Out Line

Focus Subject WWTP Life cycle WWTP Current Condition WWTP in Great Idea

Focus Subject Aquasim Software, this is the basic software for

building a new system and study how to input some of the variables to make the wastewater treatment system complete which results in perfect result effluent condition

Biowin Software, is a simulation program. It simulates an operational system with new probabilities based on mathematical formulae

WWTP Lifecycle

System choice

Problem solving

Future prognosis

Preliminary design

Final design

Functional design

Operator education

Wwtp start-up

optimization

Reduced Saving

Low possible saving e.g cost of bulking sludge

Large possible savings e.g choice surface or bubble aerator

Medium possible savings e.g cost of reduced effluent quality

Very large possible savings e.g. choice membrane or conventional system

What about our WWTP now?

± 8.000 m3 every day 300 Ton Sludge production every year Disposal Cost: Rp.3.000.000.000 every

year Effluent discharge quality based on KLH

regulation

Challenges…….

The main idea is?

Considerable………

Possibility for the future

Wase water

New Water

Bio Gas

Breakthrough Idea……..

Use New Improvement in Purifying water By Electro Coagulation System

Re- Use Sludge become BIOGAS

What is Electro Coagulation?

The Idea is come from electrolysis process

There are some MAIN UNIT that must be developed, they are :

a. Chamber

b. Electroplating

c. Variable process control System

Block Process Electro Coagulation

Become Organic Sludge

Only sugar needed

Sludge

New water (W-1)

Electro Coagulant

New water (W-2)

Waste Water TUNEL

Benefit Using Electro Coagulant System

Simple Process Low Cost Investment High Quality Product Low maintenance Long term Life Time

Weakness point in Electro Coagulant

There are problem with chemical suppliers , cause much of their product no need anymore

There are problem with “ Departement Tenaga Kerja” cause the system no need much person

How about Sludge..????

Sludge will changes become organic sludge cause only sugar fill in

Sludge processing by An Aerobe System And then just collect the methane gas

(Simple Process)

Benefit An Aerobic System

Reduce for Yearly Disposal Cost Sludge

Reduce Maintenance Sludge such as: Land and Operator cost

Take much Revenue From GAS Methane (predicted)

Weaknes Poin Use An Aerobic System

Need New Investment and Research

Need expert Bio Gas Engineer

Need Extremely Business Policy

Sustainable Quality Sustainable Business
