We provide a comfort factor for our
clients by continuously cultivating strong in
- house expertise. As well as latest
technology from our various principals.
The range of expertise in the company
covers Chemical, Biological, Mechanical,
Civil and Electrical Engineering.
Water and Wastewater Treatment
involves technology. Technology is forever evolving. In the interest of keeping
abreast with new and better technologies, we remain in close working relations with our principals from the US and
Europe. Although for most applications
our local team is more than equipped to
provide effective solutions, we offer the
additional bonus of being able to draw

Reverse Osmosis Process
Bali Pecatu Graha
Located in the resort island of Bali, this 300
hectare luxury estate, complete with a 36hole Golf course, requires a freshwater supply
of 3,000 m3/day for it’s Convention Centre,
Hotels, Luxury apartments and watering of
the Golf Course.
The only reliable source of water is seawater. Using a Beach Well Intake, after passing
through a Pretreatment facility, seawater is
processed in a Reverse Osmosis Desalination
Plant (GE SWRO) with a capacity of 2 x 1,500
m3/day. The TDS (Total Dissolved Solids) of the
product water is < 200 ppm.
This complex of luxury apartments in north
Jakarta utilizes water from a nearby lake
Pantai Mutiara
which is the collection point of a number of
small rivers. Besides having a high organic
content, the TDS (Total Dissolved Solids) in the
water is between 2,000 - 4,000 ppm.
Envitech’s Water Treatment system begins
with a physico-chemical process (coagulation, flocculation, clarification) followed by
removal of organic material using Ultrafiltration
membranes. In order to bring down the TDS to
a level suitable for drinking and domestic use,
the water is then passed through a Brackish
Water Reverse Osmosis system (GE BWRO).
The final TDS of the water is < 400 ppm and is
suitable for domestic consumption.

Sentul Private Water Supply
This is a 100 litre/second conventional treatment plant to produce drinking water from a river
water supply, located near to Bogor, West Java. It is designed for expansion to 300 litres/second. This is a high-specification project with International Consultant and was won against
international competition.
The main plant is a single concrete structure consisting of two Clarifier and three Gravity filter
basins. The Clarifiers are sludge-blanket, flat-bottom type, and can handle the variable quality
of river water supply.

RECYCLE WASTEWATER TREATMENT
Unilever
This is a waste water treatment plus recycle
water treatment plant, installed at the large
Unilever production facility in Surabaya. First
stage is conventional biological treatment of
the waste water, with some tertiary treatment
to further reduce contaminants, and this is
followed by a reverse osmosis (RO) unit,
supplied as a container-mounted package
for rapid installation.
Treated water from the RO plant is of high
purity and is recycled for use as boiler feed
water. Reject water from the RO plant has
a high salt concentration and is normally
discharged to drain, but in this case Unilever
have a process use for the reject water.
As a result, the installation of this plant has
completely eliminated waste water discharge
from the factory.
There are also cost savings in reducedpurchase of PDAM water, and in boiler water
treatment cost - this resulting in a
“payback time” of less than 3 years.

Waste Water Treatment
Lippo Cikarang Industrial Estate
Lippo Cikarang was one of the first Industrial
Estate in Indonesia to have a centralized
Denpasar Sewerage
Development Project (DSDP)
Wastewater Treatment Plant. The 5,000 m3/
day wastewater treatment plant was designed to treat wastewater discharged from
various industries located in the 300 hectare
estate. More than 50% of the wastewater
consisted of high strength wastewater from
Batik Textile works. The treatment sequence
used in the plant is unique to Envitech in
that the wastewater undergoes Biological Treatment first and then followed by a
Physico-chemical stage. The discharge from
the centralized treatment plant has been
well within the government’s standard.
This current project is of interest because
when completed, Denpasar will be the first
large city in Indonesia with a major sewerage system and sewage treatment. Project finance and main contractor are from
Japan and Envitech has supplied the Aqua
Aerobics Surface Aerators which will be
installed in the large aerated lagoon.
Envitech has installed several hundred
Aqua Aerobics Aerators in Indonesia and
they have the highest reputation for
performance and reliability.
