters
