CQM Solution Overview

Improve Efficiency

SR-CT ATCS

Two Pronged Approach

1. Keep Condenser Tubes Clean Automatic Tube Cleaning System (ATCS)

2. Manage Water Chemistry Scale Removal System (SRS)

Automatic Tube Cleaning System

• Condenser Ball cleaning technology has existed for 50 years and is a well accepted principle.

• However, CQM has intensified ATCS technology

(Patented) to level where it meets fullest potential in energy savings contribution.

AUTOMATIC TUBE CLEANING SYSTEM (ATCS)

All balls are injected at once

Balls reach the tube sheet at the same time Balls randomly disperse cleaning central and peripheral tubes

Ball travel does not interfere with condenser water flow

No moving parts in ball trap with absolutely zero loss of sponge balls

Balls do not pass through the pump

Screen with round holes, balls can not escape

Simple PLC operation from the control room

Ball trap with very big open area to collect the balls

No need to count the balls

C.Q.M

SRCT-LS - Large scale (NCT) Non Chemical Treatment system for cooling towers water

treatment in Power Plants

• In all Thermal power plants water is used for steam generation as well as cooling media for different circuits.

• Maintaining clean and desired quality of water is very important in the power plants as the source of water is river, underground or sea.

• The desired quality of water is achieved in power plants traditionally by treating the water with various types of chemicals, which are hazardous and causes environmental issues.

• SRCT is online treatment of cooling tower water absolutely without use of any chemicals and the results achieved by this method are better than the chemicals used traditionally.

• Best part of this technology is that it is green technology, we are not using any chemicals for the treatment of water. SRCT maintains 100% water disinfection, no bacteria and prevents growth of algae in power plant water circuits.

New Technology from CQM

• For the past 10 years CQM have installed more then 800 SRCT (non chemical electrolysis system) for small to medium size cooling towers.

• The technology replace any use of chemicals in the treatment of cooling tower water.

• The New SRCT - LS (large Scale) is a new concept and design based on the above proven product design to meet the challenges of very large scale cooling towers in power stations and refinery.

• First mid size (4500m3h / 20,000GPM) was successfully run over past two years in Auxiliary cooling tower in a power station belong to ZEG Group in China.

• Based on successful results over two year period ZEG Group has purchased from CQM in 2014 an SRCT - LS for the treatment of 2 X 600MW cooling tower project estimate at $4M, two cooling towers of 70,000 m3h/ 320,000GPM each.

Deposits of salts, corrosion, dirt and micro-organisms reduce the efficiency of cooling

towers and water circuits

And increase electricity and water consumption and accelerate the deterioration of the

equipment and tubes

Chemicals used for water treatment require to maintain the water conductivity level at

max 2500 µs, which implies a high level of bleed-off

Water consumption of ~ 20 m3/day* to compensate bleed-off (500TR cooling tower operating 18 hrs/day)

* asumming fresh water conductivity of 300 µs

SRCT -LS Chemical-free Water Treatment System for Automatic Scale Removal and Cleaning of

Cooling Towers and Water Circuits

Solution:

SRS: Cleaning of Sediments

SRS allows the operation of the cooling towers at 4500-5000 µs conductivity,

saving up to 50% of drained water

Water consumption of ~ 20 m3/day to compensate bleed-off (500TR cooling tower operating 18 hrs/day)

Water consumption of ~ 10 m3/day to compensate bleed-off (500TR cooling tower operating 18 hrs/day)

By eliminating the use of chemicals, SRS allows the saving of 100% of bleed-off that can be

applied for watering or other uses

SRS maintains water circuits free of deposits, the most efficient and technological technology

• Automatic operation

• Active oxidation

• Electrolytic technology

• Removes susp, solids

• Strong Oxidation

100% productivity

removes cor rosion

zero chemicals

zero dir t
